Bfexplorer's ladder offers 10 columns presenting different type of information. This columns allow you to customize your ladder, hiding or rearranging columns.
For instance you can hide To Back, To Lay columns and instead of them display just one column WoM. Well, yes ladders are here to place bets so then you need to display Back, Lay columns.
Odds column allows visualize odds/price range setting 6 different background colors.
My Indicator column allows to set an indicator value, in range from –1.0 to +1.0, and this column value is accessible through any custom bot.
In my test I created bot which monitors amount of traded volume initiated by backers, and by ladders.
