Position Sizing After a Loss
Never oversize a trade again. After a drawdown, size down: enter your account, risk percentage, and stop-loss to get a disciplined position size that keeps any single trade from setting you back.

Pro Tip
Most professional traders risk 0.5–1% per trade. If you're risking more than 2%, you're one bad streak away from a serious drawdown. Consistency beats size.
Why Position Sizing Matters
The #1 Account Killer: Oversizing
Most blown accounts aren't killed by bad entries — they're killed by positions that are too large. When you risk 5% or more per trade, just 4 consecutive losses wipe out 20% of your account. At 1% risk, those same 4 losses only cost 4%.
The Break-Even Math Problem
After a 10% drawdown, you need an 11% gain just to break even. After 20%, you need 25%. After 50%, you need 100%. The deeper the hole, the harder it is to climb out. Proper position sizing keeps drawdowns shallow and survivable.
The Professional Standard
Hedge funds and prop desks typically risk 0.25–1% per trade. They survive because they can absorb 20+ consecutive losses without significant account damage. Your position size should be determined by your stop-loss, not by how confident you feel.
