Unusual Volume at Support (0.5% Proximity 3x Volume)

Unusual Volume Near Support\n\nSTRATEGY DESCRIPTION:\nDetects stocks trading near their previous trading day's support level (previous day's low) with unusually high current candle volume (>3x last 20-candle average volume).\n\nCORE LOGIC (Step by Step):\n\n1. Fetch previous day's low (support level)\n2. Check if current price is within 0.5% of that support level:\n distance = |current_price - support_level| / support_level\n IF distance < 0.005 (within 0.5% of support):\n3. Compare current candle volume with last 20 candles average volume\n4. IF volume > 3x average:\n SIGNAL DETECTED!\n\nPURPOSE:\nIdentify possible support-based reversals where buyers may be strongly defending a key price level.\n\n[CHANGED: Proximity tightened from 1% to 0.5%, volume threshold increased from 2x to 3x]
