1. Look for 50% candles and tight bases
2. Locate mother candles and watch if next child candles (inside candles, haramis, dojis, spinning tops) close above/below the mother candle’s open/close and makes a lower low (higher high) above below the mother candle's price range
3. If price closes above/below mother candle, it will negate a CP and will make it a Valley/Peak
4. Bullish/bearish engulfing patterns are common as CPs, there is a video that explains how to draw them here
5. Marubozu candles are not 50% candles but they can be part of a CP if they are at a good location or attained an important event (took out an important HTF zone or flip zone)
