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 — a floor that absorbed two separate attempts to break it.
Only the lows have to match; the bodies, upper wicks and closes are free to differ, which is what makes the pattern quick to spot but limited in what it proves by itself.
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.
- 3
No requirement on body size or wick length beyond the matched lows — a tweezer bottom can form from two large bars or two small ones.
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.
- A subsequent bar that holds above the matched low adds real weight; one that promptly breaks it converts the pattern into a failed floor rather than a defended one.
- Comparable volume on both touches of the low says the same participants are still defending it; a second touch on visibly lighter volume suggests the level is being tested with less conviction than the first time.
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. Reading it as a guaranteed bounce ignores that a level can be tested and hold twice, then still give way on a third attempt once selling pressure regathers.
