Detailed Description

A strategy parameter update the engine applied (ParamUpdateMsg): after the header, the message's bytes past its own header, so the fields sit at the same offsets.

hdr.instrument is the update's target, invalid for every instrument. The store names the fields through the session's parameter table (SessionOpen::param_table).
