This is a serious error because it changes important support and resistance like yesterdays close price and important intraday moving averages.
I was under the impression that RTH trading hours was actually: 0830 - 1515 CT
However according to one of the links above they changed the end time to 1500.
Tbh I'm not sure whether I should be looking at 1500 or 1515.... but it definitely is not 1600.
