Back bet on top 3 ranked horses in win market

Hello, could you please make me a trigger that places a back bet on the top 3 ranked horses at 3 or 4 times the actual sp of the first ranked fave.

I am manually dutching a number of higher ranked horses and would like the back bets on the top 3 to cover the liability in the market should one of the top 3 drift out to get matched at the higher price but then return to win.

Thankyou.

Also could it please include a greenup option for 90% profit.

Hello,

Please find your triggers file attached.
