While going through the unanswered questions, I cam across this question "https://money.stackexchange.com/questions/14784/does-indias-national-spot-exchange-support-web-based-trading-for-retail-investo"
The National Spot Exchange has since gone bankrupt [August 2013] and hence the question is irrelevant. How should we go about this and other such question that may have answers but the questions themselves are irrelevant.
