Potentially Useful Strategy (Inverse Fisher Transform RSI)

Code:
var strat = {};

var traded = false;

var IFTRSI = require('./indicators/IFTRSI.js');

strat.init = function() {

    var iftrsiParameters = {rsiInterval: 14, wmaLength: 8};

    this.addIndicator('iftrsi', 'IFTRSI', iftrsiParameters);

    

}

strat.update = function(candle) {

    this.indicators.iftrsi.update(candle);

   

}

strat.check = function(candle) {

    var iftResult = this.indicators.iftrsi.result;



if ( traded == false && iftResult < -0.5 ){

    this.advice('long')

    traded = true;

    console.log(iftResult);

}else if(traded == true && iftResult > 0.5 ){

    this.advice('short')

    console.log(iftResult);

    traded = false;

}

}
