ESTIMATED POSITION SIZE
How Position Sizing Works
Position sizing estimates a position amount based on account balance, risk percentage, stop loss distance, and selected value assumptions. Actual results may vary by instrument, broker, fees, execution, and market conditions.
The Formula
Position Size = Risk Amount / (Stop Loss in Pips × Pip Value per Unit)Assumptions
Results may vary by broker, exchange, instrument, contract size, fees, and market conditions.
Example Calculation
Example inputs using a $10,000 account, 1% risk, a 50 pip stop loss, and $10 pip value:
- Calculate Risk Amount: $10,000 × 1% = $100
- Identify Pip Value: For EUR/USD, 1 Standard Lot = $10/pip
- Calculate Size: $100 / (50 pips × $10) = 0.20 Lots

Does this work for Crypto?
Yes, if you treat stop loss as price difference or points and set the value per point/unit according to your selected crypto instrument assumptions.
