Online Spread Betting

A central feature of financial betting is the fixed risk nature which allows market participants to limit the risk to a known amount. When one opens a bet (long or short) they know beforehand what risk they are taking. What important here is that you can exit your bet at any time before settlement thus you have an option of minimizing the risk even further. The same can be applied to the winning bets (you can collect the win before the settlement time).

Liquidity is always provided and is achieved by the bookmaker acting as a market maker, always being willing to sell bets to a buyer, and in the case it is permitted, to buy bets back from a participant wanting to sell the bet before it expires.
A central feature of financial betting is leverage. The benefit of leverage to the participant is that it allows a greater percentage change in capital than if it were invested directly in the underlying asset. This makes financial betting less capital intensive than trading directly on securities exchanges
