Count Array length in Amibroker. One of the most frustrating aspects when starting out with AmiBroker is being able to count an array's length. To execute this function simply paste the two functions into your code and whenever you want to count the length of an array simply call arrCount( yourArray );

countArray.ab

EnableScript("JScript");

<%
function getArrayLength( a ) { 
	x = VBArray( a ).toArray();
	for ( y = 0; y < x.length; y += 1 ) {
		if ( x[y] == undefined ) break;
	}
	return y;
}
%>

function arrCount( arr ) {
	scr = GetScriptObject();
	a = 0;
	if ( !IsNull( BeginValue( arr ) ) ) a = scr.getArrayLength( arr );
	return a;
}
