nickm,

can I take a look at your code?

personally, I like the comparison to 'bollinger bands' -- bollinger bands do not 'volume weight' each observation. yes, it does matter what volume traded where -- but it can also be argued that 'data outliers' are actually more important when doing statistical analysis -- even if they occur on less volume. but you can argue this either way...

I think unweighted price versus VWAP_H could be a useful indicator...
