This is my first time exploring the Market Statistics available from IQFeed. Finally figured out the way to get them via API was to request a 5-minute snapshot (this is neither explained in the docs that I could see nor intuitive to someone new to the API, by the way).

Now, when I use the website search page, I find there are 752 Market Statistic codes results returned (and all of them under "Exchange" DTN). Yet, when I make a 5-minute snapshot request via API v6.2 for the security type code for Market Statistics and the exchange code for DTN, my system receives a file with 3383 lines returned. Are there actually additional types of Market Statistics available via the API? Or what else explains the difference between these two counts?

Mark,

When I use the page https://ws1.dtn.com/IQ/Search/# and select exchange DTN and security type Market Statistic, I get "Displaying records 1-250 of 3381." When I send command 5MS,7,27 I get 3442 symbols in the response. I don't know why your search turned up 752.

The discrepancy between 3381 and 3442 I can't explain. Symbols are added and deleted all the time, and I don't know how up-to-the-minute the search is. There shouldn't be any major differences in the number of symbols you can get via different sources. If your account has access to an exchange, it is entitled to all the symbols therein.

Thanks for the reply. User error caused the low count on the web page. I had accidentally typed a single character into the search box which I hadn't noticed.

OK, that makes sense. The lookups should be more or less complete lists of all the symbols you can get.
