Arbitrage Betting

No it's not easy

Far more difficult than it used to be, however opportunities are still plentiful, the skill lies in keeping accounts open and not being too greedy .

Say I can lay a horse for 0.9 and a friend is willing to give me 1.5 for a €100 euro stake. Can someone explain to me how I can guarantee profit here? Help appreciated

Micktheman...........0.9 doesn't exist on here because Betfair always include your 1 unit stake in their prices.

O.9 is expressed as 1.9 on here and 1.5 is represented as 2.5 on Betfair.

I think the calculation you are looking for in order to guarantee a profit is this:

2.5* £100 = £250, this is your potential win, minus your original stake of £100, if you just let the bet go to end and the bet is successful. You of course would lose £100 if the bet lost.

If the bet goes down to 1.9 all you have to do is calculate what 2.5*£100 makes, weve already done this sum it works at £250,

Now take the answer of £250 and divide it by 1.9 the answer comes out at around £131. You now lay the figure of £131 on Betfair, now regardless if the bet wins or loses you guarantee yourself £31, (£31 profit plus your original stake of £100 = £131).

You times your original price by your stake then divide by your new price to get how much profit can make from this example you've given.

Arbitrage hunters should be arrested for impersonating
punters.

^^^^ Yawn there is always one.

one thing to be aware of with arbs are different void rules, eg for withdrawals in tennis.

to be worthwhile, arbs usually need to involve much bigger proportions of your bank than straight punts, and if you don't understand the rules in each market you're betting in, you can suddenly end up having a far bigger straight bet up than you'd ever consider.

as stated above, it can be done. but it's rarely easy money unless you have bots to do the work for you.
