Thank you but again I'm facing another error:

Code:

This seems more tricky, cause it is not well explained.
Could you please help me another time?

Thank you!

my code:

Code:

var log = require('../core/log.js');

var strat = {};

strat.init = function(){
// Add Ichimoku Indicator
this.addIndicator('ichimoku', 'ICHIMOKU');
}

strat.check = function(){
var ichimoku = this.indicators.ichimoku;

//ICHIMOKU INDICATOR
log.debug('ICHIMOKU INDICATOR');
log.debug('tenkan:', ichimoku.tenkan);
log.debug('kijun:', ichimoku.kijun);
log.debug('senkouSpanA:', ichimoku.senkouSpanA);
log.debug('senkouSpanB :', ichimoku.senkouSpanB );
log.debug('------------------------------------------');

}

Did you write this indicator?

I would install the npm version Fizcko mentioned. Then just add the following line to the beginning of your strat near the "var log" line.

Code:

var Ichimoku = require("ichimoku");

then add this to your strat.init().

Code:

this.ichimoku = new Ichimoku({
   conversionPeriod : this.settings.conversionPeriod,
   basePeriod       : this.settings.basePeriod,
   spanPeriod       : this.settings.spanPeriod,
   displacement     : this.settings.displacement,
   values           : []
 });

where 'this.settings.XXX' refers to XXX setting in your toml file.

I have my version set up slightly different now, but that should get you going.

has anyone succeded to implement ichimoku into gekko?
