Help with Trigger

[Samsam12]

Hi All,

I am looking for the following.

10mins prior to off to monitor the market till 5 mins prior to off. Depending what happenes to certain prices look to back/lay 5 mins prior to off and trade out just before the off. For instance there may be 4 horses im trading on. If say 3 are successfull and 1 isnt then use the profit from the others to back/lay again on unsucessfull trade hoping to green up the whole screen.

I may not have explained it the nest but if you would like me to explain it better then please ask.

Thanks
Sam
