Do Tipsters' Selections Lead to Profits?
 
Has anyone looked at Tipster's selections as a way of working out a price to bet to collect a predetermined amount?

I have a "stable" of 35 Tipsters which I use to determine horses to consider.

Has anyone else tried this approach?

OK

Thanks for the reply Partypooper (Ha Ha), great to see you are still going strong, especially in these difficult times.

One thing I have noticed with using the Tipster's selections is how the Jockey plays such a significant part when backing the selection. I have found that jockeys you would expect to win fall short time and time again. Others you would not expect, as they are not in the top Jockey group, continually deliver victories.

I am talking about Melbourne races, but I am looking at Sydney races as well (but very early stages)

Do you use the Retirement Staking Plan? (I may be wrong but I think I sent you a copy of the spreadsheet a few of years ago).

G'Day TRY,

Yes still here, NO MORTGAGE, but no private jet YET ! with the tipsters thing, you know they do pretty good all things considering. I've found that just deleting ALL odds on and ALL HEAVY tracks improves that bottom line.

You can can get many breaking even Or a bit better. You can improve that into profit using BFSP, or better still using BET BOOSTS etc, but best of all is using BET RETURNS. Question there of course is how long will you get away with THAT!? hahahah!

I remember a thread on here once that said something like look for the odd man out or back the tipsters second pick if you had 10 or more.

Thanks for the replies guys. It seems there is very little discussion going on now-a-days which is more the pity.

One aspect I have looked at is

1. Only considering the first 5 races on Saturday Melbourne meetings.
2. In Race 1 back Tipster's top selection for 1 unit a win
3. If a winner, pull up stumps, job done
4. If a loser, in Race 2 back Tipster's top selection for 2 units a win
5. If a winner, pull up stumps, job done
6. If a loser, In Race 3 back Tipster's top selection for 3 units a win
7. If a winner, pull up stumps, job done
8. Continue through Race 4 and 5 stopping at a winner or betting 4 units or 5 units.
9. Maximum loss is 15 units per meeting

Most Tipsters have a positive POT% after upto 80 meetings (some Tipsters have less meetings due to holidays etc, and me finding newer Tipsters to include).

Although not actual Tipsters, among the worst performers are horses with highest win%, highest place % and horses with highest average prize money. LOT are -27.4%, -35.0% & -40.4% respectively. I find this quite interesting as Win%, Place% and Average Prize Money are areas often used to zero in on horse selections.

Prepost Favourite currently has a 12.9% POT (62.9 unit profit on 487 unit turnover) which may substantiate the theory more favourites win on earlier races.

I appreciate any comments.

One of the guys I know uses tipsters but he uses a Baysian approach to it. He says it works well.

Here is a rough guide to it: https://www.sportstradingnetwork.co...sters-final.pdf

Another interesting read: https://www.pinnacle.com/en/betting...NL2722PUAZM4Q8Q

Hope that helps.

This approach can work well, using the tipsters.

RULES
Target tipsters 2nd & 3rd sel (Ignore Top sel)

Selection is the horse that is $3.20+ in the Fixed price TAB/Bookies price or , at 30 secs until jump time.

If still left with 2 horses . Take the shorter price of the $3.20 runners.

Target first 5 races for each venue.
It usually hits one winner in first 5 races.

Stop at that venue after each win.
Do the same for each venue. First 5 races only.

Betting $2,3,4,5,6 = 20
For 5 bets only , then start again.

The plan hits many good prices, especially where there is an odds on runner in the race.

Try it out.

Cheers.

Bhagwan 30th August 2021 10:30 PM

I forgot to add ,

Have 12 banks of 20 units = 240

This allows for 60 outs.

Cheers

Tipsters have great runs and very poor runs, Dean Lester used to be great, but he's been struggling very much lately. There was an article where if the CURRENT tipsters are in form, and they all agree on a top selection, then it is a good bet and amazingly they're not all favourites.

Tipsters
 
Tipsters are a bit like Ratings. They are someone's Opinion. I know of one tipster in NSW, that tips, the first 4 in the early market every day and get's paid for it. If the fav has a good day, he has a good day. You are right, Tipsters are hot and cold, just like horses, how does a horse, beaten 32lens in 3 starts, win the next start at 100/1?

Ratings are the same, someone's Opinion. If you take a set of rules and give each rule a value, you come up with the best horse, 100 rated. If it is the best horse, it will be the fav. So why not just give the fav 100 points, that's my opinion! Saves a lot of work.

As we all know, backing fav's will send you broke. Bookies and Corporations have already drop the prices on these horses, way below the chance factor.

So how do we win, well it is your own opinion in the end. The algorithm you come up with, is a start. Allocating point to varies Rules, to start your algorithm, could look like this, Market 50 points, 50 to the fav, then 40,30, 20,10 and 5 for the rest. Win in this Class, 30, Place in this Class, 15 points.
And we continue with a few other Rules for Points. Now we have our Opinion or Ratings.

