I was working on the software trading bot which would do arbitrages between exchanges and triple arbitrages on the same exchange.
For now the project is 90% ready, it can work with 23 exchanges in public API mode (check current prices and orders etc) and with 5 exchanges in private API mode (place orders).
These 5 exchanges are: Cryptsy, Coins-E, Comkort, Poloniex, SwissEx.
The program can search for best arbitrage opportunities both in cross-exchange (buy on one exchange, sell on the other) and one-exchange (triple and more arbitrages) modes, but can't place actual orders yet (the part of placing needed orders still has to be coded).
Now Russian government is engaging a law against any cryptocurrencies, and I don't want to have any problems with the law.
So I decided to sell the source code.
It is written on Java 7, all libraries and stuff will be included.
If you're interested please PM me.
