Martingale

এই আইনি পৃষ্ঠাটি শুধুমাত্র ইংরেজিতে উপলব্ধ।

Martingale doubles (or otherwise escalates) size after each loss, so the eventual win recovers everything plus a small profit. The equity curve it produces looks eerily smooth — until a streak arrives that the account cannot double through.

Variants (grid trading, "recovery zones", partial martingale) soften the escalation but keep the shape: many small wins funded by rare, potentially catastrophic losses. Recognizing this shape in a track record is a core skill of EA evaluation.
