I use the ATR on the daily bars quote a bit, but am working with a intraday strategy and would like to get the ATR that is the same as the day chart with out actually have to plot the daily bars because this slows MC down a lot. can anyone suggest any pointers in the best way to try to calculate the daily ATR on intraday bars with out doing ATR = Close of data2;

actually i found the function : RS_TrueExtremes which says suppose to do the same thing

RS_TrueExtremes (Function)

but when i load up the example and compare a 9 day ATR on intraday data vs a 9 day ATR on normal data they are very different...

you can read this:
Tutorial 34 - Using ADE (All Data Everywhere) to transfer data between charts
also tutorial n.32.

i think should be helpful for you.
bye

I think Highd(0) - Lowd(0) will give the range for the current day, intra-day data.. (prev close would be Closed(1);
If you want ave true range you would have to allow for the gaps from the prev close, shouldn't be too hard to do..

I posted this code for daily atr for intraday charts somewhere on the Multicharts forum some years ago:

 

Code

Input: Modus ( 1 ), //Modus = 1 : Calculate the ATR including the current date, the ATR drops on the start of the trading //day. Same calculation as on a daily chart using the standard //Average True Range function with "Update on every tick" checked //Modus = 2 : Calculate the ATR over the last ATRLength days excluding today. //Same calculation as on a daily chart using the standard //Average True Range function with "Update on every tick" unchecked ATRLength( 30 ); Variables: x (0), AvDailyAtr (0), Initialized (0); Array : MyATR [50] (0); //Limit to 50 as OHLCPeriodsAgo used by TrueRangeD /HighD... is //limited to arr0[ 4, 50 ]( -1 ) once begin if ATRLength >49 then raiseruntimeerror (" ATRLength needs to be <50 !!!!"); end; If date <> date[1] then begin Initialized = Initialized + 1; If Bartype < 2 and initialized > ATRLength then begin for x = 1 to ATRLength-1 begin MyATR [x] = TrueRangeD ( x); end; end; end; if Modus = (1) then MyATR [0] = TrueRangeD ( 0 ); if Modus = (2) then MyATR [0] = TrueRangeD ( ATRLength ); AvDailyAtr = array_sum ( MyATR ,0,ATRLength-1 )/ATRLength; If initialized > ATRLength then Plot1(AvDailyAtr ,"Daily ATR");
