hi
here is your trigger , in the constants you can set.
Bet amount
Minimum price
Maximum price
Minimum number of runners
Minimum to be placed
Minutes before the start time to place bet
I have used the statement for the last bet amount because the statement is updated after every race so if mfp crashes the trigger will still bet the correct amount ( this will not work in the time machine as it resets every time the markets are restarted ).
please use test mode until you are happy with your settings
