sometimes it plots what it is suppose to and

sometimes it doesn't,

it plots in some intervals and in some not.

do you have any idea what could that be?

have a great day...

In general that would indicate some logic error in the script. However without seeing the code it is not possible to determine where this error (if any) may be and/or how to correct it.
In order for someone to be able to offer some guidance you will need to post the script

THANKS A LOT FOR YOUR HELP,

HAVE A GREAT DAY.

Hello jaimeog,

There aren't any problems with your formula code. Your alert conditions are just very restrictive. I ran this on 20 days of 1-min data on ES #F and only receive 13 signals.

To see where the signals are occurring it would help to plot the hhv() and llv() series that you are using in your conditions. Then in your onAction functions add the following debugPrintln() statements so you can see which historical bar indexes are triggering the alerts. Be sure to open your formula output window (Tools-->EFS).

function onAction1() {
    if (vLastAlert != 1) {
        debugPrintln("Bar: " + getCurrentBarIndex() + "  Enter Up!");
        Alert.addToList(getSymbol(), "ENTER UP", Color.RGB(0,0,0), Color.RGB(195,0,0));
    }
    if (vLastAlert != 1) drawShapeRelative(0, high(), Shape.CIRCLE, "", Color.RGB(155,0,0), Shape.TOP);
    
    vLastAlert = 1;
    
}

function onAction2() {
    if (vLastAlert != 2) {
        debugPrintln("Bar: " + getCurrentBarIndex() + "  Enter Down!");
        Alert.addToList(getSymbol(), "ENTER DOWN", Color.RGB(0,0,0), Color.RGB(195,0,0));
    }
    if (vLastAlert != 2) drawShapeRelative(0, low(), Shape.CIRCLE, "", Color.RGB(155,0,0), Shape.BOTTOM); 
    
    vLastAlert = 2;
    
} 

P.S. By the way, typing in all caps is perceived by many as shouting. The tone of your message certainly did not convey shouting so just thought I'd let you know.
