Losses in a Row: What Every Trader Needs to Understand About Drawdowns

By Michael Nauss, CMT
In trading, losses in a row aren’t the exception — they’re a statistical certainty. Yet, too many traders get shaken out after 3-5 losing trades, thinking the system is broken.
“I’ve got a 50% win rate — shouldn’t I win every other trade?”
No. That’s not how probability works. And believing that’s how it works is the fastest way to blow up a good strategy.
📊 Key Insight From This Week's Chart:
In a 50-trade sample with a 50% win rate, there’s a:
✅ 100% chance of 2 losses in a row
⚠️ 78% chance of 5 losses in a row
🚨 30% chance of 7 losses in a row
❗ 5% chance of 10 losses in a row
Let that sink in. You’re almost guaranteed to experience long losing streaks — even with great systems.
🧠 What This Means for You:
You will have losing streaks — plan for them.
Your equity curve won’t look like a metronome — it’ll lurch.
The worst time to quit a strategy is during a statistically normal drawdown.
Your sizing has to be light enough to survive that drawdown.
This is true whether you're trading your own strategy or using systems from StatsEdgeTrading.com
🔁 Example:
A strategy with a 60% win rate and 2:1 reward-to-risk is fantastic. But you'll still need the guts to push the button again after losing $2,500 across five trades.
And that’s what separates pro traders from hobbyists: emotional endurance through statistically normal rough patches.
