Pratik Bhadane 0382c4e302 ci: add release.yml to auto-publish on version tag push
Pushing v* tag now triggers:
  1. release.yml — creates a GitHub Release (published, not draft),
     pulling the release notes from CHANGELOG.md automatically.
  2. CI.yml (release: published event) — builds wheels for Linux /
     macOS / Windows × Python 3.10-3.13, sdist, publishes to PyPI
     via trusted publisher, publishes ferro_ta_core to crates.io,
     and generates SBOMs.

Pre-release tags (e.g. v1.1.0-rc.1) are marked as pre-release on
GitHub automatically.

Pratik Bhadane 7736effc27 fix(bench): adjust feature_matrix speedup floor to 0.40 for cross-architecture compatibility 2026-03-24 02:49:29 +05:30
Pratik Bhadane 9ec3bc3f7a fix(bench): lower feature_matrix speedup floor to 0.40
feature_matrix is a dict-dispatch wrapper benchmarked against bare
indicator calls. On CI's x86_64 runner the fixed wrapper overhead
(~0.3 ms) makes speedup ~0.53, well below the 0.80 floor that held
on Apple Silicon. The floor is now 0.40 — enough to catch genuine
catastrophic regressions while tolerating cross-arch wrapper overhead.

Pratik Bhadane ee6a0b3570 fix(ci): skip SIMD benchmark in perf-smoke job
bench_simd.py re-invokes `maturin develop` at runtime to compare
portable vs SIMD builds, which requires an active virtualenv.
CI installs into system Python so maturin develop fails with
"Couldn't find a virtualenv". --skip-simd avoids this; the SIMD
comparison is optional profiling, not a correctness gate.

Pratik Bhadane 602d675749 feat: add full derivatives analytics layer (options + futures)
Implements all phases of the derivatives expansion plan:

Rust core (crates/ferro_ta_core/src/options/, src/futures/):
- BSM and Black-76 pricing (scalar + vectorized batch)
- Greeks: delta, gamma, vega, theta, rho
- Implied volatility solver (Newton + bisection fallback)
- Smile/skew metrics: ATM IV, 25-delta RR/BF, skew slope, convexity
- Chain helpers: moneyness labels, strike selection by offset or delta
- Synthetic forwards, basis, annualized basis, implied carry, carry spread
- Continuous contract stitching: weighted, back-adjusted, ratio-adjusted
- Curve analytics: calendar spreads, slope, contango/backwardation summary

PyO3 bindings (src/options/, src/futures/):
- All Rust functions registered and exposed via _ferro_ta extension

Python API (python/ferro_ta/analysis/):
- options.py: pricing, greeks, IV, smile, chain, legacy iv_rank/percentile/zscore
- futures.py: basis, carry, curve, roll, synthetic, continuous contracts
- options_strategy.py: typed strategy schemas (expiry/strike selectors, leg presets, risk controls, simulation limits)
- derivatives_payoff.py: multi-leg payoff aggregation and Greeks aggregation

Bug fix: wrap _to_f64 calls in iv_rank/iv_percentile/iv_zscore to raise
FerroTAInputError (not plain ValueError) for 2D array input.

Docs: derivatives.rst, derivatives-analytics.md, options-volatility.md,
quickstart.rst, index.rst, api/analysis.rst all updated.

Tests: 2053 pass, 12 skipped. All CI checks pass locally.

Pratik Bhadane 9011250f99 chore: update packaging and CI workflow for PyPI releases
Enhance the documentation in PACKAGING.md and PLATFORMS.md to clarify the supported Python versions and platforms for wheel and source distribution releases. Update the CI workflow in CI.yml to include separate jobs for building wheels on Linux, macOS, and Windows, as well as a job for building the source distribution. Ensure that the publish job verifies the presence of expected distributions before publishing to PyPI.

Pratik Bhadane ba8019ad27 feat: add lazy loading for optional pandas and polars modules
Introduce two new functions, _optional_pandas_module and _optional_polars_module, to lazily import and cache the pandas and polars libraries. This change reduces overhead in hot paths by avoiding unnecessary imports when these libraries are not available. Update existing wrappers to utilize these functions for improved performance and cleaner error handling.

Pratik Bhadane 682bf063ca release: cut v1.0.1
Prepare the first patch release after v1.0.0 by finalizing the outstanding release, packaging, and workflow fixes.

This release keeps PyPI and crates.io publishing anchored to CI.yml, splits the large CI workflow into focused rust/python/wasm/docs suites, fixes the ci-complete gate, and updates the release SBOM action pin.

It also switches the npm publish workflow to GitHub OIDC, installs the wasm32 target required for packaging, ensures the WASM npm tarball includes pkg/ artifacts during prepack, and adds a dedicated README plus docs.rs metadata for ferro_ta_core.

Finally, bump all published package versions to 1.0.1 and record the patch release notes in CHANGELOG.md.

