The helper.js includes a collection of modules that I find myself creating each time I make a strategy.
You need to add the helper.js file to the root of your Gekko folder, then add var helper = require('../helper.js'); to the top of your strategy.
"A trailing stop order sets the stop price at a fixed amount below the market price with an attached "trailing" amount. As the market price rises, the stop price rises by the trail amount, but if the stock price falls, the stop loss price doesn't change, and a market order is submitted when the stop price is hit."
We initialize our trailing stop loss in our init function in our strategy like so:
strat.init = function() {
this.stopLoss = helper.trailingStopLoss();
.....We create a trailing stop anytime we make a purchase according to the various indicators we set up in our strategy.
this.stopLoss.create(somePercentage, currentPrice);We destroy our trailing stop after any time we call this.advice('short')
this.stopLoss.destroy();We must also check on each candle to see if our trailing stop loss has triggered, we can do it like so:
strat.check = function(candle) {
const currentPrice = candle.close;
if(this.stopLoss.isTriggered(currentPrice)) {
this.advice('short');
this.stopLoss.destroy();
} else {
this.stopLoss.update(currentPrice);
}
.....We would place the above code in our check function in our strategy.
