What is a Swing Failure Pattern?
A swing failure pattern (SFP) is a failed raid on a prior swing point. Price trades beyond a previous swing high or low, typically on a wick, but cannot hold there and closes back on the original side of the level. A bearish SFP sweeps a prior high and closes back below it; a bullish SFP sweeps a prior low and closes back above it. The lineage is older than the modern name: Victor Sperandeo described the same event as the 2B rule, and Wilder's RSI failure swing is the oscillator-side namesake. Some sources also use 'failure swing' for the softer case where price never reaches the prior extreme at all, so definitions are worth checking.
The pattern matters because of what sits beyond swing points: stops from existing positions and entry orders from breakout traders, the resting liquidity pool. The push beyond the extreme fills those orders, and the failure to hold suggests that once they were spent, no genuine initiative interest stood behind the new price. What remains is a trapped crowd on the wrong side and fresh evidence that, for now, one direction is empty. That is why SFPs at range extremes and higher-timeframe levels are read as reversal triggers, with the honest caveat that plenty of raids simply pause and continue, which is why many traders demand the close back inside plus confirmation.
How to identify a swing failure pattern
The SFP is defined by three things: a real prior extreme, a violation of it, and a failed close.
- 1Locate a clear prior swing high or low, ideally one that has stood long enough for stops to accumulate beyond it.
- 2Watch for the violation: a candle trades beyond the extreme, printing a marginal new high or low. On its own this is just a sweep or a breakout attempt.
- 3Require the failed close: the candle closes back on the original side of the level. Stricter readings demand it on the same candle; looser ones accept the following candle. The further back inside the close, the cleaner the pattern.
- 4Add confirmation if your model calls for it: a lower-timeframe change of character or a close through the sweep candle's opposite extreme are common follow-through checks.
How traders use it
- As a reversal entry at extremes: short a bearish SFP of a swing high (or buy the bullish mirror) with the stop just beyond the sweep wick, targeting a rotation back through the trading range. The wick gives the trade an unusually well-defined invalidation.
- As sweep-plus-proof in Smart Money workflows: the SFP is the visible candlestick print of a stop run, and many traders treat it as the moment a suspected raid becomes tradeable rather than hypothetical.
- As an exit prompt for trend riders: an SFP against the position at a major level is a common cue to take profit or tighten stops, since the fuel beyond the level has just been spent.
- As the seed of codified setups: Sperandeo's 2B and the turtle soup play both wrap SFP logic, a failed marginal new extreme, in explicit entry and stop rules.
Swing Failure Pattern vs related concepts
Liquidity Sweep: The sweep names the raid itself: stops beyond a level being taken, whatever happens next. The SFP adds the requirement that the raid fails, with a close back inside. Every SFP contains a sweep; a sweep only becomes an SFP once the reclaim prints.
False Breakout: The false breakout is the broader category: any failed break of any level, range boundary, or pattern line, possibly taking several bars to fail. The SFP is the tight, swing-point-specific version, usually judged wick-and-close on one or two candles.
Turtle Soup: Turtle soup is a rule set built on the same failure: fading a marginal break of a 20-day extreme, originally aimed at the entries of mechanical breakout systems. The SFP is the discretionary structure event; turtle soup fixes the lookback and mechanics into a defined setup.

Swing Failure Pattern FAQ
What is the difference between an SFP and a 2B reversal?
They describe essentially the same event, decades apart. Sperandeo's 2B rule flagged a marginal new extreme that fails to follow through as an early reversal tell within his 1-2-3 framework. The modern SFP, popularized in crypto and futures circles, tightens the definition around the candle close: the violation must close back inside the prior extreme to count.
Does an SFP need to close back inside the level?
In the common reading, yes: the failed close is what separates an SFP from an ordinary sweep or a breakout in progress. A wick beyond the level means nothing until the bar completes. Conventions differ on whether the reclaim must happen on the sweep candle itself or may arrive on the next one; intrabar, a forming SFP can still turn into continuation.
How reliable is the swing failure pattern?
There is no honest fixed number. Behavior varies with location: SFPs at higher-timeframe levels and range extremes, against a stretched move, have a different character from those printed mid-trend, and many raids resolve as continuation after a pause. Treat the pattern as a scenario with a defined invalidation at the wick extreme rather than a signal with a known win rate.
