[ ABOUT ]

Detects classic reversal patterns by analyzing sequences of local price peaks (highs) and troughs (lows). Currently implements double-top detection by checking whether the two most recent peaks are within 3% of each other — a threshold that accounts for normal price variance while filtering out coincidental proximity.

The pattern list is designed to be extensible: add head-and-shoulders detection by checking for a higher middle peak flanked by two roughly equal lower peaks, or double-bottom by applying the same logic to troughs. Return values are string labels that Claude can interpret and include in a natural language narrative.

[ USAGE EXAMPLE ]

example.py

patterns = find_patterns(highs, lows, close)
if "double_top" in patterns:
    signal = "sell"

[ FULL CODE ]
