CalculateOnLastBars

Maybe if you can provide a link to where I can find the code for the indicator in the library or the actual code of the indicator then it might be easier to see if your request is possible. It might be possible using MTF and GRAPHONPRICE using a dummy strategy but without the code it is difficult to be certain.

The other option is to work out how many candles there are in a day for the time frame that you use and then only load the indicator for that number of bars so you have the last 24 hours only. As I don’t know the workings of the indicator or what time frame you use it on it is not possible to know if this will actually work or give accurate results.

To be honest with you it isn’t what I would call a slow to draw indicator in the first place! However try this little modification that speeds it up a little:

defparam drawonlastbaronly=true

if day<>day[1] then
startbar=barindex
endif

if date = today[0] then
HIDaily1 = dhigh(0)
LOWDaily1 =dlow(0)
TodayRange=dhigh(0)-dlow(0)


if(Open[0]> 8000 AND  Open[0]< 14000) THEN //DAX
avr = 126
averagerangedown = HIDaily1 - avr
averagerangeup = LOWDaily1 + avr
tickbufferup = +5
tickbufferdown = +5
ELSIF(Open[0]> 18000 AND  Open[0]< 30000) THEN //YM Wall Street
avr = 300
averagerangedown = HIDaily1 - avr
averagerangeup = LOWDaily1 + avr
tickbufferup = +6
tickbufferdown = +6
ELSIF(Open[0]> 1000 AND  Open[0]< 4000) THEN //SP500
avr = 30
averagerangedown = HIDaily1 - avr
averagerangeup = LOWDaily1 + avr
tickbufferup = +2
tickbufferdown = +2
ELSIF(Open[0]> 5000 AND  Open[0]< 10000) THEN //nasdaq
avr = 103
averagerangedown = HIDaily1 - avr
averagerangeup = LOWDaily1 + avr
tickbufferup = +2
tickbufferdown = +2
ELSE
result = result
