If you have browsed EA marketplaces, you have seen the phrase no martingale, no grid in product descriptions, including ours. It reads like jargon. It is actually the single most important risk disclosure in the entire industry.
What martingale does
Martingale doubles (or multiplies) position size after each loss. Lose 1 lot, trade 2 lots. Lose again, trade 4. The logic: the first win recovers everything. And it does, almost always. The equity curve looks like a smooth staircase because the losses are constantly being papered over by escalating bets. The problem is the word almost. A streak of 8 losses turns a 0.1 lot starting position into a 25.6 lot monster, and streaks of 8 are a statistical certainty over enough trades. When the streak arrives, the account does not draw down. It evaporates.
What grid does
Grid systems open additional positions at fixed intervals as price moves against them, averaging into the loss and waiting for a bounce to close the basket at breakeven or better. In ranging markets this works constantly. In a strong trend, the grid keeps adding to a losing position while floating losses balloon off the books. MyFXBook pages of grid systems show the tell: tiny visible drawdown, enormous hidden floating drawdown, then one day a cliff.
Why sellers love these mechanics
Because they produce exactly what sells: months of smooth, high win-rate results. A martingale EA can show a 95% win rate honestly. The catastrophic risk is real but invisible until it happens, usually after the refund window and often after the seller has moved to a new product name. The incentives are genuinely misaligned: the mechanics that sell best are the mechanics that fail worst.
What honest risk looks like instead
Our systems size every position from a fixed risk percentage with a hard stop loss on every trade. No position ever grows because a previous one lost. The consequence is visible in our numbers: a 57% win rate on the breakout system instead of 95%, real losing months on the public track record, and drawdowns that happen on the books instead of off them. It looks less impressive in a screenshot. It is the difference between a system and a time bomb.
The one-question test
Ask any EA seller: does position size ever increase in response to a losing trade? Anything other than a flat no, in writing, is a yes.
How to detect these mechanics from the outside
Sellers rarely volunteer the label, so learn to read the fingerprints in a track record. Martingale fingerprints: win rates above 85% combined with occasional single losses many times larger than the average win; trade size sequences that escalate (0.1, 0.2, 0.4, 0.8) visible in any honest trade history; equity curves that are unnaturally smooth until a single cliff. Grid fingerprints: many positions open simultaneously in the same pair and direction at regular price intervals; a large persistent gap between balance and equity on the MyFXBook page (that gap is the floating loss the closed-trade statistics hide); drawdown statistics that look excellent while the open trades tab tells a horror story. One habit protects you from both: always check open trades and floating P&L, not just closed results. The closed-trade history of a grid system can show years of profit while the account is one trend away from margin call.
The gray zone: recovery modes and soft martingale
The market has adapted to buyer awareness, and pure martingale now hides behind gentler names: recovery mode, smart position management, adaptive sizing, drawdown compensation. The mechanics vary but the test does not: does losing ever cause the system to increase exposure, in any form, under any name? Multiplying the next trade, adding a hedge basket, widening targets to recover faster: all of it is the same underlying bet that the market must eventually turn before capital runs out. Sometimes the multiplier is small (1.3x instead of 2x), which merely slows the arithmetic of ruin rather than repealing it. Our systems answer the test with an unconditional no: every position is sized from current equity and stop distance alone, with no memory of whether the previous trade won or lost. That statement is in writing, in the documentation, and verifiable in the live trade history, where the position sizes only drift with account equity and never spike after losses. Demand the same three layers (statement, documentation, verifiable history) from anyone who wants four figures for their software.
