Seasonality of Greyhound Racing

[CallumPerry]

As per the title, is there?

In the past, I have read/watched Peter discuss this with regard to horse racing and I understand that this will make a difference to long-term success.

With the horses I understand that I should filter my results based on the type of race and thus my returns will vary based on the time of the year, I'd expect somewhat in relation to these levels...

BUT WHAT ABOUT THE DOGS? I ask because I thought I'd cracked it with a new strategy. Over 3 months I had a very nice rising equity curve and then the first half of this month, there was a noticeable dip! Can anybody please shed some light on possible factors? Any possible filter recommendations?

Is there a known seasonality chart other traders use?
Is there anywhere/anyway/anyone that has the number of races run at each track over the course of 12 months (or multiple years)

To illustrate my frustrations...

The numbers are a little small, sorry, but from about market 1-1500 was the first half of June just after the racing has resumed (understandable factor). The rest of June, July and August looks very nice and then the first two weeks of September has resulted in a bit of a dive(???). I have traded around 70% of all races with my filters and each point in the series is a market not just a single selection.

So I feel this is a pretty big sample, 50K+ bets.

The amount of races at each venue doesn't appear to be a factor. Nor the % of money placed on each runner in order of favouritism??

I've had a few PM's already, will try and reply now but if anyone has got some long-term information that may help, I would greatly appreciate it. Keep looking at this from different angles and can't see something which i'm sure is super obvious!

How much volume do the biggest races attract?

I'm aware this is framed quite wide on a single chart but here ^^. Most of the volume is around that £10K-£20K range with the occasional big spike. Doesn't appear to be any noticeable change from this perspective though. I can't really say 'Oh that's where Sept started' just at a glance.

Also, the money matched on each runner in terms of %'s seems consistent. Again, I can't easily state the start of Sept...

The fav consistently sees around 60%+, 2nd fav around 40%+ and with all runners, it seems like I could draw a straight horizontal line to find the average and Sept doesn't deviate too far from this.

Is the general consensus there is no seasonality like horse racing then? And it is just a type of mean reversion myself and other traders who have PM'd me are experiencing? I'm continuing to capture daily data but nervous to still be involved with real money until I find conclusion that makes sense to me.

There's much less seasonality than horses.

[CallumPerry]

Hmmm seems so. I've just broken it up by type of race also. Comparing half of September to the other months in my sample, there were slightly less than average grade A races, a VERY slight increase in Grade D but I think this is skewed by a bump in "HC" and "OR" markets. Conclusion, just unfortunate variance?

My filters are loose enough at the moment that I may be able to smooth out my equity curve with another minimal layer. At the risk of becoming a nuisance, i'll leave this thread here. If anybody has got anything they feel would be useful, my inbox is open! At the very least I hope this thread shows a good way of visualising large samples, might be of use to somebody. I just realised how colourful I have made it with my last few posts

Cheers Callum, not looked at doggos in years. Any volume graphs according to time of day, or over the week by any chance?

I remember quite a few decently liquid races in the evenings.

I haven't done any work in this area so can't specifically tell if there is a pattern. But most sports to exhibit some seasonality.

Perhaps look at the big races and work your way to towards or away from those races.

Also seasonality
may consider bitches
Their season changes also as female
I know thats not the aim but a thought
I have known greyhound owners and some "The Dogs" computer men
say a Bitch in season runs differently as opposed to not
but some were/are "suppressed" when in season which was allowed by the BRGB
Dont know nowadays

I may also add

I used to manually key in greyhound results over 2000 at one track
ie trap, position each bend, weight, dist beat, time ,adj time, going, etc
guess what happened to keyboard whilst typing in trial etc form
split/break 3.22
weight 2.
time 27 etc
28etc
29.
etc
the 2 key wore out

Apart from that,
I learned a lot about
times etc

This may be true
as in horse racing and other sports.

Problem with the dogs is that you reach saturation point quite quickly, if you're trading, so the moon will always be out of reach no matter how many of you are trying.
