Volume-weighted Moving Average in SC4

[Ben Anderson <benand@xxxxxxxxxxxxx>]

I am trying to create the easy language formula for the Volume-weighted
moving average indicator that was in the February 2001 TASC. The
following works, (doesn't turn the indicator off when a zero is in the
data field), but that zero creates a big spike down on the chart. Is
there a way to correct the spikes?

IFF (C * V <> 0, (C * V) / V,1)

Thanks for your help, Ben