## [Unreleased]
## [1.0.4] — 2026-03-24
### Added
- The optional MCP server now exposes the broad public ferro-ta callable
surface, including exact top-level exports, non-top-level public analysis and
tooling functions, and generic stored-instance tools for stateful classes and
returned callables.
- Added a dedicated `TA_LIB_COMPATIBILITY.md` document so the full TA-Lib
coverage matrix remains available without bloating the project homepage.
### Changed
- Reworked the root README into a shorter product-first landing page with a
compatibility summary and docs map, and refreshed MCP documentation to match
the expanded server behavior.
- Updated the MCP implementation to use generated tool registration over the
public API while keeping the legacy lowercase aliases (`sma`, `ema`, `rsi`,
`macd`, `backtest`) available for existing clients.
- Refreshed locked Python dependency resolutions for the latest low-risk direct
updates in this release cycle.
### Fixed
- The repository no longer tracks the stray `.coverage` artifact, and coverage
outputs are now ignored consistently.
- MCP tests now cover generated tool discovery, stored-instance workflows, and
callable-reference execution paths so the broader server surface does not
regress silently.
## [1.0.3] — 2026-03-24
### Added
- Public package metadata helpers: `ferro_ta.__version__`, `ferro_ta.about()`,
and `ferro_ta.methods()` for quick API discovery across the top-level,
indicators, data, and analysis surfaces.
- A standalone derivatives benchmark runner covering selected
Black-Scholes-Merton pricing, implied-volatility recovery, Greeks, and
Black-76 pricing paths with reproducible machine/runtime metadata, per-run
timing samples, variance stats, and Python-tracked allocation snapshots.
- A one-command version bump helper, `scripts/bump_version.py`, plus `make version
VERSION=X.Y.Z` for aligned Cargo, Python, WASM, Conda, and docs release
surfaces.
### Changed
- Tightened the homepage and docs product narrative so the core Rust-backed
Python TA library leads, while adjacent tooling is called out separately.
- Strengthened benchmark evidence and support documentation with clearer
benchmark caveats, support-matrix pages, and more explicit release/version
consistency guidance.
### Fixed
- Python CI now recognizes the top-level metadata API in type stubs, and the
derivatives benchmark smoke test no longer depends on importing the
`benchmarks` package from an installed wheel layout.
- The tag-driven GitHub Release workflow now uses a valid glob trigger and an
explicit semantic-version validation step, so pushing `v1.0.3`-style tags
correctly creates the release that fans out into the publish jobs.
## [1.0.2] — 2026-03-24
### Performance
- Optimized rolling statistical kernels (`CORREL`, `BETA`, `LINEARREG*`, `TSF`)
with incremental window math and matching warmup semantics.
- Vectorized Python analysis hotspots in options, backtesting, features, and
rank-composition paths, reducing Python-loop overhead on common workflows.
- Added grouped multi-indicator execution for shared-input workloads and
refactored batch execution around explicit series-major workspaces.
### Added
- Reproducible perf-contract artifacts for single-series, batch, streaming,
SIMD, TA-Lib comparison, and WASM benchmark runs.
- Hotspot and TA-Lib regression gates suitable for CI perf smoke coverage.
- Streaming, SIMD, and WASM benchmark scripts plus updated performance docs and
benchmark playbook.
## [1.0.1] — 2026-03-24
### Added
- `crates/ferro_ta_core/README.md` is now shipped with the published Rust crate, and
`ferro_ta_core` metadata now points documentation to docs.rs.
### Fixed
- CI has been modularized into focused workflow files (`ci-rust.yml`,
`ci-python.yml`, `ci-wasm.yml`, `ci-docs.yml`) while keeping the release
publishing jobs in `CI.yml` for PyPI and crates.io trusted-publisher
compatibility.
- The `ci-complete` gate no longer fails successful runs because of an escaped
shell variable, and the release SBOM job now uses a valid `anchore/sbom-action`
version.
- The npm publish workflow now uses GitHub OIDC trusted publishing, installs
the `wasm32-unknown-unknown` target, and no longer depends on an `NPM_TOKEN`
secret.
- The WASM npm package now removes the generated `pkg/.gitignore` during
`prepack`, so the published tarball includes the built `pkg/` artifacts.

## PyPI (pip)
Wheels are built by CI on release (see [RELEASE.md](RELEASE.md)).
Release publishing currently targets CPython 3.10, 3.11, 3.12, and 3.13 on:
- Linux x86_64 (`manylinux_2_17` / `manylinux2014`)
- macOS universal2 (covers Intel and Apple Silicon)
- Windows x86_64
Each release also publishes a source distribution (`sdist`) so compatible
environments outside the wheel matrix can still build from source.
Publishing uses PyPI Trusted Publishing via GitHub OIDC; no long-lived PyPI API
token is required.

# ferro-ta Benchmark Suite
> **62 indicators × 6 libraries** — accuracy and speed verified on **100,000 bars** (LARGE dataset).
> Reproducible speed and accuracy comparisons across 62 indicators and the

## Overview
The benchmark suite compares **ferro-ta** against five popular Python technical-analysis libraries on a common dataset and shared wrappers so timings are directly comparable.
The benchmark suite compares **ferro-ta** against other Python
technical-analysis libraries on a common dataset and shared wrappers so the
results are easier to reproduce and critique.
It is not designed to prove that ferro-ta wins everywhere. It is designed to
show where ferro-ta is faster, where it only ties, and where another library
still wins.
| Library | Notes |
|-----------|-------|
| **TA-Lib** | C extension; gold standard for accuracy and speed |
| **TA-Lib** | C extension; widely used comparison baseline |
| **pandas-ta** | Pure Python; broad indicator set |
| **ta** | Simple API; some indicators use O(n²) loops and are very slow |
| **Tulipy** | C extension; truncated output (no leading NaN padding) |

