I understand your views but one of the reasons I rarely lay on Betfair is because its so rare to find a value lay. I must admit I haven't looked into these matches but just taking the first one which is laying Middlesboro which at this time you can lay them at 2.78 - about 9/5.
Bets price with the firms is 17/10 and they are betting to around 108%.
So when you say you are laying to a book of 102% are you trading or am I missing something?
Cheers for the reply btw.
np mate I am only laying one side and not trading them, they are just pure lays.
On the exchnages you have to convert your markets to the % the events are traded to on there if you want to get laid. For instance if you bet a 90 minutes football match with three prices to the same % as the fixed odds firms you need to convert them to exchange % of around 101-102 to get 'exchange prices'.
The easiest way to do this is divide your prices by the fixed odds 108 and times it by the exchange % , call it 101.
So in the example you have given at 17/10, this is 37.03% . Divide it by 108 then multiply it by the new % you want to get to, in this example 101%. That gives you 34.64% so around 15/8. So just taking the fixed odds prices and converting it to exchange prices means Boro would be a lay at around 15/8. I happen to think Bioro should be a bigger than 17/10 in a fixed odds book so I would lay them at the 2.78 that is top price on the exchange at the mo.
At the top prices with the books, that game is bet to 102% anyway but the individual layers are betting their 3 prices to much more and thats where your opinion comes into play and you weight your prices accordingly.
Sorry if that is long winded mate and only really covers converting fixed odds to tradable exchange prices.
