Something Ive tried to work out myself but I keep making a mess of it.

Say you have a tennis match :

Player A v Player B

Say that Player A is available at +150.

What should player B be, to make it 100% (ie you could bet both sides and no matter the outcome, finish all-square)

Does anyone know an EASY formula for this to work out the necessary odds and stakes.

Again, try and keep it simple because if its very complicated then I wont understand.

Sorry for such a dumb question but I am trying to get money out of a book but dont want to pay the hefty neteller exchange rate robbery (oh, and plus 3.9% charge!!).

Cheers

Maybe I'm not understanding the question correctly, but the answer seems simple to me: -150. +150 at one book and -150 at the other book leaves you "all square" (maybe I'm not comprehending this term correctly) where all of your funds will now be available at one book.

Owned is correct, anything => -150 will either result in a complete wash or profit. Actually I think it's pretty smart of you to think of this method and I'm not sure why more people don't try this on books that won't payout. It's worth a shot try to "move" the money to another book and as long as they don't close up shop completely even if they win you can try to move it with another bet the next day.

Well, I dont think in US style odds so I always need to 'translate'.

But, if I understand correctly, if

Player A is +150 ... that is 150/100 = 2.5 in decimals ... which means a 100 bet returns 250.

If player B is -150 ... that is 100/150 = 1.66 in decimals which means a 100 bet returns 166.

Is this correct? If so then clearly some stake adjustment needs to be done. Or (as is most probably likely) have I got this all wrong.

Rolemand, yes, sometimes you need to try this to avoid fees ... and neteller have the worst exchange rates (you get shafted both ways) and they charge 3.9% for the pleasure on top.

Whereas, moneybookers are very good rates with no charge. So it can effect my profits quite a lot which bookies I recieve from.

Which book are you trying to get the funds out of?

Bet "X-amount" at one book at 2.50

Bet to win that same "X-amount" at another book at 1.67

i.e.

$1000 to win $1500 (2.500 decimal odds)
$1500 to win $1000 (1.667 decimal odds)

If you can get better odds than 1.67, then you have yourself a scalp.

The math is not hard here Natrass.
Lets say, you want to risk 100 to win 150 with +150/2.5 line.
Then just divide the stake + win with -150/1.66 line and you get the stake you need to risk.

ie (100+150)/1.66 = 150

EDIT: sorry, too slow can I delete my post somehow?

Thanks very much, appreciate the maths lesson there. Seems obvious now of course.

Rolemand, its a US book but Im the paranoid type so I dont want to say until I have shifted this lot (hopefully) ... but the principle is the same for any book in which a currency conversion is needed (GBP to $ or vice-versa). Its not the books fault, could be any, but neteller's in charging so damn much.

This is a good illustration of where American style odds are advantageous over decimal. You can instantly recognize arbs and assess the straddle between lines being compared.
