Max Consecutive Losses
Definition
Max consecutive losses is the longest streak of losing trades in a row. Understanding this metric is critical for position sizing because it determines the worst-case drawdown from a string of losses.
Every trading strategy will experience losing streaks. Even a strategy with a 60% win rate will statistically see 6-8 consecutive losses over a sample of 100 trades. A 50% win rate strategy can easily see 10+ consecutive losses. This is pure probability, not a sign of a broken strategy.
For prop traders, the max consecutive losses metric directly impacts position sizing decisions. If you risk 2% per trade and experience 8 consecutive losses, that's a 16% drawdown — enough to violate most prop firm rules. This is why conservative position sizing (0.5-1% risk) is essential for prop trading.
PropJournal tracks your max consecutive losses and uses Monte Carlo simulation to estimate the probability of various losing streaks based on your historical performance. This helps you size positions to survive the worst-case scenario while still having a realistic chance of hitting your profit target.
