CDLADVANCEBLOCK

Summary

Three-candle bearish reversal pattern: three white candles with consecutively higher closes whose advance weakens (progressively smaller bodies and/or lengthening upper shadows). Signals that an uptrend's advance is being blocked. A hit (-100) is bearish: the advance is stalling/blocked; meaningful mainly within an existing uptrend.

Notes

Does not verify the prior uptrend the pattern classically assumes for significance.
