Why isn't there a EMA strategy?

[mutenroch]

This is a question for askmike, but if anyone else can answer then please do:

I am fairly new to Gekko and am looking at the strategies available, the one that I am interested in is the EMA strategy after having read about it from Goomboo's posts from your recommendation.  It is also available on many of the online crypto websites, (GDAX cryptowat.ch) where you can select it from the menu and the EMA will appear along with the candles on the main chart.

Whilst I have been into cryptocurrencies for about a year, I was going to write a bot myself being a software developer but someone sent me a link to yours which I am using and perhaps modifying and creating it myself, however before I do, I thought there must be a reason why you create it yourself?

The EMA strategy used by Goomboo that you are talking about is the DEMA (double EMA)! It is triggered when the shorter EMA crosses the long.. therefore both EMAs are needed, therefore is is called here DEMA...
The EMA strategy is just a trend indicator and does not provide trading signals by itself...
Also, don't hesitate to collaborate on github instead of just doing your own bot! The more we are, the better gekko will be (i'm talking for myself, and not in the name of the main dev: askmike)..

hi ktk,

would you know why the parameters for EMA are thresholds and not number of periods or candles?
