Re: [amibroker] Plot High Value Code Question

["ed nl" <ed2000nl@xxxxxxx>]

Dean,

below I show a kind of "rough" way to do it. One should be able to avoid the loop but I leave that for someone else. This one you can switch to daylay timeframe and then it adjusts the line,

rgds, Ed


TimeFrameSet( inWeekly );

wks = 4;
highOfLastwks = HHV(H,wks);
store = Null;

for (i = BarCount - wks; i < BarCount; i++) {

 store[ i ] = highOfLastwks[ BarCount - 1 ];
 
}

TimeFrameRestore();

store = TimeFrameExpand( store, inWeekly, mode = expandFirst  );

Plot(C,"",colorBlue,64);
Plot(store,"",colorYellow,1);

  Subject: [amibroker] Plot High Value Code Question



  I'm attempting to plot a straight horizontal line on a weekly chart 
  that that uses the highest high of the last 4 weeks including the 
  current week and plots that line horizontally.

  I've tried initializing a variable that finds a max value for the 
  past 3 weeks but my coding doesn't work.

  /* Switch to weekly time frame */

  TimeFrameSet( inWeekly );

  maxhigh = Max(( "H", inWeekly, 0 ),( "H", inWeekly, -1 ),( "H", 
  inWeekly, -2 ),( "H", inWeekly, -3 ));    ***** bad code here ??

  Pd1=Param("EMA 1 Period",5,2,200,1);
  Pd2=Param("EMA 2 Period",8,2,200,1);

  Plot(EMA(C,pd1), "EMA 1",ParamColor( "Color EMA", 38 ), styleThick);
  Plot(EMA(C,pd2), "EMA 2",ParamColor( "Color WMA", 21 ), styleThick);
  Plot(maxhigh,"Pivot",colorBlack,styleLine);

  PlotOHLC( Open, High, Low, Close, "Modified " + Name(),
  colorBlack, styleCandle );






  Any help or suggestions would be much appreciated.

  Thanx & Regards,


  Dean H.
