Different data between Oanda fxtrade and Oanda MT4

 

Hi, could you help me

The Oanda fxtrade and the Oanda MT4 are running paralel. I use a PSAR indicator with same parameters (0,1 , 0,2) on fxtrade, and on MT4 too. But the values of the indicators are not same. What would be the cause of the difference?

Thank you for advance
