I've been having delayed quotes sometimes for the past two days. TD Ameritrade is my data source. I started MT fresh this morning at 7. I didn't realized I had delayed quotes until I sold my ULTA puts way early this morning because it looked like it was going up. It was more than 5 mins delay. They caught up if I hit Backfill button. They were eventually synced by itself an hour or so into the trading. Anyone else is having the same problem? Thanks.
