I would not recommend using Tidal to schedule any jobs on Gallery. There was a pilot which was using Tidal and it caused every job subsequent to the Tidal run to fail.
A workaround would be to add logic to your workflow and only export records if the criteria is met. Schedule the job to run daily on the server, then for example the 5th business day roles around, the data will be exported. Add this test step early to alleviate unnecessary processing.
