Maximum excitement on the grand national

THE WORLD’S most famous steeplechase charges into most of our living rooms tomorrow afternoon and Sporting Index have a range of markets to keep you gripped by the action.

A total of 40 horses are set to line up, but how many will finish? Traders are predicting 17-18 will complete the marathon 4m3½ furlong course.

If you think more than 18 will cross the line then you would buy at 18. If there were 22 finishers then buyers would make four times their stake (22-18=4). If only 16 horses finished, then buyers would lose two times their stake (18-16=2).

Shutthefrontdoor is set to go off favourite on the Race Index and Sporting Index also offer a market on the winning distance, quoted at 6.5-7.5 lengths. Fancy a romp? Then you would buy. Think there might be a repeat of Neptune Collonges’ thrilling triumph by a nose in 2012? Then sell.

A 10-length win would make up 10, for example, while for races won by less than half a length: a nose = 0.05, a short-head = 0.1, a head = 0.2 and a neck = 0.3.

First fence casualties are trading at 15-18 (a prediction on the total number of horses (multiplied by 10) that fail to successfully negotiate the first fence).

Losses can exceed your initial deposit. Prices subject to fluctuation.
