Judas swing: an early move that may mislead
The first move after a session opens can look convincing. It can also keep going.
Study an early reversal hypothesis without assuming every opening move is a trap.
Judas swing is ICT vocabulary for an early misleading move before a later opposite move. Its label is easiest to assign after the outcome, which creates hindsight risk.
For our study, define the session start, an initial observation period and a reference range in advance. Record every qualifying opening move, including those that continue.
A reversal needs its own confirmation and invalidation. Seeing a price move away from the open is not enough to establish deliberate deception or a reason to fade it.
Session times and volatility depend on the product and calendar. Separate news-driven days, holidays and ordinary days instead of assuming one session story explains all of them.
Let’s work through it
- Mark the reference before revealing the outcome.
- Study an early reversal hypothesis without assuming every opening move is a trap.
- Record the result and the conditions that would reject the idea.
Let’s use numbers · hypothetical example
Synthetic open 100, initial range 99–101. Price first reaches 102 then closes back below 101 and later below 99. That path fits a reversal study; a path that stays above 102 must also remain in the sample.
Easy mistakes to watch for
- Mistaken assumption: Only keeping the days that reversed.
- Changing the definition after seeing the result.
- Ignoring spread, slippage or the loss limit.
Keep in mind
This is a hypothetical study, not a signal. A chart label cannot identify institutional intentions or guarantee a result; include costs and a predefined loss limit.
Your turn
Compare ten early reversals with ten early continuations under one fixed session definition.
A quick check before we move on
What prevents hindsight in a Judas-swing study?
- Recording both early reversals and continuations from fixed session rules.
- Only keeping the days that reversed.
- Calling the first candle a trap before confirmation.
Check answer
Recording both early reversals and continuations from fixed session rules. A fair sample includes the paths that disagree with the story.
