I have a demat account with Icici direct. Although the service is very nice but we have to maintain a minimum balance of 5000 (from 1st July it is 10000)and this is very frustating. Icici gives the facility of zero balance to those opening demat account with SMC, Kotak etc. But those opening demat with ICICI are not give this benefit. What a big flaw....At least ICICI should give zero balance facility to its customer who are having demat and trading account with them..
