Example From Trading View

Defining the Tweezer Bottom Candlestick Pattern Criteria 

The Tweezer Bottom candlestick pattern is defined by specific criteria that signal a potential bullish reversal. Here are the key criteria for identifying a Tweezer Bottom:

  1. Two Adjacent Candlesticks: The pattern consists of two candlesticks that are side by side.
  2. Similar Lows: Both candlesticks have almost the same low points. This alignment is essential for the pattern and creates a level line appearance at the bottom.
  3. First Candle Bearish: The first candle in the pattern is typically bearish, suggesting a continuation of the downtrend.
  4. Second Candle Bullish: The second candle is bullish, indicating a shift in market sentiment. The bullish candle doesn’t need to engulf the first candle but should show a clear change in momentum.
  5. Trend Context: The Tweezer Bottom is most significant when it occurs after a notable downtrend, indicating a potential reversal in the trend.
