Possible by excel and some VBA but I don't think there are any triggers that do what you want, there's a box to set the offset delay in BA but don't think that gets applied to the excel side of things, plus any offset would need you to set some odds so they'd always be above the lay odds.
If you were desperate to bodge a method then I guess you'd have to play around with refresh rates at 30 seconds and use any stop loss triggers to chase the odds to get a match.
