The Geek added the TradeShark hedge option to the latest version of the Geeks Toy trading software. I have made great use of this over the last few days and can report that it works perfectly. A definite plus point for tennis traders.
Please note if you are using version 1.1h beta then you will experience problems with the hedge column jumping from side to side randomly. This was a bug which the Geek fixed very quickly and the version you need is 1.1i beta.
