Development setup
|
|
-----------------
|
|
|
|
Prerequisites: Rust stable toolchain, Python 3.10+, and ``maturin``.
|
|
|
|
.. code-block:: bash
|
|
|
|
git clone https://github.com/pratikbhadane24/ferro-ta.git
|
|
cd ferro-ta
|
|
pip install maturin numpy pytest pytest-cov
|
|
maturin develop --release
|
|
pytest tests/
|
|
|

|
|
Adding a new indicator
|
|
-----------------------
|
|
|
|
1. **Rust** — implement the function in the appropriate ``src/<module>/``
|
|
directory (e.g. ``src/overlap/mod.rs`` and ``src/overlap/sma.rs``). Follow
|
|
the existing patterns: slice inputs, ``Vec<f64>`` output, leading NaN for
|
|
warm-up bars, a ``#[pyfunction]`` decorator, and registration in the
|
|
module's ``register(m)`` function.
|
|
|
|
2. **Python** — add a thin wrapper in the matching ``python/ferro_ta/*.py``
|
|
module using the ``_to_f64`` helper. Export it in ``__all__``.
|
|
|
|
3. **Re-export** — add the function to ``python/ferro_ta/__init__.py``'s
|
|
``__all__`` list and import block.
|
|
|
|
4. **Type stub** — add a type annotation to ``python/ferro_ta/__init__.pyi``.
|
|
|
|
5. **Tests** — add at least one test class in ``tests/test_ferro_ta.py``
|
|
covering output length, NaN count, and a known-value check.
|
|
|
|
6. **README** — add a row to the appropriate accuracy table.
|
|
|
|
|
|
Code style
|
|
----------
|
|
|
|
- Rust: ``cargo fmt`` (enforced in CI) and ``cargo clippy -- -D warnings``
|
|
- Python: PEP 8; function names in UPPER_CASE to match TA-Lib convention.
|
|
- All public Python functions should have NumPy-style docstrings.
|
|
|
|
|
|
Running tests
|
|
-------------
|
|
|
|
.. code-block:: bash
|
|
|
|
# Python tests
|
|
pytest tests/ -v
|
|
|
|
# Rust format check
|
|
cargo fmt --check
|
|
|
|
# Rust lints
|
|
cargo clippy --release -- -D warnings
|
|
|
|
# Optional: TA-Lib comparison tests (requires ta-lib installed)
|
|
pytest tests/test_vs_talib.py -v
|
|
|
|
|
|
Type checking
|
|
-------------
|
|
|
|
The package is typed (PEP 561). To run mypy::
|
|
|
|
pip install mypy numpy
|
|
mypy python/ferro_ta --ignore-missing-imports
