I tried to follow your instructions on how to get the Nasdaq code definitions by clicking on the link you supplied.

"Note: Please use the information from to decode the Reason and Condition codes."

1. The link is incorrect and points to "" which is clearly not correct.

I looked at for quite a while and could not find the code definitions.

1. Can you supply the Reason Code definitions?
2. Can you supply the Condition Code definitions?
3. Can you explain what the Source ID's is?

Or supply the exact links.

According to the Level II TCP/IP documentation after the date field and time fields are:
Reason Code, Condition Code, Source ID

Here are some sample Level II TCP/IP data lines:

It looks to me like the codes following the date field are numbers.
The link you provided to obtain the definitions of the reason and condition codes
show Letters not Numbers for the Codes.

Am I missing something?

Also, I didn't see any Source ID definitions in the link.
