Hello,

I extract the version string from the S,CUST message to determine functionality and availability of services.

I have 6.2.0.23 installed. Yet I see 6.1.0.20 in the statement.

S,CURRENT PROTOCOL,6.2, does work to enable certain operations but it would be useful to see that the right version is in place to start with.

There are Level 2 functions which have only recently been released and I would like to check the version prior to enabling/using those functions.

Are you certain that when you initially connect to IQFeed you specify S,SET PROTOCOL,6.2 in *ALL* the connection ports?

The SET PROTOCOL is a bit of a red herring.

Upon connection, I get:

$ telnet 127.0.0.1 5009

Which all arrives prior to being able to do the SET PROTOCOL

This field in the S,CUST message indicates the latest official version of IQFeed, which is currently 6.1.0.20. Remember that 6.2 is still in beta mode and not the officially supported version [yet]. Simply run the S,SET PROTOCOL,6.2 after you receive this message and you should be ok. You will see that the 6.2 protocol is used by an incoming S,CURRENT PROTOCOL,6.2 message. Note that you need to repeat this protocol setting for all ports, not just the Admin port.

Ok, to wrap this up: I'm hoping that DTN will make a note and maybe look into a mechanism where the developer can determine the actual version being connected such that the application can then make appropriate services available for the functionality actually supplied.

Hello, the official release version is 6.2.0.23 currently (not 6.1). The version field in the S,CUST message also controls the IQFeed version Upgrade Nag so it has always lagged the actual release date by a bit of time to allow a small number of customers to upgrade naturally before we turn on the nag. Unfortunately, with the timing of data center move, we didn't want to have both happening at once so we are delaying the upgrade nag until after the datacenter move is complete.

However, the current version field in this message does not indicate (and never has indicated) the installed version. For example, once we update this field after the move, customers running 6.1 or older versions will still get a 6.2 version number in this field.

The installed version would either have to be pulled out of the registry (documented here: https://www.iqfeed.net/dev/api/docs//RegistrySettings.cfm) or by examining the file information of IQConnect.exe.
