Hello Barry,
Thanks for the suggestions, but that's not the solution for me. I've
only added a couple of tickers yet. If I try to backfill them
individually or all at ones doesn't make a difference. As a rule I
do get this error.
Data does come in. The live feed is fine. So I tend to say it has
nothing to do with a bad ticker. There's only an issue when
backfilling. Even when backfilling some data may come in, but if
this error occurs the backfill is incomplete.
Any other suggestions?
