Cryptocurrency mapping (e.g. BTC vs. XBT)

Not all exchanges use the same names for the same coins (e.g. BTC or XBT for Bitcoin). So that the system recognises it's the same instrument and trades it properly across exchanges, there is a mapping file algotrader/bootstrap/conf/src/main/resources/currency-code-mappings.csv. If the matching entry exists in that file (adapter code, exchange code and adapter currency code), then the defined AlgoTrader currency code will be used throughout the system and the adapter specific name will be used while communicating with the exchange.
