[amibroker] QuickAFL question

["black_marubozu" <black_marubozu@xxxxxxxxx>]

hello everybody,

I would like to have daily moving averages plot on intraday charts. because AB4.40 doesn't have time frame functions I wrote workaround. it works well on 60 min data bars but the shorter interval, the less dots of daily MA are visible. 

q1: is that because of QuickAFL enabled?
q2: if so, is it true that if QuuickAFL enabled and calculus involves variable that depends on its past values (eg. EMA), the calculus will not be exact from point of required data?

I would appreciate any explanation,
regards,
BM

here's my code:

//detecting last day bar
arrLastDayBar = Nz( DateNum()!=Ref(DateNum(),1) );

j = 0;
arrCloseTmp = 0;
for(i=0; i<BarCount; i++) {
	// if bar is day last bar -> put its close into temp array ("sqeezed" version of Close)
	if( arrLastDayBar[i] ) { arrCloseTmp[j] = Close[i] * arrLastDayBar[i]; j++; }
}

//temp array looks like C0,C1,..,C[lastday],0,0,0...0[lastbar]
//evaluate MA of temp array
arrCloseMA = MA(arrCloseTmp, 20);
//and redistribute result through bars
j = 0;
for(i=0; i<BarCount; i++) {
	// if bar is day last bar -> fill cell of temp array with MA value
	if( arrLastDayBar[i] ) { arrCloseTmp[i] = arrCloseMA[j]; j++; }
	// otherwise put zero there
	else arrCloseTmp[i] = 0;
}

// finally plotshapes
PlotShapes( IIf(arrCloseTmp, shapeHollowSmallCircle, shapeNone), colorBlue, 8, arrCloseTmp, 0);
