If you want open demat account for share market trading, Sharekhan is good available option.
They do provide training related to trading for beginers of share market.
Sharekhan trading software TradeTiger account is very esay to use, response is quick. It is a single platform for multiple exchange, BSE & NSE.
One can easily do online transfer of funds. You can see all details on your PC screen while trading. You can trade from your home with sharekhan. They provide free telephone assistance while trading day to day.
Only issue that I noticed with sharekhan is that their brokerage charges are bit higher specially for intraday trading compared to other service provider in market.
You have to negotiate a lot to get discount on brokerage.
