Yes but I am under the 200 symbol limit in my
watchlist and using only 100 days of EOD data. Many
stocks are showing only a few bars of data. Even with
the backfill checked. Am I supposed to go through all
the symbols one by one and force Backfill?
That would take a long time. Is there no other way?
Why isn't the forced backfill working?
