Watched the video on BetangelTV in relation to reversing the book on the ladder, just wanted to know what benefits/advantages this has and what markets this would be used on, or is it simply a case of personal preference?
It is useful because, on the one click trading screen, you might want to lay at the current back price(or vice versa). If you have it not reversed, then you can only back at the current back price or lay at the current lay price.
