Would the margin be recalculated at the time of modification?

Yes, it is recalculated and excess amount if any will be released or additional margin needed will be blocked if you change the limit price of your fresh order or cover SLTP order. A) In the above example of fresh buy Limit order where Buy Multiplier% is 25%%, if you modify limit price to 98,modify the SLTP to 96/- and limit price to 92/-. The margin amount to be recalculated as: Min (Max [{(98-92) *1000} + {100*1000}, {25%* 98000}], (98000) =Min (Max [{106000}, {24500}], (98000) =Min (106000, 98000) =Rs. 98000 The excess amount of 1000/- would be released and added in your limit. B) In the above example where Buy Multiplier % is 25%, if you modify the limit price as 101 and limit price of your cover SLTP order to 94/- margin amount would be recalculated as Min (Max [{(101-94) *1000} + {100*1000}, {25%* 101000}], (101000) =Min (Max [{107000}, {25250}], (101000) =Min (107000, 101000) =Rs. 101000 Additional amount of 3000/- would be blocked. If limits are insufficient then you will be unable to modify the order.
