Hello,

I was reading through the manual about setting commission in Asset*.csv and TMF, but unable to come up with a solution for IBKR India commission model. I'm trading option contracts (25 per lot) just like stocks (buy low / sell high). I'd like to set commission per trade at 20 Rupees (INR). When I set 20 in Asset*.csv Zorro calculates the commission per contract ( 25 * 20 = 500).

So in short when I buy a Option Contract at INR 100, the cash I need would be:

100 * 25 (LotAmount) + 20 = 2520.

Assuming I make a profit trading this option and sell the option at 125, that trade would require another 20 INR as commission.

125 * 25 - 20 = INR 3,105

So profit should be = INR 3105 - INR 2520 = INR 585.

In other words, Profit = (125 - 100 ) * 25 - 20 ( comm buy to open trade) - 20 (comm sell to close) = 585.

Any help is greatly appreciated.

Thanks
