Closing in running unmatched bets at current price

[timjhiggins]

Hi
I am sure there is an easy answer to this but I haven't been able to track one down in the user guide or on the forum.
What I am looking to do in guardian is to close any unmatched bets at the current price once that price is reached. These unmatched bets will have been placed at a higher(back) or lower(lay) price than the current price and this is an exit strategy to get out of the market.
The close trade rule in guardian is based on net stake but of course these unmatched bets have a net stake of zero.

Any help appreciated.

Just to add....
Simply cancelling the bet is not a option in this particular strategy
