All Ords Average

[rta]

I am trying to plot the All Ords Average-over the all ords from 1980 to date
Cum(c)/cum(1) works well but the scale is wrong, so
Cum(c)/Cum(1)*power (1.000216966,cum(1)) may work
But no, "POWER"-- "must contain only constant data"
Any ideas??

Cum(C)/Cum(1) is correct if you want the real All Ords avg, but perhaps a 252-period simple or exponential moving average may be closer to what you're after.
