Tweezer definition Poached from investopedia:
Understanding Tweezers:
Tweezer patterns are reversal patterns and occur when two or more candlesticks touch the same bottom for a tweezer bottom pattern, or when two or more candlesticks touch the same top for a tweezer top pattern.
Tweezer bottoms are considered to be short-term bullish reversal patterns, whereas tweezer tops are thought to be bearish reversals. Essentially, with both formations, either buyers or sellers were not able to push the top or bottom any further. Both types of patterns require close observation and research to be interpreted and used correctly.
