So if I have two charts open, both 5 minute charts of the same symbol, one displaying regular market hours and one displaying extended session and I draw a trendline alert spanning the last hour right now from 11:20am to 12:20pm I only see it on one of the charts even though the line isn't going through data that isn't available on both charts? See attached, I drew an alert line separately on each chart and it doesn't display on the other.
Thanks
