**Tolerance rationale:** Financial data uses double precision. Differences below 1e-9 stem from floating-point arithmetic order, not algorithmic divergence.
-## Validation Philosophy
-
-Three levels of confidence:
-
-**Level 1: Cross-Library Agreement**
-Multiple independent implementations produce identical results. Highest confidence. Most mainstream indicators (SMA, EMA, RSI, MACD) fall here.
-
-**Level 2: Original Source Agreement**
-No cross-library validation available, but implementation matches original research paper or patent description. JMA, various proprietary indicators fall here.
-
-**Level 3: Mathematical Correctness Only**
-No external reference exists. Implementation verified through unit tests, edge case handling, and mathematical properties (e.g., filter stability, energy preservation). Novel or obscure indicators fall here.

-## Running Validation Tests
-```bash
-# All validation tests
-dotnet test lib/QuanTAlib.Tests.csproj --filter "Category=Validation"
+## Validation Philosophy
-# Specific library comparison
-dotnet test lib/QuanTAlib.Tests.csproj --filter "FullyQualifiedName~TalibValidation"
-dotnet test lib/QuanTAlib.Tests.csproj --filter "FullyQualifiedName~SkenderValidation"
+Three levels of confidence:
-# Single indicator validation
-dotnet test lib/QuanTAlib.Tests.csproj --filter "FullyQualifiedName~EmaValidation"
-```
+**Level 1: Cross-Library Agreement**
+Multiple independent implementations produce identical results. Highest confidence. Most mainstream indicators (SMA, EMA, RSI, MACD) fall here.
+
+**Level 2: Original Source Agreement**
+No cross-library validation available, but implementation matches original research paper or patent description. JMA, various proprietary indicators fall here.
+
+**Level 3: Mathematical Correctness Only**
+No external reference exists. Implementation verified through unit tests, edge case handling, and mathematical properties (e.g., filter stability, energy preservation). Novel or obscure indicators fall here.
## Discrepancy Investigation
@@ -456,10 +533,4 @@ When validation fails:
3. **Check smoothing assumptions.** Some libraries use SMA for initial EMA seed. Others use the first value.
4. **Check edge cases.** NaN handling, zero division, and boundary conditions vary.

+- ABERR measures price deviation from a central moving average using mean absolute deviation rather than standard deviation, producing dynamic bands ...
- Parameterized by `period`, `multiplier` (default 2.0).
- Output range: Tracks input.
- Requires `period` bars of warmup before first valid output (IsHot = true).
- Validated against TA-Lib, Skender, and Tulip reference implementations where available.
-ABBER measures price deviation from a central moving average using mean absolute deviation rather than standard deviation, producing dynamic bands that adapt to volatility while remaining robust against extreme outliers. Where Bollinger Bands amplify outliers through squaring (the $L^2$ norm), ABBER uses raw absolute differences (the $L^1$ norm), so bands respond to typical price behavior rather than the occasional spike that yanks everything sideways. For a 20-period window with a 2.0 multiplier, ABBER contains approximately 89% of normally-distributed price action, but its real advantage emerges with fat-tailed distributions where standard deviation overreacts to single-bar anomalies.
+ABERR measures price deviation from a central moving average using mean absolute deviation rather than standard deviation, producing dynamic bands that adapt to volatility while remaining robust against extreme outliers. Where Bollinger Bands amplify outliers through squaring (the $L^2$ norm), ABERR uses raw absolute differences (the $L^1$ norm), so bands respond to typical price behavior rather than the occasional spike that yanks everything sideways. For a 20-period window with a 2.0 multiplier, ABERR contains approximately 89% of normally-distributed price action, but its real advantage emerges with fat-tailed distributions where standard deviation overreacts to single-bar anomalies.
## Historical Context
The absolute deviation approach predates Bollinger's work by decades. Mean absolute deviation appears in early 20th-century statistics as a robust alternative to standard deviation, championed by statisticians who recognized that squaring deviations gives disproportionate weight to outliers. In financial markets, applying absolute deviation to band construction arrived after practitioners grew tired of watching Bollinger Bands blow out on single-bar anomalies such as flash crashes, earnings gaps, and fat-finger trades.
-No single inventor claims credit for ABBER. The technique spread through trading floors where robustness mattered more than textbook elegance. The mathematical distinction is fundamental: standard deviation is a quadratic spring that amplifies outliers, while mean absolute deviation is a linear damper that treats all deviations proportionally. Under Gaussian assumptions, $\text{MAD} \approx 0.7979 \sigma$, so ABBER with multiplier 2.0 is roughly equivalent to Bollinger Bands with multiplier 1.6. But on real market data with kurtosis > 3, the gap widens in ABBER's favor.

+# MIDBODY: Open-Close Average
+
+| Property | Value |
+| ---------------- | -------------------------------- |
+| **Category** | Core |
+| **Inputs** | OHLCV bar (TBar) |
+| **Parameters** | None |
+| **Outputs** | Single series (Midbody) |
+| **Output range** | Varies (see docs) |
+| **Warmup** | `1` bars |
+
+### TL;DR
+
+Midbody computes the arithmetic mean of Open and Close prices: $(O + C) \times 0.5$. It captures where price started and ended within a bar, ignoring intra-bar extremes. No lookback period, no state, always hot after the first bar. Equivalent to `TBar.OC2`.
+
+## Historical Context
+
+The Open-Close average has no formal attribution in technical analysis literature. Unlike `HL2` (Median Price) or `HLC3` (Typical Price) which appear in TA-Lib and classic references, OC2 exists primarily as a computed property in modern libraries like Skender.Stock.Indicators (`CandlePart.OC2`).
+
+The rationale for OC2 is straightforward: Open and Close represent the consensus prices at session boundaries. High and Low represent transient extremes that may reflect noise or stops being triggered. By averaging only the session endpoints, OC2 filters out intra-bar volatility entirely.
+
+OC2 is useful as an input to trend-following indicators when you want the trend signal to reflect directional bias (where did the bar open and close?) rather than range (how far did it swing?). It also serves as the natural center for Heikin-Ashi calculations (HA Close = OHLC4, but HA state tracking uses the prior bar's OC2).
+
+## Architecture & Physics
+
+### 1. Core Formula
+
+$$\text{Midbody} = (O + C) \times 0.5$$
+
+The multiplication form avoids a division operation. The JIT compiles `* 0.5` to a single `vmulsd` instruction.
