[amibroker] New Highs - New Lows indicator on weekly timeframe

[polomorabe]

Hello,

Thanks to Dennis Skobar's contribution on AB's AFL library, I have the
indcator to calculcate the NH-NL indicator:
  H1 = High > Ref(HHV(High,260),-1);
  L1 = Low < Ref(LLV(Low,260),-1);
  HiLoDifference = H1 - L1;
  AddToComposite( HiLoDifference , "~NewHiNewLoIndex", 
     "X", atcFlagDefaults = 7);

However, on the weekly timeframe, this indicator uses Friday's data
value. Is there a way to specify that it should sum the values for the
individual days of the week when displayed on the weekly timeframe, in
the same way the the volume indicator sums the daily volume values?

Many thanks,
Paul
