Gekko - a javascript trading bot and backtesting platform

[CaLPaR]

I don't know if this have suggested before, but I'm sure a lot of people would appreciate it you ware to add a support for the exchanges on cryptsy.com.
Cheers.

anyone actively using this atm with good experiences? gonna try it out soon. Looks great. Was looking into cryptotrader but this bot seems a good alternative and its free

anyone actively using this atm with good experiences? gonna try it out soon. Looks great. Was looking into cryptotrader but this bot seems a good alternative and its free

I'm using cryptrade which is free and works with the candles stored at cryptotrader (but with no backtesting) at cex.io using the exact same EMA settings gekko uses by default, and that's working out well. 0.55BTC being flipped between GHS and BTC has grown to 0.6 in under a week

BUT an instance of gekko doing simulated trading alongside it is (theoretically) making more, athough it's hard to count what with the mining that also occurs @ cex. Now that gekko-localdb can trade, I'll be switching over to it anyminutenow.

Here's about 3 days of gekko simulating trading:

Code:

2014-01-23 21:43:31 (INFO):	(PROFIT REPORT) original simulated balance:	 0.58611 BTC
2014-01-23 21:43:31 (INFO):	(PROFIT REPORT) current simulated balance:	 0.62616 BTC
2014-01-23 21:43:31 (INFO):	(PROFIT REPORT) simulated profit:		 0.04005 BTC (6.83275%)

cryptrade logs differently so the best I got from that is:

Code:

2014-01-23T22:16:17.819Z - verbose: updatePortfolio: { btc: 0.6083721, ghs: 0.00034388 }

and here's 2ish weeks in GHS. Obviously, pay attention only to the peaks. Methinks a little too twitchy.

I might have missed it through the pages, but is anyone else having issues installing modules from npm?

Ubuntu 12.04.3 here.

Why aren't you connecting to the default registry?

Also what version of node do you have?:

node -v

Your node version is too old. You'll have to use 0.10.x

First lets get Gekko working

[..]

To bad you are having trouble installing Gekko. The problems all have to do with the fact that the nodejs package shipped with the default ubuntu repos are heavily outdated (nodejs is being really actively updated and Gekko requires a newer version). To install the proper nodejs that won't cause any problems:

Code:

sudo apt-get update
sudo apt-get install -y python-software-properties python g++ make
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

(from the nodejs docs)

--

Note that Gekko is open source and I encourage everyone to give it a try. Though in the current state it's not focused on end users, it requires installing developer tools and a command line / configuration file style interface. I am working on a webbased (hosted) backtesting platform similar to CT as well as hosted real traders (far far future).

[glennmatthew]

First lets get Gekko working

What I failed to mention, is I had Gekko working fine on my Windows PC at home. I wanted to move it to a server for stability, my internet connection is pretty dodgy.

I'm actually more curious about your trading rules. I've been tweaking them to see if I can match different tolerance levels to risk. It's pretty experimental in itself, and I'm happy to lose the funds I'm trading with, in the name of art/science/finance.

I'll have a look re-migrating across to Ubuntu in a few hours, I appreciate your input

Awesome, I'm pretty sure we can run it on ubuntu as well. I'm currently running ~25 gekkos across different linux servers (centOS and ubuntu), also running Gekkos on OS X.

Most errors you posted came from NPM and I can't really make that more clear. But I just pushed an update to the localDB branch that will log an error when you try to run Gekko with an old, outdated node version:

Your local version of nodejs is to old for Gekko. You have v0.8.4 and you need atleast >=0.10.x

I'm actually more curious about your trading rules. I've been tweaking them to see if I can match different tolerance levels to risk. It's pretty experimental in itself, and I'm happy to lose the funds I'm trading with, in the name of art/science/finance.

I'm hoping to get to a point similar to CT where users can design / tweak their own methods. To do that we first need a bunch of indicators (and ta-lib, the library CT plugged in, will remain an optional choice for multiple reasons which means we need to write indicators ourselves).

If you have specific questions about the current DEMA, MACD or PPO implementation and what makes them trigger let me know!

[whydifficult]

anyone actively using this atm with good experiences? gonna try it out soon. Looks great. Was looking into cryptotrader but this bot seems a good alternative and its free

I'm using cryptrade which is free and works with the candles stored at cryptotrader (but with no backtesting) at cex.io using the exact same EMA settings gekko uses by default, and that's working out well. 0.55BTC being flipped between GHS and BTC has grown to 0.6 in under a week

BUT an instance of gekko doing simulated trading alongside it is (theoretically) making more, athough it's hard to count what with the mining that also occurs @ cex. Now that gekko-localdb can trade, I'll be switching over to it anyminutenow.

