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".

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?

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)

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 ?

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.

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

Quote

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

...

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.

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.

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).

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

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

Yes, but the verbose mode, is too verbose Wink

oops, just realised.

"MtGox API url changed"

Redownloaded package from github and boom, back in business!

I wonder why they changed it?
