How to write EMA crossover automated script in gekko?

[AntiLopa19]

I am a newbie who first want to trade and backtest my ideas, however there isn't much documentation and no explanation on the things that are exists. I guess the documentation is for experts.

parameters like thresholds, persistence, up, down, long, signal are not explained - is it months? minutes? percentage? what does it means?

For example I wanted to use EMA but the only thing in the docs is:

Code:

ema 

Required parameters:

optInTimePeriod

How should I write my code when this is all the docs there is?(sorry for the frustration :] )

Anyway, I was thinking on creating a strategy on EMA crossover 7+30 with 15 minutes candles.
If you can help me get started I really appreciate it.

Thanks.
