The problem
Most traders don’t blow up their accounts on a bad setup. They blow up on a good one they sized too big.
Between 74% and 89% of retail traders lose money. That figure has held across every platform, education level, and regulatory environment studied over three decades and across millions of accounts. The researchers isolated the variables. The setups were not the problem. The entries were not the problem. What destroyed those accounts was the decision made in the ten seconds before the buy button was pressed.
80% of day traders quit entirely within the first two years. Not because the market was unreadable. Because one oversized position started a cascade they never recovered from, financially or psychologically.
This is not a talent problem. It is a process problem. And process is fixable.
