# Good Indicator Guidelines
|
||||
|
||||
This document defines the strict standards for creating high-quality technical indicators in the QuanTAlib library. All new indicators MUST adhere to these rules to ensure consistency, performance, and reliability.
|
||||
|
||||
## 1. Architecture & Design Principles
|
||||
|
||||
* **Zero Allocation:** The core calculation loop must not allocate memory on the heap. Use `stackalloc`, `Span<T>`, and pinned memory where possible.
|
||||
* **O(1) Complexity:** Streaming updates must be O(1) whenever mathematically possible. Use running sums/products or circular buffers to avoid re-iterating over history.
|
||||
* **Dual API:** Provide both a stateful object-oriented API (`Update`) and a stateless static vector API (`Calculate`).
|
||||
* **Bar Correction:** Support intra-bar updates via the `isNew` parameter. The indicator must be able to rollback the last update and apply a new value for the same timestamp.
|
||||
* **Robustness:** Handle `NaN` and `Infinity` gracefully using last-valid-value substitution. Never propagate invalid values.
|
||||
* **Reactive:** Implement `ITValuePublisher` to support event-driven architectures.
|
||||
|
||||
## 2. File Structure
|
||||
|
||||
Each indicator resides in its own directory such as `lib/trends/`, `lib/indicators/`, or `lib/oscillators/`.
|
||||
|
||||
**Directory:** `lib/[category]/[name]/`
|
||||
|
||||
| File | Purpose | Naming Convention |
|
||||
|------|---------|-------------------|
|
||||
| **Source** | Main implementation | `[Name].cs` (e.g., `Sma.cs`) |
|
||||
| **Tests** | Unit tests | `[Name].Tests.cs` |
|
||||
| **Validation** | Cross-library validation | `[Name].Validation.Tests.cs` |
|
||||
| **Docs** | User documentation | `[Name].md` |
|
||||
| **Quantower** | Quantower adapter | `[Name].Quantower.cs` |
|
||||
|
||||
## 3. Implementation Rules (`[Name].cs`)
|
||||
|
||||
### Class Definition
|
||||
|
||||
* **Namespace:** `QuanTAlib`
|
||||
* **Attributes:** `[SkipLocalsInit]` for performance.
|
||||
* **Modifiers:** `public sealed class`
|
||||
* **Interface:** Implements `ITValuePublisher`
|
||||
|
||||
### State Management
|
||||
|
||||
* Use `RingBuffer` for sliding window data.
|
||||
* Maintain separate state variables for the *current* calculation (`_sum`, `_lastVal`) and the *previous* valid state (`_p_sum`, `_p_lastVal`) to support `isNew=false` updates.
|
||||
* **Resync:** Implement a periodic full recalculation (e.g., every 1000 ticks) to prevent floating-point drift in running sums.
|
||||
|
||||
### Constructor
|
||||
|
||||
* Validate all parameters (throw `ArgumentException` for invalid values).
|
||||
* Initialize `Name` property (e.g., `$"Sma({period})"`);
|
||||
* Support chaining: `public [Name](ITValuePublisher source, ...)`
|
||||
|
||||
### Update Method
|
||||
|
||||
* **Signature:** `public TValue Update(TValue input, bool isNew = true)`
|
||||
* **Attribute:** `[MethodImpl(MethodImplOptions.AggressiveInlining)]`
|
||||
* **Logic:**
|
||||
1. **Input Validation:** Check `double.IsFinite`. If not, use `_lastValidValue`.
|
||||
2. **State Management:**
|
||||
* If `isNew=true`: Save current state to `_p_*` variables, then update.
|
||||
* If `isNew=false`: Restore state from `_p_*` variables, then update.
|
||||
3. **Calculation:** Perform the math.
|
||||
4. **Publish:** Update `Last` property, invoke `Pub` event, return `Last`.
|
||||
|
||||
### Update Method (TSeries)
|
||||
|
||||
* **Signature:** `public TSeries Update(TSeries source)`
|
||||
* **Placement:** Must be adjacent to the `Update(TValue)` method.
