thought that the NonCommercial and Commercial price was getting negative numbers and thats why told about the 0 level, in the picture looking at COTAP seen the center line 0,5 having no 00 like 0.500 and get a bit confused thinking it was 0 (never-mind how i thought it), but in reality is a sequence from 0,2 to 0,8..... been hours in front of charts mind goes BOOM!!!
sorry
