My application connects to a C# API. I have a problem with an Event Definition. This is the definition:
Event tickByTickAllLast(reqId As Long, tickType As Long, time As String, Price As Double, Size, tickAttribLast As ComTickAttribLast, Exchange As String, specialConditions As String)
My question: is the 'Size' variable defined as 'Double' or as 'ComTickAttribLast' i.e. does it take the data type from the preceding or following data type?
I have no knowledge of C# (that may be obvious).
Thank you.
