how profit / loss calculated in future ( commodity ) trading after disposed off a contract ?
you seemed to be so much confused with trading commodities. may i know who is your broker coz he should be one educating you on these matter.
Anyways if by "disposed off contract" you mean expired contract than you must get closing rate of that instrument from bhav copy at mcx, and I guess it will also reflect in your contract notes. Just do the basic plus/minus with the two figures and you'll be fine. Still confused than share your contract notes.
Hope it helps.
