been getting this non stop all day

Code:

2013-03-19 21:19:57,178 [ERROR] HTTPError, can't update market: MtGoxUSD

[DobZombie]

oops, just realised.

"MtGox API url changed"

Redownloaded package from github and boom, back in business!

I wonder why they changed it?

[maxme]

I'm running this in test-mode atm. Is it supposed to do this?

Yes, but the verbose mode, is too verbose

[maxme]

If you'd like to add ICBIT support, I will be glad to help.

Do you have an HTTP API to get the market depth (order book) ?

[Cyrus]

I actually found it on github first and now came here searching for the announcement thread.

Is the current version working?
I want to start testing today

And also... would like to see btc-e support soon! Great job .

Aw man, you mean I spent my time building my own arbi-bot (probably a whole lot crappier than yours) for nothing?
Care to explain why you are giving this away for free?  By facilitating the effort required to start arbitraging, you are diminishing your own profits... (and mine   )

Good arbitrage helps bitcoin economy and helps decentralize markets (e.g. helps other exchanges grow).

[whizter]

What exactly do I have to do to make it trade? It just does this all the time but no trades are happening, the same stuff as in my first post above. I'm using the newest version from github.

Of course I set my gox api keys and the bitcoincentral credentials. This is my conf:

markets = ["MtGoxEUR", "BitcoinCentralEUR"]
observers = ["Logger", "TraderBot", "HistoryDumper"]
market_expiration_time = 120 # in seconds: 2 minutes

...

[maxme]

observers = ["Logger", "TraderBot", "HistoryDumper"]

...

I think you're crazy to do that... Did you read the code first ? Are you sure that it will not just steal your coins ?

First, in TraderBot.py, you'll see some safeguards, for instance if the expected profit is lower than X and the expected profit percentage is lower than Y then it will not execute transactions. One of these safeguards should block current transaction.

But seriously, it's not a "packaged product", it's more a in-development project released for other developers. If you just run it like this, I guarantee you'll lose money.

If you really want to run it on real exchanges, then help me to write automated tests.

[Khertan]

Now i understand why you didn't put the perc_threshold and profit_threshold in the config file :p

[maxme]

Now i understand why you didn't put the perc_threshold and profit_threshold in the config file :p

Haha

I would like people to write their own "TraderBot" class and not use the default. I should rename it to SampleTraderBot.

[Khertan]

Indeed but we can also write a good default one ... i'm a beginner in arbitrage domain ...

[Khertan]

There is something strange :

2013-03-20 16:31:32,985 [INFO] profit: 0.007277 EUR with volume: 0.010000 BTC - buy at 48.0000 (MtGoxEUR) sell at 48.0000 (BitcoinCentralEUR) ~1.52%

1.52 % with bought at 48 and sell at 48 ... due to rounding ?

[maxme]

Nope, it's not a rounding problem and it's not an issue.

The "buy price" given by the program is the maximum price you should buy BTC at.
The "sell price" given by the program is the minimum price you should sell BTC at.

Example with this order book:

Code:

books = {
    'MtGoxEUR':
    {'asks': [{'amount': 1, 'price': 47.0},
              {'amount': 2, 'price': 47.3},
              {'amount': 1, 'price': 48.0},
              {'amount': 3, 'price': 49.0}]},
    'BitcoinCentralEUR':
    {'bids': [{'amount': 1, 'price': 48.2},
              {'amount': 2, 'price': 48.1},
              {'amount': 1, 'price': 48.0},
              {'amount': 5, 'price': 47.9}]}}

Output will be :

Code:

volume: 3.0 BTC buy at 48.0 (MtGoxEUR) sell at 48.0 (BitcoinCentralEUR) 

Note: volume is 3.0 btc, not 4.0 btc (that includes 48.0 price)

[DobZombie]

I don't intend this to be a dumb question but I fear it will be...

Does this bot require 2 exchanges for trading to happen? If yes is it possible to do trades with only 1?

[maxme]

Does this bot require 2 exchanges for trading to happen? If yes is it possible to do trades with only 1?

Yes it requires 2 exchanges. Arbitrage means "buy at X on a market and sell at X+y on another market at the same time".

http://en.wikipedia.org/wiki/Arbitrage

[Sukrim]

Well, I could trade on MtGox in BTCUSD and BTCEUR if I know EURUSD (or assume EURUSD as static - compared to BTC that might even be true)...

If there's a plugin for other "real" Forex brokers that might even work quite well! Still it might be enough to do fiat trades in bulk after some time, as the volatility is quite different there. Hence it might be possible to trade two currency pairs on the same "market".

[DobZombie]

I told you it was a stupid question

Also, I'm getting this A LOT

what am I doin wrong? Is it possible for this error to come up if the network is congested? Also, It takes about an hour or more for this to come up

You're doing nothing, wrong. That was my bad, update the code. And yes it come from no-responding websites

[Khertan]

Thx for explanations, i understand it after reading a bit more the code.

Also i was thinking of withdraw btc between exchanges place.
Example : buy one btc from bitcoin-central, sell at mtgox, withdraw one btc from bitcoincentral to mtgox 1 btc.

Did you think that a bad idea ?

It ll be more interesting if we can also transfer fund in euros between market, but that s not possible from api.

[w1R903]

Does this bot require 2 exchanges for trading to happen? If yes is it possible to do trades with only 1?

