If you use Bfexplorer BOT SDK to develop your betfair bots then you can visualize some data on ladders directly, setting different background color in Odds column.
In my video I created two simple bots to show this functionality in bfexplorer.
The first betfair bot loads steamers and drifters for GB and IE horse races from sportinglife web site. The opening horse price/odds is displayed by green background color and the latest one in red background color.
The second betfair bot dynamically recalculates traded volume for back and lay prices, so showing possible price/odds movement.
