> To group:
>
> I am trying to compare AAPL to QQQQ over the last 260 trading days.
> Everything works except that I get an error with variable 'x' when

> correct the coding for variable 'x'?

> // CURRENT SYMBOL
> a = Ref(Close, -260); // closing price one year ago
> b = Close; // current price
> perf = b / a; // Performance = current price divided by the current
> price one year ago
>
> // FOREIGN SYMBOL
> x = Foreign("QQQQ", Ref(Close, -260)); // closing price of QQQQ one year
> ago
> y = Foreign("QQQQ", "Close"); // current price for QQQQ
> perf_foreign = y / x ; // Performance = current price of QQQQ divided by
> price of QQQQ one year ago
>
> // RELATIVE PRICE COMPARATIVE
> rpc = perf / perf_foreign ; // compares the current symbol to the QQQQ's
>
> // PLOT RESULTS
> Plot(perf, "ticker", colorDarkGreen, 1); // plot current symbol
