Feed method in next() with self.data.Close one by one in each iteration, untill it returns data

[traderblakeq]

*have uploaded new example of Code, a simple example...

I have a peak finder method "detect_peaks_gaussian"... My goal is to feed it with self.data.Close one by one after "if crossover(...)" untill it returns peaks...

I have tried that in above picture, but I can feel this is not the right way ? - Is there a better way.

Any advise is appreciated :)
