Would it be possible to provide the closing price of each future in a forward curve, perhaps in a table under the forward curve chart? If looking at historical forward curves from the past, it would be good if this table also showed the prices corresponding to the day in question.
Perhaps an alternative would be to have a Flash forward curve as you do in Analyser, and see the prices of historical curves as you move the mouse over them.
This would be useful as sometimes it's good to see what parts of the curve were priced at back in time. Downloading data from my quote app means I have to do 1 contract at a time and it's a burden!