+
+### 2. State Management
+
+OC2 is stateless. Each bar's output depends only on that bar's Open and Close values. The `State` record struct tracks only:
+
+- `LastValidOpen` / `LastValidClose` for NaN substitution
+- `LastResult` for fallback when both inputs are non-finite
+- `Count` for `IsHot` tracking
+
+### 3. Complexity
+
+| Metric | Value |
+|--------|-------|
+| Time (streaming) | $O(1)$ |
+| Time (batch) | $O(n)$ |
+| Space | $O(1)$ — no buffers |
+| Warmup | 1 bar |
+
+## Mathematical Foundation
+
+### Parameters
+
+None. OC2 is parameterless.
+
+### Weight Distribution
+
+| Component | Weight |
+|-----------|--------|
+| Open | 0.5 |
+| High | 0 |
+| Low | 0 |
+| Close | 0.5 |
+
+### Comparison with Other Price Transforms
+
+| Transform | Formula | Components Used | Bias |
+|-----------|---------|:---------------:|------|
+| Midbody | $(O+C) \times 0.5$ | O, C | Session endpoints only |
+| MEDPRICE | $(H+L) \times 0.5$ | H, L | Range-centered; ignores O/C |
+| TYPPRICE | $(O+H+L) / 3$ | O, H, L | Opening-biased range |
+| HLC3 | $(H+L+C) / 3$ | H, L, C | Close-influenced range |
+| AVGPRICE | $(O+H+L+C) \times 0.25$ | O, H, L, C | Fully balanced |
+| WCLPRICE | $(H+L+2C) \times 0.25$ | H, L, C | Close double-weighted |
+
+### Pseudo-code
+
+```text
+function Midbody(bar):
+ return (bar.Open + bar.Close) * 0.5
+```
+
+### Output Interpretation
+
+- OC2 > Close: bar closed below its midpoint (bearish lean)
+- OC2 < Close: bar closed above its midpoint (bullish lean)
+- OC2 = Close: Open = Close (doji-like bar)
+
+## Performance Profile
+
+### Operation Count (Streaming Mode)
+
+| Operation | Count |
+|-----------|-------|
+| Addition | 1 |
+| Multiplication | 1 |
+| Comparison | 0 |
+| Memory access | 2 (O, C) |
+| **Total** | **4 ops** |
+
+### Batch Mode (SIMD Analysis)
+
+The batch loop is a trivial element-wise `(a[i] + b[i]) * 0.5`. Auto-vectorization by the JIT is expected for aligned spans. Manual SIMD is not implemented because the operation is already memory-bandwidth-bound at this simplicity level.
+
+## Validation
+
+| Library | Method | Tolerance | Status |
+|---------|--------|-----------|--------|
+| Skender | `CandlePart.OC2` | `1e-7` | ✅ Batch + Streaming + Span |
+| TA-Lib | N/A | — | Not available |
+| TBar.OC2 | Property | `1e-10` | ✅ All bars match |
+
+## Common Pitfalls
+
+1. **Confusing OC2 with MEDPRICE.** MEDPRICE is `(H+L)/2`; OC2 is `(O+C)/2`. They answer different questions: range center vs. session endpoint average.
+2. **Confusing OC2 with Midpoint.** Midpoint is `(Highest(V,N) + Lowest(V,N))/2` — a rolling indicator with a period parameter. OC2 has no period.
+3. **Using OC2 for volatility estimation.** OC2 deliberately ignores H and L. For volatility-aware price proxies, use HLC3 or OHLC4 instead.
+4. **Expecting TA-Lib compatibility.** TA-Lib does not implement OC2. Validation is against Skender only.
+5. **Gap analysis with OC2.** When Open and Close are nearly equal (doji bars), OC2 converges to Close. This is correct behavior, not a bug.

### TL;DR
-- TYPPRICE computes the equal-weighted average of High, Low, and Close: $(H + L + C) \times \frac{1}{3}$.
+- TYPPRICE computes the equal-weighted average of Open, High, and Low: $(O + H + L) \times \frac{1}{3}$.
- No configurable parameters; computation is stateless per bar.
- Output range: Varies (see docs).
- Requires `1` bars of warmup before first valid output (IsHot = true).
-- Validated against TA-Lib, Skender, and Tulip reference implementations where available.
+- Equivalent to `TBar.OHL3` computed property.
-TYPPRICE computes the equal-weighted average of High, Low, and Close: $(H + L + C) \times \frac{1}{3}$. This three-component mean is the most widely used "representative price" in technical analysis, serving as the default input for CCI, MFI, and many other indicators. By including Close but excluding Open, Typical Price captures both the range extremes and the settlement point, giving slightly more weight to closing action than AVGPRICE does. The calculation is stateless and costs a single FMA instruction per bar.
+TYPPRICE computes the equal-weighted average of Open, High, and Low: $(O + H + L) \times \frac{1}{3}$. This three-component mean captures the opening price and the full intra-bar range without including the settlement (Close). By excluding Close, Typical Price isolates the session's initial positioning and range extremes, making it useful as an input where you want a price representative that is independent of closing action. The calculation is stateless and costs a single FMA instruction per bar.
## Historical Context
-Typical Price became the standard price transform through its adoption by Donald Lambert in his 1980 Commodity Channel Index (CCI), which explicitly requires $(H+L+C)/3$ as its input. Gene Quong and Avrum Soudack used it in the Money Flow Index (MFI) in 1989. The TA-Lib function `TA_TYPPRICE` codified it as a standalone operation. TradingView exposes it as the `hlc3` built-in source selector.
+The OHL3 variant of Typical Price represents the average of the bar's opening level and its range extremes. Unlike the more common HLC3 formulation (which TA-Lib implements as `TA_TYPPRICE`), OHL3 excludes the closing price entirely. This makes it suitable for analysis where the settlement price should not influence the representative price, for example when studying intra-session price discovery or when the closing price is already used as a separate signal component.
-The choice of three components rather than four is not arbitrary. Excluding Open removes the overnight gap component, which reflects news-driven repositioning rather than intra-session supply and demand. For intraday analysis, this makes Typical Price a purer measure of within-session fair value than AVGPRICE. For daily bars on instruments with significant gaps (equities, futures at session boundaries), the distinction matters; for 24-hour markets (forex, crypto), it is negligible.

-In QuanTAlib, `TBar.HLC3` provides the same value as a zero-cost computed property. The `Typprice` indicator class wraps this in the streaming `ITValuePublisher` interface with bar correction, NaN safety, and event chaining.

