[amibroker] What is your favorite Volume based indicator, or...

[Ken Close]

more generally, how do you best use volume in determining setups and trades?
 
After years of working with the FastTrack data source, which does not have
volume, I am branching out into ETF and even stock analysis and want to add
Volume to the mix....because I am finally able to.  But I find that I am
starting from ground zero in terms of what are popular volume-based
indicators and other useful ways to use volume.
 
Care to share an indicator or two that you have found useful and effective?
 
I appreciate any suggestions.
 
Thanks.
