Bookmaking On Betfair

[counterfeit]

I've just been going over an old thread on another forum and I came across something that I have not really thought about before, which is laying every horse in every race.

Does anybody have any idea what sort of figures you would need to achieve in order to make a profit, e.g. if you managed to lay everything at SP would you turn a profit? Or, would you have achieve lay prices below SP?

It's very difficult even with a bot, as the % only swings in your favour for less than a second.

Its more or less an efficient book and although there is a small overbet at the top of the book the outsiders mean you will strugggle as you only get an over broke book for maybe 1 second and when you do it is usually hard to get filled.
There is atechnoques you can use to detect a non trending liquid market with and simultaneously put orders to the backside of the book with around a 1.4% margin , i have written a bot in to bet angel through excel to do it for me but you need to be very selective on what races you use. It is not aparticularly viable strategy and there are easier ways to progress SC

I love the little bit at the end - leaves us all dangling.

Thanks for the advice though. I don't think I will bother with it as I am not clever enough to work out how to create a profitable market by myself.

Hi counterfeit,
When making abook and trying to get a margin on it you have to find optimum conditions. The idea is you enter all bets on the back side of the book so you are looking to get offers filled.

the first rule is you want no horse over 30/1 bf price as you have a big worry with withdrawls in this sort of event. You also want a market that has "formed" so look to enter between 5 and 1 minutes to the off. The ideal is a handicap with the fav at least 3.5 and no horse over 30's also try to stick between 6 - 12 runners.
Wait as i say till right near the off and submit all the orders when the percentage is at areasonable level i used 101.4% book as a trigger. You are counting on standard variability for your orders to fill but you will have to calculate and manage the book on horses that drift.
If you have bet angel then it is relatively simple process to create an automated approach with excel
