CDLDARKCLOUDCOVER

Summary

A two-candle bearish reversal pattern: a long white candle followed by a black candle that opens above the prior high and closes deep into the prior white body past a penetration threshold. Signals a potential top. A hit (-100) is a bearish reversal signal, most meaningful after an uptrend.

Notes

Does not verify the preceding uptrend the bearish reversal classically assumes.