+Skender uses the same Ehlers 2002 IIR algorithm (`Fish = arctanh(Value1) + 0.5 × Fish[1]`) with HL2 input. QuanTAlib matches Skender numerically at `1e-9` tolerance after warmup convergence. The signal line (`Trigger = Fish[1]`) also matches at `1e-9`. Tulip and Ooples use different input conventions (high/low arrays vs OHLCV), so only structural validation (finite output, correct sign direction) is asserted.

+# FISHER04: Ehlers Fisher Transform (2004 Cybernetic Analysis)
+
+> "The Fisher Transform provides clear, unambiguous turning points that make it possible to identify trend reversals." — John Ehlers, *Cybernetic Analysis for Stocks and Futures* (2004)
+
+## Introduction
+
+The Fisher04 indicator implements the revised Fisher Transform from Chapter 1 of Ehlers' 2004 book *Cybernetic Analysis for Stocks and Futures*. It converts price data into a Gaussian normal distribution using the inverse hyperbolic tangent (arctanh), producing sharp turning-point signals. This 2004 revision uses wider normalization bandwidth, gentler IIR smoothing, and a reduced arctanh multiplier compared to the original 2002 TASC article, resulting in a smoother oscillator with less noise.
+
+## Historical Context
+
+Ehlers first published the Fisher Transform in a November 2002 *Stocks & Commodities* article titled "Using The Fisher Transform." That version used a 0.66 normalization coefficient and 0.67 IIR feedback. Two years later, in *Cybernetic Analysis for Stocks and Futures* (Wiley, 2004), Ehlers revised the coefficients. The 2004 version normalizes with a full 1.0 coefficient and 0.5 IIR feedback, tightens the clamp to 0.9999, and halves the arctanh multiplier from 0.5 to 0.25. No major external library (Skender, TA-Lib, Tulip, Ooples) implements this specific 2004 variant; they all use the 2002 formulation.
+
+## Architecture
+
+### 1. Min/Max Normalization
+
+The lookback window tracks the highest high and lowest low over `period` bars using a `RingBuffer`. The raw price is mapped to [-0.5, 0.5]:
+
+$$\text{norm} = \frac{\text{price} - \text{lowest}}{\text{highest} - \text{lowest}} - 0.5$$
+
+When range is zero (flat price), `Value1` resets to 0.
+
+### 2. IIR Smoothing (Value1)
+
+The normalized value is smoothed with a single-pole IIR filter:
+
+$$\text{Value1}_t = 1.0 \times \text{norm}_t + 0.5 \times \text{Value1}_{t-1}$$
+
+Compare with Fisher (2002): $\text{Value1}_t = 0.66 \times \text{norm}_t + 0.67 \times \text{Value1}_{t-1}$
+
+### 3. Clamping
+
+Value1 is clamped to $(-0.9999, 0.9999)$ to prevent arctanh singularity:
+
+$$\text{Value1} = \text{clamp}(\text{Value1}, -0.9999, 0.9999)$$
+
+The clamped value is stored back for next iteration's IIR feedback.
+
+### 4. Fisher Transform
+
+The Fisher Transform applies arctanh with IIR feedback:
+
+$$\text{Fish}_t = 0.25 \times \ln\!\left(\frac{1 + \text{Value1}}{1 - \text{Value1}}\right) + 0.5 \times \text{Fish}_{t-1}$$
+
+The 0.25 multiplier (vs 0.5 in 2002) produces approximately half the amplitude, reducing false signals.
+
+### 5. Signal Line
+
+The signal line is the previous bar's Fisher value: $\text{Signal}_t = \text{Fish}_{t-1}$
+
+## Coefficient Comparison
+
+| Parameter | Fisher (2002) | Fisher04 (2004) |
+|-----------|---------------|-----------------|
+| Normalization | 0.66 | 1.0 |
+| IIR feedback (Value1) | 0.67 | 0.5 |
+| Clamp threshold | 0.99 → 0.999 | 0.9999 |
+| Arctanh multiplier | 0.5 | 0.25 |
+| Fisher IIR | 0.5 | 0.5 |
+
+## Performance Profile
+
+### Key Optimizations
+
+- **FMA in IIR updates**: Both Value1 IIR and Fisher IIR use `Math.FusedMultiplyAdd` for the `feedback * prev + coeff * input` pattern.
+- **Precomputed constants**: Normalization coefficient (1.0), IIR feedback (0.5), clamp threshold (0.9999), arctanh multiplier (0.25) are all `const` fields, avoiding repeated literal encoding.
+- **RingBuffer for O(1) update**: `Add` and `UpdateNewest` are constant-time; only the min/max scan is O(period).
+- **State copy pattern**: `_state`/`_p_state` record struct enables bar correction without allocation.
+- **Zero allocation**: No heap allocation in the `Update` hot path; all state is stack-promoted via local copy.
+
+### Operation Count (Streaming Mode)
+
+| Operation | Count per bar |
+|-----------|--------------|
+| Comparisons | 2 x period (min/max scan) |
+| Multiplications | 2 (normalize + arctanh multiplier) |
+| Additions | 3 (normalize offset + 2x IIR) |
+| FMA calls | 2 (Value1 IIR, Fisher IIR) |
+| Log | 1 (arctanh via `Math.Log`) |
+| Clamp | 1 |
+| Division | 1 (normalization) |
+
+### SIMD Analysis (Batch Mode)
+
+| Aspect | Status |
+|--------|--------|
+| Min/max scan | Scalar (RingBuffer-based, O(period) per bar) |
+| Normalization | Scalar (data-dependent division) |
+| Value1 IIR smoothing | Scalar (sequential IIR dependency) |
+| arctanh | Scalar (`Math.Log`, not vectorizable) |
+| Fisher IIR | Scalar (sequential dependency on previous Fisher) |
+| Vectorization potential | Low: dual IIR chain + logarithm prevents SIMD |
+
+## Validation
+
+No external library implements the 2004 Ehlers variant. Validation is performed against:
+
+- Manual step-by-step computation matching the published algorithm
+- Batch vs streaming consistency (tolerance: 1e-12)
+- Span vs streaming consistency (tolerance: 1e-12)
+- Coefficient difference verification against Fisher (2002)
+- Amplitude reduction verification (Fisher04 < Fisher in avg absolute value)
+
+## Common Pitfalls
+
+1. **Confusing 2002 and 2004 versions.** The coefficient differences are subtle but produce measurably different outputs. Using 2002 coefficients with 2004 labels (or vice versa) produces incorrect results.
