I have databases (intraday and EOD too). I want to make these steps: a) delete all quotations for all symbols b) backfill all symbols again.
I do now want to delete ticker files in database directory as I have annotations (trend lines etc) on a lot of charts and I want to keep them in database What is best way to do steps described above (especially deletion of data for each symbol but preservation of annotations)? Thank you for your advice Ric
