Help exploration volume

[Bruce Waller <waller@xxxxxxxxxxxxxxxxx>]

All,

I would appreciate any assistance in adding a volume parameter to an
exploration, is anyone able to help with how it may be written.

The aim is to include a volume parameter which will reject stocks with
an average volume below a certain level over X amount of periods.
Eg.  "existing exploration" AND " proposed volume bit "

Thanks in advance
Bruce Waller
