Updated A Reversal Candle Detector (15m)

Reversal Candle Detector (15m)
Detects potential reversal candles on the 15m timeframe based on wick spike analysis. Works on any lower timeframe chart.
A signal triggers when the candle range exceeds the minimum threshold and the upper or lower wick is at least 50% of the total range — a classic rejection pattern.
🔴 Short — long upper wick
🟢 Long — long lower wick
Includes target zone rectangles, range % label on every candle, live updates on the forming candle, and alerts before and at candle close.
⚠️ Alerts work correctly only when the chart is set to the 15m timeframe.
Settings:
Min candle range threshold (separate for upper and lower spike)
Min wick % of total range
Rectangle height, width and transparency
Range % label size and color (yellow if ≥ 1.5%)
Price label and arrow symbol toggle
