Swing Failure Pattern [ SFP ] - FloAlgoThis indicator detects Swing Failure Patterns (SFP) — a Smart Money Concepts technique that identifies liquidity sweeps followed by a Change in State of Delivery (CISD), signaling potential price reversals.
How It Works
The script operates in three stages:
Liquidity Sweep Detection — Identifies when price briefly breaks above a pivot high or below a pivot low, sweeping resting liquidity beyond those levels.
CISD Confirmation — Validates the sweep by detecting a Change in State of Delivery: a candle close that reverses back through a key open level, confirming institutional rejection.
Signal Trigger — A bullish or bearish SFP signal is confirmed only when both the sweep and CISD occur within the defined patience window, reducing false positives significantly.
Exit System — 5-Layer Logic
Rather than relying on a fixed take profit, this script uses a dynamic multi-layer exit system designed to protect capital and lock in gains:
Initial Stop Loss — Set at the high/low of the signal candle for immediate invalidation
Trailing Stop — Tracks extreme price movement and trails by ATR × multiplier, activating after a minimum number of bars to avoid premature exits
Reversal Candle — Exits on an opposing engulfing candle once the trade is in motion
Timeout — Hard exit after a maximum number of bars
Trend Flip — Exits if CISD confirms a full trend reversal against the position
