The stop goes under the base, not the bottom of the whole move

The most common sizing mistake is anchoring the stop to the absolute low of the last twelve bars. On a setup that has already climbed, that low is far below the breakout, and your risk is five times what it should be.

The correct stop goes under the base of the setup itself. If you are long an ascending triangle, the stop goes under the triangle floor, not under the swing low from three days ago. The triangle floor is the level that proves your read wrong. A break below it means the setup failed, and you are out.

This matters because risk determines everything. A five tick stop lets you size for survival. A twenty five tick stop forces you to trade a fraction of the size, and your edge cannot overcome the spread of commissions over that many trades.

The simulator bot places tight stops under the base, not the whole move. Watch how it does it, then copy the habit.
