  Preload History
Posted by: 0mathew0 - 02-07-2018, 10:10 PM - Forum: Technical Discussion - Replies (4)

Hi all,

whats the right process to let gekko livetrader use as much local history (from an import) as possible? I have a strat that uses a very slow sma and it would take days to wait until it fetches enough data to start.



Exclamation Need help I don't know if my bot is working UI

  Is BTC markets supported?
Posted by: Storm-E - 02-07-2018, 11:51 AM - Forum: Other exchanges - Replies (2)

Before you say read the site. Smile

It's in the list of supported exchanges but there was a bit of a cryptic comment about some errors with it.
and I'm not sure if it was fixed.

I'm in Australia and have a preference for BTC but don't want to point Gekko and find out too late that doesn't work. Sad

Thanks for the advice!

  Access PerformanceAnalyzer Statistics in Plugins
Posted by: rkingy - 02-07-2018, 07:13 AM - Forum: Technical Discussion - Replies (4)

I've changed my setup recently from using the UI to running Command Line Gekko as a proper service on my linux box.. which has added benefits of starting and stopping many different strategies, but on the downside I've found the reporting really average.

I've been scrolling through a log file looking for the Buy and Sell to figure out whats going on.
Surely there is a better way? Maybe I've missed something??

Anyway I've enabled the Pushover app plugin which seems to be good but very limited info...

My question is can I access the PerformanceAnalyser plugin and statistics functions from within the Pushover plugin?

Ideally every time I go long I want just a message saying that I've gone long at price X.
And every time I go short it should tell me the sell price, my current trade profit/loss and the total portfolio profit/loss since starting the strategy. 

Keen to get some thoughts on the best approach here before I start coding.. as it seems difficult to easily test this without actually starting the bot and hoping for the best.


  Interact with the UI
Posted by: tommiehansen - 02-06-2018, 06:25 PM - Forum: Technical Discussion - Replies (6)

Any way to post things to ui; any way to hook into it and perform stuff?

I'm thinking like this (this will not work, but example...):

var strat = {

 end: function()
   alert('Finished in in X time');


This could further be expanded and do more useful things such as this:

var strat = {

  say: function( text )
    if ('speechSynthesis' in window)
      let utterance = new SpeechSynthesisUtterance(text);
      utterance.lang = 'en-US';

  end: function()
    this.say('Finished in X time');

} // strat{}

Codepen demo:

Input something into input and press return.
If your browser has support for speechSynthisis it will say what you wrote.

  Gekko with malware spotted in the wild
Posted by: askmike - 02-06-2018, 06:06 AM - Forum: Announcements - Replies (2)

Gekko is a free and open source tool, it doesn't cost any money to download and you don't need to register anywhere.

The only official way of downloading it is via the official Github repo here:


Find all information about different official versions and releases here:


If you download Gekko from any other source you might get infected with malware. Today I discovered a youtube video with a download link to a malware loaded version of Gekko, you can find the details here (but be sure to NOT download from any of the links found there).

Be smart and safe everyone! Even if you download from the official repo it is still advised to not run any software on systems that also contain other private information (like crypto wallets) or not to connect it to your exchange account unless you fully understand what you are doing. Gekko is great at simulating trades with fake money, and it runs great in a VM as well.

  Increase performance?
Posted by: tommiehansen - 02-05-2018, 06:09 PM - Forum: Technical Discussion - Replies (6)

Any idea where to start to debug performance when backtesting?

e.g. i see that moment.js is used and also seems to be used on every candle which would seem to possibly be one of the culprints?

  NaN on PerformanceAnalyzer log
Posted by: Lucas - 02-05-2018, 04:19 PM - Forum: Technical Support - Replies (6)

Hi, after some weeks of paper trading, today I started to use gekko for real trading with trader plugin on bitstamp exchange.
I noticed a problem on log produced by performanceAnalyzer plugin:
P&L and profit columns reports NaN value.

(PROFIT REPORT) original simulated balance:      1000.00000000 USD
(PROFIT REPORT) current simulated balance:       1033.44000000 USD
(PROFIT REPORT) simulated profit:                33.44000000 USD (3.34400000%)
(ROUNDTRIP) entry date (UTC)    exit date (UTC)         exposed duration        P&L     profit
(ROUNDTRIP) 2018-02-05 00:28    2018-02-05 01:04        36 minutes              NaN     NaN

It's my problem or common problem?
How can I solve?

Thanks in advance.

PS: - with paperTrader I can see correct numerical values
- I'm running the stable branch (1cde4c4) on raspberry

  Problems with coinfalcon
Posted by: compilur - 02-05-2018, 04:00 PM - Forum: Other exchanges - Replies (5)

Hi folks,
I did some mess there. I opened a ticket for an issue on github for coinfalcon live-trading, but then after an update of gekko I recognized I even can't import data from coinfalcon. My bad, I also deleted my old log-files. So I can't reproduce this and can't you show any logs.

Here's the old issue

BUT: I can show you how to reproduce this bug (coinfalcon data-importing bug):
