    Time series for forecasting model

    Hallo every body,
    I just have a typical non-stationary time series, in order to have ARIMA forecasting Model I applied the first difference d(1) to this series.
    After the first difference I got the result as following. Is the following series still non-stationary or stationary?
    what do you suggest for order of AR and Ma?
    Thanks in advance
