hi
here is a trigger got you to try.
in the constants you can set
bet amount
price increase %
minutes before the start to check the prices
maximum liability (the actual liabilty could be slightly more or less due to the bets been placed)
the triggers will check to see if any selections price increases by your set amount, then a back bet will be placed and lay bets to any other selection, the triggers will then repeat the process.
please use test mode until you are happy with your settings