+2. **Not storing clamped Value1 back.** The IIR feedback must use the clamped value, not the pre-clamp value. Failing to store back causes drift.
+3. **Expecting identical results to Fisher.** Fisher04 uses 0.25x arctanh multiplier vs 0.5x; the amplitude is roughly halved.
+4. **Using Fisher04 for high-frequency scalping.** The gentler coefficients make it slower to react than Fisher (2002). Better suited for swing trading.
+5. **Ignoring the signal line crossover.** The primary trading signal is Fisher crossing above/below its one-bar-lagged signal line.

-/// Quantower adapter for Kendall Tau-a Rank Correlation indicator.
-/// Measures ordinal association between two price sources from the same symbol.
-///
-///
-/// This adapter compares two different price sources from the same symbol (e.g., Close vs Open,
-/// Close vs Volume, High vs Low). For cross-symbol correlation, use the core
-/// Kendall class directly.
-///
-/// Output is the Kendall Tau-a coefficient, ranging from -1 to +1.
-/// Values near +1 indicate strong concordance, near -1 strong discordance.

+# quantalib Python NativeAOT Wrapper — Specification v2
+
+## 1) Objective
+
+Deliver a Python package named **`quantalib`** that exposes the entire QuanTAlib
+indicator library through a stable, versioned C ABI compiled via .NET NativeAOT.
+Python ergonomics follow pandas-ta conventions where practical.
+
+### Primary goals
+
+- Near-zero-copy interop via `ctypes` + contiguous NumPy buffers (zero-copy when inputs are already C-contiguous `float64`; otherwise one normalization copy is allowed)
+- Stable C ABI surface (`qtl_*`) with explicit major-version evolution policy for future non-Python consumers
+- Full library coverage target: all supported `Batch` methods exported using a generated manifest and validated rollout gates
+- pandas-ta-compatible function signatures for common indicators
+
+### Non-goals (initial release)
+
+- Rewriting indicator math in Python
+- pybind11 / Cython extension modules
+- GPU acceleration
+- Streaming / stateful Python classes per indicator
+- Alternate numeric dtypes (`float32`, decimal)
+- Full pandas-ta edge-case parity on day one
+
+---
+
+## 2) Scope
+
+### In scope
+
+- `python/` directory at repository root
+- NativeAOT shared library (`quantalib.dll` / `quantalib.so` / `quantalib.dylib`)
+- Single `Exports.cs` mapping all `Batch` methods to `[UnmanagedCallersOnly]` exports
+- Python package `quantalib` with loader, bridge, and indicator wrappers
+- Compatibility matrix documenting pandas-ta parity levels
+- CI matrix for `win-x64`, `linux-x64`, `osx-arm64`, `osx-x64`
+
+### Out of scope
+
+- Windows ARM64 packaging
+- Async / streaming Python APIs
+- TBarSeries / BatchInputs overloads (use flat span-based overloads only)
+
+---
+
+## 3) Design requirements
+
+1. **ABI correctness** — pointer, length, and parameter contracts are explicit and validated on both sides of the boundary.
+2. **Performance** — call QuanTAlib `Batch` methods directly; no managed allocations in the export shim beyond span construction.
+3. **ABI stability** — export names are prefixed (`qtl_*`) and versioned; existing symbols never change within a major version.
+4. **Deterministic behavior** — warmup slots filled with `NaN`; invalid inputs produce defined status codes, never exceptions.
+5. **pandas-ta compatibility** — Python names and signatures mirror pandas-ta where feasible, with documented deltas.
+6. **Thread safety** — exports are designed to be stateless and reentrant; concurrent calls are supported when each call uses distinct buffers. This must be validated by stress tests in CI.
+

+
+**Design note:** `Exports.cs` and `indicators.py` stay as single flat files.
+Internal splitting is allowed later without changing any public API or ABI.
+
+---
+
+## 5) Native ABI contract
+
+### 5.1 Calling convention
+
+- All exports use `[UnmanagedCallersOnly(EntryPoint = "qtl_")]`.
+- All exports return `int` status code.
+- All pointer parameters use C ABI-compatible primitive types only.
+- No managed exceptions ever cross the ABI boundary. Every export wraps its body
+ in a `try/catch` that returns `QTL_ERR_INTERNAL` on unhandled exceptions.
+
+### 5.2 Status codes
+
+| Code | Name | Meaning |
+|------|------|---------|
+| `0` | `QTL_OK` | Success |
+| `1` | `QTL_ERR_NULL_PTR` | Required pointer is null |
+| `2` | `QTL_ERR_INVALID_LENGTH` | `n <= 0` or output length mismatch |
+| `3` | `QTL_ERR_INVALID_PARAM` | Parameter out of valid range |
+| `4` | `QTL_ERR_INTERNAL` | Unhandled exception in managed code |
+
+Failure guarantees:
+- For validation failures (`QTL_ERR_NULL_PTR`, `QTL_ERR_INVALID_LENGTH`, `QTL_ERR_INVALID_PARAM`), outputs are untouched by contract.
+- For `QTL_ERR_INTERNAL`, output buffers are unspecified and must be treated as invalid by the caller.
+
+### 5.3 ABI signature patterns
+
+The ~290 `Batch` methods in QuanTAlib follow 9 distinct signature patterns.
+Each pattern maps to a specific C ABI template:
+
+#### Pattern A: Single-input, single-output + scalar params
+
+**C# source:** `Sma.Batch(ReadOnlySpan source, Span output, int period)`
+
+**C ABI:**
+
+```c
+int qtl_sma(double* src, int n, double* out, int period);
+```
+
+**Indicators (~130):** SMA, EMA, DEMA, TEMA, HMA, WMA, RSI, ROC, MOM, CMO,
+TSI, APO, PPO, DPO, TRIX, Fisher, Inertia, Zscore, StdDev, Variance, etc.
+
+#### Pattern B: Multi-input HLCV, single-output
+
+**C# source:** `Mfi.Batch(ReadOnlySpan high, ..low, ..close, ..volume, Span output, int period)`
+
+**C ABI:**
+
+```c
+int qtl_mfi(double* high, double* low, double* close, double* volume,
+ int n, double* out, int period);
+```
+
+**Indicators (~25):** MFI, ADL, CMF, VWAP, VWAD, ADOsc, KVO, III, WAD, VA, EOM.
