Why Position Sizing Matters
1-2%
Professional standard
Most institutional traders risk no more than 1-2% per trade, regardless of conviction.
6-8%
Portfolio stop threshold
If you lose 6-8% of your total account in a month, most pros suggest stopping and reassessing.
50 losses
Survivability at 1% risk
Risking 1% per trade, you could lose 50 consecutive trades and still have half your account.
