I would assume that the actual exchange characteristics are similar between wsex and real futures trading - neither market is entirely predictable. As such, strategies are based on the movement of the contract price. I suppose that with historical prices you can test strategies such as "buy at $50, sell at $100 or $20", or "buy after a price drop of 20%". Whatever the system you think up, you would have a chance to test it on real data. I am sure that there isn't a "Holy Grail" of strategies, but probably hundreds with varying risk and profitability.
Based on the above, I am trying to find reasons why these would not work. If there are profitable systems out there, you will have the resources to find them. Can it be that there aren’t any profitable systems because of the unpredictable markets? I suppose, but if the wsex exchange is similar to real futures exchanges, and if these tools work in real futures trading, then they should work at wsex.
In any event, this seems very interesting. I am hoping to hear what others think.
