What is arbing?
Arbing is backing a bet at a bookmaker and laying the same bet at an exchange, at prices that lock in a profit. It is also the quickest way to get your bookmaker account limited.
How arbing works
An arb needs two prices for the same bet: the bookmaker's back price and the betting exchange's lay price. Laying is betting that the horse will not win.
When the bookmaker's price is bigger than the lay price, the two stakes can be set so that the profit is the same whether the horse wins or loses.
A horse is 6.00 at the bookmaker and 5.00 to lay at the exchange. £10 backed at 6.00 and £12 laid at 5.00 make £2 whether it wins or loses, before exchange commission.
Why it gets your account limited
An arber only bets when a bookmaker's price is out of line with the exchange. Bookmakers look for that pattern and restrict the accounts that show it: stakes limited to a small amount, promotions withdrawn, or the account closed. This is called a gubbing.
Value without arbing
EWEdge picks are each-way value bets you back at the bookmaker without laying off. This is called each-way no lay (EWNL).
Shrewd mode makes sure that neither the win nor the implied place price is an arb, to look less like sharp betting. This helps your bookmaker accounts stay open for longer.
