# 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.

## Inputs

- `inPriceOHLC` — OHLC price series (open, high, low, close)

## Outputs

- `outInteger` — -100 when the pattern is detected (always bearish), 0 otherwise; never emits +100

## Parameters

- `optInPenetration` — Fraction of candle 1's real body that candle 2's close must penetrate below close[i-1] (default 0.5); larger values require deeper penetration
