RE: [amibroker] Question on nuance of Foreign and SetForeign.

["Terry" <MagicTH@xxxxxxxxxxx>]

I agree with Graham to use SetForeign, do your calcs and Restore since
your BASE is just the CLOSE and does not contain O,H or L data.

However, you can also save OHL if you wish
BASE_O = Foreign("^IXIC","O",1); 
BASE_H = Foreign("^IXIC","H",1); 
BASE_L = Foreign("^IXIC","L",1);
