Good Morning,
Quite a simple problem but i'm having difficulty implementing this correctly but I am clearly missing something and I am sure it's quite obvious. I am trying to implement back price difference into my betting calculation - If the favourite has moved say -0.5 within 1 minute how can I base my lay bet on this - so lay at current back price less 0.5. It would need to calculate it to the nearest tick. So 5 to 4.5 would be back price-0.5.
Any ideas?