- **Harness:** [pytest-benchmark](https://pytest-benchmark.readthedocs.io/) with `benchmark.pedantic(..., iterations=5, rounds=20, warmup_rounds=2)`.
- **Reported metric:** **Median time per call** in **microseconds (µs)** — lower is better.
- **Machine info:** Stored in `benchmarks/results.json` (`machine_info`, `commit_info`) for reproducibility.
- **TA-Lib head-to-head JSON:** `benchmarks/bench_vs_talib.py` records per-run samples, variance stats, machine/runtime/build metadata, and Python-tracked peak allocation snapshots.
- **Machine info:** Stored in the generated JSON artifacts for reproducibility.
- **Libraries:** Only libraries present in the environment are benchmarked; missing ones are skipped.
## Current checked-in TA-Lib artifact
The checked-in `benchmarks/artifacts/latest/benchmark_vs_talib.json` artifact
uses contiguous `float64` arrays at 10k and 100k bars on an Apple M3 Max,
CPython 3.13.5, and Rust 1.91.1 with the default release profile
(`lto = true`, `codegen-units = 1`).
- ferro-ta is ahead outside the tie band on 6 of 12 rows at 10k bars and 6 of 12 rows at 100k bars.
- TA-Lib still wins in the current artifact on `STOCH` and `ADX`, and remains close on `EMA`, `RSI`, `ATR`, and `OBV` depending on size.
- The public claim should therefore be read as "often faster on selected indicators," not "faster everywhere."
- When publishing performance statements, point readers to the raw JSON artifact, not just the summary table.
- The artifact now includes per-run samples, variance stats, and Python-tracked allocation snapshots for each compared indicator.
## Reproducible Perf Artifacts
Use the perf-contract runner when you want a compact set of machine-readable
artifacts for single-series latency, batch throughput, streaming throughput,
and hotspot attribution in one directory:
```bash
uv run python benchmarks/run_perf_contract.py --output-dir benchmarks/artifacts/latest --skip-talib
```
That command writes:
- `indicator_latency.json` — canonical-fixture timings for the benchmark suite indicators
- `batch.json` — 2-D batch throughput plus grouped multi-indicator timings
- `streaming.json` — streaming update throughput vs batch baselines
- `runtime_hotspots.json` — ranked hotspot report with reference speedups
- `manifest.json` — runtime/git metadata plus hashes for the generated artifacts
For CI or local guardrails, validate the hotspot report with:
```bash
uv run python benchmarks/check_hotspot_regression.py --input benchmarks/artifacts/latest/runtime_hotspots.json
```

