PSAR indicator and multiple timeframes

[borodiliz]

Thanks @backtrader. That will cover most cases. Maybe the SAREXT indicator should also be added?

In my case I'm working with a very large datasheet so to avoid performance issues I've coded something like:

    def next(self):
        self.psar0._lookback = min(100, len(self.data0))

so I have a "dynamic" _lookback from 1 to 100

And why 100?... newbie here! just by observation, it seems to be a good value to calculate a real ParabolicSAR value.
