new ema() function not same as old?

[Tex50]

Hi again,

Is it me with my double-fast bar replaying computer or is there some reason my charts plot these values differently?

I notice the old style MA study matches the built-in study, but the new ema() function doesn't....


Thanks!

The syntax you are using for the ema() function is incorrect. It should be
myStudy1 = ema(21,low());

As Always, you the best ALexis! It works now!

(thought I tried that... hmmm...)

THANKS!

Hate to bug you Alexis, but one more quicky?

Seems I can't pass an integer variable to setBarxx functions?

This works

setBarThickness(5,0);

This doesn't?

myVar = 5;

setBarThickness(myVar,0);

Even adding myVar1 = myVar.toFixed(0); doesn't work.

setBarThickness(myVar1,0);

Is this true for all setBar functions or do I need to spec some specific kind of var to do this?

I guess it's clear I wish to modify (for instance) bar thickness according to some parameter in my code; the alternative is to paint some object over each bar.


Thanks!

Seems to be working fine. See image below which is the result of the enclosed code
Alex

function main(){

    var myVar = 5;
    var mySMA = sma(5);
    
    if(close(0)>mySMA.getValue(0))
        setBarThickness(myVar,0)
        
    return mySMA.getValue(0);
}

Shortly after posting my last question, eSignal crashed. I started it, reset the Heap and Stack sizes to really high (16384) then restarted it again and now my code works.

Sheeesh, sorry to bug you Alexis, but tons of thanks!

Okay, I'm a dummy or something is terribly wrong with my system.

I figured this would work and it doesn't. It seems the same interval EMA is returned in all cases no matter the interval of the chart.

I'm trying to have an ema that is always referenced to the Daily chart... so far, no joy.

HELP!




function preMain()
{
setPriceStudy(true);
setCursorLabelName("EMA1", 0);
setCursorLabelName("EMA2", 1);

setDefaultBarFgColor(Color.red,0);
setDefaultBarFgColor(Color.green,1);

}

var myStudy = null;
var myStudy1 = null;

var bInit = false;

function main() {
var myVar;
var myVar1;

if ( bInit == false ) {

myStudy = ema(21,hl2());
myStudy1 = ema(21,hl2(),inv("D"));
bInit = true;

}

//retrieve the current value
myVar = myStudy.getValue(0);
myVar1 = myStudy1.getValue(0);

return new Array( myVar, myVar1 );

}
