Re: [amibroker] Weekly chart indicator for an EOD daily database

You need to use timeframeexpand function to get the weekly to fit the daily chart
eg
wo = timeframexpand(wo,inweekly);

Hi everyone... newbie here.

I have been trying to test Dr Elders formula for Triple screen, for
which there is a AFL formula in the www.amibroker.com/library.

There are indicators provided within the AFL script. However, the
Weekly chart indicator does not work correctly. The OHLC ranges are
not correct and are not displayed by weekdate. See below.

// Weekly Bar Chart
//_SECTION_BEGIN("Weekly Graph");
//TimeFrameSet( inWeekly );
//wo = O;
//wh = H;
//wl = L;
//wc = C;
//TimeFrameRestore();
//PlotOHLC( wo, wh, wl, wc, "Weekly Close", colorCustom9, styleBar );
//_SECTION_END();
//_SECTION_BEGIN("EMA");
//P = ParamField("Price field",-1);
//Periods = Param("Periods", 15, 2, 200, 1, 10 );
//Plot( EMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color",
colorYellow ),ParamStyle("Style") );
//_SECTION_END();

I have been looking for a Weekly chart indicator which displays OHLC
by week in our user group and the AFL library. I can only find a
working monthly created by Graham Kavanagh 26 Dec 2002 in the
amibroker/library (very cool script that uses _javascript_ within the
AFL).

The logic to build this indicator does not seem trivial. Does anyone
have a working version of a Weekly chart indicator which will work on
an EOD daily database? It would be beneficial to display in the
title: weekdate, Open, High, low, close.

Thank you in advance for your help. We should post this indicator so
it is easily available for everyone.
