[amibroker] Limiting action to only once per bar

["wolfie125" <lurama125@xxxxxxxxx>]

Hi, I have an indicator that basically plots the number of contracts i need to be long or short. When the number changes for a new bar, i want to run a piece of code, let's say a messagebox, or a little external program, but what is happening is once the new bar comes and the number of contracts changes this code keeps on executing 100's of times till the next bar arrives. I have tried setting a boolean variable but no success. I specifically dont want to use the alert function as i am already using it for something else on that bar.

can someone help pls, the basic logic currently is something like this :

if ((Lasttweet == False) AND LastValue(xxxtotal)!=LastValue(Ref(xxxtotal,-1)))){

txtmsg = WriteIf(xxxtotal>Ref(xxxtotal,-1),"Just Bought "+ (xxxtotal-Ref(xxxtotal,-1)) + " contracts at " + ppp,"Just Sold "+ (Ref(xxxtotal,-1)-xxxtotal) + " contracts at " + ppp);
PopupWindow(txtmsg,NumToStr(LastValue(pebstime))+" ",100,-1,-1);

Lasttweet = true;	
	
}
