I think my instance of gekko isn't working with BTCe. I have an account configured, and Gekko uses a 4h 10/21 EMA for trading, it shows this every 4h:
2013-07-19 12:33:26 (INFO): ADVICE is to HOLD @ 83.839 (NaN)
Notice the NaN there. The price changes of course. The reason I think it's not working is that it didn't sell since 2013-07-17, ignoring the price drop yesterday.

Bitstamp has changed their API. The current implementation will stop working by the end of October. I've also created a copy of this issue for your Bitstamp node module.

If I set interval in config.EMA to less than 60, it often crashes.

It's been doing this for over 20 minutes. Is this OK?
I am using BTC-E.

I've tried to use gakko to trade litecoins on at btc-e. I've set the exchange to 'BTCe', asset to 'LTC' in the config.normal and in config.watch sections, and when I start gekko it shows me "ADVICE is to HOLD @ 101.300 (NaN)", which is the price of of btc/usd on BTCe.

I am getting the following info log

2013-05-29 02:00:10 (INFO): ADVICE is to HOLD @ 128.990 (-0.140)

My config.js has the following values:

config.watch = {
exchange: 'MtGox',
currency: 'EUR',
asset: 'BTC'
}
...
config.traders = [
{
exchange: 'MtGox',
...
currency: 'EUR', // You probably want this the same as in the watcher
asset: 'BTC',
enabled: true
},

The advice value looks more like the current USD value rather than the EUR value I set in the config.

Trying to get Gekko to auto trade but it seems to be a problem when it tries to get the GHS balance from cex.io and thous it can't sell GHS.

BTC saldo and buying works though...

Are there any plans to add Cryptsy exchange in the future ? :)

It will be good to have, I may test it with xpm/btc for example

When asking for data from over 150,000 seconds ago Gekko will receive candles where the oldest one is a lot newer than the since date. This will cause the first couple of candles to be NaN and all EMA calculations will glitch from that point.

Hi!
I assume the market for bitcoins will rise in longterm.
So I assume that keeping bitcoins bought at higher price is better than sell it for less than bought (+ fee).
Is this beeing calculated?
Or is it just buy all/sell all ?

Hi,

just a short question about the following:

// start balance, on what the current balance is compared with
simulationBalance: {
// these are in the unit types configured in the watcher.
asset: 1,
currency: 100,
},

Could you please briefly explain what exactly those values mean.

Its better to use btc-e data from api instead of bitcoincharts. It allows resolution up to 10 seconds

Hi!

I've tried to run Gekko, and it shown message about calculation and then advice, but then it stuck and showd nothing during the all night. Is it the issue or there are no messages when you shouldn't do anything?

Also, how often Gekko asks MTGoc about new information?

When looking at the charts I think it looks like (for mtgox), that the EUR charts are a little bit behind the USD charts and I was wondering if it could be possible to trade EUR-BTC based on the data from USD-BTC.

Just to let you know that when getting trades from BS Gekko always quits with the message above.

I tried to understand whats going on, but I was unable to figure it out from the code.

I left gekko running for a few days, and it continued to report an uptrend despite the fact that the market was in an obvious downtrend. I restarted gekko, and only then did it start to accurately report that there was a downtrend. Specifically, when I restarted it it was reporting +1.091, and afterwards it reported -0.274. Unfortunately I don't have any debug information to go along with this.

Is it possible to add a variable to config.traders sections per exchanger that sets the trading fee so that it could be taken into account as well?

Hello,
My problem is that I set simulation balance to asset=1 and currency=0 with trading BTC/USD on BTC-e but the fisrt advice is to BUY asset.
I have tried to set another values in the config file but the first advice is always to buy asset.
Can you help me to find the problem ?
(Sorry for my english I am french with "scolar english")

When setting Gekko to pull data from BTCe nothing is actually being pulled from anywhere and Gekko seems to be stuck on Calculating EMA on historical data...

When enabling debug mode:

2013-11-28 12:50:29 (DEBUG):    fetching historical data at bitcoincharts
2013-11-28 12:50:29 (DEBUG):    bitcoincharts returned an error, retrying..

(And just as a side note: Would BTC/LTC trading on BTC-e be a possibility with Gekko?)

Seeing a white wall of text can be...hard to read. So here's a nice change.

You'll need to install 'colors' first in NodeJS (npm install colors)

in the 'exponential-moving-averages.js'

Add this to under '// helpers':
'var colors = require('colors');'

Now go to here 'Buy', 'Sell', 'Hold' are located (do a word search).

and change them to:
'this.emit('advice', 'BUY'.green, price, message);'
'this.emit('advice', 'HOLD'.yellow, price, message);'
'this.emit('advice', 'SELL'.red, price, message);'

FOR EVER INSTANCE OF BUY, SELL, HOLD

PS: Not sure where 'improvements' go, Askmike, so I posted here :)

I seem to be getting an error (https://gist.github.com/olanmatt/5996704) at random intervals. Not sure if it just me, but it seems like something that is undefined it being called.

Thanks

Hi,

Any idea what could be wrong?

Mike, correct me if I'm wrong, wouldn't it be quite simple to implement a stop-loss trading method in gekko? This would be useful in bubble territory :-) what do you think?

was working fine earlier and just recently did this

Right now when you fetch cexio for the first time it will build a database of trades, the starting point is currently hardcoded which means that as time goes on the database will get bigger on first fetch for no good reason.

I wanted to backtest agaist more recent data, but the provided candles go only up to 2013-05-23. So I tried to dump them myself, following your instructions here:
https://bitcointalk.org/index.php?topic=239815.0
After many hours of work it turns out that the dump tool also downloads only up to 2013-05-23. Do you know the reason for this? Is there a way to go up to today?

The bot seems to freeze immediately after giving the advice.

2013-06-21 12:29:06 (DEBUG): we are currently not in an up or down trend @ 81.605 (0.007)

Waited multiple hours, tested with different configs.

Currently I have an issue setting up the config to cex.io for ghs/btc trading. I've put in my api with all accesses to ensure it wasn't a api issue. Ive activated the api also.

The bot works fine when I disable real trading but when I enable it for real trading, I keep getting this error.

What do these errors mean? Is it related to how I set up the real trading information? Or is this a api error related to gekko?

My OS is Windows 7.

A lot can happen in an hour. Just look at the drop on mtgox a few hours ago. I don't know much about EMAs, but wouldn't it help to do the calculations more often? I'm not talking about decreasing the timeframe of the candle, just redoing the calculations for the last 100 ticks every few minutes with every tick lasting 1h.

One other thing to consider - what is the safe interval to not get banned by mtgox for to many requests.

Or this could be pure nonsense ;)

When I try to run gekko for BTC-e, I got this confusing error:

Failed to load historical trades from bitcoincharts

After a lookup of the source code and compare to bitcoincharts' API (http://api.bitcoincharts.com/v1/trades.csv?symbol=btceUSD ), I discovered that bitcoincharts returns trade data ascending. But in gekko/exchanges/bitcoincharts.js, it is treated as descending:

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

Switch the callback parameter and my problem solved.

Is there some trick config setting to so that the program will print during trade simulations?

It will be good feature eg for LTC/USD or other pairs

TODO...

Thanks a ton for everything so far.

Curious if there are any plans to integrate support for the btc-china exchange?

I have some utilities in my fork for fetching data / backtesting btc-china (forgive me it's greasy).

Thanks
