383:(colloquially "arbers") attempt to simultaneously bet on all possible outcomes to make a guaranteed profit. A trader operates similarly to an arbitrageur but is willing to take on extra risk and bet on events where no immediate profit is possible. A trader hopes to make a profit by closing out the bet at a later stage at more favorable odds. Closing out a bet for profit involves collecting more money by laying than is paid out when the outcome is backed back. If the event does not occur then no money is lost, alternatively if a trader is able to lay a higher stake at shorter odds than his back stake then he can theoretically guarantee the same amount of profit regardless of the outcome. On the other hand, if the odds move against the trader he might elect to close out the bet so as to minimise his loss. Trading can be done either before the start of an event or while the event is in progress if in-play betting is offered. Compared to trading before the event commences, trading in-play usually involves both greater risk and also the potential to make more money.

and under 100% for the lay selections. This ensures that simultaneously backing or laying all selections in a market will not normally guarantee a profit. Occasionally though (especially in circumstances where odds are prone to change rapidly) exceptions will arise where offers to back or lay all selections will be made that if simultaneously and cumulatively accepted at exactly the right stakes would permit an arbitrageur to guarantee a profit. However, such phenomena tend to correct themselves very quickly and exchanges generally try to dissuade customers from attempting to take advantage of such circumstances.

and usually involve relatively small stakes. Fortunately for traders, almost all betting exchanges charge commission on net winnings only and charge no commission at all in the event of a net loss. This suits the trader's high turnover, low profit strategy provided he bets exclusively with a single exchange.
398:
Furthermore, for a trader or arbitrageur to combine different exchanges and/or bookmakers for a profit requires a substantial price differential if a profit is in fact to be made once the exchange's commission is taken into account. Even between exchanges, such large price differences are rare, brief

Traders can make money by betting exclusively with betting exchanges or bookmakers, or by combining the two. The trader could lay at a low amount on a betting exchange and then back at a higher price with a bookie or another exchange. This must be done simultaneously to guarantee a profit or else the

For example, if someone thinks that Team A will win the competition, they may support that choice. The bookmaker offering this bet to the player will choose this option. Both sides will agree on the sponsor's bet and odds. If the team loses, the layer/bookmaker retains the patron's bet. If the team

interests. Exchanges also assert they are well aware of who their customers are and keep a complete record of all betting activity in case of enquiries, whereas high-street bookies take anonymous cash bets. Furthermore, customers can monitor the odds on the exchanges' user-friendly platforms
402:
Unless a trader is willing to accept the risks inherent with in-play trading, the profit or loss for a trader will typically be no more than 10% of the total amount of his combined back and lay stakes in any particular market, so to make meaningful amounts of money a trader needs to commit a

but the exchanges act in the same manner as traditional bookmakers in doing so (i.e. they themselves and not a customer act as the layer of such bets). Exchanges also tend to restrict the odds that can be offered to between 1.01 (1 to 100) and 1000 (999 to 1).

In spite of these advantages, exchanges currently have some limitations. Because exchanges seek to concentrate their liquidity in as few markets as possible, they are not currently suited to unrestricted multiple parlay betting. Betfair does offer
