Make a 90% back book formula
« on: 18 Jun 2015, 15:21 »
Hi all,

I was just on YouTube watching a video and tried to replicate it using excel but I can't work out the formula needed.

So... you choose one selection that you think might drift and then dutch back every selection at its back price except you edit the potential drifters odds to make a back book of 90% (or whatever you % you choose).

Does anyone know the what formula it might be to work out the odds needed?

Thanks,

Whitey :)
Yeah! :p

Hi tupp,

Yeah sure, here it is: https://www.youtube.com/watch?v=Y4lwfgfaR0I (you can skip to 3 minutes if you want to that explains it in a lot less time!)

Thanks,

I think I've worked it out now, but I need to know how to round up a number to the nearest back price. How do I convert a number (say 9.32) to the next back price (9.4)?
Yeah! :p

I am not sure if I understund you right, but wouldn't it be more simple just to lay your potential drifter?
