I'm tyring to use variable for the sym()

[mbluhm]

I'm trying to use a variable to put in for another symbol and time frame in a stochD study. The following works if I hard code it:

vStoch10 = stochD(6, 3, 3, sym("IBM, 10"));

but if I try to use a variable

var sym_time = ""\sym(\"IBM,10\")\""

which puts in the sym_time variable

sym("IBM,10")

so the following doesn't work

vStoch10 = stochD(6, 3, 3, sym_time);

with no error message. I've tried just to put in the "IBM,10"

vStoch10 = stochD(6, 3, 3, sym(sym_time))

again without any error message, it just gives bad data. Am I doing something wrong?

Thanks,

Here is a basic example of how to make the symbol and interval a variable for use with the sym() function

var xStochD = null;
 
function main(){
 
    var Sym_Int = "IBM,10";
    
    if(xStochD==null) xStochD = stochD(6,3,3,sym(Sym_Int));
    
    return xStochD.getValue(0);
} 

If you then want to make the symbol and/or interval user defined variables that you can modify through Edit Studies then see the example enclosed below. You may also want to look at the formulas included in the EFS2 Custom folder as they will provide you with examples of how to do it using the FunctionParameter Object

var xStochD = null;
 
function main(Symbol, Interval){
 
    if(Symbol==null) Symbol = getSymbol();//if no symbol is input use chart symbol
    else Symbol = Symbol;//else use input symbol
    if(Interval==null) Interval = getInterval();//same for interval
    else Interval = Interval;
    var Sym_Int = Symbol+","+Interval;//combine symbol and interval as a string
    
    if(xStochD==null) xStochD = stochD(6,3,3,sym(Sym_Int));
    
    return xStochD.getValue(0);
}