Here's about 3 days of gekko simulating trading:

Code:

2014-01-23 21:43:31 (INFO):	(PROFIT REPORT) original simulated balance:	 0.58611 BTC
2014-01-23 21:43:31 (INFO):	(PROFIT REPORT) current simulated balance:	 0.62616 BTC
2014-01-23 21:43:31 (INFO):	(PROFIT REPORT) simulated profit:		 0.04005 BTC (6.83275%)

cryptrade logs differently so the best I got from that is:

Code:

2014-01-23T22:16:17.819Z - verbose: updatePortfolio: { btc: 0.6083721, ghs: 0.00034388 }

and here's 2ish weeks in GHS. Obviously, pay attention only to the peaks. Methinks a little too twitchy.

So you are using the cryptrade for real trading right now? Let me know if the profit reporting is wrong (though note you have to set slippage level yourself, was added a couple of days ago). Though the implementation DEMA is not 100% the same at CT compared to Gekko's version.

So you are using the cryptrade for real trading right now? Let me know if the profit reporting is wrong (though note you have to set slippage level yourself, was added a couple of days ago). Though the implementation DEMA is not 100% the same at CT compared to Gekko's version.

Those stats were running CT, with gekko simulating trading with same settings on the side. They approximately agreed, and what you said about gekko's candles not being from 00sec to 60sec explained (some) variance.

Today I've started running just gekko, letting it trade and simulate at the same time. 1m period, Default DEMA & slippage.

so far simulation says:

Code:

2014-01-24 19:05:54 (INFO):	(PROFIT REPORT) simulated profit:		 -0.00385 BTC (-0.62741%)

Which is about right. Hard to measure exactly since I'm currently holding GHS, plus it's been a lame day on the cex curve for dEMA.
(edit: Now I'm back in BTC. Simulated: 0.61022 / Actual: 0.61072 )
(edit again: few hours later Simulated: 0.60987 / Actual: 0.61094 ) increase mostly mining. Trades happened, but variance tiny.

And tiny loss bothers me not a jot, since the bot is there to make sure massive lurches in the graph get acted on quickly. (basically, so I can sleep ever.) I can take a little hit to the balance on flat days that trick EMA slightly, 'cuz the days with movement in the graphs make up for it, and the mined BTC from holding GHS @ cex balances out little hiccup losses. EMA values to 'prefer' holding GHS in flatline and very slow drift situations would be better for cex though to maximise mining.

I'm specifically running sim and real trading at the same time because of the mining from GHS held at cex; sim will show me what I'd have made just trading, whereas actual will in theory be higher due to mining rewards. (edit: knew it.) It's entirely possible at cex that's it's more profitable to sell less often in order to keep mining.

Now I've seen it run and trade, more output suggestions!
'cos as it is now you can see simulation balances but not your actual balance...
So: after every trade, something like "Bought XX<asset> for XX<currency>" would help clarify.
And: a portfolio report with % gain/loss much like that of simulated trading would also be good after every trade.
Also: Successful has one L

One more thing: CT ignores amounts below 0.001, (i think) so there was always a bit of balance left in what one doesn't want to be holding. Word on CT's messageboard said that was a cex API limitation. Guess not, cos no such problem with gekko. Nice.
Another difference is that CT will sell mining rewards as they build up, often for unfavourable prices. Because gekko waits until the *beginning* of an EMA upswing, mining reward BTC are sold for GHS at the appropriate time, when they're (relatively) cheap. Double Nice.

Give it a day or two and I'll post how my graph looks after gekko's played with it!

Also: post your cex.io referral link already! Donations are nice but a referral is forever. Plus it's an utter delight having bot-wielding referrals in your cex charts, seeing them rise and fall as their bots trade the EMAs alongside one's own.

[glennmatthew]

Most errors you posted came from NPM and I can't really make that more clear.

I actually worked that out, which is why I was trying to use a proxy and connect to NPM directly.

It has been 5+ years since I've had to use command prompt on linux, so I wasn't doing too bad to get that far

[Thom]

Uh oh! Semi-critical error:

Code:

2014-01-26 11:15:30 (ERROR):	cancel order failed: Nonce must be incremented

I've noticed an identical error in cryptrade, so I'm guessing the actual error string is from cex itself, so maybe cex skips the odd nonce.
Difference is: when this happens, cryptrade carries right on regardless, but gekko hangs.
What it (probably) needs is to increment the nonce again and retry.

Also: this happened when there was an order open, which got left hanging.
When gekko started, it interpreted this as

Code:

GHS: -7.12206245

which obviously is weirdass, and makes things like this happen:

Code:

wanted to buy GHS but the amount is to small (-1.0696497) at cex.io

A "cancel / ignore open orders on start" line in the config and a tweak to the startup maths would help such confusion.

Edit: Once the order was cancelled by hand and gekko restarted, it traded it as usual.

Edit again: having restarted gekko a few times, it's clear that a "get trading sim start balance from real balance" option would help lots.

