Before revision:  We show that by using the level crossing analysis one can forecasts the DAX and oil time series (normalized log-returns) with good precision for the levels in the interval -0.1 < \alpha < 0.1 and -0.35 < \alpha < 0.35, respectively .
After revision:  We show that by using the level crossing analysis one can forecasts the DAX and oil time series (normalized log-returns) with good precision for the levels in the interval -0.5 < \alpha < 0.1 and -0.35 < \alpha < 0.35, respectively .
