efs coding for "or"

[TURLIES]

Hi,

This efs prgramming works fine when drawing a line on an individual basis for each x-rate:

if ( sSym == "JPY A0-FX") {
drawTextRelative..............
}

if ( sSym == "EURJPY A0-FX") {
drawTextRelative.....................
}




To simplify things, is the following efs coding possible, so i can add as many x-rate symbols as i need into one line of coding:

if ( sSym == "JPY A0-FX or "EURJPY A0-FX" or "CADJPY A0-FX") {
drawTextRelative..............
}


Thanks,
Paul

Hi Paul,

Find info on logical operators at:

Specifically, try:

if ( sSym == "JPY A0-FX" || sSym == "EURJPY A0-FX" || sSym ==  "CADJPY A0-FX") {
drawTextRelative..............
}

Paul,

There are several ways to do what you want with JavaScript (the language EFS uses). Some of them are:

- Use a logical OR ("||") as Wayne has shown.
- Put the strings you want to match in an array and scan the array, testing for a match.
- Use a regular expression to test part of the string for a match.

Since it seems what you want is to detect any string ending in " A0-FX", a regular expression would do what you want, detecting ANY symbol ending in " A0-FX":

var isSymAMatch = false;
var endingStringToMatch = " A0-FX";

function main() {
    if (getBarState() == BARSTATE_ALLBARS) {
        // Test the end of the symbol to see if it matches:
        // (No need to do it on every call, just do it on ALLBARS.)
        var re = new RegExp( endingStringToMatch + "$", "i" );
        isSymAMatch = re.test ( getSymbol() );
    }

    // print out the result on every call, as if doing real processing.
    if (isSymAMatch) {
        debugPrintln( getSymbol() + " ends in [" + endingStringToMatch + "]" );
    } else {
        debugPrintln( getSymbol() + " does NOT end in [" + endingStringToMatch + "]" );
    }
} 

The "$" means the match must occur at the end of the string. The "i" means it is case insensitive (lower or uppercase doesn't matter).

If you want, you could probably replace " A0-FX" with just "-FX" in the code above.

Hi wayne and shortandlong,

I wanted to have different text displayed for Japanese Yen X-Rates only, so I have used the logical OR ("||"), which has worked great and saved me a lot of time and effort.

Many thanks,
Paul
