I have an information for RIC change from CBG.N to CBRE.N on 2018-03-20 as shown below.
I could get ElektronTimeseries data for CBRE.N from 2018-01-01 to 2018-02-01 whereas no data for CBG.N during the same period. This is fine.
On the other hand, when I requested a TimeAndSales for CBRE.N for 2018-01-01 to 2018-02-01, I've got NO data. Neither did I get any data for CBG.N during the same period.
How can I retrieve TimeAndSales when RIC changed?
