Alert only 1 Time ?!

[erilein]

var study = new MAStudy(2, 2, "OHLC/4", MAStudy.EXPONENTIAL);

function preMain() {
setPriceStudy(true);
}

function main() {
var v = study.getValue(MAStudy.MA);

if(v == null)
return;


if(close() >= v) {
Alert.email("es geht hoch", "HOCH!");
vLastAlert = 1;
Alert.addToList(getSymbol(), "Es geht Aufwaerts", Color.black, Color.green );
if(!Strategy.isLong()) {
Strategy.doLong("Aufwaerts!", Strategy.MARKET, Strategy.THISBAR);

}

} else {
Alert.email("es geht runter", "RUNTER!");
vLastAlert = 1;
Alert.addToList(getSymbol(), "Es geht Runter", Color.white, Color.red );
if(!Strategy.isShort()) {
Strategy.doShort("Abwaerts!", Strategy.MARKET, Strategy.THISBAR);
}
}

if(Strategy.isLong()) {
setBarBgColor(Color.green);
} else if(Strategy.isShort()) {
// setBarBgColor(Color.red);
}


return v;
}

When i run this formula i get a signal every minute ... but i want the script to give signals only at changingpoints ...

(Buy Put , Buy Call) at this time there is Call , Call , Call, Call , Put or so...

please help

Try the enclosed revision
As an aside you may also want to try using the Formula Wizard which can greatly simplify making efs like these.

var study = new MAStudy(2, 2, "OHLC/4", MAStudy.EXPONENTIAL);
var vLastAlert = -1

function preMain() {
setPriceStudy(true);
}

function main() {
var v = study.getValue(MAStudy.MA);

if(v == null)
return;


if(close() >= v) {
if(vLastAlert!=1)Alert.email("es geht hoch", "HOCH!");
if(vLastAlert!=1)Alert.addToList(getSymbol(), "Es geht Aufwaerts", Color.black, Color.green );
vLastAlert = 1;
if(!Strategy.isLong()) {
Strategy.doLong("Aufwaerts!", Strategy.CLOSE, Strategy.THISBAR);

}

} else {
if(vLastAlert!=2)Alert.email("es geht runter", "RUNTER!");
if(vLastAlert!=2)Alert.addToList(getSymbol(), "Es geht Runter", Color.white, Color.red );
vLastAlert = 2;

}


return v;
