Hi @Paul and @samsampop

Sorry, I haven’t  been very active recently. I revisited this code and it seems to have some potential. With minimal optimisation it still produces a good back test.  It breaks all the rules, too many parameters, too little historic data etc. But I’m still interested in this kind of automatic scalping strategies.  Any ideas would be welcome. The custom indicator (Perfect Trend Filter) is made by @aleale from his website.
