backtest results calculate not properly ?

[askmike]

Could you explain on example what does mean - persistence?

This is not from Gekko, but from some strategies. The persistance of the example MACD strategy is described here: https://gekko.wizb.it/docs/strategies/in....html#MACD

Start balance > 100. Why?

Because you most likely configured Gekko to start out with some asset, when the backtest started the value of those was different from when it did the first roundtrip.

It sounds like don't really understand Gekko and how it runs strategies. I advice to watch this video: https://www.youtube.com/watch?v=PKIxZ-Qaphk
