A tweezer top is two adjacent candles with nearly identical highs — price pushed to the same level twice and got rejected both times. A tweezer bottom is two candles sharing nearly the same low — buyers defended the same price twice. The matching extreme, resembling the two prongs of a tweezer, is the signal.

Why the matched level matters

A single rejection at a price is one data point. Two candles failing at the exact same level says there's real supply (tweezer top) or demand (tweezer bottom) sitting there — a line the market couldn't cross. It's a compact, two-candle cousin of a double top or bottom, and it works for the same reason: a level tested twice and held is meaningful.

Confirmation

The strongest tweezers pair with other clues — the second candle being a reversal shape (a hammer at a tweezer bottom, a shooting star at a top), or appearing at a known support/resistance level. As with every candle pattern, wait for a follow-through candle to confirm the reversal rather than acting on the matched wicks alone.

One rejection is a maybe. The same rejection twice, to the tick, is the market telling you where it won't go.

Where it fits

Tweezers are most reliable at meaningful levels after an extended move — a double rejection at prior-day highs or VWAP is a real tell. Mid-range, two candles with similar wicks are coincidence. The level, the confirmation, and the regime turn a shape into a signal.
