comparing indicator lines with strategy parameters

[Wayne Filkins 0]

I created 2 buy conditions in the strategy init function.

        self.buyCondition1 = bt.ind.CrossOver(self.kst, self.p.zeroLine)
        self.buyCondition2 = bt.ind.CrossOver(self.kst, self.p.rsignal)

self.kst is just a line in an indicator, so it's like an sma line, so this code is working for me. I use only one of these buy conditions, but have tested both and they both work. From what I read in the docs, it's better to keep this sort of thing in init() rather than next() for better performance.

So I'm trying to do a 3rd condition to test out, but it involves comparing self.kst to a strategy parameter, self.p.overSold, or self.p.overBought. This doesn't seem to work. I imagine I can get it working in next(), but my question is, is there a proper way to do this in Init() ? Should I use a parameter from kst instead, or should I just do all of this in the kst indicator file? I'm sure if I continue to mess around with it I'll get it working, but I am trying to learn to make everything run as fast as possible. This is the code I tried for the 3rd buy condition:

if self.kst <= self.p.overSold:
            self.buyCondition3 = 1
        elif self.kst >= self.p.overBought:
            self.buyCondition3 = -1
        else:
            self.buyCondition3 = 0

self.p.overBought and self.p.overSold are just 50 and -50

on the 2nd code block the indentation looks odd but it's correct in the actual project

Create line object using bt.LineNum and than you can compare it with the self.kst using bt.If.

@ab_trader Looks like the "if" was the problem. Didn't realize I had to use bt.If in init(). Used lineNum too but not sure if I had to, I'll just leave it though. Thanks!
