EMA tradingview to Gekko - mikealkeal - 10-14-2018

Hello,
How to translate tradingview Pinscript :

Code:
a = ema(b, c)

To Js for Gekko in a strategy

I found this in documentation :

Code:
method.init = function() {

  var weight = 10;

  // add the indicator to the strategy

  this.addIndicator('myema', 'EMA', weight);

}

method.check = function() {

  // use indicator results

  var ema = this.indicators.myema.result;

  // do something with macdiff

}

do I have to write

Code:
method.init = function() {

  var b = 10;

    var c = 10;

  // add the indicator to the strategy

  this.addIndicator('myema', 'EMA', b, c);

}

thanks for your help.

In Pinescript you have these params:

ema(source, length) → series

For calculation in gekko you only need one param, the source (candles) is supplied by the gekko core so you need only one param in gekko, the length.

thanks mark.sch

is it possible to change the source of Gekko?

if not, does it work with tablib?
For example

method.init = function() {
var Settings = {
Close: 10,
optInTimePeriod: 10
}

this.addTalibIndicator('myema', 'ema', Settings);
