Example use cases

Example prompt

When to prefer

Use this endpoint when you need fast, deterministic position sizing calculations based on fixed-risk methodology — especially for equities or any instrument where you know the entry price and stop loss. Preferred over manual calculation or general-purpose math tools when you need the full risk summary (shares, position value, max loss, 2R target) in a single call.

Side effects

stop_loss >= entry_price returns validation error
risk_per_trade > 1.0 or negative values return 400 bad request
account_size of zero or negative triggers error
missing required fields return 422 unprocessable entity
network timeout or service unavailability returns 5xx
