When I request a list of all available Market Places, I receive a huge list. There a few records for NASDAQ, for NYSE, etc. And it looks like not all of those sections are actually required.

How can I merge them to unique one?

For example, at your site
http://www.iqfeed.net/symbolguide/index.cfm?symbolguide=lookup&displayaction=support§ion=guide&web=iqfeed&alpha=1&start=1

the list of exchanges is much shorter.

Is there some 'standard' way to do this?

Hello,

This is something we will be adding in the next version of IQFeed. Currently, mapping the various markets is a manual process, but to save you some of that, below is the return showing the soon to be new result.

You can see below in the fourth field, that you will get the parent listed market. So, as an example, all markets that are under Nasdaq have a parent id of 5, which I think meets your need. Just make sure to get it back to a dynamic pull of the market list when you upgrade to the 5.2 protocol as this will deprecate quickly.

Thanks for the list.

Since I can not set protocol to 5.2, I have to hardcode this info, have I?



Also I see some inconsistency in this sample. I.e. lines
5,NASDAQ,Nasdaq,5,NASDAQ,
14,OPRA,OPRA System,14,OPRA,
34,CME,Chicago Mercantile Exchange,34,CME,
etc.
have circular reference to itself.

But other lines like
8,CHX,Chicago Stock Exchange,0,NONE,
12,BX,Boston Stock Exchange,0,NONE,
etc.
have the mark 'NONE ' which clearly states it is the top-most section.


I feel it is better to use one convention for all cases (I'd prefer with 'NONE' marker)...

For now, I am afraid that is correct. But, the format of the 5.2 return will be the same as what I have sent you, so you should not have to reinvent much, but the data source providing you the list.

Exchanges that have a group, and are the parent of that group, will show themselves as the parent.

Exchanges that have no group members, will just show NONE as the parent.

I will ask about this though and see if the server team wants to make these singletons more consistent with the others before release.

I'm affraid I did not make my situation clear.

I have hardcoded this market tree, but this didn't affect the problem.
For ticker MSFT I still receive trades from EDGA, EDGX, BATS, NYSE_ARCA, BX, etc.

Despite these markets were not marked as 'NASDAQ sections'.

So I must throw away all market structure and use only security types instead of 'markets' or to add even more heuristics to merge all trades of MSFT to a single data stream.

Those are market centers that you are looking at, if you look at Listed Market, that might be what you are looking for?

Just to make things much more weird, I'd like to mention futures @ES# and @ESZ15 from section CMEMINI (ID:43) of exchange CME (ID:34).

After subscribing to these tickets with commands 't@ES#' and 't@ESZ15' I'm receiving the following Update Messages:
Q,@ES#,22,43,1993.00,1,05:55:58.765,1992.75,62,1993.00,55,1991.50,1996.50,1989.25,1994.00,-1,-0.000501505,104279,7538601,,2883659,10/14/2015,05:56:16.958,05:56:16.958,Cbasohlc,01,

field #3 is ExchangeID (it is 22:CANTOR )
field #4 is MarketID ( it is 43:CMEMINI )

So I receive updates for futures @ES# and @ESZ15 of market CMEMINI of exchange CANTOR! This makes me a little bit crazy.

Is it possible this is some kind of a bug in data translation?..

I have verified the situation with your utility IQMarketDepth.exe.
