Lot size calculator

Work out how many lots to open to risk exactly what you decided, not a dollar more.

Lots to open

0.20
Money at risk100.00 USD
Distance to stop5.00
Value of 1 point with 1 lot100 USD

Standard contracts: 1 lot = 100 oz of gold, 100,000 units in currencies, 1 contract in indices and BTC. Check your broker's or prop firm's specifications.

How lot size is calculated

Lots = (capital × risk %) ÷ (distance to stop × value of 1 point with 1 lot).

Gold example: a 10,000 USD account, 1% risk (100 USD) and a stop 5 USD away. With 1 lot, a 5 USD move is worth 500 USD, so you open 100 ÷ 500 = 0.20 lots.
