[amibroker] optimizing trades based on a foreign CCI not working as expected

["Dave Merrill" <dmerrill@xxxxxxx>]

can anyone tell me why these two tests give the same results for every index
I tried?

both versions go long and short based on a CCI, optimizing for best returns.
version 1 uses the CCI of the issue under test, and version 2 uses the CCI
of another index, I thought.

but I get the same results no matter what foreign index I use, including
contrarian ones like the VIX you see below.

what am I missing?

thanks,

dave

VERSION 1
----------------
period = Optimize("period", 2, 1, 100, 1);
threshold = Optimize("threshold", 25, 0, 100, 25);

cc = CCI(period);

Buy = Cross(cc, threshold);
Sell = Cross(-threshold, cc);
Short = Sell;
Cover = Buy;


----------------
VERSION 2
----------------
period = Optimize("period", 2, 1, 100, 1);
threshold = Optimize("threshold", 25, 0, 100, 25);

saveO = O;
saveH = H;
saveL = L;
saveC = C;
saveV = V;
O = Foreign("!VIX", "O");
H = Foreign("!VIX", "H");
L = Foreign("!VIX", "L");
C = Foreign("!VIX", "C");
V = Foreign("!VIX", "V");
cc = CCI(period);
O = saveO;
H = saveH;
L = saveL;
C = saveC;
V = saveV;

Buy = Cross(cc, threshold);
Sell = Cross(-threshold, cc);
Short = Sell;
Cover = Buy;
