# Centaur Technical Indicators

A production-ready Python library providing 60+ technical indicators for financial analysis, built on a high-performance Rust backend. 

Part of the Centaur Capital ecosystem.

Looking for the Rust crate? See: [ChironMind/CentaurTechnicalIndicators-Rust](https://github.com/ChironMind/CentaurTechnicalIndicators-Rust)

## 🚀 Getting Started

**1. Install the package:**

```shell
pip install centaur_technical_indicators
```

**2. Calculate your first indicator:**

```python
import centaur_technical_indicators as cti

prices = [100.2, 100.46, 100.53, 100.38, 100.19]

ma = cti.moving_average(
    prices,
    "simple"
)
print(f"Simple Moving Average: {ma}")
```

Expected output:
```
Simple Moving Average: 100.352
```

### Examples

A reference of how to call each function can be found in the tests:

- [Reference Examples](./tests/)

Clone and run:

```shell
$ source you_venv_location/bin/activate

$ pip3 install -r test_requirements.txt

$ maturin develop

$ pytest .

```

### Library Structure

- Modules based on their analysis areas (**`moving_average`**, **`momentum_indicators`**, **`strength_indicators`**...)
- `bulk` & `single` function variants  
  - `bulk`: Compute indicator over rolling periods, returns a list.
  - `single`: Compute indicator for the entire list, returns a single value.
- `types` used to personalise the technical indicators (**`moving_average_type`**, **`deviation_model`**, **`constant_model_type`**...)

## 🧠 Explanation & Design

### Why Centaur Technical Indicators?

- **Performance:** Rust-powered backend for maximal speed, safety, and low overhead.
- **Configurability:** Most indicators are highly customizable—tweak calculation methods, periods, or even use medians instead of means.
- **Breadth:** Covers a wide range of technical indicators out of the box.
- **Advanced Use:** Designed for users who understand technical analysis and want deep control.

**Note:** Some features may require background in technical analysis. See [Investopedia: Technical Analysis](https://www.investopedia.com/terms/t/technicalanalysis.asp) for a primer.

## 📊 Performance Benchmarks

Want to know how fast the library runs in real-world scenarios?  
We provide detailed, reproducible benchmarks using realistic OHLCV data and a variety of indicators.

## Benchmarks summary (Raspberry Pi 5)

All results are produced on a Raspberry Pi 5 (RPi5) and reported as microseconds per call (min/mean/median) and derived ops/sec. Each suite is run in two modes:
- single: run the indicator repeatedly for timing small, per-call latency
- bulk: process larger arrays to measure throughput-oriented workloads

Headline observations from the momentum suite (large 10Y dataset)
- Ultra‑lightweight indicators achieve sub‑microsecond latency per call:
  - ROC single: ~0.11 µs (≈8.72e+06 ops/sec); bulk: ~86 µs (≈1.16e+04 ops/sec)
  - OBV single: ~0.13 µs (≈7.85e+06 ops/sec); bulk: ~130 µs (≈7.7e+03 ops/sec)
- RSI single-call latency ranges roughly 45–115 µs depending on averaging method; bulk ranges ~560–3600 µs
  - Averaging method impact (fast → slow): simple/mean/exponential ≈ median < mode
- Stochastic (fast/slow/slowest) single: ~36–98 µs; bulk: ~109–2600 µs (mode again the slowest)
- CCI families:
  - “standard/mean/median/mode” single calls mostly ~39–155 µs; bulk ~230–3600 µs
  - “ulcer” variant is significantly heavier: single ~6.8–6.9 ms; bulk ~1.0–2.1 ms
- MACD line and signal line single: ~32–80 µs; bulk: ~170–4,000+ µs depending on smoothing and dataset
  - McGinley MACD line single is among the fastest (~32–33 µs); bulk ~300 µs
- Chaikin Oscillator single: ~140–300 µs; bulk: ~500–2,900 µs
- PPO single: ~36–151 µs; bulk: ~175–5,700 µs
- CMO single: ~45 µs; bulk: ~505 µs

These patterns (simple/mean/exponential being fastest; median slightly slower; mode slowest; “ulcer” notably heavy) are consistent across indicator variants and hold across single vs bulk modes.
