Lyle!
I haven't bothered to look this up in the manual but your weights on the vma
are inconsistent. They should sum to one (1). Therefore your weights must be
either 0.078 and (1-0.078) or 0.78 and (1-0.78) .

Subject: Indicator help request
I trying to duplicate the calculation of the variable moving average as
posted on page 489 of the 7.0 manual.
"VMA = (0.78*(volatility index) * close) + (1-0.078 * volatility
index)*yesterday's VMA
The absolute value of a 9-period Chande Momentum Oscillator is used for the
volatility index"
I enter the following indicator:
vi:=cmo( c,9 )
vma = (0.78*(vi) * C) + (1-0.078 * vi)*prev:
vma:
But it does not plot anything like Mov(c,9,var)
What am I doing wrong?
The reason I want to duplicate the variable moving average, is that I would
like to try differnt indicators for the "(volatility index)" part of the
formula.
Thanks
Lyle
