Backing on the dog with the greatest volume at X minutes before the race


This is yet another Trigger in Action inspired by a BFStats report. The idea came to me a few months ago when I noticed a downtrend in the last traded price of a dog with the greatest matched volume.

I wanted to find out how likely it is that, if a back on a greyhound with the maximum matched volume, its price will steadily decline in the last few minutes before the off, allowing enough margin to green it up to an equal profit.

This testing session had two strategy pivots along the line, so let me give you the breakdown of all three strategies tested. You will find the triggers implementing all three strategies down the next section.

Strategy 1

Back on the dog with the greatest matched volume percentage at 3 minutes before the start of the race. Trade it out with a lay bet at exactly the scheduled start time of the race. 

Strategy 2a

Back on the dog with the greatest matched volume percentage at 2 minutes before the start of the race. Leave the bet there no matter where the price goes.

Strategy 2b

Using Market Locator, filter out markets with a predefined list of distances, as selected using the BFStats report. Back on the dog with the greatest matched volume percentage at 2 minutes before the start of the race. Leave the bet there no matter where the price goes.

Conditions and restrictions common for all three strategies

No loss recovery, no restrictions on the rank or price range of the dog. The minimum and maximum difference between the volume % of the dog with the greatest volume and the dog with the second greatest volume % (the volume gap) are 5% and 80% respectively. That is, if the first dog has 30% of the market money and the second dog has 25%, that market qualifies (30-25 = 15, which falls into the range). However, if the first dog has 90% of the money and the next one has 5%, that market will not qualify as 90-5 > 80.

How to run this trigger package:

1. Download and run the above installation file.

2. It contains three files: the trigger file, the Market Locator search template and the program settings. These files will be copied to corresponding folders on your computer (where other triggers and templates are already stored).

3. Run MarketFeeder Pro and choose the right settings profile from the drop-down list:

Day 4, June 10, 2022

As you can see, the first three days were not looking very promising. There were much more losses than wins, and I lost 20% of my bank, despite liabilities in each race being less than £1 on average. Looking at the logs, I can see that on some occasions the trade-out bets were not placed (the market closed sooner) or they were placed but not matched. That added to the gloomy picture.

At about 2 pm on that day I decided to drop the trade-out bet and move the time of the back bet by 1 minute closer to the start. The reason? The gap between the back and lay prices starts narrowing at about that time, so I was hoping to secure better prices. These are the settings I changed:

mins_before_start 2

I disabled the trade-out trigger, but kept the rest of the triggers unchanged.

Day 6, June 13, 2022

Did you notice a one-day gap here?

On June 11, the triggers stopped in the morning because... the stop-profit trigger has kicked in! I was 50%+ in profit. Remember I restarted the triggers on June 10? My bank balance was £724.38 at that moment, and now it was £1,129.04, so (1129.04 - 724.38)/724.38 = 55.68%.

Unfortunately, I didn't check in to the server up until June 13, and then only late in the evening. For that reason, I reloaded the triggers after 9 pm, and they only managed to place one bet that day.

Total P/L: -11.29
ROI: -100%

Day 7, June 14, 2022

Starting from today, I decided to take the findings from that BFStats report and alter my Market Locator search template, so that it selected markets based on their distance.

In the final setup file, I have deliberately taken out some of the race distances and added others, so that you would still have some incentive to check out the actual report.

The third set of triggers would only back in markets with the following distances:

462m 490m 460m
480m 395m 270m
380m 455m 520m
476m 530m 350m
450m 300m  

I changed the way the bet size was calculated: a percentage of the current balance rather than of the available funds.

Also, to prevent the triggers from stopping once again if they have lost or won 50% of the bank, I pushed those caps up to 150% each:

target_loss 150
target_profit 150

From then on, the triggers were running uninterrupted with no other changes.

Not only di the triggers produce profit compared to the starting bank, the third set of triggers has actually recovered the initial loss of £200+ at the start of this testing session!

However, you can see a significant collapse of the graph line on the last day of testing (down to £890), just before it skyrocketed again to £1,477.91. The collapse was due to a very long streak of losses in Australian markets. What I learned after this testing session has ended, by looking at the statements, is that if I hadn't backed in Australian markets altogether, I would have won £547.73 instead of £477.91. Looks like Australian markets were just standing in my way, although you will get a clearer understanding of the country-by-country picture if you look at the BFStats report.

The triggers available in the setup file can also place LAY bets instead of BACK, just activate the corresponding trigger. Although I did not use any loss recovery in my testing, it is supported by the triggers; you need to set cycle_length to anything > 0 to enable it.

How and where I test the triggers?

I use our BetVPS service to pre-set the triggers and Market Locator and leave it to run on its own until I check on the results at the end of the day.

I occasionally use Time Machine to get a proof of concept or test any tweaks that I want to make to my triggers, on historical markets similar to the ones in which I bet when testing a particular strategy.

I use Test Mode only.

You can generate your own graph and statistics like the ones in these Triggers in Action reports. Read how to do this.
