Drawing Shapes and ticki

[dangparker]

Hi again,

Chart set up: 135t ES Z3

Trying to do: Draw a dot at the high (+.25) of a bar when $ticki>=22

This is the code I wrote:

function preMain() {
setStudyTitle("tickidots");
setPriceStudy(true);

}
var n=1
function main() {

//get $ticki value
var thigh = high(0,"$ticki");

//draw shape
if (thigh >= 22) {
drawShapeRelative(0,high(0)+.25,Shape.CIRCLE,null, Color.lime,Shape.ONTOP,"high"+n);
n=n+1;
}

return;
}

I get "Loading Data" and nothing else on the chart.

Any suggestions?
Thanks
Daniel Parker

Seems to work on a 1min chart, but not a tick chart.

Hmmm....stumped....

I think the documentation for drawshape is a little misleading, try this

function preMain() {
setStudyTitle("tickidots");
setPriceStudy(true);

}
var n=1
function main() {

//get $ticki value
var thigh = high(0,"$ticki");

//draw shape
if (thigh >= 22) {
drawShapeRelative(0,high(0)+.25,Shape.CIRCLE,null, Color.lime,Shape.ONTOP);
n=n+1;
}

return;
}

I ran the code this morning....

Every bar gives me a ticki high and plots a dot! I know this is not the case in reality.

One thing, ES updates every tick (135t chart), and the efs runs everytick, right?

But $ticki only updates every 6 seconds or so, could this be part of the problem?

Has anybody gotten this to work?

Your help is much appreciated

Hello dangparker,

This routine will not work on a 135t interval because the 135t bars of $TICKI do not correspond with 135t bars of ES based on time. The formula should work fine on time-based intervals (i.e. 5 minutes, daily etc.).

[dangparker]

So is there a way (command, overlay, whatever), to get the current value of $ticki on a 135t ES chart?

Thanks for your help,

Hello Daniel,

There isn't a way to synchronize this overlay on historical data because we do not have access in EFS to historical time and sales data. The code example below will collect the $Ticki data in real time and should give you the result you need. Keep in mind that when you first apply this to your chart, you won't see any shapes drawn on the historical bars. From that point on it will collect and draw the shapes.

function preMain() {
    setStudyTitle("tickidots");
    setPriceStudy(true);
    setShowCursorLabel(false);
} 

var tHigh = null;
var tLow = null;
var n = 0;

function main() {
    if (getCurrentBarIndex() != 0) return;

    var tLast = close("$TICKI");
    if (tLast == null) return;
    
    if (getBarState() == BARSTATE_NEWBAR) {
        tHigh = tLast;
        tLow = tLast;
        n += 1;
    }
    
    tHigh = Math.max(tHigh, tLast);
    tLow = Math.min(tLow, tLast);
    
    if (tHigh >= 22) {
        drawShapeRelative(0,high(0)+.25,Shape.CIRCLE,null,Color.lime,Shape.ONTOP, "high"+n);
    } else {
        removeShape("high"+n);
    }

    if (tLow <= -22) {
        drawShapeRelative(0,low(0)-.25,Shape.CIRCLE,null,Color.red,Shape.ONTOP, "low"+n);
    } else {
        removeShape("low"+n);
    }

    return;
}

Thanks for the coding help, I was able to figure out that ticki close (and not high or low) was what I needed to look for.

Attached is the file I came up with, a bit cludgy buy it works (and moves the dot if the high pushes through the high on which the ticki dot formed (for the same bar).

Hope it can be of help to someone.

Thanks again for your excellent support

p.s. If someone comes up with a way to streamline my efs, feel free to post it back here
