As of the morning of Feb 11 (Thur) SC now has the ability to show extended hours. I have been watching EH on my IB charts, but this will be something new to see if I want to incorporate into my normal trading. EH has historical not been that reliable as to the trend in place. But I am glad to now have the information on the SC.
The box to click for EH is just to right of Zoom Thumbnails box.
Trade the Charts and not the Heart - Expect the trend to continue until it doesn't - Realtime is the real deal
