Adding custom trading indicator to own strategy

[SuperUserek]

Hi there, i am very new to Gekko. As a programmer (hobbyist) i was going to make my own bot till i have found Gekko, but lack of documentation and js (yet - so far i know basics so i will get on it quick) decided to use it and apply my trading skills. And make my own stategies with as less loss as possible.

But to start of i need some of you to clarify some things for me.

There is simple strategy config in js to be customised.

Code:

// Let's create our own strategy
var strat = {};

// Prepare everything our strat needs
strat.init = function() {
 // your code!
}

// What happens on every new candle?
strat.update = function(candle) {
 // your code!
}

// For debugging purposes.
strat.log = function() {
 // your code!
}

// Based on the newly calculated
// information, check if we should
// update or not.
strat.check = function(candle) {
 // your code!
}

// Optional for executing code
// after completion of a backtest.
// This block will not execute in
// live use as a live gekko is
// never ending.
strat.end = function() {
 // your code!
}

module.exports = strat;

I have had a look inside some strategies. And still doesnt understand where did you get variables and results from your own strategy.

For instance i would like to use Tulib and use some of indicators for example BBands.

So to code above as i have found on your webside to use tulib indicators example as followes

Code:

method.init = function() {
 var customMACDSettings = {
   optInFastPeriod: 10,
   optInSlowPeriod: 21,
   optInSignalPeriod: 9
 }

 // add the indicator to the strategy
 this.addTulipIndicator('mymacd', 'macd', customMACDSettings);
}

method.check = function() {
 // use indicator results
 var result = this.tulipIndicators.mymacd.result;
 var macddiff = result['macd'] - result['macdSignal'];

 // do something with macdiff
}

I have put this together for Bbands indicator but got some questions about it can you have a look on the code?

Code:

// Let's create our own strategy
var custommethod = {};
// ---------------------------- INIT
custommethod.init = function() {
 var customBBandsParams = {
 //I THINK this should be taken from: https://gekko.wizb.it/docs/strategies/tulip_indicators.html
optInTimePeriod: 20,
optInNbStdDevs: 2,
}
//this.addTulipIndicator('FUNCNAME,INDICNAME,PARAMSIFNEEDED')? <-- IS THIS RIGHT THINKING?
this.addTulipIndicator('mybbands', 'bbands', customBBandsParams);
}


// What happens on every new candle?
custommethod.update = function(candle) {
 // LETS SKIP THAT FOR NOW
 // CHECKING PRICE OR SOMETHING ELSE
}

// For debugging purposes.
custommethod.log = function() {
 // LETS SKIP THAT FOR NOW
}

custommethod.check = function(candle) {
 // your code!
 var result = this.tulipIndicators.mybbands.result;
 var resultofbbands = result['bbands'];
 //==============??????????????? HOW DO I GET DETAILS ABOUT IT TO CONSOLE?
 //==============??????????????? WHERE DID YOU GET LETS SAY 3 LINES top middle bottom one printed out to actually print numbers of possition of those bands??
 
 log.debug('RESULT FROM INDICATOR BBANDS');
 log.debug(result);
 log.debug('RESULT OF BBANDS');
 log.debug(resultofbbands);
 
}
/////////////////EXAMPLE WITH MACD FROM JS FILES
//method.check = function() {
//  // use indicator results
//  QUESTION WHERE DID YOU GOT THOSE VARIABLES SUCH AS RESULT MACD and MACDSIGNAL?
//  ANY WEBSITE / MANUAL ???
//  var macddiff = result['macd'] - result['macdSignal'];
//  var result = this.tulipIndicators.mymacd.result;
//
//  // do something with macdiff
//}

// Optional for executing code
// after completion of a backtest.
// This block will not execute in
// live use as a live gekko is
// never ending.
custommethod.end = function() {
 // your code!
}

module.exports = custommethod;

This is my first attempt and i have loads of questions

Thanks for looking, hope you can clarify my questions and make it brighter for me and others.

Hi
The config.js is only used by the CLI-cmd version of gekko.
The --ui version is fully configurable from within the ui.

for tulip indicators you find docu here:
https://gekko.wizb.it/docs/strategies/tu...ators.html

there is also strategies that already using tulip lib for ease...
