Cnc is cash and carry . You are buying and keeping it. Basically its delivery. Margin on the other hand is for intra day trading where for huge amts you need to pitch in a bit and the bank will pitch the rest and it will be squared off at the end of the day. If its heading towards a loss you can always convert it into delivery . Beginners are usually advised to stay away from intra day trading .
before the end of the day if i wont sell intra day shares then bank will forcibly sell those shares at current price?
Thanks in advance
