kotak securities will give margin money on existing shares in clients dp account according to there own predined scrip margin value for your existing shares in dp. so that one can buy more shares to that amount and same must be paid before payin date i,e...T+2 days...if not payed by payin time it will attract interest which is obviously high.
and regarding schemes, they have there own margin financing types with certain amount ..but it will attract interest on monthly basis.
....better buy what you can offord to pay and have a peaceful and enjoyable trading.
