hello
i am trying to plot a chart like below. but i get a flat line for trin 
and nasdaq. How can i change to make it happen.

my formula
Plot(Close,"nasdaq",styleLine|colorOrange|styleOwnScale);
ForeignSYMBOL=Foreign("NASTRIN.Z","Close") ;
Plot(MA(ForeignSYMBOl,10),"Nasdaq Trin", 
styleLine|colorPink|styleOwnScale);
