A tweezer is two (or more) adjacent candles that reach almost exactly the same high (tweezer top) or low (tweezer bottom). The matched extreme shows price tested a level twice and was rejected both times — a small but clean double-rejection.
How to read it
A tweezer top is typically a green candle followed by a red one sharing the same high: buyers reached a price, failed there twice, and sellers took over. A tweezer bottom is the reverse at lows. The pattern is most reliable when the shared level lines up with existing support or resistance — then it is a precise, two-candle confirmation of that level holding.
Strength and context
On its own a tweezer is a minor signal; at a major level, after an extended move, it can mark a clean turn. Treat it as confirmation of a level you already respect rather than a reason to fade price in open space.