+
+#### Pattern C: Multi-input OHLC (no volume), single-output
+
+**C# source:** `Bop.Batch(ReadOnlySpan open, ..high, ..low, ..close, Span destination)`
+
+**C ABI:**
+
+```c
+int qtl_bop(double* open, double* high, double* low, double* close,
+ int n, double* out);
+```
+
+**Indicators (~20):** BOP, ASI, BRAR, Avgprice, Typprice, Wclprice, Midbody,
+HA, ReverseEMA variants requiring OHLC, RVGI, DEM, etc.
+
+#### Pattern D: Multi-input HL, single-output
+
+**C# source:** `Ao.Batch(ReadOnlySpan high, ReadOnlySpan low, Span destination, int fast, int slow)`
+
+**C ABI:**
+
+```c
+int qtl_ao(double* high, double* low, int n, double* out,
+ int fast_period, int slow_period);
+```
+
+**Indicators (~10):** AO, AC, Medprice, Frama (HL overload), WillR, etc.
+
+#### Pattern E: Multi-input HLC (no volume), single-output
+
+**C# source:** `Tr.Batch(ReadOnlySpan high, ..low, ..close, Span output)`
+
+**C ABI:**
+
+```c
+int qtl_tr(double* high, double* low, double* close, int n, double* out);
+```
+
+**Indicators (~15):** TR, ATR, Etherm, GHLA, PGO, RWMA, etc.
+
+#### Pattern F: Dual-input (actual + predicted), single-output
+
+**C# source:** `Mse.Batch(ReadOnlySpan actual, ..predicted, Span output, int period)`
+
+**C ABI:**
+
+```c
+int qtl_mse(double* actual, double* predicted, int n, double* out, int period);
+```
+
+**Indicators (~25):** MSE, RMSE, MAE, MAPE, SMAPE, RMSLE, Rsquared, Huber,
+PseudoHuber, TheilU, WMAPE, LogCosh, QuantileLoss, TukeyBiweight, etc.
+
+#### Pattern G: Dual-input (source + volume), single-output
+
+**C# source:** `Obv.Batch(ReadOnlySpan close, ReadOnlySpan volume, Span output)`
+
+**C ABI:**
+
+```c
+int qtl_obv(double* close, double* volume, int n, double* out);
+```
+
+**Indicators (~12):** OBV, PVT, PVR, VF, EFI, NVI, PVI, VWMA, EVWMA, TVI, PVD.
+
+#### Pattern H: Dual-input statistics (seriesX + seriesY)
+
+**C# source:** `Correlation.Batch(ReadOnlySpan seriesX, ..seriesY, Span output, int period)`
+
+**C ABI:**
+
+```c
+int qtl_correlation(double* x, double* y, int n, double* out, int period);
+```
+
+**Indicators (~6):** Correlation, Covariance, Spearman, Kendall, Granger,
+Cointegration.
+
+#### Pattern I: Multi-output indicators
+
+**C# source (example):** `Pvo.Batch(ReadOnlySpan volume, Span output, Span signal, Span histogram, ...)`
+
+**C ABI:** Each output gets its own pointer parameter:
+
+```c
+int qtl_pvo(double* volume, int n,
+ double* out_pvo, double* out_signal, double* out_hist,
+ int fast, int slow, int signal_period);
+```
+
+**Multi-output indicators:**
+
+| Indicator | Outputs | Names |
+|-----------|---------|-------|
+| PVO | 3 | pvo, signal, histogram |
+| PMA | 2 | pma, trigger |
+| MAMA | 2 | mama, fama |
+| HtPhasor | 2 | inPhase, quadrature |
+| HtSine | 2 | sine, leadSine |
+| AOBV | 2 | fast, slow |
+| AMAT | 2 | trend, strength |
+| Stoch | 2 | K, D |
+| Stochf | 2 | K, D |
+| KDJ | 3 | K, D, J |
+| SMI | 2+ | smi, signal |
+| BBands | 3 | upper, middle, lower |
+| KChannel | 3 | upper, middle, lower |
+| DCChannel | 3 | upper, middle, lower |
+| AccBands | 3 | upper, middle, lower |
+| AtrBands | 3 | upper, middle, lower |
+| All channel indicators | 3 | upper, middle, lower |
+| Vortex | 2 | viPlus, viMinus |
+| Aroon | 1* | combined |
+
+### 5.4 Special parameter mappings
+
+Several `Batch` methods use types that cannot cross the C ABI directly.
+Each requires a specific mapping:
+
+| C# type | C ABI type | Strategy |
+|---------|-----------|----------|
+| `enum StcSmoothing` | `int` | 0 = SMA, 1 = EMA |
+| `enum WindowType` (Afirma) | `int` | Map enum ordinals |
+| `bool` (isPopulation, annualize, etc.) | `int` | 0 = false, 1 = true |
+| `int[]? lengths` (Cfb) | `int* lengths, int lengths_count` | Null-safe; null → use defaults |
+| `double[] kernel` (Conv) | `double* kernel, int kernel_len` | Caller allocates |
+| `ReadOnlySpan` (Solar, Lunar) | `long* timestamps` | Direct pointer cast |
+| `TBarSeries` overloads | **Skip** | Use flat span-based overload instead |
+| `BatchInputs`/`BatchOutput` struct overloads | **Skip** | Use flat span-based overload instead |
+
+### 5.5 Dual overloads (period vs alpha)
+
+Many IIR filters expose both `Batch(src, out, int period)` and
+`Batch(src, out, double alpha)`. Export strategy:
+
+- Primary export: `qtl_ema` — takes `int period`
+- Alpha export: `qtl_ema_alpha` — takes `double alpha`
+
+Both are exported; Python wrapper defaults to the period variant.
+
+### 5.6 Validation in each export
+
+Every export function validates before calling the inner `Batch`:
+
+1. Null checks for all required pointer parameters → `QTL_ERR_NULL_PTR`
+2. `n > 0` → `QTL_ERR_INVALID_LENGTH`
+3. Range checks on scalar parameters (e.g., `period > 0`) → `QTL_ERR_INVALID_PARAM`
+4. Semantic checks (e.g., `fastPeriod < slowPeriod` where required) → `QTL_ERR_INVALID_PARAM`
+5. `try/catch` around `Batch` call → `QTL_ERR_INTERNAL` on any managed exception
+
+### 5.7 Memory ownership rules
+
+- Input pointers are **read-only** by contract (cast to `ReadOnlySpan`).
+- Caller allocates **all** output buffers with length `n`.
+- Native layer writes exactly `n` values per output buffer on success.
+- No ownership transfer across boundary. No heap allocation in the shim.
