FS instant (extremo 4H) - R.AlvaradoFS Instant (4H Extremes) – R. Alvarado automatically detects and marks Failure Swings (FS) at 4H highs and lows when they are formed during the final 15-minute candle (:45) of each 4-hour block, specifically at 00:45, 04:45, 08:45, 12:45, 16:45, and 20:45 New York time. The indicator runs exclusively on the 15-minute timeframe and evaluates whether that candle printed the high or low of the completed 4H candle using a configurable tick tolerance, instantly labeling the event at candle close. This tool is designed for traders who want to identify liquidity events and potential reversals (Failure Swings) in real time while aligning lower-timeframe execution with higher-timeframe structure, and should be used as a contextual aid rather than a standalone trading signal.
