Gaz, you can do that in a min, just hack RSX Swinger (point).mql4 as described below:
Find original code:
PHP Code:
IsBuy = (rsx1 <= Buy_Level && rsx0 > Buy_Level);
IsSell = (rsx1 >= Sell_Level && rsx0 < Sell_Level);
IsCloseBought = (rsx0 < Exit_Buy_Level);
IsCloseSold = (rsx0 > Exit_Sell_Level);
Reverse IsBuy <--> IsSell, IsCloseBought <--> IsCloseSold. Swap only the names before equal signs not the whole lines.
PHP Code:
IsSell = (rsx1 <= Buy_Level && rsx0 > Buy_Level);
IsBuy = (rsx1 >= Sell_Level && rsx0 < Sell_Level);
IsCloseSold = (rsx0 < Exit_Buy_Level);
IsCloseBought = (rsx0 > Exit_Sell_Level);
Now remember that Buy_Level and Sell_Level are opposite now. In case you want to change Buy_Level then change Sell_Level instead.

I could just swap the code for you, but I think this is nice experience for you.
