Gekko works great but I have some questions

@0mathew0 I don't understand what you mean by warm-up on a candle, please will you explain?  

Thanks! :-)

For example a 26 period SMA will required 26 candle updates in order to have enough data. So the idea is that "update" should update all your indicator values and states etc, then "check" can query them to generate buy/sell signals.