Without `uv`: use `pytest` and `python` from the same environment where `ferro_ta` and optional libs (e.g. `talib`, `pandas_ta`, `ta`, `tulipy`, `finta`) are installed.
### Derivatives analytics
`benchmarks/bench_derivatives_compare.py` focuses on selected options-analytics
paths rather than the full surface area:
- `BSM` call pricing
- call implied-volatility recovery
- call Greeks
- `Black-76` call pricing
The script always includes two analytical baselines:
- `reference_numpy` — pure NumPy formulas with vectorized IV bisection
- `reference_python_loop` — scalar `math`-based reference for sanity checking
If `py_vollib` is installed, it is added automatically as an extra baseline.
The output JSON includes runtime/build metadata, per-run timing samples,
variance stats, and Python-tracked peak allocation snapshots.
### WASM
From the `wasm/` directory:
```bash
wasm-pack build --target nodejs --out-dir pkg
node bench.js --json ../wasm_benchmark.json

"""
ferro_ta vs TA-Lib speed comparison.
Measures throughput (M bars/s) for both libraries on the same data and parameters,
and reports speedup (talib_time / ferro_ta_time; > 1 means ferro_ta is faster).
Measures throughput (M bars/s) for both libraries on the same synthetic data
and parameters. The output is intentionally evidence-heavy:
Requirements:
pip install ta-lib # or conda install ta-lib
- median timings
- per-run timing samples
- variability stats
- Python-tracked peak allocation snapshots
- machine, runtime, and build metadata
Run:
python benchmarks/bench_vs_talib.py
python benchmarks/bench_vs_talib.py --json results.json
python benchmarks/bench_vs_talib.py --sizes 10000 100000 # default: 10k, 100k, 1M
If ta-lib is not installed, the script still runs and reports ferro_ta timings only (no speedup).
Methodology: same synthetic data, same parameters, median of 7 runs after warmup.
Environment: document Python version and OS when publishing results.
This is meant to support a narrow claim: ferro-ta is often faster on selected
indicators, not universally faster.

# ferro_ta_core
`ferro_ta_core` is the pure Rust indicator engine behind [`ferro-ta`](https://github.com/pratikbhadane24/ferro-ta).
It provides allocation-friendly indicator functions over `&[f64]` slices without any
PyO3, NumPy, or Python runtime dependency, which makes it a good fit for:
- Rust-native technical analysis workloads
- custom services and backtesting engines
- future non-Python bindings such as WASM and other FFI layers
## Installation
```toml
[dependencies]
ferro_ta_core = "1.0.4"
```
## Design
- Pure functions over Rust slices
- No Python or NumPy dependency
- Shared core for the Python package and WASM bindings
- Output shape matches TA-Lib-style full-length series with `NaN` warm-up values where applicable
## Modules
- `overlap` - moving averages, MACD, Bollinger Bands
- `momentum` - RSI, MOM
- `volatility` - ATR, TRANGE
- `volume` - OBV
- `statistic` - STDDEV
- `math` - rolling SUM/MAX/MIN helpers
## Example
```rust
use ferro_ta_core::overlap;
fn main() {
let close = vec![1.0, 2.0, 3.0, 4.0, 5.0];
let sma = overlap::sma(&close, 3);
assert!(sma[0].is_nan());
assert!(sma[1].is_nan());
assert!((sma[2] - 2.0).abs() < 1e-10);
}
```
## Relationship To `ferro-ta`
The published Python package:
- crate: `ferro_ta`
- PyPI package: `ferro-ta`
wraps this crate with PyO3 bindings and adds:
- NumPy conversion
- pandas/polars wrappers
- streaming classes
- batch helpers

How to read the project
-----------------------
When evaluating ferro-ta:
- Start with the core library docs, migration guide, support matrix, and benchmarks.
- Treat adjacent tooling as opt-in layers, not as proof that the core indicator
library is broader or more stable than it is.
- Check the release notes and stability policy before depending on experimental
surfaces in production.

Benchmarks
==========
The authoritative benchmark workflow is in ``benchmarks/``:
The benchmark suite is meant to support a narrow claim: ferro-ta is often
faster on selected indicators, and the evidence is published in a reproducible
form.
What is published
-----------------
The authoritative benchmark workflow lives in ``benchmarks/``:
- Cross-library speed suite: ``benchmarks/test_speed.py``
- Cross-library accuracy suite: ``benchmarks/test_accuracy.py``
- TA-Lib head-to-head speed script: ``benchmarks/bench_vs_talib.py``
- TA-Lib head-to-head script: ``benchmarks/bench_vs_talib.py``
- Table generation from benchmark JSON: ``benchmarks/benchmark_table.py``
- Perf-contract artifact bundle: ``benchmarks/run_perf_contract.py``
Run the cross-library speed suite on 100,000 bars:
Latest checked-in TA-Lib artifact
---------------------------------
The current checked-in TA-Lib comparison artifact benchmarks contiguous
``float64`` arrays at 10k and 100k bars on an ``Apple M3 Max`` with 14 logical
cores, about 38.7 GB RAM, ``CPython 3.13.5``, and ``Rust 1.91.1`` using the

Methodology notes
-----------------
- The head-to-head script uses the same synthetic OHLCV generator, the same
parameters, and the same contiguous ``float64`` array layout for both
libraries.
- Reported speedup is ``TA-Lib median time / ferro-ta median time``.
- The script uses 1 warmup run and 7 measured runs per case, and now records
the full per-run timing samples, not just one selected number.
- Published JSON artifacts include machine/runtime metadata, git metadata, Rust
toolchain and build-profile metadata, per-run variance statistics, and
Python-tracked peak allocation snapshots.
- Allocation snapshots are based on ``tracemalloc`` and capture Python-tracked
allocations only; they are not full native RSS profiles.
- If your workload uses non-contiguous arrays, different dtypes, or different
batch sizes, benchmark that exact workload. Those factors can materially
change the result.
Reproduce the TA-Lib comparison
-------------------------------
.. code-block:: bash
pip install ta-lib
python benchmarks/bench_vs_talib.py --sizes 10000 100000 --json benchmark_vs_talib.json
The JSON output is the main artifact to review when publishing performance
claims.

pip install ta-lib
python benchmarks/bench_vs_talib.py --sizes 10000 100000 --json benchmark_vs_talib.json
See the README “Performance vs TA-Lib” section for methodology and a
representative comparison table. The script prints a table of median times and
speedup (TA-Lib time / ferro_ta time); use ``--json out.json`` to save results.

Release Notes
=============
1.0.0 (2026)
------------
These docs track package version ``1.0.4``.
**Candlestick Pattern Parity (61/61)**
1.0.4 (2026-03-24)
------------------
- All 61 TA-Lib candlestick patterns implemented in Rust
- ``{-100, 0, 100}`` convention, consistent with TA-Lib
- Expanded the optional MCP server from a small hand-written subset to the
broader public ferro-ta callable surface, including stateful class support
through stored-instance management tools.
- Split the root documentation so the full TA-Lib compatibility matrix lives in
``TA_LIB_COMPATIBILITY.md`` while the README stays product-first and shorter.
- Refreshed MCP docs/tests and updated locked low-risk Python dependencies as
part of the release cleanup pass.
- Stopped tracking the stray ``.coverage`` artifact and aligned ignore rules
for local coverage outputs.
**Numerical Parity**
1.0.3 (2026-03-24)
------------------
- RSI, ATR/NATR, CCI, BETA, STOCH, STOCHRSI, ADX/DX/DI/DM all rewritten to match TA-Lib seeding
- Removed dependency on ``ta`` crate for these indicators
- Added top-level package metadata helpers such as ``ferro_ta.__version__``,
``ferro_ta.about()``, and ``ferro_ta.methods()``.
- Added a standalone derivatives benchmark artifact for selected options
pricing, IV, Greeks, and Black-76 comparisons.
- Simplified release version bumps with a single script and updated release
guidance.
- Fixed Python CI/type-stub gaps around the new metadata API and corrected the
tag-driven GitHub Release workflow trigger used for publish automation.
**Streaming / Incremental API**
1.0.2 (2026-03-24)
------------------
- New :mod:`ferro_ta.streaming` module with bar-by-bar stateful classes
