Try this simple intraday chart indicator. It doesn't have start & end of session time inputs, but perhaps may do the job. [code:1:33324468c5] { http://www.metastocktools.com } { Day's start } nuDay:=DayOfMonth()<>Ref(DayOfMonth(),-1) OR Cum(1)=2; { High/Low of today } Hi:=HighestSince(1,nuDay,H); Lo:=LowestSince(1,nuDay,L); { Plot on intraday chart } Hi;Lo [/code:1:33324468c5] jose '-)

MKZ Try This. The difficulty with the precise start and end times you gave is that they do not indicate what to do in the case of the specified bar not being present. For example, what happens if the first data for 2am arrives at 2.05am. Do you want the previous session to end on the 2.05 bar or the 1.59 bar? The Time1 variable is set to spike true on the first data bar on or after 8pm but before 9pm, so assuming ar least one bar of data arrives before midnight then Time1 will spike true. Testing the value of the current bar being opposite the previous bar is a typical method of finding the leading edge of any signal. The Time2 variable is constructed quite differently, and the reason for that is so that it can identify the trailing edge of the signal (not the leading edge), in this case the last bar BEFORE or ON 2.30am. How you use these various techniques very much depends on how you want to handle potential missing bars and other factors that you may be aware of. There are advantages and disadvantages to almost any MetaStock method, so at the end of the day it's not what I suggest that's important, but what works for you. Try different variations of Time1 and Time2 and somewhere in there is exactly what you're looking for. Time1:=Hour()>=20 AND Alert(Hour()<20,2); Time2:=PeakBars(1,Hour()=2 AND Minute()<=30,1)=0; ldih:=ValueWhen(1,Time2,Ref(HighestSince(1,Time1,H),-1)); {last day intraday high} ldil:=ValueWhen(1,Time2,Ref(LowestSince(1,Time1,L),-1)); {last day intraday low} ldic:=ValueWhen(1,Time2,Ref(C,-0)); {last day intraday close} ldih; ldil; ldic; Roy MetaStock Tips & Tools

So far I find this very usefull: Intraday Dynamic H/L ================== Sth:=Input("Start Hour",0,24,20); Stm:=Input("Start Min",0,60,05); Time1:=Hour()=Sth AND Minute()=Stm; nbars:=BarsSince(Time1); tdih:=HighestSince(1,nbars=0,H); tdil:=LowestSince(1,nbars=0,L); tdih;tdil; ==================
