Most people think blown accounts come from bad entries. After years in the markets, I can tell you that's rarely the real cause.

It's position sizing.

Here's the pattern I see over and over:

• Trader has a solid setup, decent win rate (50-55%)

• Trader risks 10-20% of their account on a single trade "because they're confident"

• Two or three losses in a row (completely normal, even for a good system) and the account is wrecked

A system with a 55% win rate and a 1:2 risk-reward ratio is profitable long-term. But it will still lose 3-5 trades in a row sometimes — that's just variance, not a broken strategy. If you're risking more than 1-2% of your account per trade, a normal losing streak becomes a account-ending event.

The fix is boring, and that's exactly why most people skip it:

1. Risk a fixed 1-2% of account equity per trade, no exceptions

2. Define your stop loss BEFORE you enter, not after

3. Size your position based on the stop distance, not on how confident you feel

4. Track every trade — win, loss, and the reason you took it

Confidence in a trade should change your win-rate assumptions, never your risk per trade. That's the mental shift that separates traders who survive long enough to get good from those who don't.
