Position size connects your risk rule with the actual distance between entry and stop. Two trades with the same monetary risk can require very different sizes when their stop distances differ.

Generic formula
A general approximation is: risk amount ÷ (stop distance × value per point/pip/unit). The result must then respect the instrument’s own rules: whole contracts, minimum lot size, permitted fractions and costs.
What point, pip or unit value means
The value depends on the market and instrument. Futures contracts have defined point values; Forex pip value depends on pair and position size; stocks are usually tied directly to share count; crypto depends on the product and quotation convention.
Do not forget costs and slippage
The calculator provides a mathematical reference. Commissions, spread, slippage, gaps or a fill beyond the theoretical stop can make the realised loss larger. That is why planned risk and actual executed risk should be compared afterwards.
How to use it with your journal
Recording size, initial stop, planned risk and actual risk can reveal whether exposure tends to increase precisely on your worst-executed trades or in specific markets.
