+## Current Features for {{.CapitalName}}
++ The state manager keeps currency states up to date, which include:
+* Withdrawal - Determines if the currency is allowed to be withdrawn from the exchange.
+* Deposit - Determines if the currency is allowed to be deposited to an exchange.
+* Trading - Determines if the currency is allowed to be traded on the exchange.
+
++ This allows for an internal state check to compliment internal and external 
+strategies.
