Keeping risk consistent on every trade is one of the keys to trading success; AI Strategy Studio works directly with AI Trading Journal to calculate your position size simply and in real time. You no longer need a calculator or pip-value tables for each symbol; set your risk percentage or dollar amount once and the platform automatically calculates the exact position size (Lots) on every trade from the distance between entry and stop loss.

Example: your account balance is $10,000 and you set risk per trade to 1% ($100). If your first trade on EURUSD has a 20 pips stop loss, the studio calculates 0.50 lots; if your next trade has a 50 pips stop loss, it automatically lowers the size to 0.20 lots so your risk stays at $100.

Set risk per trade in the Build tab

  1. In the Build tab, click the dashed + risk per trade button (or the risk link at the end of the strategy sentence) to open the risk panel.

  2. Select one of the risk percentage preset chips (0.5%, 1%, 1.5% or 2%) or enter a custom percentage or dollar amount.

  3. Choose your account balance source (Balance source): pick one of your connected accounts in AI Trading Journal (a real account connected with ForecastFollow or a Virtual Account) so the live balance is read automatically, or type a fixed balance amount.