+
+### 5.8 ABI versioning policy
+
+- All exports use the flat `qtl_` prefix for v1.
+- Existing published symbols are immutable within ABI major v1.
+- New optional parameters require new symbol names (e.g. `qtl_ema_alpha`).
+- Deprecation policy: old symbols remain exported for at least one minor release after replacement and are marked deprecated in Python wrappers.
+- First breaking ABI revision introduces `qtl2_` prefix and parallel support window.
+
+### 5.9 Export manifest (authoritative source)
+
+To reduce drift across `Exports.cs`, `_bridge.py`, and `indicators.py`, maintain one machine-readable manifest (e.g., JSON/YAML) containing:
+
+- indicator name and export symbol
+- input pattern (A–I or special)
+- parameter schema (name, type, defaults, constraints)
+- output schema (count, names, order)
+
+Generated artifacts from this manifest are preferred over hand-maintained parallel lists.
+
+### 5.10 Concrete export example
+
+```csharp
+// StatusCodes.cs
+file static class StatusCodes
+{
+ public const int QTL_OK = 0;
+ public const int QTL_ERR_NULL_PTR = 1;
+ public const int QTL_ERR_INVALID_LENGTH = 2;
+ public const int QTL_ERR_INVALID_PARAM = 3;
+ public const int QTL_ERR_INTERNAL = 4;
+}
+
+// Exports.cs (excerpt)
+[UnmanagedCallersOnly(EntryPoint = "qtl_sma")]
+public static unsafe int Sma(double* src, int n, double* output, int period)
+{
+ if (src == null || output == null) return StatusCodes.QTL_ERR_NULL_PTR;
+ if (n <= 0) return StatusCodes.QTL_ERR_INVALID_LENGTH;
+ if (period <= 0) return StatusCodes.QTL_ERR_INVALID_PARAM;
+ try
+ {
+ var srcSpan = new ReadOnlySpan(src, n);
+ var outSpan = new Span(output, n);
+ QuanTAlib.Sma.Batch(srcSpan, outSpan, period);
+ return StatusCodes.QTL_OK;
+ }
+ catch { return StatusCodes.QTL_ERR_INTERNAL; }
+}
+
+[UnmanagedCallersOnly(EntryPoint = "qtl_bbands")]
+public static unsafe int Bbands(
+ double* src, int n,
+ double* outUpper, double* outMiddle, double* outLower,
+ int period, double multiplier)
+{
+ if (src == null || outUpper == null || outMiddle == null || outLower == null)
+ return StatusCodes.QTL_ERR_NULL_PTR;
+ if (n <= 0) return StatusCodes.QTL_ERR_INVALID_LENGTH;
+ if (period <= 0) return StatusCodes.QTL_ERR_INVALID_PARAM;
+ try
+ {
+ var srcSpan = new ReadOnlySpan(src, n);
+ var upper = new Span(outUpper, n);
+ var middle = new Span(outMiddle, n);
+ var lower = new Span(outLower, n);
+ QuanTAlib.Bbands.Batch(srcSpan, upper, middle, lower, period, multiplier);
+ return StatusCodes.QTL_OK;
+ }
+ catch { return StatusCodes.QTL_ERR_INTERNAL; }
+}

+## 6) Python contract
+
+### 6.1 Package identity
+
+| Property | Value |
+|----------|-------|
+| PyPI name | `quantalib` |
+| Import name | `quantalib` |
+| AssemblyName | `quantalib` |
+
+### 6.2 Loader (`_loader.py`)
+
+- Detect OS + architecture at import time.
+- Load bundled shared library from `quantalib/native//`.
+- Platform directory mapping:
+
+| Platform | Directory |
+|----------|-----------|
+| Windows x64 | `native/win_amd64/quantalib.dll` |
+| Linux x64 | `native/linux_x86_64/quantalib.so` |
+| macOS ARM64 | `native/macosx_arm64/quantalib.dylib` |
+| macOS x64 | `native/macosx_x86_64/quantalib.dylib` |
+
+- On failure: raise `OSError` with actionable message listing expected path
+ and detected platform.
+- Use explicit package-path loading; never rely on system library search order.
+
+### 6.3 Bridge (`_bridge.py`)
+
+- Declare `argtypes` and `restype` for every native function at module level.
+- Validate function presence at import time (graceful `AttributeError` → skip).
+- Input normalization: `np.ascontiguousarray(arr, dtype=np.float64)`.
+- Status code checking: helper raises Python exception mapped from return code:
+
+```python
+class QtlError(Exception):
+ """Base exception for quantalib native errors."""
+
+class QtlNullPointerError(QtlError): ... # status 1
+class QtlInvalidLengthError(QtlError): ... # status 2
+class QtlInvalidParamError(QtlError): ... # status 3
+class QtlInternalError(QtlError): ... # status 4
+```
+
+### 6.4 Indicator wrappers (`indicators.py`)
+
+- Expose pandas-ta-compatible function signatures where practical.
+- Return types:
+
+| Input type | Output (single) | Output (multi) |
+|------------|-----------------|----------------|
+| `pd.Series` | `pd.Series` | `pd.DataFrame` |
+| `pd.DataFrame` | `pd.Series` | `pd.DataFrame` |
+| `np.ndarray` | `np.ndarray` | tuple of `np.ndarray` |
+
+- Series names follow pandas-ta conventions: `SMA_14`, `BBU_20_2.0`, etc.
+- DataFrame columns for multi-output: `BBU_20_2.0`, `BBM_20_2.0`, `BBL_20_2.0`.
+
+### 6.5 Concrete Python wrapper example
+
+```python
+# indicators.py (excerpt)
+import numpy as np
+import pandas as pd
+from quantalib._bridge import _lib, _check
+
+def sma(close, length=None, offset=None, **kwargs):
+ """Simple Moving Average."""
+ length = int(length) if length else 10
+ offset = int(offset) if offset else 0
+
+ # Extract numpy array
+ index = None
+ if isinstance(close, pd.Series):
+ index = close.index
+ close = close.to_numpy(dtype=np.float64, copy=False)
+ close = np.ascontiguousarray(close, dtype=np.float64)
+
+ n = len(close)
+ out = np.empty(n, dtype=np.float64)
+ _check(_lib.qtl_sma(
+ close.ctypes.data_as(c_double_p), n,
+ out.ctypes.data_as(c_double_p), length
+ ))
+
+ if offset:
+ out = np.roll(out, offset)
+ out[:offset] = np.nan
+
+ if index is not None:
+ result = pd.Series(out, index=index, name=f"SMA_{length}")
+ result.category = "trend"
+ return result
+ return out
+```
+
+### 6.6 NaN / warmup behavior
+
+- Warmup slots are filled with `NaN` by the C# `Batch` methods.
