I retrive both Elektron TimeSeries and Tick History Time and Sales data from 2013-12-06, but some rics not found in Tick History on some dates.
For exsample, records before 2017-09-13 for FEI.AX are not included in Tick History, while TimeSeries contains data with Volume>0 and date<2017-09-13
Same problem for ARV.AX between 2017-02-03 and 2017-02-10
How can I get tick data during those periods?
Thank you very much for sharing additional information. That helped in clarifying the issue. Based on my findings I can infer that the entity in question underwent several RIC changes historically, and <FEI.AX> is the current RIC, which was added on Tick History from 09/12/2017 onward. To be able to see the historical data for the entity I would advise you to use the Historical Reference Report from Tick History. This report will you give detailed information about all the previous RIC changes mapped to the entity and the respective start and end dates using which you can plan to query the data.
See enclosed a screenshot of the report and the fields which you can use while running the Historical Reference Report.hist-ref-report.png
I investigated the issue for <FEI.AX> and below are my findings:
1). We have historical data for the RIC <FEI.AX> from 09/12 onward in Tick History. When I say historical data I refer to all data points (including quotes) and not just trades.
2). It appears that you only used the "Trade" fields while querying the data and there were no trades between 09/12 and 09/15, but only quotes (Bid/Ask). But as you only seemed to have used the Trade fields the query failed to capture the quotes and thus returned no data.
3). If you can add "Quotes" fields too in the query then you should be able to get the quotes data between 09/12 and 09/15.
As an additional information, <FEI.AX> is suspended from Official Quotation effective 3 December 2018, following failure to lodge the relevant periodic report by the due date.
