How to get the correct ATR to display

[rick0735]

My objective is to print a line of text at the bottom of a chart window that contains the daily ATR for the one-minute series I am charting. I can get through most of the gyrations okay (I think) except I seem to be pulling the wrong value. The instrument on the 1-minute chart is MES. In the OnStateChange() event, if (State == State.Configure) I
AddDataSeries(BarsPeriodType.Day, 1);
Then, when (State == State.DataLoaded), I print out the following values for BarsArray[0] and BarsArray[1]:
Instrument.FullName, Instrument.MasterInstrument.Name, Instrument.MasterInstrument.TradingHours.Name, and TradingHours.Name.
The four values are identical for both BarsArray members, and I assume this is because the call to AddDataSeries uses the BarsArray[0] information as a starting point when creating [1].

Here's the problem: When I display the data box and hover over the next-to-last bar on the daily chart for the same instrument, the value displayed in the data box for ATR(Daily,14) is 93.23; but when I extract
double atr = ATR(BarsArray[1], 14)[1];
on my minute chart and print the result to the output window, I get 74.5 (I do a little massaging to get the value of the next-highest tick to display) - so nearly a 20 point difference.
FWIW, when I do the same exercise with the one minute chart and data box, the numbers are acceptably close (though I kind of expect them to be identical; still, I'm not gonna quibble over a few thousandths of a cent).
Any suggestions would be appreciated, thanks. As an alternative to making the numbers agree, if anybody knows which one is correct, please point that out and explain. I assume the value on the daily chart as calculated by NT is the answer, but I want to derive that programmatically for myself. I suppose I could dive into the NT indicator code...

Hello rick0735,

Is the ATR added directly to the same 1 minute chart the script printing the value is added to?

Have you manually added a 1 day series to the chart and used that as the input series for the atr?
(If not, may I confirm the ATR added to the chart is using the 1 minute series as the input series?)

Sorry, I guess my attempt to keep the question compact only obfuscated things. Thanks for looking at thhis.
As I was preparing a more code-like readable response, I noticed the following line in the code I found somewhere in the NinjaScript help files This happens in StateChange = State.Configure:

// the host must also call the exact same AddDataSeries() call in it's code as well
AddDataSeries(BarsPeriodType.Day, 1);

So I added the 1-Day series to the main chart as well, in a new panel (which I minimized). All values line up properly now.

Funny how things improve when you're forced to explain the problem more clearly. You can close this.. Thanks.
