My personal experience with Zerodha is that Zerodha attracts the college student and other newbies with low pricing. That's all they have to it.. once you dig in more details and find out that you have lost, only then you would realise the big mistake you made by sticking with zerodha.
Bracket order has been introduced recently in Kite.. after several months. .. I doubt that a basic technology (offerered by Sharekhan since a long time) to be brought by Zerodha takes such a long time.
There are data issues in intraday and basically I understood that intraday trades will often remain unexecuted, executed later, etc. Placing a market order with a discount broker can be disastrous.
When you speak to the Marketing team/ Account Opening Team, they say all facilities are available. Autotrading is part of the facility and thats why so many are opening their account with Zerodha; however, once the account is opened and their meter is running... they say that the best that can be offered to retail trader is semi automated trading along with additional monthly costs (Rs 500 PER MONTH for a pi-bridge plugin) and Rs 2000 PER MONTH for kite API enabling. The rest you have to figure out yourself, they will only enable it for you at their end.
Summary is .. zerodha is like a "TEST" trading account.. but for serious trading over Rs 2 lacs capital .. it is a Strict NO NO...
Thank you.
