I need to backtest on nifty and stocks for 5 years, How can i do that? Also plz tell when are we going to go fully automated for algo trading? I need it on priority basis. thanks
If you want to backtest on much larger amounts of data, suggest you to a professional data vendor and a tool like amibroker. We at Zerodha have a partnership with Neotrade, send them an email and give your Zerodha client ID. They will give you a discount.