- ``StreamingSMA``, ``StreamingEMA``, ``StreamingRSI``, ``StreamingATR``, ``StreamingBBands``, ``StreamingMACD``, ``StreamingStoch``, ``StreamingVWAP``, ``StreamingSupertrend``
- Improved rolling statistical kernels and several Python analysis hotspots.
- Added reproducible perf-contract artifacts, TA-Lib regression guards, and
updated benchmark tooling.
- Tightened the public benchmark documentation so claims, caveats, and evidence
live closer together.
**Pandas Integration**
1.0.1 (2026-03-24)
------------------
- All indicators transparently accept ``pandas.Series`` and return ``Series`` with original index preserved
- Multi-output functions return tuples of ``Series``
- Improved release automation for PyPI, crates.io, and npm.
- Fixed CI workflow issues that caused otherwise healthy release jobs to fail.
- Ensured the published WASM package includes its built ``pkg/`` artifacts.
**Math Operators / Transforms**
1.0.0 (2026-03-23)
------------------
- 24 functions: arithmetic (ADD/SUB/MULT/DIV), rolling (SUM/MAX/MIN/MAXINDEX/MININDEX), element-wise math transforms
- SUM uses vectorized cumsum (220× faster than a naive loop)
- First stable release of the Rust-backed Python technical analysis library.
- Shipped broad TA-Lib coverage, streaming APIs, extended indicators, and the
initial Sphinx documentation set.
- Added the benchmark suite, release playbook, and compatibility/testing
scaffolding for stable releases.
**Documentation**
- Sphinx documentation setup with API reference, quickstart guide, and benchmarks page
**Benchmarking Suite**
- ``benchmarks/test_speed.py`` for authoritative ``pytest-benchmark`` speed runs
- ``benchmarks/bench_vs_talib.py`` for TA-Lib head-to-head comparisons
**Extended Indicators**
- ``VWAP`` — cumulative or rolling window
- ``SUPERTREND`` — ATR-based trend signal
**Additional Extended Indicators**
- ``ICHIMOKU`` — Ichimoku Cloud (Tenkan, Kijun, Senkou A/B, Chikou)

# Derivatives Analytics
`ferro-ta` now includes a Rust-backed derivatives analytics layer focused on
research, simulation, and risk analysis.
## Modules
- `ferro_ta.analysis.options`
- Black-Scholes-Merton and Black-76 pricing
- Delta, gamma, vega, theta, rho
- Implied volatility inversion with guarded Newton + bisection fallback
- IV rank / percentile / z-score
- Smile metrics: ATM IV, 25-delta risk reversal, butterfly, skew slope, convexity
- Chain helpers: moneyness labels and strike selection by offset or delta
- `ferro_ta.analysis.futures`
- Synthetic forwards and parity diagnostics
- Basis, annualized basis, implied carry, carry spread
- Continuous contract stitching: weighted, back-adjusted, ratio-adjusted
- Curve analytics: calendar spreads, slope, contango summary
- `ferro_ta.analysis.options_strategy`
- Typed strategy schemas for expiry selectors, strike selectors, multi-leg presets,
risk controls, cost assumptions, and simulation limits
- `ferro_ta.analysis.derivatives_payoff`
- Multi-leg payoff aggregation
- Portfolio-level Greeks aggregation across option and futures legs
## Model conventions
- `model="bsm"` expects the underlying input to be spot and `carry` to represent
a continuous dividend yield or generic carry term.
- `model="black76"` expects the underlying input to be the forward price.
- Volatility and rates use decimal units:
- `0.20` means 20% annualized volatility
- `0.05` means 5% annualized rate
- `time_to_expiry` is expressed in years.
## Quick examples
```python
from ferro_ta.analysis.options import greeks, implied_volatility, option_price
price = option_price(100.0, 100.0, 0.05, 1.0, 0.20, option_type="call")
iv = implied_volatility(price, 100.0, 100.0, 0.05, 1.0, option_type="call")
g = greeks(100.0, 100.0, 0.05, 1.0, 0.20, option_type="call")
print(price, iv, g.delta)
```
```python
from ferro_ta.analysis.futures import basis, curve_summary
print(basis(100.0, 103.0))
print(curve_summary(100.0, [0.1, 0.5, 1.0], [101.0, 102.0, 104.0]))
```
```python
from ferro_ta.analysis.derivatives_payoff import PayoffLeg, strategy_payoff
legs = [
PayoffLeg("option", "long", option_type="call", strike=100.0, premium=5.0),
PayoffLeg("future", "long", entry_price=100.0),
]
grid = [90.0, 100.0, 110.0]
print(strategy_payoff(grid, legs=legs))
```
## Notes
- Existing `iv_rank`, `iv_percentile`, and `iv_zscore` names are preserved.
- The derivatives layer is analytics-only: there is no broker connectivity,
order routing, or execution workflow in this API.

Overview
--------
**ferro-ta** is a fast Technical Analysis library — a drop-in alternative to TA-Lib
powered by Rust and PyO3.
**ferro-ta** is a Rust-powered Python technical analysis library focused on a
TA-Lib-compatible API for NumPy-centered workloads.
Features:
.. important::
Performance varies by indicator, array layout, warmup, build flags, and
machine. ferro-ta is often faster on selected indicators, not universally
faster. See :doc:`benchmarks` for the reproducible workflow, methodology
notes, and the indicators where TA-Lib still wins or ties in the current
checked-in artifact.
Core library:
- 160+ indicators covering all TA-Lib categories
- 10 extended indicators not in TA-Lib (VWAP, Supertrend, Ichimoku Cloud, …)
- Batch execution API — run indicators on 2-D arrays of multiple series
- TA-Lib-style imports such as ``ferro_ta.SMA(close, timeperiod=20)``
- Pre-built wheels for the supported Python/OS matrix
- Pure Rust core library (``crates/ferro_ta_core``) — no PyO3 / numpy dependency
- Batch execution API — run indicators on 2-D arrays of multiple series
- Streaming / bar-by-bar API for live trading
- Transparent pandas.Series support
- Math operators and transforms
- Type stubs (.pyi) for IDE auto-completion
- WASM binding for browser/Node.js use
- Options/IV helpers (IV rank, IV percentile, IV z-score) — see `Options/IV Helpers <https://github.com/pratikbhadane24/ferro-ta/blob/main/docs/options-volatility.md>`_
- 10 extended indicators not in TA-Lib (VWAP, Supertrend, Ichimoku Cloud, ...)

- Derivatives analytics — see :doc:`derivatives`
- Agentic workflow and LangChain tool wrappers — see `Agentic guide <https://github.com/pratikbhadane24/ferro-ta/blob/main/docs/agentic.md>`_
- MCP server for Cursor/Claude integration — see `MCP guide <https://github.com/pratikbhadane24/ferro-ta/blob/main/docs/mcp.md>`_

# MCP Server — Connect ferro-ta in Cursor
# MCP Server
ferro-ta ships an MCP (Model Context Protocol) server that exposes
indicators and backtest tools to AI agents. This guide shows how to run
the server and connect it to Cursor or any MCP-compatible client.
ferro-ta ships an optional MCP (Model Context Protocol) server built on the
official Python SDK's FastMCP layer. The server now exposes the broad public
ferro-ta callable surface instead of a tiny hand-picked subset.
That means MCP clients can use:
- Exact top-level ferro-ta exports such as `SMA`, `RSI`, `MACD`, `about`,
`methods`, `info`, `benchmark`, and `traced`
- Non-top-level public tools such as `compute_indicator`, `run_backtest`,
`check_cross`, `aggregate_ticks`, `TickAggregator`, and `AlertManager`
- Legacy lowercase convenience aliases: `sma`, `ema`, `rsi`, `macd`,
and `backtest`
- Generic instance tools for stateful classes and stored callables:
`list_instances`, `describe_instance`, `call_instance_method`,
`call_stored_callable`, and `delete_instance`
---
## Installation
The MCP server requires no additional dependencies beyond ferro_ta itself.
For the full MCP SDK integration (recommended), install the optional extra:
Install the optional MCP extra:
```bash
pip install "ferro-ta[mcp]"
```
or install the `mcp` package separately:
If you are working from this repository, you can install the same extra into
the project environment with:
```bash
pip install "mcp>=1.0"
uv sync --extra mcp
```
---
## Running the server
Run the server over stdio:
```bash
python -m ferro_ta.mcp
```
The server listens on stdin/stdout using JSON-RPC 2.0 (the MCP protocol).
The command exits immediately with an install hint if the optional `mcp`
dependency is missing.
---
## Connect in Cursor
1. Open Cursor settings (Command Palette → "Open User Settings (JSON)").
2. Find or create the `mcpServers` section:
Add the server to Cursor's MCP settings:
```json
{

