"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken

While writing some interface code, I noticed that LOOKUP SLM / SST / STC / SSC / SNC doesn't seem to be able to take a [RequestID] as outlined in the docs...

... responds properly when RequestID is not included.

It ends up resulting in an !SYNTAX_ERROR!.

<see attached>

Obviously not a big deal - just happened to notice.

PROTOCOL: 6.2.0.5

Note that protocols are only Major.Minor. I'm guessing you meant IQFeed version 6.2.0.5 and the protocol you are using is unknown from your post.

With that said, I am unable to duplicate this behavior except on old protocols where RequestID was not yet supported on these commands (4.9-5.1). It would appear you are using one of those older protocols.

 S,SET PROTOCOL,6.2
S,CURRENT PROTOCOL,6.2
SLM
LS,1,NGM,Nasdaq Global Market,5,NASDAQ,
LS,2,NCM,National Capital Market,5,NASDAQ,
...
SLM,TEST
TEST,LS,1,NGM,Nasdaq Global Market,5,NASDAQ,
TEST,LS,2,NCM,National Capital Market,5,NASDAQ,
...


S,SET PROTOCOL,6.1
S,CURRENT PROTOCOL,6.1
SLM
1,NGM,Nasdaq Global Market,5,NASDAQ,
2,NCM,National Capital Market,5,NASDAQ,
...
TEST,1,NGM,Nasdaq Global Market,5,NASDAQ,
TEST,2,NCM,National Capital Market,5,NASDAQ,
...

protocol 6.0 is the same as 6.1 and 5.2 for this request)
S,SET PROTOCOL,5.2
S,CURRENT PROTOCOL,5.2
SLM
1,NGM,Nasdaq Global Market,5,NASDAQ,
2,NCM,National Capital Market,5,NASDAQ,
...
SLM,TEST
TEST,1,NGM,Nasdaq Global Market,5,NASDAQ,
TEST,2,NCM,National Capital Market,5,NASDAQ,
...


Here is where it stops working (and all older protocols). This is intended.
 S,SET PROTOCOL,5.1
S,CURRENT PROTOCOL,5.1
SLM
1,NGM,Nasdaq Global Market,
2,NCM,National Capital Market,
...
SLM,TEST
E,!SYNTAX_ERROR!,

Steve - thanks for setting me straight - definitely was not setting the protocol properly as you noted.

Thanks - John
