I've had the impression that arbitrage is only possible among a triangle (or square....) of pairs shaping a cycle, for example BTC/LTC, LTC/XPM, XPM/BTC, or for a pair existing in two different markets (like BTC/$ in MtGox and BitStamp).
But I see that in cryptsy almost all alts are traded against BTC which makes me confused about how your trader is supposed to make any arbitrage trade there. Could you explain this?

Have you used your own trader? How about some results?

Yep ofc I use it. Last 3 days a total win of ~0.5 BTC (Low trading volumes for me as i do not have that much funds)

I wrote an arbitrage trader in Python and want to share it with the community:

https://mega.co.nz/#!X0ZkwRJa!bxdS2Ch2NvXdPDACTsUbYkrlZbN_R9v51OZWkyEj8ms

It does compare the prices sell / buy for various Altcoins on the exchanges: Coins-E, BTC-e, Vircurex and Cryptsy.
It executes the Sell / buy trades as arbitrage of given percentage is found.

Usage:
Edit the config.py with your Keypairs for every exchange
Edit the value "amount" if you like to
Have at least the amount of altcoins you set in the config in your available funds of each exchange. BTC fund has to be highest price altcoin * amount

Run arbitrage_trader.py

It is not totally completed yet, what i will further implement:
- Error handling on connection errors
- Percentage of available funds to be traded instead of fixed value
- Maybe easier edit possibility for more / less coins

If you like this please donate to help my development!

If you encounter any bugs or wish to have more exchanges, or have any other feature request, tell me

Please remember, there is absolutely no guarantee there is any arbitrage at all! I am not responsible for any loss, especially when you modify the code yourself!