+- This matches pandas-ta's convention for most indicators.
+- Known deltas from pandas-ta warmup lengths are documented in the
+ compatibility table in `README.md`.
+
+### 6.7 pandas fallback policy
+
+When pandas is not installed:
+
+- Functions accept and return `np.ndarray` only.
+- `pd.Series` / `pd.DataFrame` input raises `ImportError` with message
+ `"pandas required for Series/DataFrame input"`.
+- `numpy` is a hard dependency; `pandas` is an optional extra.

+
+## 7) Build and packaging
+
+### 7.1 .NET project (`python.csproj`)
+
+```xml
+
+
+ net10.0
+ Library
+ true
+ quantalib
+ true
+ true
+ false
+
+
+
+
+
+
+
+
+```
+
+### 7.2 Local build props (`Directory.Build.props`)
+
+```xml
+
+
+ true
+ Speed
+ false
+ none
+
+
+```
+
+### 7.3 Publish script (`publish.ps1`)
+
+Requirements:
+
+- Publish for RIDs: `win-x64`, `linux-x64`, `osx-arm64`, `osx-x64`
+- Clean target directory before each publish
+- Verify expected artifact exists per RID (`.dll`, `.so`, `.dylib`)
+- Copy artifact into `quantalib/native//`
+- Exit non-zero on any missing artifact
+
+### 7.4 Python packaging (`pyproject.toml`)
+
+```toml
+[build-system]
+requires = ["hatchling"]
+build-backend = "hatchling.build"
+
+[project]
+name = "quantalib"
+version = "0.1.0"
+description = "High-performance technical analysis via QuanTAlib NativeAOT"
+requires-python = ">=3.10"
+dependencies = ["numpy>=1.24"]
+
+[project.optional-dependencies]
+pandas = ["pandas>=1.5"]
+dev = ["pytest", "pandas>=1.5"]
+
+[tool.hatch.build.targets.wheel]
+packages = ["quantalib"]
+```
+
+### 7.5 NativeAOT considerations
+
+- **Trimming:** NativeAOT trims unreachable code. All `Batch` methods are
+ reachable via explicit calls in `Exports.cs`, so no `rd.xml` needed.
+- **Reflection:** QuanTAlib indicators do not use reflection in `Batch` paths.
+- **SIMD:** NativeAOT preserves hardware intrinsics. `Avx2.IsSupported` works
+ at runtime in the compiled native binary.
+- **Startup:** NativeAOT has near-zero startup overhead. No JIT warmup.

+## 9) Compatibility strategy with pandas-ta
+
+### 9.1 Compatibility levels
+
+| Level | Description |
+|-------|-------------|
+| **L1** | Signature-compatible: same parameter names and defaults |
+| **L2** | Return-compatible: same return container shape and type |
+| **L3** | Behavior-compatible: matching warmup NaN count, naming, core semantics |
+
+### 9.2 pandas-ta overlap indicators
+
+These indicators exist in both pandas-ta and QuanTAlib. All target L2 minimum,
+L3 where QuanTAlib's algorithm matches:
+
+**Trend:** SMA, EMA, DEMA, TEMA, HMA, WMA, KAMA, FWMA, T3, TRIMA, ALMA, LSMA,
+SINEMA, VIDYA, ZLEMA, FRAMA, HWMA
+
+**Momentum:** RSI, ROC, MOM, CMO, MACD, PPO, TSI, RSX
+
+**Oscillators:** STOCH, STOCHF, STOCHRSI, WILLR, AO, APO, TRIX, FISHER, DPO,
+ULTOSC, KDJ, QQE, SQUEEZE, STC, RVGI
+
+**Volatility:** ATR, TR, BBANDS, BBW, MASSI, UI, EWMA (realized vol)
+
+**Volume:** OBV, ADL, ADOSC, CMF, MFI, NVI, PVI, PVT, VWAP, VWMA, EFI, KVO
+
+**Statistics:** ZSCORE, VARIANCE, STDDEV, SKEW, KURTOSIS, MEDIAN, ENTROPY,
+LINREG
+
+### 9.3 Known deltas
+
+- pandas-ta uses `talib=True` to delegate to TA-Lib C library; quantalib uses
+ its own C# implementations.
+- Warmup NaN counts may differ for recursive indicators (EMA, RSI) due to
+ different convergence thresholds.
+- `offset` parameter: quantalib supports it via `np.roll` in the Python layer.
+- `fillna`/`fill_method` kwargs: supported in Python layer, not in native.
+
+---
+
+## 10) Testing protocol
+
+### 10.1 Native ABI tests (C# xUnit in lib project)
+
+- Status-code contract tests for all exports
+- Null pointer, zero length, negative period → correct error codes
+- Known golden values vs managed `Batch` calls
+
+### 10.2 Python tests (pytest)
+
+| Suite | Description |
+|-------|-------------|
+| `test_smoke.py` | Import, load native lib, call SMA, check output is ndarray |
+| `test_shapes.py` | `len(output) == len(input)` for all single-output indicators |
+| `test_status_codes.py` | Null ptr, bad length, bad params raise correct exceptions |
+| `test_golden.py` | Compare outputs vs known golden values from managed QuanTAlib |
+| `test_compat.py` | pandas-ta parity for overlap indicators (Series/DataFrame) |
+
+### 10.3 Performance tests
+
+Track per-indicator:
+
+- Python wrapper overhead (µs per call for 10k bars)
+- Throughput (rows/sec)
+- Compare vs pandas-ta for overlap indicators
+
+Acceptance (initial baseline):
+
+- Median wrapper overhead does not exceed pandas-ta by more than 20% on overlap indicators where algorithms are directly comparable.
+- No unbounded memory growth across repeated runs.
+- Performance report is produced per release candidate and checked into CI artifacts.
