Issue with built-in ATR indicator

I am getting the wrong value when backtesting a bot containing the following code:

The Bot is running on the 1 minute timeframe for the trade pair EURUSD and the backtesting period is between 17/08/2016 and 02/09/2016

 protected override void OnStart()
        {

            MarketSeries m = MarketData.GetSeries(TimeFrame.Hour);
            Print("mTest O = {0}|H {1}|L {2}|C {3} @ {4} - {5} {6}", m.Open.Last(1), m.High.Last(1),m.Low.Last(1),m.Close.Last(1), m.OpenTime.Last(1), m.SymbolCode.ToString(), m.TimeFrame.ToString());
            AverageTrueRange atrHourly = Indicators.AverageTrueRange(MarketData.GetSeries(TimeFrame.Hour), 120, MovingAverageType.VIDYA);
            Print("Current Hrly ATR 120 VIDYA for Time:{0} is {1}", m.OpenTime.Last(1), atrHourly.Result.Last(1));
            double HourlySwingSpace = (atrHourly.Result.Last(1) * SwingSpaceMultiplier);


        }

The Log contains: 

 17/08/2016 00:00:00.000Current Hrly ATR 120 VIDYA for Time:16/08/2016 10:00:00 PM is 0.000480434550042612 

 17/08/2016 00:00:00.000mTest O = 1.1275|H 1.1281|L 1.12749|C 1.1277 @ 16/08/2016 10:00:00 PM - EURUSD Hour 

 17/08/2016 00:00:00.000Backtesting started  

NOTE The value for the Hourly Bar is CORRECT however the value printed for the ATR value that is NOT AS Expected it should be 0.00203.
