Arbing - exploit price discrepancies for a guaranteed profit

Arbitrage betting exploits price discrepancies for a guaranteed profit, whatever the result. You can do this either by backing (laying) all selections in an underround (overround) book, or by backing and laying the same selection with different bookies/exchanges when its Back price is higher than its Lay price. These bets are often known as surebets.

Trading - exploit price movements for a guaranteed profit

Trading is a form of backing and laying that exploits price movements on the exchanges. For example, if you think that a selection's price will rise, you would lay it now and back it later at the higher price to lock in an immediate profit. This is also know as greening up or getting an all-green book, due to the color of your P&L on all selections on Betfair.

Dutching - earn level profits from multiple selections

Dutching is a type of betting that involves spreading your stake over multiple selections so that you would win a level profit if either of them wins. As it is often easier to pick out losers instead of winners, you can also lay dutch selections that you don't fancy. Arb Cruncher also calculates the optimal stakes for each way dutching.

Extract more value using synthetic betting techniques

Instead of just taking the published Draw No Bet price, you can often hedge against the draw more efficiently by placing two separate bets on the Win and the Draw. You can also increase the actual fixed odds of a selection by buying its 25:10 win index (windex) with a spreadbetting company and backing its opponent in the fixed odds market. Arb Cruncher shows you how to place these bets.