That's fine BUT! There is not one Computerized Algorithm that will stand the test of time, In My Opinion. I have been doing ratings for 25 years, millions of test and they all fail the test of time, they go great for a Month or two, then 0/7 the next day, 1/8 the day after, WHY! Horses are no machines, they can be moody, for bid, the Jockey has a bad day, he let's the horse go back to last and wait's for gaps on the rail, that never appear and so on.

I do my for analysis with all these area's in mind. Look at the Jockey, is he hot or not? Is the horse is going up in distance and down in class? Blinkers First Time? These and other form factor's I use to determine my Opinion and value I'm getting for that Opinion, makes up my mind, whether to wager or not. Not Tipsters.

Chrome Prince 12th April 2022 03:00 PM

I am currently undertaking a linear regression model, but need to add some factors, most importantly up or down in class or same class. With 23 and a bit years of data, I think I can definitely create something with a long term profit for backing or loss for laying. Blinkers first time, gelded etc is not something I have a record of, but still, I think I can come up with something using pure mathematics. In form jockeys and trainers win, but they also lose and that's where I think the profit is. For Example September Run in the William Reid was way over the odds at $17.00, she'd finished 3rd in the Group 1 Newmarket at Flemington beaten only 0.6 lengths and was going over the same distance at the Valley from a Good4 to a Good3.

Tipsters
 
I have no doubt you could CP, You would have to pick your races though.

No Restricted races, 4 year old maiden races, Class 1 or BM races <58.

Your data would show that, as would 4 or more first up runners in the race, they are hard races to gauge their fitness.

That's why I say, Tipsters are a no go. They are trying to select the winner in every race. Computerized Algorithms are the same. AAP, Sky, Racenet, the list goes on. Computerized Algorithms are a one touch button for ease of application. Someone in the office, comes up with these Algorithms, then the youngest staff member, presses the button, then format's the selection results.

There is no way you can select enough winners, in all races to be profitable, in an algorithm.

Yes CP, laying those fav in the poor races and betting on the good races, you could make a profit long term, I agree but if we are talking about Tipsters, they mostly publish the winning hopes in every race.

UselessBettor 16th April 2022 11:55 AM

I cant be too hard on tipsters as they don't know what the odds will be at race time so I they can only tip what is going to be the most likely winner and that is not surprisingly the favourite or second favourite.

I wouldn't use them in a systematic method though as they are not a controllable variable. You don't know when they are really putting in the work vs just going through the motions (or copying from somewhere else).

A rating is consistent though (providing you can talk to the person who creates it and they let you know when and if it changes). But there are still times that these can change and you are not told but its less changes then a tipsters picks.

Unstable 18th April 2022 10:33 AM

And that's fair enough too UselessBetter. Tipsters usually do their tipping day's before the race, in some cases. The changing track conditions, can catch them out too.

Yes, they mostly tip fav's and that makes sense, as that would be the horse, with the best form. We know, that fav's win on average, around 34%. So, for this example, we are going to look for an average of 3 winners on a 8 race meeting. Let's call this system, "True Fav's". Say we take the Tipsters top 3 selections, we then do an analysis on them 3 only.

We are looking for a Top Jockey, a fit horse in form and a horse that has come in for good support, $4.00 into $2.80 for example. No odds on. Now we have a "True Fav".

A horse supported in the market, good form and a leading Jockey on board.
Hopefully, we get 3 bets at that meeting, all over $2.00, if not, the next meeting we may get 4 Selections?

Yes, this example is, at the pointy end of the market, but it can be a way of reducing the work load by, letting the Tipster and Market find the Qualifiers, then, you decide the best Jockey out of those Qualifiers and look at some form to confirm it's Selection. Weeding out the rubbish can and will increase your SR, to a level that makes this type of system profitable.

Another away of using Tipsters??

Python
 
Shaun, is it possible to scrape data from Sky's new tipsters site, in Python?

Or does anyone know if it can be done in Python?

I have a couple of theories I'm testing, but it is very time consuming. Sat, 15 meetings, takes forever manually.

Any help would be appreciated.

This will get you the meetings, just adjust date
https://api.beta.tab.com.au/v1/tab-...urisdiction=VIC

Copy the whole page and paste in to this website to make it easier to read.
https://jsonformatter.curiousconcept.com/

On the meetings page you will find other links like.

https://api.beta.tab.com.au/v1/tab-...urisdiction=VIC

And on that page you will find links to form.

https://api.beta.tab.com.au/v1/tab-...urisdiction=VIC

You just need to play with the dates, all the sky info is there like what they show in the panels, not sure about tipsters, i haven't looked.
