Certainly financial signals are to a much lesser extent applicable to sports markets. But there are some basic elements that can help, such as support lines and volume.
But such an application would be very useful to see the market better, especially for cricket and tennis, which are the best sports for trading.It would also be useful to generate strategies, many repetitive patterns can be observed by analyzing the graphs.
And on top of that, it would be a unique product, which does not exist at the moment.The current graphics from betfair are absolutely pathetic.
I think it would be a mandatory tool for every professional or semi-professional trader, just like the ladder interface.
