Tweezer Bottom: matching lows and what they actually confirm
The mirror of the tweezer top — two consecutive bars with near-identical lows — read as a support observation, not a strong standalone signal.

Open the chartWhat it measures
A tweezer bottom is two consecutive bars whose lows land at essentially the same price, typically the first down and the second up.
It measures a level that held twice in a row rather than once.
How it is calculated
These are the steps Basis performs, verified against the published definition.
- 1
Two consecutive bars with lows within a small tolerance of each other.
- 2
The classic version has the first bar closing down and the second closing up.
How to read it
- More useful as confirmation that a level is being defended than as an independent reversal trigger.
- Stronger after an extended decline than when the two lows occur early in a move.
Where it misleads
As with the tweezer top, two bars sharing a similar low is common enough by chance that the pattern needs the surrounding trend to mean anything.
