Re: [amibroker] Intraday - Open 10 Minute Price Marker

["Edward Pottasch" <empottasch@xxxxxxxxx>]

this version works without the plugin:

 

SetBarsRequired(10000,10000);

starttime = 153000;
endtime = 160000;

tn = TimeNum();

timecond = tn >= starttime AND tn <= endtime;
startday = tn == starttime;

//firstBarOfDay = deFlagFirstBarOfDay( starttime );
//lastBarOfDay = deFlagLastBarOfDay( endtime);
firstBarOfDay = TimeNum() >= starttime ;firstBarOfDay = firstBarOfDay - Ref(firstBarOfDay,-1);
lastBarOfDay = TimeNum() >= endtime;lastBarOfDay = lastBarOfDay - Ref(lastBarOfDay,-1);

myHigh = ValueWhen(timecond, HighestSince(firstBarOfDay,High));
myLow = ValueWhen(timecond, LowestSince(firstBarOfDay,Low));

DH = TimeFrameCompress(myHigh, inDaily, compressLast);
DL = TimeFrameCompress(myLow, inDaily, compressLast);

DH = TimeFrameExpand(Ref(DH,-0),inDaily,expandFirst);
DL = TimeFrameExpand(Ref(DL,-0),inDaily,expandFirst);
DH = IIf(timecond,DH,Null);
DL = IIf(timecond,DL,Null);

SetChartOptions(0, chartShowDates);
Plot(C,"Last=",colorWhite,64);
Plot(DH,"DH",colorBrightGreen,styleDashed | styleThick);
Plot(DL,"DL",colorRed,styleDashed | styleThick);

Plot( timecond, "", colorDarkGrey, styleArea|styleOwnScale,0,1);

Hi

 

Can anyone provide me with a formular that would provide horizontal dotted lines as a marker for the opening 10 minute price range on an intraday chart.    

 

Many thanks

 

Ken
