New research published: RP-004
We tested whether entering a contrarian trade at retail positioning extremes produces a systematic price path advantage.
75,864 SSI extreme events. A random baseline of 7,696 entries as the control. Every z-score magnitude, every session, every era from 2014 to 2023.
The result: the contrarian price path advantage is zero. MAE-first percentage is 50.3% for SSI extremes vs 49.9% for random entries. A coin flip.
Deeper extremes don’t help. Trailing volatility at entry doesn’t help (that finding required a decontamination exercise — the original proxy was encoding the outcome it was supposed to predict).
But SSI extremes do predict something: volatility. Deeper positioning extremes produce larger price swings in both directions — more movement, not more directionality. The crowd reaching maximum conviction tells you something is happening. It does not tell you which way.

This is the fourth report in the FXE Research series. All findings — including the nulls — are published with the same rigor and prominence.​​​​​​​​​​​​​​​​

Price Path Dynamics After Retail Positioning Extremes Forward excursion analysis of 75,864 SSI extreme events. The null holds. One asymmetry survives. And a forward-looking signal points somewhere unexpected.
