Hi,

I am new to this bitcoin trading.

I followed https://github.com/askmike/gekko#install and installed the setup in windows 7.

I tried the command node gekko

Below is the result I got on executing it.

Failed to load historical trades from bitcoincharts

Kindly can you please help me in solving this problem.

Currently I have $100 in my account. Will that be sufficient to start automated live trading with this bot in BTCe?

Only if your willing to lose $100. This isn't an "out of the box" bot the setting are up to you to work out, I backtested the default setting and got mixed results, over some periods this bot will result in critical failure without a stoploss method implemented so be careful if your putting in everything you've got.

And as far as your problem did you "git pull && npm install" bcuz the bot won't work w/o updated dependencies.

Edit:This error is so unavoidable and common if your install is right you might want to edit the +moment.duration, I set it to one so I can just blitz bitcoincharts till they send me something.

Its really strange but I can get this to work on Ubuntu 12.04 but no Windows 7.

Windows 7 returns bitcoincharts returned an error retrying.

When I was first trying on windows and got this error I thought it was a problem with either bitcoin charts or the program, but the fact that the exact same install returns this error on windows and not ubuntu is mind blowing. I've tried with the firewall down and everything.

Maybe there's some problem with windows blocking permissions to dependencies? Or maybe just inbound requests from the program?

Hi Whydifficult,

Have you given up on this project? Bitstamp has implemented yet another API change.

but on bitstamp I still get

Failed to load historical trades from Bitstamp

yeah as i said, Bitstamp and Bitcoincharts had their api changed. not only the api links changed, also the trades are returned from oldest to newest now. this is why the fillbuckets function doesnt get the expected data and cancels. try to fix it fr bitstamp as well as i did for bitcoincharts or just wait for the author to fix it. i think hes on it and it wont take much time for him.

The command you should use is 'node gekko'

not 'node gecko'

Hope that helps.

thx, sorry was a typo

EDIT: Fixed by installing git.

Since the latest version you need git to pull in one of the dependencies, I'll ask the dependency maintainer to update it so this won't be an issue anymore.

Edit: here is the issue I created

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.

Well,

I think I got it.

First of all you have to change the source where email.js is retrieved:
/gekko-master/package.json

Code:

"emailjs": "0.3.x",

After this it will successfully install via npm.

Step 1 Change Bitcoincharts Api Link:
/gekko-master/node-modules/bitcoincharts/bitcoincharts.js

Code:

/**
* The client for bitcoincharts.com API.
*
* @constructor
*/
var BitcoinCharts = function() {
this.url = "http://api.bitcoincharts.com/v1/";
};

Step 2 Change reversal of trades.csv:
/gekko-master/exchanges/bitcoincharts.js

Code:

Watcher.prototype.getTrades = function(since, callback, descending) {
  var params = { symbol: this.symbol };
  if(since)
   // we don't want to hammer bitcoincharts,
   // this will fetch trades between start and now
   params.start = since.format('X');

  var args = _.toArray(arguments);
  this.bitcoinCharts.trades(params, _.bind(function(err, data) {
   if(err)
   return this.retry(this.getTrades, args);

   if(!data || !data.length)
   return this.retry(this.getTrades, args);

   // normalize the data
   var trades = [];
   _.each(data, function(array) {
   trades.push({
   date: array[0],
   price: array[1],
   amount: array[2]
   });
   });

   if(descending)
   callback(trades.reverse());
   else
   callback(trades);

  }, this));
}

Step 3 Change how the latest trades are fetched:
/gekko-master/methods/realtime-candle-fetcher.js

Code:

// this method fetches most recent trades and calculates a new candle based on the trades
CandleCalculator.prototype.getNewCandle = function() {

  if(this.fetchingHistorical)
   // we just fetched all historical buckets
   this.fetchingHistorical = false;
  else
   this.removeOldestBucket();

  this.removeOldestCandle();

  log.debug('fetching new trades for new bucket at', this.watcher.name);
  this.watcher.getTrades(util.intervalsAgo(1), this.fillNewBucket, true);
}

Its a quite simple workaround and of course not that beautiful but fetching trades from Bitcoincharts should be fixed then.
But it would be nice if the author or any other trusted programmer could test and validate those changes.

Have a nice weekend gekkos.

Hi gekko fans!

This program could be awesome. But recently i only get

Code:

Failed to load historical trades from bitcoincharts

.

I already tried to change the api link to the new one http://api.bitcoincharts.com/v1/ but it keeps failing. I spend some hours on debugging via node-inspector and i think it has something to do with the realtime candle fetcher and the following lines:

Code:

// fill buckets based on the trade data.
CandleCalculator.prototype.fillBuckets = function(trades) {
var latestTradeDate;
var startBucket = this.currentBucket;

var emptyBucket = true;
var nextBucketTime = util.intervalsAgo(this.currentBucket);
_.every(trades, function(trade) {
var time = moment.unix(trade.date);
// as long as this trade is to recent
// it should go to the next bucket
while(time > nextBucketTime) {
if(emptyBucket === true)
return false;

Actually im neither good in developing nor familiar with javascript.

But i would really appreciate a fix on that.

Please excuse my rather bad english.

in javascript you don't have to write:
if (typeof _.first(bucket) == 'undefined')

you just could write:
if (_.first(bucket))

but this will catch also null values and other falsy values, it can be good thing, it depends.
If want only check for undefinied you can write:
if (_.first(bucket) === undefined)

Added the if statements to the code, and now it seems to be working again. Thanks!

I'll have to wait until the next sell signal to start trading again, though.

Something odd happened today: I had Gekko running in the background for like a day or so (trading in MtGox), but suddenly I got a signal to sell, even though the chart on bitcoincharts didn't give any indication to do so. When I closed and reopened it, I got things like this:

Code:

2013-09-11 00:18:56 (INFO): ADVICE is to HOLD @ 129.043 (NaN)

Ran it again with config.debug set:

....

I had the same thing with NaN appearing after the data from MtGox was interrupted, after adding the if statements it appears I'm only missing two candles (20 & 21) when running with debug set to true. Better than waiting until the candles are out of the array as previously stated.

It's now back to calculating the EMA from the available data coming in.
