If I don't leave NT running through the night, sometimes in AM when I connect to Barcharts I get pre-market data but most times I don't. It always disappears after symbol change.
Example attached.
You can see pre-market data on SPY, switched to QQQQ, no pre-market data and switch back to SPY and the pre-market data is gone also. All times on charts are Mountain Time.
If I disconnect from Barchart and exit NT with pre-market data on screen, when NT is restarted and Barchart is reconnected, pre-market is still on screen and if we are still in pre-market hours, it will update pre-market bars.
After hours I have never seen more than 2 bars on any timeframe.
Any reason why pre-market data only shows if NT is left connected through the night and why does it disappear on symbol change? I am also wondering should it be showing after hours data?