|
||||
* **Logic:**
|
||||
1. Create output series.
|
||||
2. Call static `Calculate(Span)` for performance.
|
||||
3. Restore internal state by replaying the last `Period` bars.
|
||||
|
||||
### Static Calculate (TSeries)
|
||||
|
||||
* Create a new instance of the indicator.
|
||||
* Iterate through the source series.
|
||||
* Return the resulting `TSeries`.
|
||||
|
||||
### Static Calculate (Span) - **Critical for Performance**
|
||||
|
||||
* **Signature:** `public static void Calculate(ReadOnlySpan<double> source, Span<double> output, ...)`
|
||||
* **Attribute:** `[MethodImpl(MethodImplOptions.AggressiveInlining)]`
|
||||
* **Optimization:**
|
||||
|
||||
* Check for SIMD support (`Avx2.IsSupported`).
|
||||
* Use `stackalloc` for small buffers (threshold ~256).
|
||||
* Implement a scalar fallback path that handles `NaN` safely.
|
||||
* Implement a SIMD path for large, clean datasets (optional but recommended for simple averages).
|
||||
|
||||
## 4. Testing Standards
|
||||
|
||||
### Unit Tests (`[Name].Tests.cs`)
|
||||
|
||||
* **Framework:** xUnit
|
||||
* **Coverage:**
|
||||
|
||||
* Constructor validation (invalid params).
|
||||
* Basic calculation correctness (compare against manual calc).
|
||||
* `isNew=true` vs `isNew=false` behavior (bar correction).
|
||||
* `Reset()` functionality.
|
||||
* `IsHot` property behavior.
|
||||
* `NaN` / `Infinity` handling (must not crash, must return finite values).
|
||||
* Consistency between Object API, Static TSeries API, and Static Span API.
|
||||
* Edge cases: Period=1, empty input, single input.
|
||||
|
||||
### Validation Tests (`[Name].Validation.Tests.cs`)
|
||||
|
||||
* **Purpose:** Verify accuracy against established libraries (Skender, TA-Lib, Tulip).
|
||||
* **Data:** Use `GBM` (Geometric Brownian Motion) to generate realistic test data.
|
||||
* **Scenarios:**
|
||||
|
||||
* Batch processing.
|
||||
* Streaming processing.
|
||||
* Span/Vector processing.
|
||||
|
||||
* **Tolerance:** Typically `1e-6` or `1e-9` depending on the algorithm.
|
||||
|
||||
## 5. Documentation Standards (`[Name].md`)
|
||||
|
||||
Follow the standard template and ensure strict adherence to Markdownlint rules, specifically:
|
||||
|
||||
* **MD030:** Ensure exactly one space after list markers (e.g., `* Item`, not `*Item` or `* Item`).
|
||||
* **MD032:** Ensure lists are surrounded by blank lines (one blank line before the first item and one after the last item).
|
||||
|
||||
Template structure:
|
||||
|
||||
1. **Title & Overview:** What is it? What does it do?
|
||||
2. **Core Concepts:** Key features (e.g., equal weighting, noise reduction).
|
||||
3. **Parameters:** Table of constructor parameters.
|
||||
4. **Formula:** LaTeX formatted math ($$...$$).
|
||||
5. **C# Implementation:** Code examples for:
|
||||
* Standard usage.
|
||||
* Span API (high performance).
|
||||
* Bar correction (`isNew`).
|
||||
* Eventing.
|
||||
6. **Interpretation:** How to use it in trading.
|
||||
7. **References:** Books or papers.
|
||||
|
||||
## 6. Performance Guidelines
|
||||
|
||||
* **Inlining:** Use `[MethodImpl(MethodImplOptions.AggressiveInlining)]` on all hot path methods (`Update`, `Calculate`).
|
||||
* **Locals Init:** Use `[SkipLocalsInit]` on the class to skip zero-initialization of locals.
|
||||
* **Loops:** Prefer `for` loops over `foreach` for arrays/spans.
|
||||
* **Math:** Use `System.Math` or `System.Numerics`. Avoid LINQ in hot paths.
|
||||
* **Memory:** **NEVER** use `new` inside the `Update` method. Pre-allocate everything in the constructor.
