TRTHv1 and DSS - Intraday request - different results

Philipp
Philipp Contributor

I'm running to test cases, or more precisely the same test case against TRTHv1 and DSS. The goal it to get exactly the same results. I now have the strange situation, that I'm getting more results from DSS then via TRTHv1 in the time before 8 am (from 08:00:04 on the results are 100% matching). Example below. Can you please explain why this is happening? I can verify this behavour using the TRTHv1 WebInterface and DSS with the PostMan examples.

TRTHv1:

    Hi Philipp

    There are expected differences in timebars data generated in v1 and v2.

    Timebars in v1 were over-simplistic in nature. It included all kinds of trades in summary i.e. regular trades, off-book trades, delayed trades, etc.

    Timebars in v2 are governed by market-specific rules. Off-book trades, delayed trades, etc are not necessarily chartable and thus not included in summary. Only regular automatic trades and auction trades are taken into summary. v2 summaries are a more accurate reflection of orderbook state so to speak.
