Every backtest includes costs. Set your brokerage per order or per lot, or pick 9 rupees a lot with one click.

Slippage is added to every order: a quarter of a percent of the price by default.

Taxes and exchange charges are included too, at today's rates.

Choose how fills are priced: standard, or exact levels. The note underneath explains the difference.

And the lot size: as it was on each day, today's lot size for every day, or a fixed number.

Every number in the results is after these costs.