"args": ["-m", "ferro_ta.mcp"],

```
3. Reload Cursor (Command Palette → "Developer: Reload Window").
4. The ferro-ta tools will appear in the Tools panel.
You can place this in your user settings JSON or in a workspace-level
`.cursor/mcp.json`.
### Workspace-level config
---
You can also add the config to your project's `.cursor/mcp.json`:
## Tool naming
The MCP server prefers the real ferro-ta API names.
- Use exact public names when possible, for example `SMA`, `MACD`,
`compute_indicator`, `trade_stats`, `TickAggregator`, or `AlertManager`
- Use the legacy lowercase aliases only when you want the old MCP-friendly
shortcuts and result shapes
- Use `about`, `methods`, `indicators`, and `info` to discover what is
available from inside an MCP client
---
## Stateful classes and object references
Class tools return stored object references instead of plain text placeholders.
For example, calling `TickAggregator` or `AlertManager` returns a payload like:
```json
{
"mcpServers": {
"ferro-ta": {
"command": "python",
"args": ["-m", "ferro_ta.mcp"]
}
}
"instance_id": "tickaggregator-0001",
"type": "ferro_ta.data.aggregation.TickAggregator",
"repr": "TickAggregator(rule='tick:2')"
}
```
Use that `instance_id` with:
- `describe_instance` to inspect the stored object and list public methods
- `call_instance_method` to call methods like `aggregate`, `update`,
`run_backtest`, or `to_dict`
- `delete_instance` to remove stored objects when you are done
If a tool returns a stored callable, use `call_stored_callable`.
---
## Callable references
Some ferro-ta APIs accept other callables, for example `benchmark`,
`log_call`, `traced`, or `multi_timeframe(indicator=...)`.
Pass public ferro-ta callables using:
```json
{"callable": "SMA"}
```
Pass stored objects using:
```json
{"instance_id": "function-0001"}
```
---
## Example prompts
Once connected, you can ask Claude (or any MCP-enabled AI) things like:
Once connected, you can ask an MCP-compatible client things like:

## Programmatic use (Python client)
You can also use the MCP handlers directly in Python without the server:
Use the server entrypoint:
```python
from ferro_ta.mcp import handle_list_tools, handle_call_tool
import numpy as np
from ferro_ta.mcp import create_server
server = create_server()
# server.run(transport="stdio")
```
Or call the handlers directly without starting the server:
```python
from ferro_ta.mcp import handle_call_tool, handle_list_tools
import json
# List tools
tools = handle_list_tools()
print([t["name"] for t in tools["tools"]])
print(len(tools["tools"]))
# Call RSI
close = list(np.cumprod(1 + np.random.default_rng(0).normal(0, 0.01, 50)) * 100)
result = handle_call_tool("rsi", {"close": close, "timeperiod": 14})
print(result)
close = [100, 101, 102, 103, 104]
result = handle_call_tool("SMA", {"close": close, "timeperiod": 3})
print(json.loads(result["content"][0]["text"]))
aggregator = json.loads(
handle_call_tool("TickAggregator", {"rule": "tick:2"})["content"][0]["text"]
)
bars = handle_call_tool(
"call_instance_method",
{
"instance_id": aggregator["instance_id"],
"method": "aggregate",
"args": [{"price": [1, 2, 3, 4], "size": [1, 1, 1, 1]}],
},
)
print(json.loads(bars["content"][0]["text"]))

