I have been with HDFC for around more than 6 six year. There are a lot of advantage to join HDFC securities.
First, its website is very user friendly and simple to understand. Second one you will receive the mail on a daily basis and what you have in your account and what you sell today.
Third its customer care support is quite good, you can book the transaction on call without any charges.
Fourth, once the transaction done, amount will be credited to your account in T+2 days automatically.
All the things whether you want to take SIP, 5 year FD within one application thats makes you feel good.
Yeah brokerage charges a little bit higher but as per quality and security features its quite genuine.
