Android and iOS app
As the number of traders in stock market are increasing, a mobile & tablet app with real time stock price and other details for a reasonable price module can be a very profitable business.
As you already have the data, we have to just develop an app for it.
In fact, I am the co-founder of an app development company, we are very much interested in developing such challenging applications and share an idea of our own.
