Level stake 3 horses

[hedgebets]

Total novice to automation. Have been using a successful strategy manually for 3 years now. I want to try and automate. I need to fire in 3 level stake bets just before the off on 3 different horses in the same race, based on the price of the favourite, the amount of runners in the race and the price of 4th favourite. Would this be possible. Thanks

Do you mean dutch 3 runners so that you have an equal profit on each of your chosen runners?
Or just use levels stakes as in just place 3 bets of the same amount on each of your chosen runners?
