What does the colour coding mean? How do I know whether an ARB is open or closed?

• Table - Green text signifies an increase in the price since the close of business at 18:30 UK time the previous working day, 'Red' signifies a decrease and 'White' no change, whist the highlighted data are the margins and represent whether the ARBs are open or closed (simply positive or negative) 

• Pricing Centre - Showing landed price margin; where the margin is positive and green we consider the ARB to be open, conversely when the margin is negative and red we consider the ARB to be closed for the relevant persona

• ARBs Comparison - Showing delivered price, vs listed price basis; the lighter blue is the cheapest landed cost and the darker the more expensive. A mid-blue colour would indicate a small difference between the next cheapest alternative