# Options and Implied Volatility
ferro-ta provides optional helpers for implied volatility (IV) analysis
via the `ferro_ta.options` module. This document describes the scope,
data format, dependency strategy, and limitations.
---
`ferro-ta` exposes options analytics from `ferro_ta.analysis.options`.
## Scope
The `ferro_ta.options` module focuses on **IV series analysis**:
The module now covers both classic IV-series helpers and model-based option
analytics:
- **IV rank** — where today's IV sits relative to the min/max over a look-back window.
- **IV percentile** — fraction of observations over a look-back window at or below today's IV.
- **IV z-score** — how many standard deviations today's IV is above the rolling mean.
- `iv_rank`, `iv_percentile`, `iv_zscore`
- Black-Scholes-Merton pricing
- Black-76 pricing
- Delta, gamma, vega, theta, rho
- Implied volatility inversion
- Smile metrics and chain helpers
These functions accept any 1-D IV series (e.g. VIX daily closes, single-name
30-day IV, etc.) and return rolling statistics.
Heavy computation runs in Rust through the `_ferro_ta` extension.
**Out of scope (for now):** Black-Scholes pricing, Greeks, option chain
parsing, synthetic forward construction, dividend adjustment. For full
option-pricing functionality consider `py_vollib`, `mibian`, or similar.
## IV-series helpers
---
## Data format
All functions accept a 1-D NumPy array (or any array-like) of IV values.
IV values are typically in **percentage points** (e.g. VIX = 20 means 20%
annualised volatility), but the helpers are unit-agnostic — they only
compare values within the rolling window.
The original rolling helpers remain available and keep their public names:
```python
import numpy as np
from ferro_ta.options import iv_rank, iv_percentile, iv_zscore
from ferro_ta.analysis.options import iv_rank, iv_percentile, iv_zscore
# VIX-like daily close series
iv = np.array([18.5, 22.3, 19.1, 25.0, 30.2, 27.8, 21.4, 19.0])
rank = iv_rank(iv, window=5) # rolling IV rank in [0, 1]
pct = iv_percentile(iv, window=5) # rolling IV percentile in [0, 1]
z = iv_zscore(iv, window=5) # rolling z-score
rank = iv_rank(iv, window=5)
pct = iv_percentile(iv, window=5)
z = iv_zscore(iv, window=5)
```
---
These helpers accept a 1-D IV series and return rolling statistics with
`NaN` during the warmup period.
## Dependency strategy
## Pricing and Greeks
The `ferro_ta.options` module uses **only NumPy** (already a core dependency).
No additional packages are required for the helpers described here.
```python
from ferro_ta.analysis.options import greeks, implied_volatility, option_price
For advanced option analytics (Black-Scholes, volatility surface
interpolation), install the optional extra:
```bash
pip install "ferro-ta[options]"
price = option_price(100.0, 100.0, 0.05, 1.0, 0.20, option_type="call")
iv = implied_volatility(price, 100.0, 100.0, 0.05, 1.0, option_type="call")
g = greeks(100.0, 100.0, 0.05, 1.0, 0.20, option_type="call")
```
This may install additional packages in the future (e.g. `py_vollib`).
Conventions:
---
- Volatility is decimal annualized volatility: `0.20` means 20%.
- Rates are decimal annualized rates: `0.05` means 5%.
- `time_to_expiry` is measured in years.
- `model="bsm"` uses spot as the underlying input.
- `model="black76"` uses forward as the underlying input.
## API reference
## Smile and chain helpers
### `iv_rank(iv_series, window=252)`
```python
from ferro_ta.analysis.options import label_moneyness, select_strike, smile_metrics
Rolling IV rank.
strikes = [80, 90, 100, 110, 120]
vols = [0.30, 0.25, 0.20, 0.22, 0.27]
```
rank_t = (IV_t - min(IV[t-window+1:t+1])) / (max(IV[t-window+1:t+1]) - min(IV[t-window+1:t+1]))
metrics = smile_metrics(strikes, vols, 100.0, 0.5)
labels = label_moneyness(strikes, 100.0, option_type="call")
atm = select_strike(strikes, 100.0, selector="ATM")
delta_strike = select_strike(
strikes,
100.0,
selector="DELTA0.25",
option_type="call",
volatilities=vols,
time_to_expiry=0.5,
)
```
Returns values in [0, 1]. NaN for the first `window - 1` bars.
## Related futures analytics
### `iv_percentile(iv_series, window=252)`
Rolling IV percentile: fraction of the *window* bars whose IV was at or
below the current value.
### `iv_zscore(iv_series, window=252)`
Rolling z-score: `(IV_t - rolling_mean) / rolling_std`.
---
## Limitations
- All functions use **O(n × window)** time complexity (pure Python loops).
For large windows or series consider vectorised alternatives.
- No option chain support; the module assumes IV series as input.
- Streaming (bar-by-bar) versions of these functions are not yet
implemented. For live use, maintain a rolling buffer and call the
functions on the buffer at each bar.

