Trading system bitarb/bitarb.go conducts high-performance concurrent arbitrage across Bitfinex, OKCoin USD, OKCoin CNY, and BTC China. Position management is fully automated. The system is functional and can be run autonomously but is not intended as a turn-key system for general use.
Configuration settings are in bitarb/bitarb.gcfg. Environment variables exchange_KEY and exchange_SECRET are needed for access to each exchange. New exchanges can be added by implementing exchange.Interface.
