Bad data on QLGC on 21 Nov

[Mephisto]

Hi

Something strange is happening to my charts resulting in them sometimes producing wrong charts.

Today on QLGC I noticed what I thought was an Opening Reversal which subsequently failed, notice how the 5th bar for today exceeds the 1st.

Then others (who are also using eSignal) said they didn't have an Op Rev on their charts.
I exited and then reloaded the chart and suddenly noticed they're correct, the 5th bar is now LESS than the 1st.

What's happening here.

Please note this is not the first time either.
