Tick Size

[waynecd]

Is there a way to get the tick size of the underlying (i.e., 0.25 for ES #F) without creating a series (too inefficient and I can't "grab" the value for use in a script).

I found the attached efs that correctly plots the tick size to the output window but it creates a series using min() so it produces many other price values.

In effect I haven't been able to use the tick size by any means I tried (like .getValue(0) or getValue(-!)).

Thanks in advance for any help.

var nBarCounter = 0;
var z = null;

function main(){
     if ( getBarState() == BARSTATE_NEWBAR ) {
        nBarCounter ++;
     }
    if (getCurrentBarIndex()<-3 && nBarCounter>3) z=Min_Move();
    return z+" ";
}

var mMove=1000;

function Min_Move(){

    var cDelta = Math.abs(close(0)-close(-1));
    if (cDelta) mMove = Math.min(cDelta,mMove);
//    debugPrintln(mMove);
    return mMove
}

FWIW min() is a method of the Math Object and does not return a series.

Alex,

I meant that the:

function Min_Move(){ returns a series and min() is used within it to calculate the return value.

Any ideas regarding how to get the tick value?

The call to the function Min_Move does not create a series but a value. In fact you are not able to retrieve the value returned by it using the getValue() method
You can use the getMinTick() function (see the EFS KnowledgeBase for the description of the function)
