comparison symbols

[xoprofittaker]

I am trying to creat an EFS study that will apply an equasion to the main chart symbol and the comparison symbol that is loaded on that page. How do I differentiate between the main symbol and the comparison symbol???

Thanks,

John

Hello John,

To access the prices of a symbol external to the chart's symbol, use the sym() function. Most of the EFS Series functions have an optional sym() | inv() parameter. This is where you would use the sym() function. Just pass the external symbol to sym() as a string. For example, the following will retrieve the last price for IBM.

var nIBM = close(0, sym("IBM"));

The series functions will refer to the chart's symbol unless you specify an external symbol with the sym() function. To retrieve the last price for the chart symbol,

var nMySymbol = close(0);

Then you can use the variables in math equation.

var myResult = nMySymbol - nIBM;

myResult would then contain a number that is the result of the current chart symbol's price minus the price of IBM.
