When Tennis Profits launched a couple of years ago, it was the intention to merge TradeShark Tennis with it. Since the launch it has become clear that the two services suit very different customers. TradeShark will remain separate.
The TradeShark Trading Course is a one time payment for lifetime access and lifetime support. Tennis Profits has some of the TradeShark Course along with a stats database to research matches. There is a live section that allows you to follow multiple matches with stats on just 1 page. There are also streaming graphs of serve stats during matches. Tennis Profits is a monthly subscription.
The Trading Tips service was never going to be included in Tennis Profits.
Both service are excellent and obviously the trading help and support is given by me for both sites.
