Can I use this?
Does the change printed in the table represent the change from yesterday’s close and today’s open?
change is w.r.t yesterday close but this data is not real time. It is delayed by 3-4 mins
At around 9:07, Pre-Open Order collection ends. I get it at 9:11 but it’s still true change w.r.t. the previous day’s close right?
What can I do to get the gappers then?
Yes. Correct. I use this link to create a list of gap-up and gap-down stocks before the market opens at 9:15 am.
Is there a way to get the volume? What does quantity mean in that table?
