2024.2 - Allow a Start date when switching from Telekurs to Exshare

There are 2 data feeds of securities data available for use with Trust Accounts and SecTAX, the Exshare Data Feed from ICE and the Telekurs Feed from SIX. Sometimes users wish to switch from one data feed to the other. There is a complication in doing this. Both feeds contain details of events which have been announced but have not yet occurred. If a user starts running the new feed on say 01/01/2024, then there will already be events present from the old feed after this date and when the new feed is run it will duplicate them.

To avoid this problem, when the Telekurs feed was introduced, a Telekurs Start Date was added to Database Parameters. If the user knows in advance that they will be switching from the Exshare feed to the Telekurs feed on 01/01/2024 then that is entered as the Telekurs Start date. Now when the Exshare feed is run before 01/01/2024 the program will not read events or prices after 01/01/2024, leaving them to come from the Telekurs feed. Equally, when the Telekurs feed is run after 01/01/2024, and events prior to 01/01/2024 are not read, since they will have come from the Exshare feed. (This would also apply to prices if there were any old prices after 01/01/2024).

The Telekurs Start Date helped a user switch from the Exshare feed to the Telekurs feed, but it did not work in reverse. This new change is to replace the Telekurs Start Date with 2 new settings in Database Parameters for Changing Data Feed:

• No change/To Exshare/To Telekurs. These radio buttons describe what change is being made.
• New feed start date. This field is available if Changing Data Feed to not set to No Change

Using these settings works in exactly the same way as the Telekurs Start Date, but enables a switch from Telekurs to Exshare as well as from Exshare to Telekurs.

Some other obsolete options have been removed from the Database Parameters at the same time.
