Tweezer Bottom
A Tweezer Bottom is a two-candle bullish reversal pattern where two consecutive candles reach nearly the same low price. The matching lows suggest that price hit a floor that held — a support level where buyers stepped in both times. It's most meaningful after a downtrend.

Pattern Anatomy
- Two consecutive candles with nearly identical low prices
- The first candle is typically bearish (sellers pushing down) and the second is bullish (buyers pushing back up)
- The candle bodies, wicks, and colors can vary — the key feature is the matching lows
- The "tweezer" name comes from the visual resemblance to a pair of tweezers with matching tips pointing downward
How to Interpret
- Most significant after a sustained downtrend — signals potential reversal
- Matching lows suggest a price floor or support level that held firm
- Stronger when the second candle is clearly bullish with a long body
- Volume on the second candle adds conviction to the reversal signal
- Best when lows coincide with a known support level or round number
How Engulfy Detects the Tweezer Bottom
- Look at two consecutive candles
- Calculate the absolute difference between their Low prices: |prev.Low − curr.Low|
- Calculate a small tolerance based on the price level to account for bid-ask spread and rounding
- If the difference is within the tolerance, the lows are considered matching
- Pattern is classified as a Tweezer Bottom (bullish reversal signal)
Engulfy uses a small calibrated tolerance to allow for minor price differences due to bid-ask spread and tick-size rounding. Two candles don't need exactly identical lows — just very close.
Expert References
- Steve Nison, Japanese Candlestick Charting Techniques — describes Tweezer Bottoms as a minor reversal signal that gains significance when combined with other bullish patterns or when appearing at a support level
- Like its top counterpart, most useful as confirmation of bullish sentiment rather than a primary trading signal
Controversy & Limitations
- Relatively weak as a standalone signal — best used as confirmation alongside other bullish patterns or indicators
- The tolerance threshold (how "close" the lows need to be) varies by implementation, making cross-platform comparisons inconsistent
- Some analysts require the first candle to be bearish and the second bullish; others accept any color combination
