MtGox supports many different currency formats. I'd like to know if each currency/BTC trade is independent of any other and the valuation isn't always perfectly aligned.
If someone wants Yen for BTC, but many other people want Dollars for BTC there is a supply / demand problem. One way to fix this is to automatically convert dollars for yen and absorb a currency conversion fee.
Does MT Gox internally automatically equalize these market forces?
Does a Bot perform these actions (at a rate of .60% per trade)
What are the computations used to ensure the bot is profitable?
