How to make alerts in real time?

[Aleehatami]

I'm trying to make the AlertMA script that esignal comes with into a real time alert. That is it doesn't wait for a new bar to close above the MA to alert you, it will alert you immediately when it goes above and below the MA. I tried to change BARSTATE_NEWBAR to BARSTATE_CURRENTBAR but that didn't work. I suck at scripting so help would be appreciated thank you.

Here is the script:

if (nState == BARSTATE_CURRENTBAR) {
if(close(-1) >= v) {
if(!bIsLong) {
Alert.addToList(getSymbol(), "Price is >= 10 Bar MA", Color.black, Color.green);
Alert.playSound("swoosh.wav");
