Three & Four Bar Reversal Pattern

Three & Four Bar Reversal Pattern identifies short-term reversal candlestick setups directly on your chart, based on a strict closing-price confirmation rather than just wick penetration — making signals more reliable for intraday and swing trading decisions.

WHAT IT DETECTS

3-Bar Reversal
A classic three-candle reversal:

Bullish: two consecutive bearish candles followed by a bullish candle that closes above the high of the first bearish candle.
Bearish: two consecutive bullish candles followed by a bearish candle that closes below the low of the first bullish candle.

Requiring the close (not just the wick) to break the reference level filters out weaker, unconfirmed reversal attempts.

4-Bar Reversal (optional)
An extended version of the pattern for setups where the reversal takes one extra candle to confirm:

Two small same-direction candles, followed by a transition candle in the opposite direction, followed by a large breakout candle whose body exceeds the combined body size of the previous three candles, and whose close breaks through the high/low of the first candle.
Built-in logic prevents a 4-bar signal from overlapping with an already-completed 3-bar signal on the same candles, so you don't get redundant markers on the chart.

FEATURES

Independent toggles for bullish and bearish signals
Customizable colors for bullish/bearish markers
Optional 4-bar pattern detection, clearly distinguished from 3-bar signals with on-chart labels ("3" / "4")
Configurable reference line (style: solid/dashed/dotted, adjustable width) marking the breakout level
Built-in alert conditions for all four signal types (bullish/bearish, 3-bar/4-bar)

HOW TO USE

Add the indicator to your chart.
Watch for triangle markers below/above candles — these mark confirmed reversal closes.
Enable "4-Bar Pattern Detection" in settings if you also want the extended 4-candle version.
Set alerts on any of the four conditions to get notified in real time.

NOTES
This tool is designed to highlight potential reversal setups, not to generate standalone buy/sell signals. Always combine it with your own risk management, trend context, and confluence factors (support/resistance, volume, higher-timeframe structure, etc.). Past patterns do not guarantee future results.

版本注释

Reference line is now split into two parts:

Breakout line: marks the level broken by the signal candle (style/width configurable).
Extended line: projects the breakout level forward (default 24 bars, adjustable) so it can be used as a limit order reference. It automatically stops extending once price touches the level again, or once the max length is reached.
