In TimeAndSales request,
I don't really understand meaning of "ContentFieldNames". What is "Auction", "Correction", etc?
I am no economist, so please, do you have anything that would be helpful?
Please refer to DATA DICTIONARY - CUSTOM REPORTING FOR TICK HISTORY 12.1 describing TRTH content. TRTH data dictionary covers all the fields available, per template, including Time & Sales fields.
If it does not fully answer your question, if you'd like to get further detail on specific content, the most efficient way to get answers from TR content experts is via myaccount.thomsonreuters.com or by calling your local Thomson Reuters help desk.
@mihanix.it, as stated by Zoya, the short definition in the Data Dictionary should give you a basic idea of what individual fields are.
We do not deliver a more generic dictionary of financial terms and concepts, but there are many books and web sites you can use to learn them. As an example, here is a description of the LSE closing auction, which is used to determine the closing price of stocks.
