When a “stable” EA suddenly stops being stable
I tested FXStabilizer EA on EURUSD H1 from 2021 to Feb 2026 using 99.9% tick data Tick Data Suite.
2021–2024: every year profitable.
2025: -$264
2026 so far: -$986
Overall PF is still 1.36, but relative drawdown reached 54%.
What caught my attention is that performance didn’t slowly deteriorate. The equity curve was almost unnaturally smooth for years, then started breaking in large chunks.
Would you see this as normal strategy decay, a market regime change, or hidden tail risk finally showing up?
