Hello,
You are doing great. I wonder, with the infrastructure you have, you could provide many chargeable services. For example, sms/mail alerts for stock price/volume movements would be one that most people would be glad to pay for. Now the charges are high in the market. From Rs.900/- upwards (traderscockpit.com). If you could provide such alerts at a cheaper rate, people like me would would definitely buy.
Thanks