+
+---
+
+## 11) CI and release
+
+### 11.1 Build matrix
+
+| RID | Runner | Artifact |
+|-----|--------|----------|
+| `win-x64` | `windows-latest` | `quantalib.dll` |
+| `linux-x64` | `ubuntu-latest` | `quantalib.so` |
+| `osx-arm64` | `macos-14` | `quantalib.dylib` |
+| `osx-x64` | `macos-13` | `quantalib.dylib` |
+
+### 11.2 Pipeline stages
+
+1. `dotnet publish -r -c Release` per RID
+2. Stage artifacts into `quantalib/native//`
+3. `python -m pytest tests/` per platform
+4. Build wheel with `python -m build`
+5. Upload to PyPI (manual trigger for releases)
+
+### 11.3 Release checklist
+
+- [ ] All RID artifacts present and loadable
+- [ ] All pytest suites pass on all platforms
+- [ ] Performance benchmark logged (no regressions)
+- [ ] `CHANGELOG.md` updated
+- [ ] Version bumped in `pyproject.toml`
+
+---
+
+## 12) Risk register
+
+| # | Risk | Impact | Mitigation |
+|---|------|--------|------------|
+| 1 | ABI breakage on update | High | Versioned symbols (`qtl_*`) + ABI contract tests |
+| 2 | NativeAOT trims used code | High | Explicit calls in `Exports.cs` guarantee reachability |
+| 3 | Platform loader failures | Medium | Explicit package-path loading + startup diagnostics |
+| 4 | Behavior drift vs pandas-ta | Medium | Compatibility suite + documented deltas |
+| 5 | Enum/array params over ABI | Medium | int/ptr mapping with documented contracts |
+| 6 | Large export surface (~290) | Medium | Code generation considered for `Exports.cs` if manual is too error-prone |
+| 7 | Cross-compilation failures | Medium | CI matrix catches per-platform issues early |
+| 8 | Thread safety | Low | `Batch` methods are stateless; no shared mutable state |
+
+---
+
+## 13) Review checklist
+
+- [ ] Naming accepted: PyPI/import/binary all `quantalib`
+- [ ] Versioned ABI prefix accepted (`qtl_*`)
+- [ ] Flat structure accepted (`Exports.cs`, `indicators.py`)
+- [ ] Status-code model accepted (0–4)
+- [ ] 9 ABI signature patterns accepted
+- [ ] Special parameter mappings accepted (enum→int, bool→int, array→ptr+len)
+- [ ] Full indicator catalog reviewed
+- [ ] Compatibility levels accepted (L1/L2/L3)
+- [ ] RID matrix accepted (4 platforms)
+- [ ] NaN/warmup policy accepted
+- [ ] Thread safety model accepted
+- [ ] CI pipeline accepted
+
+---
+
+## 14) Implementation order
+
+1. **Skeleton:** `python.csproj`, `Directory.Build.props`, package layout,
+ `_loader.py`, `_bridge.py` scaffolding, `pyproject.toml`
+2. **ABI layer:** `StatusCodes.cs`, `ArrayBridge.cs`, `Exports.cs` (all ~290)
+3. **Python layer:** `indicators.py` (all wrappers), `_compat.py` (aliases)
+4. **Tests:** `test_smoke.py`, `test_shapes.py`, `test_status_codes.py`,
+ `test_golden.py`, `test_compat.py`
+5. **Publish:** `publish.ps1`, CI workflow, wheel packaging
+6. **Docs:** `README.md` with full indicator list and compatibility table
+
+---
+
+## 15) Open decisions
+
+1. **Error mapping granularity:** `ValueError` for bad params vs separate
+ exception classes per status code (current spec uses separate classes).
+2. **Alpha overloads:** Export as `qtl_ema_alpha` or defer to v2?
+3. **Code generation:** Generate `Exports.cs` + `_bridge.py` + `indicators.py`
+ from a manifest file, or write manually?
+4. **Linux wheel tag:** `manylinux2014_x86_64` vs `manylinux_2_17_x86_64`?
+5. **Version sync:** Should `quantalib` Python version track QuanTAlib NuGet
+ version, or version independently?
+
+## 16) Review findings and prioritized refinements
+
+### High priority
+
+1. **Finalize ABI evolution policy**
+ - Keep `qtl_` immutable for v1 and reserve `qtl2_` for first break.
+2. **Adopt manifest-driven generation**
+ - Eliminate manual drift risk across native exports, ctypes bridge, and wrappers.
+3. **Clarify output validity on internal failures**
+ - Treat outputs as invalid on `QTL_ERR_INTERNAL`.
+
+### Medium priority
+
+4. **Lock pandas fallback behavior**
+ - NumPy-only mode should be deterministic and explicitly tested.
+5. **Define parity subset for L3**
+ - Freeze exact Wave 1 L3 indicator list before coding starts.
+6. **Set measurable perf gates**
+ - Keep CI benchmarks with comparable overlap indicators and stable datasets.
+
+### Low priority
+
+7. **Catalog automation**
+ - Generate indicator catalog tables from manifest to avoid stale docs.
+8. **Release metadata policy**
+ - Define whether Python package version mirrors or decouples from NuGet version.

+# pandas-ta parity report — Batch 01 (10 indicators)
+
+Date: 2026-02-28
+Test file: `python/tests/test_pandas_ta_parity_batch_01.py`
+Command: `python -m pytest python/tests/test_pandas_ta_parity_batch_01.py -q`
+
+## Summary
+
+- Total tests: **10**
+- Passed: **6**
+- Failed: **4**
+- Duration: **0.47s**
+
+## Indicators in Batch 01
+
+1. `rsi_14` ✅
+2. `mom_10` ✅
+3. `cmo_14` ❌
+4. `apo_12_26` ❌
+5. `bias_26` ✅
+6. `cfo_14` ❌
+7. `dpo_20` ✅
+8. `trix_18` ❌
+9. `er_10` ✅
+10. `cti_12` ✅
+
+## Failure details
+
+### 1) `cmo_14`
+- Error: numeric mismatch in tail window
+- Max diff: `4.017e+01`
+- Tolerance: `1e-6`
+
+### 2) `apo_12_26`
+- Error: numeric mismatch in tail window
+- Max diff: `1.633e+00`
+- Tolerance: `1e-6`
+
+### 3) `cfo_14`
+- Error: numeric mismatch in tail window
+- Max diff: `8.166e-01`
+- Tolerance: `1e-6`
+
+### 4) `trix_18`
+- Error: shape mismatch during comparison
+- `quantalib`: shape `(10000,)`
+- `pandas-ta`: shape `(10000, 2)` (DataFrame with TRIX + signal)
+- Exception: broadcast error in finite-mask step
+
+## Notes
+
+- Batch-01 tests were created and executed as requested.
+- Current failures are due to:
+ - Known algorithmic differences (`cmo`, `apo`, `cfo`) and/or parameter semantics mismatch.
+ - Output-shape mismatch for `trix` (single-series vs multi-column DataFrame).
