Price gap between back and lay in percent
« on: 28 Sep 2016, 01:00 »
Hello

I'm trying to create a trigger related to maximal price gap between back and lay price of selection in percents...

Is this condition correct for i.e. max 20% difference betwen back and lay prices?

Selection's Lay Price is equal or less than back_price*1.2

Hi
I think it would be more accurate to convert the decimal odds to binary (implied % chance of winning):
(100/back_price) - (100/lay_price) is equal or less than 20

MarkV, I think the OP's formula is closer to the truth, since if for example back price is 4.0 and lay price is 4.8, then

4.0*1.2 = 4.8, i.e. lay price is 20% greater than the back price.

Whereas if we apply your formula:

100/4.0 - 100/4.8 = 25 - 20.83 = 4.17%
