I just noticed a very important discrepancy in how data is presented by a NT8 chart (I noticed this on a daily bars chart, and am not sure whether this happens for other timeframes as well or not).
It seems that in some cases, the previous day's bar has current day's timestamp on it, and all previous bars have also the day offset by +1.
I am enclosing screenshots taken at the same time: one of the NT chart with the data box showing the date and the ohlc values, one of the same from TWS (I use IB exclusively), and one of Yahoo Finance for the same symbol (ABB).
As you can see from the screenshots, the issue is present only in the NT chart, and not in TWS, which displays the correct date for the last bar. The Yahoo screenshot is included just for completeness so that there be no doubt the data in TWS is correct, and that the problem comes from NT.
This only happens for some instruments, and not for others (in fact, most are correct).
In case this is important, I took the screenshots on Thursday, July 13th, 2017 at 12:30 PM in the Prague, Czech Republic time zone,
i am hoping this is just a glitch coming from some misconfiguration. If it is not, though, this could potentially be a huge issue for all and every trader.
Many thanks,
Libor
