How is the initial margin (IM) on open position maintained?
The same margin % applicable for orders will be levied at position level also. Position level margin is arrived at by applying the IM% on the value of net open position. For example, you have open buy position in NCD-FUT-RBRRS4KTM-20-Mar-2006 for 10 MT @ 6850 per quintal and IM % for RBRRS4KTM is 25% and multiplier is 10. In that case, margin at position level would be 685000 * 25% = 171250/-. Moreover, benefit of calendar spread margin may also be available to you in case of spread position.
