"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available.

Hello,

I'm trying to figure out how to interpret news headlines from iq feed with matlab. Below are some examples from AAPL which I just pulled.

I would like to know what the 3 letters are the start of the string correspond to. Quickly scanning the AAPL items I've noticed the codes, CPR, RTC, RTB, CBW. What do they mean and where can I get more information on them?

'N,CPR,21538147367,:AAPL::OCR::TRV::EOG:,20140605070145,Equities Marking a New High -- Research on Apple, Omnicare, Travelers Cos, and '

'N,CPR,21537839723,:NXTD::GOOG::EBAY::TWTR::AAPL::V:,20140604083151,The Mobile Payment Revolution - Smartphone Apps From Square to Wocket(tm) ; How '

'N,CPR,21537526814,:AAPL::BIIB::TSLA::XONE::R:,20140603093147,Critical Alerts For Tesla, Apple, Ryder System, ExOne, and Biogen Idec Released '

'N,RTC,21537507805,:AAPL:,20140603080956,Apple Unveils IOS 8, OSX Yosemite'

'N,CBW,21535989635,:AAPL:,20140528163022,Apple to Acquire Beats Music & Beats Electronics'

The 3 letter codes are news sources, but I am not sure if Matlab exposes their descriptions to you within their API. The request you want to make is what we call a news configuration request, but I would suggest asking Matlab for the details regarding how this works within their API.

In case anyone else has the same issue: I believe that the news configuration information is not available via Matlab's Trading Toolbox.

If you are using the IQML (IQFeed-Matlab) connector instead of Trading Toolbox, you can query the news configuration as follows:
Quote:
>> data = IQML('news', 'DataType','config')
data =
Category: 'All News'
Majors: [1×7 struct]

>> {data.Majors.Source}
ans =
1×7 cell array
{'DTN'} {'CPR'} {'CBW'} {'RTT'} {'CPZ'} {'CIW'} {'BEN'}

>> {data.Majors.Description}
ans =
1×7 cell array
{'DTN News'} {'PR Newswire'} {'Business Wire'} {'Real-Time Trader'} {'GlobeNewswire Inc'} {'Marketwire'} {'Benzinga Pro'}

You can also drill-down for details about news sources:
Quote:
>> data.Majors(1)
ans =
Source: 'DTN'
Description: 'DTN News'
AuthenticationCode: '1D'
IconID: 10
Minors: [1×4 struct]

>> data.Majors(1).Minors(1)
ans =
Source: 'DT5'
Description: 'Treasuries, Most Actives, Gainers, Losers'
AuthenticationCode: '1D'

>> data.Majors(1).Minors(2)
ans =
Source: 'RTL'
Description: 'Derivatives - Selected Futures and Options'
AuthenticationCode: '2Ab'
IconID: 10
