Just playing around with small trades on there, backing and laying same selection
Back £11 at 3.6, profit shows £28.59
Lay £11 at 3.6, liability shows £28.60
Screen now shows -0.01 for that selection if it wins. It was all matched at 3.6 not an average.
Is this an error on there? They should both be £28.60 is the correct answer. Might be remembering why I don't bother too much with them and their interfaces...
