bid/ask volume % indicator, page-4

I thought you might be recording it all on paper.
OK, you have 2 options;

1.Build a custom indictaor in your software. Most packages have the ability to do this. However, they all read data from a quote file, and most quote files work on end of day data. So you need a software package that works on hourly or minute data first.Let me know when you get that far, and i'll show you how to write a custom indicator.

2. Learn to use excel better. I would record this info manually in excel and then use excels chart function to draw charts from your custom formula. If you can get this far, then I'll show you how to get excel to go the webpage and record the info every few minutes AUTOMATICALY.

Option 2 would be my choice. Unfortunatly, theres no fast way to learn excel. You just have to delve into the help files and run google searches on excel help.
