The tweezers formation always involves two candles. At a tweezers top, the high price of two nearby sessions is identical or very nearly so.

At a tweezers bottom, the low price of two sessions that come in close succession is the same. For simplicity, lets talk just about the tweezers bottom.
In some instances, the tweezers bottom is formed by two real candlestick bodies that make an identical low.
In other instances, the lower shadows of two nearby candles touch the same price level and the stock then bounces higher. A third possibility is that the lower shadow of one day and the real body of a nearby session hit the same bottom level.