(edit: knew it.) It's entirely possible at cex that's it's more profitable to sell less often in order to keep mining.

Awesome let me know how it goes. You can always set the sell threshold higher so that only really steep downtrends would trigger a sell.

Now I've seen it run and trade, more output suggestions!
'cos as it is now you can see simulation balances but not your actual balance...
So: after every trade, something like "Bought XX<asset> for XX<currency>" would help clarify.
And: a portfolio report with % gain/loss much like that of simulated trading would also be good after every trade.

Thanks will look at this.

EDIT: someone requested that we output the trades into a CSV file. Is this also something you would use?

One more thing: CT ignores amounts below 0.001, (i think) so there was always a bit of balance left in what one doesn't want to be holding. Word on CT's messageboard said that was a cex API limitation. Guess not, cos no such problem with gekko. Nice.

I'm interested in all your feedback! Here is my [reflink](https://cex.io/r/0/askmike/0/) btw.

Uh oh! Semi-critical error:

Code:

2014-01-26 11:15:30 (ERROR):	cancel order failed: Nonce must be incremented

A "cancel / ignore open orders on start" line in the config and a tweak to the startup maths would help such confusion.

Edit: Once the order was cancelled by hand and gekko restarted, it traded it as usual.

So this error has probably to do with you using the same API keys for both CT and Gekko. The nonce has to do with security around the API: in every request applications do to the API they have to send a counter and this counter always needs to be higher than the last one. This is easy if you do all the requests (just write down the last counter everytime and up it by one). Though if you have the same keys for both Gekko and CT they will clash because they are unaware of eachothers counter.

Gekko and CT use the same library to connect to CEX.io, Pulsecat was the author (though he copied it from my Bitstamp code). A fix for this particular issue has been suggested almost 2 weeks ago. Unfortunately pulsecat needs to accept this fix and has not done this yet.

Edit again: having restarted gekko a few times, it's clear that a "get trading sim start balance from real balance" option would help lots.

Great idea Thanks!

Could you list the contents of the gekko-master folder on your desktop? (screenshot for example).

It's a convoluted quote-a-thon!

Awesome let me know how it goes. You can always set the sell threshold higher so that only really steep downtrends would trigger a sell.

Yeah, I tweaked the buy/sell thresholds which, coupled with yesterday's moves @ cex = profit

One uninterrupted 24hr session overnight yielded:

Code:

2014-01-27 12:11:16 (INFO):	(PROFIT REPORT) original simulated balance:	 0.65978 BTC
2014-01-27 12:11:16 (INFO):	(PROFIT REPORT) current simulated balance:	 0.69191 BTC
						ACTUAL balance:			 0.67235958

Simulation mode is currently way optimistic, which is weird: since it doesn't account for mining, it really should be under, not over.

EDIT: someone requested that we output the trades into a CSV file. Is this also something you would use?

YESSSSSSSS. I currently lift CSV data from cex to visualise bot winnings, but raw csv from gekko would be good (IF it kept a constant eye on your balances and had them in the CSV)

Uh oh! Semi-critical error:

Code:

2014-01-26 11:15:30 (ERROR):	cancel order failed: Nonce must be incremented

So this error has probably to do with you using the same API keys for both CT and Gekko.

Actually nope, gekko was my only thing running on that api key that day. Plus I've run CT and gekko and my crappy little namecoin selling bot all together before on the one API key and it hasn't given a hoot. Regardless, an increment and retry should fix the hang.

A new observation: when gekko said this, it actually meant "sell", not buy. suggest change to "trade"

Code:

2014-01-27 13:42:26 (INFO):	wanted to buy GHS but the amount is to small (0) at cex.io

Edit: and here's today's weirdness:

Code:

2014-01-27 14:32:25 (INFO):	wanted to buy but insufficient BTC (17.39210254031083) at cex.io

What. Also that isn't the BTC balance in brackets, it's the GHS equivalent. What? Only happened once on startup. After restarting, it was fine.

I'm interested in all your feedback! Here is my [reflink](https://cex.io/r/0/askmike/0/) btw.

You got it: Feedback: Awesome! Gekko + cex.io = profit.

Lags / bugs out / hangs *far* less often than cryptrade with the localdb, and comes up with a little more than CT in terms of profit.
Gekko candles not having to start at 00sec makes for much agility too. Is it possible to run at sub-minute intervals? I'm scared to try.

After a while (specifically after I've watched charts and made myself understand MACD & PPO) I'll run a second gekko instance with different config... And when I do, your referral link is getting some action. Slap it in your sig too, me talking cex so much in the gekko thread and lauding it for being a reasonably "safe" exchange to test a tradebot in can't hurt your odds of signups.

I'm not sure, but does Gekko simulation take transaction fees into account? That might be the reason for your discrepancy. I also find it surprising you trade succesfully at cex. I thought that market only had one direction... down...
