Risk dollar amount

The Risk dollar amount method sizes the position so that your maximum loss (if the stop loss is hit) equals a fixed dollar amount.

How it's calculated

• Risk per share = |entry price − stop price|
• Quantity = risk dollar amount ÷ risk per share

Example

• quantity = 100 ($100 max loss), entry = $100, stop = $90
• Risk per share = $10
• 100 ÷ 10 = 10 shares

Configure this in your strategy under Quantity calculation method → Risk dollar amount. A stop loss is required. Or override it in a webhook by sending quantityType=risk_dollar_amount with quantity as the max dollar risk and include stopLoss.stopPrice in the signal.
