Dutching for target profit and zero loss on selected faves.

Hello, can you make me a trigger to do the following:

At 1 second in play

Dutch ranked faves 4, 5, & 6 for a target profit of £25

and dutch 2 and 3 ranked faves for zero profit (no or minimal loss)

This for horse races with no more than 8 runners and the fave starting price is between 2.00 and 4.00


Hope you can help.
