Do any one using HDFC demate account for trading?

HI....opening a demat account always depend on your needs....first question is whether you are regular investor or part time , in case of part time nothing matters but if you are regular then you have to trace the market and in that case DEMAT ACCOUNTS BY BANKS are not easy becouse they have lack of facility and if you are trading your self then you have to keep number of pwords and keep changing them time to time...moreover if you forget any thing then it's frustrate..so final word it's not ok to open demat account with ANY bank.
