A worked example
With ₹1,00,000 virtual capital, a ₹2,000 planned loss budget, ₹100 entry, ₹80 stop, 50 units per lot and ₹10 costs per lot: one whole lot fits. Two lots would have a planned loss of ₹2,020.
How the calculation works
Per-lot planned loss = (entry − stop) × units per lot + costs per lot. The calculation rounds down the lots allowed by the loss budget and by available premium capital, then uses the smaller result. A zero result means even one whole lot does not fit the inputs.
What the result does not tell you
This models bought options, not option-selling margin. Stop-based sizing does not cap loss at the entered budget; the premium and costs can be lost. Charges may not scale linearly in real accounts. Verify actual contract specifications.
