Stick Sandwich (CDLSTICKSANDWICH)

Summary

A three-candle bullish reversal pattern: two black candles (1st and 3rd) sandwiching a white candle, where the 3rd black candle closes at the same level as the 1st (the "bread"). A hit signals a bullish reversal (code comment notes it is significant in a downtrend, which the function does not verify).

Notes

Although classically a bullish reversal (and TA-Lib only emits +100), Bulkowski's testing found it actually acts as a bearish continuation 62% of the time — despite that, it still ranks a respectable 14th of 103 patterns for overall performance. (thepatternsite.com)
