Position Sizing from Risk Percentage and Stop Distance

Summary

The document explains a basic position-sizing calculation: derive trade volume from a chosen risk percentage and the distance to the stop loss. It says the method is intended to work across security types. The calculation therefore connects the amount at risk per trade with how far the stop is placed, yielding a lot size for the proposed trade.

The result is not constrained by the account’s maximum tradable volume, which depends on account size and leverage. Traders must check that separate limit before placing a trade; the calculated size alone does not confirm that the account can support it. The document supplies no formula, worked example, assumptions about contract specifications, or discussion of slippage and gaps, so it is a high-level description rather than a complete sizing procedure.

Key ideas

• Trade volume is calculated from a risk percentage and stop-loss distance.
• The described sizing approach is intended to apply across security types.
• The calculated lot size does not account for account-specific volume limits from balance and leverage.
• The document gives no formula or examples and does not discuss execution risks such as slippage.
