Futures Trading

When is the obligation amount debited or credited in my bank account?

All futures obligation is settled by exchange on T+1 basis. This means that any obligation arising out of transactions in futures or EOD MTM on day (t) is settled on an immediate next trading day. This further means that if you have a debit obligation on day (t), the payment will have to be made on day (t) itself. Whereas If you have a credit obligation, amount would be credited in your account on t+1 day. If t+1 days is holiday, credit would be given on subsequent day.
