Inconsistency is the major flaw in the system. Not only this system, but any AFL based trading. 1 year u will get 4K+ points and other years around 500 points. Reason for this is that the parameters on which the indicators are generated are inconsistent over a period of time.
Solution is to trade using atleast 2 trading systems. Instead of trading with 2 lots in one system. It is better to trade with 1 lot in each one. That way if one system is going in loss the other one may fill the gap. Caveat, Both the systems may give loss in some months. But it is very rare. I would like to suggest another system to couple with Super trend , if it is not going to disturb the flow of the thread.
