I am wanting to create a composite of a group of tickers by adding the
change of the price day to day
I have tried it the simple way of just
Addtocomposite(c-ref(c,-1), "~index", "C");
etc for OHLC
Addtocomposite(1, "~index", "I");
Then to create the chart by just using Foreign function then Cum(C)
But I found the resulting chart changed too much when I viewed it from each
stock on the list due to, I guess, the starting point varying according to
the base ticker I am viewing from
What I think I need to do is create a composite, then read in the values
from this composite to create a second composite which has definite arrays
that require no further modification to plot
But I am not certain how to do this in a single scan
A simplified procedure below, but I am not sure how to get it to work
Addtocomposite(c-ref(c,-1), "~base", "C");
-? - what can I do here ?
newC = Foreign("~base","c")
myC = cum(newC)
Addtocomposite(myC,"~index","C") etc
Any suggestions appreciated, or reference to another post made, as I cannot
find what I am looking for
I have simplified the formulae above as too lazy to fully type out
everything in the brackets or check if correct, it is the procedure I am
needing.
Cheers,
Graham
