Is there is any requirement for maintaining minimum allocation (balance) in my trading/investment account?
No. There is no requirement of maintaining a minimum allocation in your trading/investment account. However, you will have to maintain the minimum balance in your bank account as stipulated by your bank. In case the minimum amount is not maintained in your bank account, it may so happen that an instruction placed by you in the payment gateway facility is not honoured by your bank. Alternatively, your bank may levy charges on you for not maintaining the minimum balance. Please obtain complete information in this regard from your bank.
