[whydifficult]

Hey, first of all, this project is a nice idear.

I installed it and want to trade at BTC-e


But I get the Error-Message:

Code:

Failed to load historical trades from bitcoincharts

the "Interval" is set to 30 mins at the moment, I also tryed 15 and 5 mins.


Has someone a solution?

Greetings


Edit: MtGox is working, but im looking for BTC-e

P.S. Also if I dont want to trade at Bitstamp, I get the Error

Code:

/home/gekko/methods/realtime-candle-fetcher.js:98
    throw 'Failed to load historical trades from ' + this.watcher.name;
                                                   ^

I am back guys.

I fixed the email & underscore errors: pull the latest version and `npm install` to get it working.

(Thanks avert for the email fix suggestion: implemented it the same way. For underscore: they removed a function I was relying on so I am now shifting towards lodash)

I'll check the code fixes posted asap and merge it in. Remember guys: Pull requests are always welcome!

'npm install' errors out on me.

EDIT: Fixed by installing git.

How do you install git on Windows? I'm getting the same error -- the instructions for Installing Gekko on Windows are clearly incomplete.

Try the latest version of Gekko, should be fixed now.

And there is a little bit of history behind this bug: after a broken update to the mail dependency I had to hotfix it, this change caused machines without git to fail (all my machines have git, so it took me a while to notice).

[whydifficult]

You can now also trade hashing power on the commodity exchange cexio!

Also a lot of small fixes (though still a couple of issues).

Stay tuned for more, I got a lot more planned.

Here is the ema diff calculation:

Code:

var diff = 100 * (shortEMA - longEMA) / ((shortEMA + longEMA) / 2);

I have the same problem with cex.io

how you can solve?

Also decreasing "candle" does not solve..

thanks in advance!

now it works 

[brampower]

This really is a great bot. I have no idea what I'm doing, but it works. Just wanted to say thanks a bunch for this, it is much appreciated!
Once I start making some nice BTC, a nice tip will come your way for sure.

[wariner]

I would like to configure Gekko to test the current EMA strategy on historical data of cex.io.

I can download somewhere the candle data in CSV format of cex.io?

Thank you

hi,

i would like to test it on cex, i got alwaysexchange credentials do not look valid.

i setup my key and secret and my username too. i added this to the advanced section too in config.js

any idee?

thx,

Lazac

[lazac]

works...missspelled a currency asset pairs...

[lazac]

an indicator, like Heiken Ashi, or ichimoku cloud would be nice...

[patriotek]

Hmmm...

Mine's been running in Simulated Mode for 3-4 days, with a CEX.io API key-set.

Currency is BTC, asset is GHS, and thresholds were each changed to -0.025 and 0.025 respectively, as I read that this is what most folks are using.

The result:  Each and every Profit Report (simulated) shows a NEGATIVE number.  The first was -9 and change, and it's progressively decreased to currently -15.xxx.

I've gotta' wonder, if I actually enabled trading with the defaults (and just the changes noted above), would I actually be losing money?  If so, how might I edit things to prevent this?

I can understand that there will be losses / chances of loss in the trading arena, but to lose at EVERY SINGLE TRANSACTION?  That'd be silly...

[Voodah]

Time to give this a try !

Thank you for creating Gekko. Getting ready to try it out very soon.

Keep up the good work!

which EMA setting is the best

interval = 60  (i think its to long)
short = 10?
long = 21?
candles: 100
sellTreshold: -0.25
buyTreshold: 0.25

thx a lot

Hi, I play with gekko since a bunch of days, any plans to add more currencies like LTC, NMC or adding others platforms such as cryptsy ? I found a module for its api in nodejs : https://github.com/nothingisdead/npm-cryptsy-api

You need to find that out for yourself! You can use the the backtester for that, more info in the docs.

I am currently in the phase of adding a bunch of exchanges, if anyone feels generous pull requests welcome! (Here is an explanation of how to add a new exchange to Gekko)

Lots of updates and bugfixes!

Note that cex.io is currently broken due there changed API.

Hi Mike,

We have limited our trade_history call to 1000 trades now, We will be implementing a daily trade static file in a future update I apologize for the inconvenence and we will try to get this out ASAP.

I hope we'll be able to implement a fix soon.
