Historical charts continue to update after market close

[Benji]

My daily/weekly/monthly historical charts are all updating in real-time with extended hours stock quotes. I have "Never" selected for "Extended hours" in settings under Charts/General, and all my intraday charts are currently set the same way. The intraday charts are working as expected.

that setting is for intraday charts.

for historical charts the last bar is built from the OPEN, HIGH, LOW, LAST as shown on the portfolio. It does not look at intraday data at all, which is what would be needed if we were to have to get the data earlier than the LAST.

Is there any way to get the historical to stop updating in extended hours? Even if I "stop" my portfolio windows, the values continue to update.

The issue is the value being updated for "close" in today's candle is not correct. This will be obvious when I clear and backfill tomorrow as the value will get corrected to the proper market close. I've tested just about every possible charting application and I can't say I've seen one that works this way. RTH/Extended hour toggles make sense for intraday charts, but for daily/weekly/monthly usually they're fixed to regular market hours.

[Jerry Medved]

only way is to turn off real-time updates for historical charts.

Right, that is my workaround. I'll just need to toggle daily at market open & close. My ideal option would be "Real-time Updates for Historical Charts During Regular Trading Hours".  Are there any plans for settings to be exposed in the API?
