Messages

All messages sent to and received from IB will be a map which has an ::ib/op key which corresponds to the name of the EClient/EWrapper method names. It will also contain an unqualified keyword+value pair for each parameter, with the keyword corresponding to the name used in the Java Client source. See EWrapper for received messages and EClient for send messages. You can use ib/req->params and ib/recv->params to look up parameter names for a given method.

 :contract
 :endDateTime
