This is a basic Guardian automation rule for use on the In-Running Horse Racing markets.
After applying the rule to the days markets, you can quickly choose the runner/s you wish to back in a race from the main guardian page (see bottom image) at any time of the day prior to the race, only if your chosen runner/s are in the top 3 of the betting come post time will a £10 back bet be placed on them.
To use the file just click on the Back Runners if in Top 3 of Betting.Baf attachment link below and this will download it to your computer, then with guardian open on the "Automation" tab click "Import a Rules File" as shown in the image, once imported it will now appear in the drop down box just above, you can now apply it to any markets you have added into guardian.
Once you have it imported into your Guardian the stake size along with any other aspects of this file can be edited very easily by clicking on "Edit Rules File".
With any automation bot always run in practice mode first to ensure everything is working fine, and repeat this each time you make any changes.
