Why are positions clubbed at scrip level for calculation of margins?
Positions are clubbed at scrip level across settlements to provide the benefit of excess margin available in positions taken in one settlement is adjusted towards positions in another settlement. It is possible that the Available margin for a position is more than the required level of margin and another position in the same scrip does not have sufficient Available margin. In this case it proves beneficial to club the positions in a scrip to provide benefit of excess margin available in a position.