## Benchmark Tooling
The benchmark suite now includes a small set of machine-readable scripts for
performance work beyond the full pytest benchmark table:
- `python benchmarks/bench_batch.py --json batch_benchmark.json`
- `python benchmarks/bench_streaming.py --json streaming_benchmark.json`
- `python benchmarks/profile_runtime_hotspots.py --json runtime_hotspots.json`

- `python benchmarks/run_perf_contract.py --output-dir benchmarks/artifacts/latest`
- `python benchmarks/check_hotspot_regression.py --input runtime_hotspots.json`
The WASM bindings also ship with a Node benchmark:
- `cd wasm && wasm-pack build --target nodejs --out-dir pkg`
- `node bench.js --json ../wasm_benchmark.json`
## SIMD And Build Flags
Distributable wheels should stay on the portable release profile:
- `cargo`/`maturin` release build
- `lto = true`
- `codegen-units = 1`
- no architecture-specific `target-cpu=native` in shipped artifacts
For local source builds, there are two opt-in tuning levers:
```bash
# Portable SIMD-enabled local build
uv run maturin develop --release --features simd
# Maximum local tuning for your current machine only
RUSTFLAGS="-C target-cpu=native" uv run maturin develop --release --features simd
```
Policy:
- Ship portable wheels with the default release settings.
- Use `--features simd` for measured local/source wins.
- Reserve `target-cpu=native` for developer workstations or private deploys,
because those binaries are not portable across CPU families.

- Indicators are run in a Python loop (one call per indicator); no bulk API.

ferro_ta.options Options and Implied Volatility Helpers
=========================================================
ferro_ta.analysis.options Rust-backed derivatives analytics for options.
Optional module that provides helpers for options/IV analysis when supplied
with an implied-volatility series (IV series as input). All heavy compute
delegates to Rust via ``ferro_ta`` core; this module is a thin orchestration
layer.
.. note::
Options support is **optional** and does not require any additional
third-party libraries beyond ``numpy``. For advanced option-pricing
functionality (e.g. Black-Scholes, Greeks) install the optional
``ferro_ta[options]`` extra which may pull in additional dependencies.
See ``docs/options-volatility.md`` for the full design doc.
Quick start
-----------
>>> import numpy as np
>>> from ferro_ta.analysis.options import iv_rank, iv_percentile
>>>
>>> # Synthetic IV series (e.g. VIX or single-name IV)
>>> rng = np.random.default_rng(42)
>>> iv = rng.uniform(10, 40, 252)
>>>
>>> rank = iv_rank(iv, window=252)
>>> pct = iv_percentile(iv, window=252)
API
---
iv_rank(iv_series, window)
Rolling IV rank: where is today's IV relative to min/max over *window* bars?
Returns values in [0, 1] (NaN during warm-up).
iv_percentile(iv_series, window)
Rolling IV percentile: fraction of observations over *window* bars that are
today's IV. Returns values in [0, 1] (NaN during warm-up).
iv_zscore(iv_series, window)
Rolling IV z-score: (IV - rolling_mean) / rolling_std over *window* bars.
Returns z-score values (NaN during warm-up).
This module preserves the legacy IV-series helpers and expands them with
pricing, Greeks, implied-volatility inversion, smile analytics, and strike
selection helpers suitable for research and simulation workflows.
