# Harmonic Patterns ## Purpose The Fibonacci geometry school uses precise ratio relationships to identify price patterns: | Pattern | B-Point Retracement | D-Point Retracement | Direction | |------|---------|---------|------| | Gartley | 0.618 XA | 0.786 XA | Reversal | | Bat | 0.382-0.5 XA | 0.886 XA | Reversal | | Butterfly | 0.786 XA | 1.27 XA | Reversal | | Crab | 0.382-0.618 XA | 1.618 XA | Reversal | ## Core Concepts - **XABCD five-point pattern**: a price structure defined by precise Fibonacci ratios - **PRZ (Potential Reversal Zone)**: the convergence area around point D, where reversal probability is high - Bullish pattern (point D at the bottom) → buy signal - Bearish pattern (point D at the top) → sell signal ## Dependencies ```bash pip install "vibe-trading-ai[harmonic]" ``` `pyharmonics` is optional. If the extra is not installed, the example signal engine falls back to the bundled detector. ## Parameters | Parameter | Default | Description | |------|--------|------| | is_stock | False | Whether the instrument is a stock (affects analysis parameters) | ## Signal Convention - `1` = long, `-1` = short, `0` = stand aside
