Allan,
Graph0 is old code.
I am using the following to plot the ATC's with success.
PlotForeign("~MyDJI", "~MyDJI", colorBlack, style=styleLine);
Plot(Foreign("~MyDJI","C"),"~MyDJI",1,8);
The later is courtesy of a Dimitri Tsokakis post, although it is
common code.

> The formula above does not give me the OHLC format i want,but it
does use the count as the divisor..What I fail to understand is what
exactly ATC does.I read that it sums the prices.If that is true,and
I do NOT implement a divisor,who can the ATC return a composite
value of 167 for the Energy Sector when there are probably 400
energy stocks..I am pretty sure the average price of an energy stock
is not $2,so how could the sum be 167??
