Give us some clues please!
?
Like what API implementation are you using?
Hi all is there ANY reason that calling reqMktdata using "SPX" , "CBOE","USD" as parameters would cause
sending | ┌ Error: exception thrown
│?? e = TypeError: in typeassert, expected Float64, got a value of type Nothing
and no data?
I can send the same reqMktdata for any symbol and it works perfectly.
