CONDITIONAL UPSIDE
Why can it look attractive?
It is simple and easy to automate. In a range or mean-reverting market, a modest pullback may close the basket, making the observed win rate and early equity curve look strong.

Martingale: Why a High Win Rate Is Not Low Risk
Martingale creates no new trading edge. It reshapes the outcome distribution: many small gains in exchange for the risk of a few very large losses.

It does not predict direction; it expands risk after a loss.
Two common forms are increasing the next position after a stopped-out trade, or keeping the losing position and adding layers as price moves further against it. The second is Martingale-style averaging.
SIMPLIFIED EXAMPLE
Exposure grows exponentially, not linearly.
100 → 200 → 400 → 800 → 1600 → 3200
- Five losses create a cumulative loss of 3,100.
- The sixth position risks 3,200—32 times the first.
- A full one-to-one win leaves only a theoretical +100.
- That excludes spread, commission, slippage, overnight financing and margin limits.
TAIL RISK
One market move can dominate the record.
A sustained trend, gap, liquidity shock, volatility expansion or slippage can exhaust margin before price reverses, amplifying drawdown and liquidation risk.
RISK-MANAGEMENT CONCLUSION
Fix the affordable loss first, then size the position from the stop distance.
Do not assess a Martingale system by win rate alone. Measure its longest losing streak, maximum position, margin usage, maximum drawdown and hard stop.