|
||||
|
||||

# ALMA: Arnaud Legoux Moving Average
|
||||
|
||||
## Overview and Purpose
|
||||
|
||||
The Arnaud Legoux Moving Average (ALMA) is a technical indicator that attempts to bridge the gap between responsiveness and smoothness. It uses a Gaussian distribution to determine the weights of the moving average, allowing the user to shift the peak of the weight distribution (offset) and control the width of the distribution (sigma).
|
||||
|
||||
ALMA is designed to reduce lag while maintaining smoothness, making it superior to traditional moving averages like SMA or EMA in many trend-following applications.
|
||||
|
||||
## Core Concepts
|
||||
|
||||
* **Gaussian Weighting:** Weights are distributed according to a bell curve.
|
||||
* **Offset Control:** Allows shifting the focus of the average. An offset of 0.5 is a symmetric filter (like SMA/WMA), while an offset closer to 1.0 makes it more responsive to recent prices.
|
||||
* **Sigma Control:** Controls the "sharpness" of the filter. Higher sigma values include more data points in the calculation, making it smoother but potentially introducing more lag.
|
||||
|
||||
## Parameters
|
||||
|
||||
| Parameter | Default | Description |
|
||||
|-----------|---------|-------------|
|
||||
| Period | 9 | The window size for the moving average. |
|
||||
| Offset | 0.85 | The center of the Gaussian distribution (0.0 to 1.0). |
|
||||
| Sigma | 6.0 | The standard deviation of the Gaussian distribution. |
|
||||
|
||||
## Formula
|
||||
|
||||
The weight for the $i$-th element in the window (where $i=0$ is the oldest) is calculated as:
|
||||
|
||||
$$W_i = \exp\left(-\frac{(i - \text{offset\_idx})^2}{2\sigma_{idx}^2}\right)$$
|
||||
|
||||
Where:
|
||||
|
||||
* $\text{offset\_idx} = \lfloor \text{Period} \times \text{Offset} \rfloor$
|
||||
* $\sigma_{idx} = \text{Period} / \text{Sigma}$
|
||||
|
||||
The ALMA value is the weighted sum:
|
||||
|
||||
$$ALMA = \frac{\sum_{i=0}^{n-1} P_i \times W_i}{\sum_{i=0}^{n-1} W_i}$$
|
||||
|
||||
## C# Implementation
|
||||
|
||||
### Standard Usage
|
||||
|
||||
```csharp
|
||||
using QuanTAlib;
|
||||
|
||||
// Initialize with period 9, offset 0.85, sigma 6
|
||||
var alma = new Alma(9, offset: 0.85, sigma: 6.0);
|
||||
|
||||
// Update with new value
|
||||
TValue result = alma.Update(new TValue(time, price));
|
||||
Console.WriteLine($"ALMA: {result.Value}");
|
||||
```
|
||||
|
||||
### Zero-Allocation Span API
|
||||
|
||||
```csharp
|
||||
double[] prices = ...;
|
||||
double[] output = new double[prices.Length];
|
||||
|
||||
// Calculate ALMA for the entire array
|
||||
Alma.Calculate(prices.AsSpan(), output.AsSpan(), period: 9, offset: 0.85, sigma: 6.0);
|
||||
```
|
||||
|
||||
### Bar Correction
|
||||
|
||||
```csharp
|
||||
var alma = new Alma(9);
|
||||
|
||||
// Update with initial tick
|
||||
alma.Update(new TValue(time, 100), isNew: true);
|
||||
|
||||
// Update with correction (same bar)
|
||||
alma.Update(new TValue(time, 101), isNew: false);
|
||||
```
|
||||
|
||||
## Interpretation
|
||||
|
||||
* **Trend Following:** Like other moving averages, ALMA helps identify the trend direction.
|
||||
* **Crossovers:** Price crossing ALMA or two ALMAs crossing each other can signal trend changes.
|
||||
* **Support/Resistance:** ALMA often acts as dynamic support/resistance.

