CDLHAMMER

Summary

Single-candle pattern: a small real body at the top of the range with a long lower shadow and little or no upper shadow, sitting at or near the prior candle's low. Bullish reversal signal. A hit (+100) flags a potential bullish reversal.

Notes

Does not verify the preceding downtrend that the pattern classically assumes; confirm the trend context yourself.
