And there's another one. McEvoy 10/3 into 9/4.
I'm getting matched at well under opening show prices at the bookies,surely I should be winning ?

Report Pedro March 6, 2009 4:47 PM GMT
Easy systems rarely work. That is why not everyone is rich. For a start your sample cannot show science (too few races) and secondly you have to work out whether the shorten is rational or irrational. Planned or unplanned (yes the market is manipulated) And that is just the start. You may be taking baby steps toward logic - but there is a long way to go if that is all you have in your staking plan locker.

I had some interesting stats on shortners that took me three months to compile. I accidently chucked them in the bin, I know they were interesting but I cant remember exactly why.
Report TameTheTiger March 6, 2009 4:54 PM GMT
It's not a system,I'm just offering odds at well under the going rate,getting matched on at least one per race,and getting stuffed.
Even though today's sample is small,I've been doing this for a few months and got nowhere.
I've been thinking I'm getting value,but clearly I'm not.
Possible solution is to follow the market i.e back shorteners,lay drifters ?

I've layed Vicario and Seeking Straight in the last.

Look at that ! I can even get the forecast ! :(
Report TameTheTiger March 6, 2009 5:05 PM GMT
Vicario was trading at 6.0 and Seeking Spirit was 8.4 when I made my offers.
I got matched at 4.7 and 6.4 respectively.
It's like that EVERY race.
Can someone (possibly with a degree in maths and probability) please explain to me why I'm not winning over the last month or so ?
Report Robin Ewe March 6, 2009 5:18 PM GMT
The economists will tell you that prices at the close of a market are efficient. In other words the insiders who knew that Vicario and Seeking Spirit had a good chance would back those horses until they no longer represented value. I dont buy that at all though.

If only 10 people were truly in the know and they knew those horses should have been for example 3.0 then it does not mean that is what the price will end up as because they will be able to get all their required stake on at higher prices. Its possible that they knew the 4.7 was still value but they had no money left to back it. And because the rest of the market didnt know the horse should have been 3.0 there was nobody left to force the odds down to a true level.
Report TameTheTiger March 6, 2009 5:26 PM GMT
So despite laying at lower odds,I'm still laying over the odds on some,which is why I'm getting nowhere.
I suppose the answer is to back the shorteners early enough.
Report Thin and Crispy March 6, 2009 5:28 PM GMT
Bingo. Now all you need to work out is which ones will shorten.
Report aprilboy March 6, 2009 5:39 PM GMT
Studied steamers and drifters extensively.

Never found a significant edge,backing or laying.

If you accept that Betfair is a 100% market with no overround,then basically horses are starting at the right prices overall.

Therefore the prices of steamers and drifters were previously too small or large,but end up at roughly the right prices.

All in all it comes back to what is value.
Report Pedro March 6, 2009 5:45 PM GMT
I've just told you - the reason is that you have a simple system and they don't work. Go away and read a book. Better still go away and read a hundred books. Horse racing has maths on several levels - a good player may cross ten strategies over a race to see how many line up! Why would they bother if your "system" gave a happy payout all the time?

If you want to win from starting stalls to line you have to have an independent opinion - odds making - and you have to be right a lot of the time. If you haven't those skills you have NO CHANCE. NON.

What you may be pray to today (and I am guessing) is "over-losing" and there maybe days/times where you are "over-winning". I bet a lot to even these things out. Acknowledging they are there would be a start with some people.
Report TameTheTiger March 6, 2009 6:04 PM GMT
Pedro...I don't expect to win every race or even every day/week.
Your guess is a good one.I've had fantastic winning days and bad losing days.Today isn't the worst day.
i'm not looking for the answer here,just an explanation.Robins post sounds feasible,though I'm still struggling to get my head around that I'm getting matched at crap odds in comparison to the prevailing odds 10 mins before the race,but still can't make much headway.
Like you say,if it was that easy we would all be doing it I suppose.

No need to read any books just watch and learn.

I agree things are there that shouldn't be! Not if racing is totally straight. That why racing won't undergo forensic accountancy. Poker sites are very aware of people shouting "player X" is looking at the other cards and releases the data to prove they are not. Although in one case it was proved that someone was!

Okay, I'll bite...

The stats are for this month to boxing day, taken from the all UK horses that started at an BSP of less than 21.00 and a resulting laying LOSS of 131 points.

If you had only layed the above horses that more than halved from the opening price (less than 50%) you would have LOST 11 points.

If you had only layed horses than shortened to less than 70% (which includes the less than 50%) you would ended with PROFIT of 3 points.

Instead of less than 21.00 BSP you only laid horses less than 6.00 BSP you still would have LOST 13 points.

From the above BSP the less than 50 percenters would have made a laying PROFIT of 4 points while the 70 percenters would have made a PROFIT of 17 points

And you don't need 10 plicks to get off on ;)

Report Beat The OverRound December 29, 2009 2:19 AM GMT
I'll give you a hint.
On the other thread, I lay shorteners that fall well below 10 ticks.

From my stats you cannot predict the shorteners, but you can improve your odds of predicting them.
All shorteners are not value, the biggest percentage shorteners are, if you get in early enough.
Historically backing shorteners from say 9/1 to 7/1 is not profitable, even if you get 9/1.
However, backing a shortener from $2.70 to $2.30 is, but only if you can get on at $2.60 or better.

Look for well fancied shorteners and get on the moment a sniff of a move is presented in the ring.
Some will rebound, some will go back up higher, but enough will plummet to provide a decent return.
Where there is smoke there is fire as a rule, but where there is no smoke, the odds of a fire are massively reduced.

Yarra Valley (Aus) Race 3.

Czarpussy $4.00 $5.50 $3.80 $3.60 - matched @ $5.50 WON
Gavans Gift $2.70 $2.70 $2.40 $2.50 - matched @ $2.75 average odds LOST

Too easy. :D

The signal is the third fluctuation of both horses.
Amazingly, the price went up on the exchange on both horses, while the ring price kept falling.
