margin money is a minimum amount in your bank/brokers account for trading stocks. itis fixed by brokers. if your account digits are not suffecient for trading, the brokers sold your holding and maintain the amount. because they show all the clients accounts are clean chit the pariticular day.
ok. thanking you.
