lay field help please

[andy1967]

Help please. I like to lay the field on horse races at certain odds the night before the next days races. How can i avoid these odds being altered when horses are pulled out before the races start. i.e if i select lay field at 1.12 then this is what i want when the race starts irrespective of how many horses are pulled out, i.e i dont want the reduction factor changing it to 1.01 if for example 4 horses are pulled out.

I'm afraid you cannot choose to ignore the reduction factor. Betfair will apply it if a horse is withdrawn after you have placed the bets. It's the same as if you placed the bets using the Betfair website. There isn't an API function that will allow you to ignore the reduction factor so all API applications will have this limitation.
