Total cost for amiboker + data feed

You can get pirated/unlicensed version of Amibroker on the internet, just Google it. I would not advise though, better to buy a licensed version.

Data feed depends on what pack you choose, some people give for Rs. 500/- per month (equity n fno), some charge Rs. 800/- (eq. fno n commodity)

Amibroker Trial is enough to trade.Find pricing of Ami on its site. Datafeed costs atleast 1000 for fno, 600 for currency, 2000 for mcx. Choose between Neotradeanalytics and Globaldatafeed.

You can get realtime data feeds from Neotrade Analytics (NSE authorized data vendor ) at affordable price. Do check the website for more details.
