Greyhound automation request: lowest price with £100+ matched

[bests3lleruk]

Could somebody help me by creating a Guardian automation `.baf` file for the following rule? I find the automation editor extremely difficult, so I am looking for a completed file rather than instructions on how to construct it. Otherwise is there a way to pay for such a service? And is this possible to create?

What I'm trying to do is catch dogs that get supported as favourite but then drift because something else is supported.

This is what I want for a greyhound market:

1. Monitor the traded-volume ladder before the scheduled start.
2. The first runner to have more than £100 total cumulative traded volume at one exact price should become the permanently selected runner.
3. Once selected, do not change runners, even if another runner later becomes favourite.
4. On that selected runner, identify the lowest odds price at which more than £100 total has been matched at that exact price.
5. This price is the anchor.
6. If more than £100 later becomes matched at a lower exact price, that lower price becomes the new anchor.
7. Then, five seconds (or a different timescale) before the scheduled start, place one fixed-stake Betfair SP back bet on that runner but with an odds condition that it is a certain amount higher than the 'anchor' price. So say 1.5x the anchor price.

Example:

* £100+ matched at 2.14: anchor becomes 2.14.
* £100+ matched at 2.10: anchor becomes 2.10.
* £100+ matched at 2.04: anchor becomes 2.04.
* Minimum BSP is therefore 2.04 × 1.50 = 3.06 rounded upwards to 3.10

By “£100 matched,” I mean the total cumulative traded volume displayed at that individual ladder price.

I would be grateful if someone could attach a working `.baf` file that I can import or let me know A) if this could be constructed and B) how to get someone to construct it.
