user49016: 
I can't understand what count means here. I would have assumed that it was the number of orders at that price, but the total column does not seem to reflect this. Can't find any info in the documentation or glossary. Thanks 

user35989: Count:
This is the total number of orders at that level. A count of 1 means that 1 order is at that price point. A count of 6 would mean that there are 6 orders at that price point.

user56028: It's because the Total column is not the cumulate sum of the column Count but of the column Amount. In your example, at the line for price 1612, Total=6.0 and indeed if you do the sum of all amount of the price above 1612 it gives you : 0.3+1.2+1.7+2.8 = 6
