why different ATR values from different cTRADER Brokers

Hi SpotWare,

why am I getting two different set of ATR Value when using the same code from two different BROKERS (FxPro and RoboForex), using the cTRADER platform.

Have attached the Screen Shot for your review and the Code I am using to access the ATR values.

So any particular reason, why we get two different set of ATR values ???   Also, from morning not able to get the ATR values for EURNZD, CADJPY when using the below code line !!!  is there any problem going on with cTRADER Server.  (*the Chart is loading of these two pairs)

Thank you.
