# CDL3BLACKCROWS

## Summary

A four-bar pattern: a white candle followed by three consecutive black (down) candles with successively lower closes, each opening inside the prior black's real body. It is a bearish reversal signal. A hit (-100) signals a bearish reversal.

## Notes

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

## Inputs

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

## Outputs

- `outInteger` — -100 when the bearish pattern is detected, 0 otherwise. Never emits +100