Yes it requires 2 exchanges. Arbitrage means "buy at X on a market and sell at X+y on another market at the same time".

http://en.wikipedia.org/wiki/Arbitrage

No, it certainly doesn't require 2 exchanges.  There are thousands of people doing cross-currency arbitrage as we write this.  See: http://en.wikipedia.org/wiki/Triangular_arbitrage  This can be done in a single exchange.

And cross-currency arbitrage is getting quite popular in exchanges with several virtual and fiat currencies, like vircurex and btc-e.

A market is not synonymous with "an exchange".  Each exchange has multiple markets (usually): USD-BTC, EUR-BTC, LTC-BTC, etc.

And of course, spot/futures arbitrage

[DobZombie]

okay, So I was getting this

Code:

Traceback (most recent call last):
  File "arbitrage.py", line 186, in <module>
    main()
  File "arbitrage.py", line 183, in main
    arbitrer.loop()

    self.tick()

    perc2, weighted_buyprice, weighted_sellprice)
  File "E:\BotEUR\src\observers\traderbot.py", line 63, in opportunity
    if volume < config.min_tx_volume:
AttributeError: 'module' object has no attribute 'min_tx_volume'

So I added this to the config.py

Code:

min_tx_volume = 0  # in BTC

But now it does this

Just to be sure, you use the TraderBotSim or you are ready to lose money and btc ?

[DobZombie]

I tried the traderbotsim in an older build and it didn't work.  But I works for me in the recent revision.

I've tried using the traderbot and all I get it this

It seems you made your first automated transaction.

The line above is a safeguard, it waits for TraderBot.trade_wait before executing the next trade (this will be removed when websocket order book sync is implemented)

[DobZombie]

I'm using the SpecializedTradingBot and it's outputting this...

[arsenische]

DobZombie, great work!

But why did you share the code? I think more competitors => less arbitraging possibilities. Or am I wrong?

[Sukrim]

More arbitrage --> more volume for trading bots!
Also the "algorithm" behind arbitrage bots is not really a secret at all, it might be better to get people to code up plugins for various APIs than to keep it a guarded secret. Also moving big amounts of money between exchanges is not trivial and not cheap too...

Thanks for actually open sourcing and releasing a useful and potentially profitable bot.

[DobZombie]

DobZombie, great work!

lol, I'm not sharing any code!  I'm just testing it 

maxme is the genius behind this code

[NF414]

Thanks for sharing!

Anyone had any real-life profit from this automation yet?

Regards, NF414

[maxme]

Yes I made some profits. But I had to stop the bot since some markets are sometimes not responding or replying with erroneous data. So I'm currently working at checking exchanges status/responsiveness and verifying trades.

And I need to write more automated tests for this part (like mocking erroneous response, ...)

I'm stuck finding the error (help)

o.0

[somecdnguy4]

Hmm, the bot immediately closes if I include either SpecializedTraderBot or TraderBot, but not if TraderBotSim is included. Also, when trying to include BTC-e, the bot says

Code:

"[WARNING] Can't automate this trade, client not available: BTC-e

Though, upon viewing the TraderBotSim file code, I notice it doesn't fully include BTC-e support. I'll keep looking into it.

Someone earlier asked about inter-market trading. Any plans to support that in later releases?

[maxme]

The private part of BTC-e API is not implemented _yet_

[maxme]

I pushed a new feature: fiat currency mixed trades. Now you can buy on market X with EUR and sell on market Y with USD.

Note: Fiat rates conversion are updated every hour from http://rate-exchange.appspot.com/

Is there no way to transfer funds between exchanges? Otherwise why would it be beneficial to buy low on one and sell high on the other?

[maxme]

You may:

• withdraw funds from an exchange and deposit to an other exchange (manual and long operation, painful, cuts profits with fees)
• wait for a counter operation and buy low on the exchange you sold previously
• use other currencies (ltc for instance)
• wait for an equilibrium and do a negative operation only to transfer funds from one exchange to another (cuts profits of course)

[JstnPwll]

Hmm. It seems like the most automatic method would be to code it so that when there's an equilibrium, both accounts trade out some of the currency they have been selling for the currency they've been buying. Like you said, it would cut profits (especially with trade fees), but that might be better than stagnating and missing good trade opportunities.

P.S. Thanks for the code! I'm having fun looking at it.

Thank you very much

Wil do it tonight

yep all working

just in tradersim mode

thanks

Well, I could trade on MtGox in BTCUSD and BTCEUR if I know EURUSD (or assume EURUSD as static - compared to BTC that might even be true)...

If there's a plugin for other "real" Forex brokers that might even work quite well! Still it might be enough to do fiat trades in bulk after some time, as the volatility is quite different there. Hence it might be possible to trade two currency pairs on the same "market".

U will never make money arbing a forex broker. If u trade against broker u will be banned and id u trade against the bank u will get last looked to death.

Greetings!

Just found this tool out.

It's great!

Just some suggestions for TODO:

* Add Triangular Arbitrage calculator and automated arbitrage implementation of it: as previously said - "This can be done in a single exchange";

* Add automated arbitrage for altcoins pairs (LTC/BTC; NMC/BTC; PPC/BTC; XPM/BTC etc.);

* Add support for exchanges with medium volume and various cryptocoins (such as Vircurex and Cryptsy);

Ps.: forget Ripple support...  

BTW, here goes some codes and other similar ideas in order to get some insights:
