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 -0.5 < \alpha < 0.5 .
After revision:  We show that by using the level crossing analysis one can forecasts the DAX and oil time series (normalized log-returns ,(which is known as inverse statistics) and provide the distribution of waiting times to observe some level for the increments .
