Sounds simple enough.
You have a list and basically want to start monitoring the markets 5 minutes before the off.
In the conditions have lay_price less then 15
For fixed liability enter Amount as Liability over lay_price - 1 ... so if the odds drop to say 12 (lay_price) ... then Amount will be 50/(lay_price - 1)
price will be lay_price
This is an easy one .. will do it for you when I get home in about 6 hours time.
Cheers mate. would it be a straight to ask what conditions to put if i also want the bot to spread any loss over all selections in the market should the odds drop to 60% the pre-off lay price?
