Risk Management Tip: Most professional traders risk no more than 1-2% of their account balance per trade. This protects against drawdown sequences and preserves capital for future opportunities.
Why Position Sizing Matters
Position sizing is arguably the most important aspect of risk management. It determines how much capital you put at risk on a single trade and directly affects how long your account can survive a losing streak.
A common rule of thumb is to risk no more than 1-2% of your account balance on any single trade. This means that even a run of 10 consecutive losing trades would only reduce your account by 10-20%, leaving you with enough capital to recover.
How to Calculate Position Size
The formula is straightforward: divide the amount you are willing to risk (account balance multiplied by risk percentage) by the distance to your stop loss in monetary terms. The calculator above handles this automatically for any currency pair and account currency.
Risk Management Tips
- Keep risk per trade consistent (1-2% of account balance)
- Always set a stop loss before entering a trade
- Adjust position size based on stop loss distance, not the other way around
- Factor in correlation when holding multiple positions in related pairs
