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;lastBarOfDa y = 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