# KAMA: Kaufman's Adaptive Moving Average
|
||||
|
||||
## Overview and Purpose
|
||||
|
||||
Kaufman's Adaptive Moving Average (KAMA) is an intelligent technical indicator that automatically adjusts its sensitivity based on market conditions. Developed by Perry Kaufman, KAMA solves the fundamental problem of traditional moving averages: their inability to adapt to changing market volatility.
|
||||
|
||||
KAMA becomes more responsive during trending markets (high efficiency) and more stable during sideways or choppy conditions (low efficiency). This self-adjusting behavior makes it valuable for traders who need a single moving average that can effectively handle different market environments without manual parameter changes.
|
||||
|
||||
## Core Concepts
|
||||
|
||||
* **Efficiency Ratio (ER):** Measures the directional movement relative to volatility.
|
||||
* **Market Adaptation:** Automatically adjusts sensitivity based on current price behavior.
|
||||
* **Non-linear Response:** Uses a squared smoothing constant to emphasize differences between trending and non-trending states.
|
||||
|
||||
## Parameters
|
||||
|
||||
| Parameter | Default | Description |
|
||||
|-----------|---------|-------------|
|
||||
| Period | 10 | The lookback window for the Efficiency Ratio. |
|
||||
| Fast Period | 2 | The effective EMA period when the market is trending (ER = 1). |
|
||||
| Slow Period | 30 | The effective EMA period when the market is choppy (ER = 0). |
|
||||
|
||||
## Formula
|
||||
|
||||
1. **Efficiency Ratio (ER):**
|
||||
$$ER = \frac{\text{Change}}{\text{Volatility}}$$
|
||||
$$\text{Change} = |P_t - P_{t-n}|$$
|
||||
$$\text{Volatility} = \sum_{i=0}^{n-1} |P_{t-i} - P_{t-i-1}|$$
|
||||
|
||||
2. **Smoothing Constant (SC):**
|
||||
$$SC = \left(ER \times (\alpha_{fast} - \alpha_{slow}) + \alpha_{slow}\right)^2$$
|
||||
$$\alpha_{fast} = \frac{2}{\text{FastPeriod} + 1}$$
|
||||
$$\alpha_{slow} = \frac{2}{\text{SlowPeriod} + 1}$$
|
||||
|
||||
3. **KAMA:**
|
||||
$$KAMA_t = KAMA_{t-1} + SC \times (P_t - KAMA_{t-1})$$
|
||||
|
||||
## C# Implementation
|
||||
|
||||
### Standard Usage
|
||||
|
||||
```csharp
|
||||
using QuanTAlib;
|
||||
|
||||
// Initialize with period 10, fast 2, slow 30
|
||||
var kama = new Kama(10, fastPeriod: 2, slowPeriod: 30);
|
||||
|
||||
// Update with new value
|
||||
TValue result = kama.Update(new TValue(time, price));
|
||||
Console.WriteLine($"KAMA: {result.Value}");
|
||||
```
|
||||
|
||||
### Zero-Allocation Span API
|
||||
|
||||
```csharp
|
||||
double[] prices = ...;
|
||||
double[] output = new double[prices.Length];
|
||||
|
||||
// Calculate KAMA for the entire array
|
||||
Kama.Calculate(prices.AsSpan(), output.AsSpan(), period: 10, fastPeriod: 2, slowPeriod: 30);
|
||||
```
|
||||
|
||||
### Bar Correction
|
||||
|
||||
```csharp
|
||||
var kama = new Kama(10);
|
||||
|
||||
// Update with initial tick
|
||||
kama.Update(new TValue(time, 100), isNew: true);
|
||||
|
||||
// Update with correction (same bar)
|
||||
kama.Update(new TValue(time, 101), isNew: false);
|
||||
```
|
||||
|
||||
## Interpretation
|
||||
|
||||
* **Trend Identification:** When price is consistently above KAMA, it indicates an uptrend. Below indicates a downtrend.
|
||||
* **Trend Strength:** A steep KAMA slope suggests a strong trend. A flat KAMA suggests consolidation.
|
||||
* **Support/Resistance:** KAMA often acts as dynamic support or resistance, especially during pullbacks in a trend.
|
||||
* **Filter:** KAMA filters out minor fluctuations during sideways markets while remaining responsive to genuine breakouts.
