Note, this example is real, it has happened when the blockchain forked. MtGox is a very reactive market, price dropped significally in 1 hour, this kind of situation opens very good arbitrage opportunities with slower exchanges.

• Tests
• Add other exchanges:
  • icbit
• Update order books with a WebSocket client for supported exchanges (MtGox, Bitcoin-Central)
• Better documentation
• Add fiat currency converters USD / EUR
• Replace float by Decimal
• Better history handling for observer "HistoryDumper" (Redis ?)
• Move EUR / USD from a market to an other:
  • Coupons
  • Ripple ?
  • Negative Operations
