hi
here is your trigger
in the constants you can set
bet amount
maximum number of runners
minutes before the off to record the first price
minutes before the off to place the bet
minimum price to take
maximum price to take
maximum price to record the first prices
minimum price drop percent
you need to set mfp to monitor the markets to your set record time plus 1 minute.
the triggers will record any selection with a price of your maximum set price or less.
then at the place bet time, the triggers will choose the selection that has your set drop % and has the maximum price drop %
to improve the trigger it would be better to add an action to record the number of withdrawn runners when the first price is recorded, then in your betting trigger compare the withdrawn runners with the recorded withdrawn runners, if there are more withdrawn runners, this will give false steamers as all prices will have dropped.
please use test mode until you are happy with your settings
