**430x faster** backtesting. Test your trading strategies in seconds, not minutes.

## API Stability Guarantee

**Qrucible v1.0.0+ follows [Semantic Versioning](https://semver.org/).** This means:

- **Patch releases** (1.0.x): Bug fixes only. No breaking changes.
- **Minor releases** (1.x.0): New features, backwards compatible. Your existing code will continue to work.
- **Major releases** (x.0.0): Breaking changes. Migration guide will be provided.

**The following public API is stable:**

| API | Stability |
|-----|-----------|
| `run_backtest(data, config)` | Stable |
| `run_backtest_with_signals(data, signals, config)` | Stable |
| `grid_search(data, configs, metric, top_n)` | Stable |
| `load_bars(path)`, `load_bars_csv(path)`, `load_bars_parquet(path)` | Stable |
| `StrategyConfig` and all parameters | Stable |
| `BacktestResult` and all fields | Stable |
| Order type configs (`TrailingStopConfig`, `BreakEvenConfig`, etc.) | Stable |
| `BarData` class | Stable |

**Internal APIs** (names starting with `_`) may change without notice.

## Quick Start (Beginners Start Here!)

**3 lines of code. That's all you need.**

```bash
pip install qrucible
```

```python
import qrucible_easy as ez

# That's it! Runs a backtest with sample data
result = ez.backtest()
print(result)
```

Output:
```
  Backtest Results: Great!
  ────────────────────────────────────────
  Total Return:        12.34%
  Total Trades:            47
  Win Rate:             53.2%
  Sharpe Ratio:          1.42
  Max Drawdown:          8.21%
```

### Use Your Own Data

```python
# From a CSV file
result = ez.backtest("my_prices.csv")

# From a pandas DataFrame
result = ez.backtest(df)

# From a list of prices
result = ez.backtest([100, 102, 101, 105, 103, 108, 110])
```

### Try Different Strategies

```python
# Moving Average Crossover (default)
result = ez.backtest_ma(fast=10, slow=30)

# RSI - buy oversold, sell overbought
result = ez.backtest_rsi(period=14, oversold=30, overbought=70)

# MACD crossover
result = ez.backtest_macd()

# Bollinger Bands
result = ez.backtest_bollinger()

# Compare all strategies at once
results = ez.compare_strategies()
```

### Interactive Demo

```python
import qrucible_easy as ez
ez.demo()  # See Qrucible in action!
```

Or run the quickstart script:
```bash
python scripts/quickstart.py
```

**That's the beginner guide!** The rest of this README covers advanced features.

## What is Qrucible?

Hybrid, stateful backtester with a Rust hot path and a clean Python API. Qrucible executes path-dependent logic (position sizing that reacts to wins/losses, stops, and exits) at vectorized speeds by keeping the critical loop in Rust and fanning out parameter grids with `rayon`. Docs: https://charlesfreidenreich.github.io/Qrucible/

**430x faster** than equivalent Python code. 1,000+ configs/second grid search throughput.

## Install

```bash
pip install qrucible
```

For the beginner-friendly API with pandas support:
```bash
pip install qrucible[easy]
```

Prebuilt wheels are published for Linux, macOS, and Windows with Parquet and common compression codecs enabled (brotli, gzip, lz4, snappy, zstd). No Rust toolchain is required when installing from PyPI wheels.

## Prerequisites (for local builds)
- Python 3.10+
- Rust toolchain

## Setup (venv + deps)
```bash
python -m venv .venv
source .venv/bin/activate
python -m pip install -r requirements.txt
```

## Build and install (editable)
```bash
maturin develop --release
```

Cargo config forces `PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1` so builds succeed with CPython 3.13 until PyO3 adds official support.

## One-command setup
```bash
make setup
```

## External Signal Mode

Bring your own signals (computed in Python/NumPy), and let Qrucible handle sizing, stops, take-profit, and metrics at Rust speed:

```python
from qrucible import StrategyConfig, run_backtest_with_signals
import numpy as np

# Compute your own signals: 1=long, -1=short, 0=hold
close_prices = bars[:, 5]
sma = np.convolve(close_prices, np.ones(20)/20, mode='same')

signals = np.zeros(len(bars), dtype=np.int8)
signals[close_prices < sma] = 1
signals[close_prices > sma] = -1

config = StrategyConfig(
    strategy_type="EXTERNAL",
    stop_loss=0.02,
    take_profit=0.04,
)
result = run_backtest_with_signals(bars, signals, config)
```

## Grid Search

```python
grid = [
    StrategyConfig(
        strategy_type="MA_CROSS",
        fast_window=f,
        slow_window=s,
        ma_type=ma,
        stop_loss=0.02,
        take_profit=0.04,
    )
    for f in (5, 10, 15, 20)
    for s in (30, 50, 100, 200)
    for ma in ("SMA", "EMA", "WMA")
]

# Sort by Sharpe ratio, get top 10
top = grid_search(bars, grid, metric="sharpe", top_n=10)
for r in top:
    print(f"Sharpe: {r.sharpe:.3f}, Return: {r.total_return:.2%}")
```

## Multi-Asset Support

```python
# CSV or Parquet with schema: [ts_epoch_us, asset_id, open, high, low, close, volume]
bars = load_bars("data/multi_asset_bars.parquet")
result = run_backtest(bars, config)
```
