Volume scanner

Does anyone here have an intraday volume scanner they like? What I need is a scanner that will tell me when a stock begins to do unusually high volume intra-day.

 

Check out the IB Scanner. It is available for IB customers at no extra charge.

The relevant scan is: Hot Contracts by Volume.

The rank is the volume of the instrument relative to its own average volume.

Where exactly in TWS I should look to find IB scanner?
Thank you.
