Position sizing: how much to trade
Position sizing determines how much of your capital you risk on a single trade. It is one of the most important factors in long-term survival and consistency.
Repeatable process
Using consistent sizing rules prevents emotional overtrading or revenge trading.
Manage drawdowns
Smaller losses are easier to recover from, allowing steady growth over time.
The key concept
Position size should be based on risk, not confidence.
How traders size positions
Most traders define a fixed percentage of their account to risk per trade. For example, risking 1–2% means even a series of losses will not destroy the account.
Total capital
Your account size determines how much absolute value is at risk. Larger accounts still follow percentage-based risk rules.
Invalidation level
The distance between entry and stop-loss affects position size. Wider stops require smaller position sizes to maintain the same risk.
Common mistakes
Beginners often increase position size after losses, trade too large during high confidence, or ignore stop-loss placement when sizing positions. These mistakes increase risk exponentially.
Simple rule
If losing the trade would significantly affect your account or emotions, the position size is too large.
Practical approach
Decide your risk per trade first, then calculate position size based on stop-loss distance. Never reverse this process by choosing size first and adjusting risk later.
