[amibroker] Re: Help with AD Ratio

Yes it did help very much, thank you Don.  It looks much better and I 
like the adjusted title.  I think the source I was replicating 
normalizes their data, and I'm inquiring as to their process.

Would you know how to plot this same style histogram for an up/down 
volume ratio?  I'm sure it just involves and extra step and I'm 
working on getting the order of operations correct.  Thank you very 
much.
