How to - Fill or Kill using greening condition

[jimibt]

All,

Basically, I'm wondering how I would set up a Greening Condition that would allow me to place the greening portions as *fill or kill*. The reason for this is that i'd like to set up and exit a position where the initial lay odds aren't met (eg a B2L). As an example, I may have a back bet in play that i wish to either green or red up but have a rule that only allows one unmatched bet at a time. If the odds slip (up or down), then this unmatched bet sits pending and prevents further (potential) negating transactions being placed.

How would one fill or kill (on a timer) a green/red tx when using automation?? In my *perfect* world, I would like the greening to fill or kill for a specified time, or cancel the transaction, allowing a new atomic fill or kill transaction to supplant the prior call..

Hope this all makes sense.
