@run-out It looks good, thank you.

@vladisld How can I access the full line data of observer after cerebro.run()?

Seems the nan count same to the non nan count, in other words, the nan is a half of the observer.array.

@run-out But why my analyzers are empty? I had run strategies = cerebro.run().

@run-out It looks good, thank you.

@run-out I just need to get the length of data in __int__, not in next.

The built-in plotting style not good for me, I want to draw with plotly. But how can I export the trade record, cash/value record, etc..?

@run-out I need to compute the mean so I had to do that in init

So, what's the solution?

In fact, I need to do a numpy.abs() on the result of self.datas[0].close - self.datas[0].open.
