Place back bet at specified odds only, followed by lay

[Tommassi]

I'm trying to create a automation rule that will follow this sequence;

1. Once a event goes in play, I want place a back bet on the favourite once the price reaches 2.20 as a example.

2. Once the back bet has been is placed, I want to place a lay bet 5 ticks below the back bet price.

3. Once both bets have been matched, I want to Green Up across the field so I win whatever the outcome.

I tried creating a rule, and here is a log of the events;

24/06/2015 14:35:54: Market changed to Salis 24th Jun - 14:40 5f Hcap
24/06/2015 14:41:04: Market has been suspended
24/06/2015 14:41:05: Market is in-play
24/06/2015 14:41:05: Market has been unsuspended
24/06/2015 14:41:06: £ 10.00 Back bet placed on Angelito at 2.2. Fully matched at 2.62. Ref: 10012 ( Offsetting by 5 ticks. )
24/06/2015 14:41:07: £ 10.00 Lay bet placed on Angelito at 2.52. Entirely unmatched when it initially reached the market. Ref: 10013
24/06/2015 14:41:09: Greened up Angelito by Laying 10.56 at 2.48

How can I stop the bet being matched higher in this case 2.62 than what I wanted, even though in this case I made a slight profit

Hi i dont belive you can as when ever a back or lay bet is placed betfair will match it against the best avalible price so in your example because during the 2 sec delay it takes any bet (manual or automated) to hit the market money had appeared on the lay side which was now better than the 2.20 back odds you had asked for so thats what it matched your bet at.
After all if backing why would you not want the highest odds avalible and if laying why not the lowest avalible?

It's fairly easy using spreadsheet automation to trigger at a specific price and offset by 5 ticks. However as an in-play strategy it seems fraught with danger. How many greens would you need to compensate for the occasions where the price does not come in any further?
