Making an Exchange Lay Bet and calculating your liability to use in your “Back to Lay” Trade

Making an exchange lay bet is not as simple as calculating your porential profit in a normal back bet. With a back bet you simply multiply your stake with the odds, subtract your stake and hey presto the figure left is your potential profit.
The lay bet calculation is a little bit more involved and has nothing to do with the picture above (That is just the Kelly Criteria equation for anyone who wants to look it up)
To calculate your liability (How much you would lose if the bet “won” remember with a lay bet you are betting your selection will lose) the following equation is used

Liability = (Backers stake x (Lay odds – 1)

For instance in the 15:05 at Ascot yesterday (1st Oct 2021) Chalk Stream was 3.6 to lay. You don’t think as others do and think it has no chance and want to win a tenner if it loses so you need to know how much you would lose if it wins

Liability = (£10.00 x (3.6 – 1) = 10 x 2.6 = £26.00

To win your £10.00 you stand to lose £26.00 if Chalk Stream wins.
This is the basic calculation and you would need to take off your commission from any winnings.
For instance if your Betfair commission rate is 5% then your £10.00 profit would be subject to a 5% reduction equalling 50p leaving you with a total profit of £9.50 if Chalk Stream loses and a £26.00 loss if it wins.

To make this lay bet you would need at least £26.00 in your betfair account. Things get really interesting when you need to calculate your liability when making Back to lay bets.
Lets take todays first Back to Lay selection on the In-Running Trading Tool feature.

Highfield Princess is running in the 13:30 at Ascot total (2nd Oct 2021) and is currently at 4.3 to win so we back her at that price for £10.00 – a simple no-nonsense back bet, we lose a tenner if it loses and win £33.00 if it wins.
I personally lay my “back to lay” selections at a set 15 tick “drop” from whatever price I backed. For this I use my own “Betfair tick counter” in the form of an excel spreadsheet which I made myself and is available free to download at the end of this page.
A 15 tick drop from 4.3 is 3.4 so now I need to calculate an equal profit liability lay order at odds of 3.4 so that if the horse trades in-play at odds of 3.4 I will win whatever the outcome.

To do this I simply use one of the many “Matched Bet” Calculators on the web, my favourite being Odds monkeys free bet calculator as shown below

Click the pic to go to the Oddsmonkey website

As you can see from the screen shot above if the odds in-play reach our 15 tick drop we would win at least £1.72 even if the horse loses.
As promised above my betfair tick counter is available for free download by clicking the link below. It will calculate odds required for a 20 and 30 tick drop as well as my default 15 tick drop by simply inserting the back odds into the relevant cell

The example shown on this page wasn’t plucked out of thin air. I subscibe to a website called In-Running Trading Tool which provides daily data on various trading strategies ranging from Back to Lay trading to “DOBBING” or Double or Bust trading on every horse running that day. Highland Princess is just one of several selections highlighted by the site for todays racing. I am currently on a 5 bet winning streak and playing with free money after taking my original stake out after the 3rd bet. These trades were as follows
28th Sept – 13:35 Ayr – Le Cheval Rapide – Trade won Horse lost
29th Sept – 13:40 Bangor-on-Dee – Robin Des Theatre – Trade won Horse lost
30th Sept – 14:00 Warwick – Friend or Foe – Trade won Horse lost
01st Oct – 13:35 Fontwell – Pasvolsky – Trade won Horse lost
01st Oct – 14:45 Fontwell – Keepyourdreamsbig – Trade won Horse lost
A full breakdown of these backed and liad bets can be seen from my downloaded excel file below
I used the minimum stake of £2.00 for the initial bet adding my profit to this each time until I had won enough to bet with just profits.

Keepyourdreamsbig

Back to Fontwell again today for bet No 2 and I have discarded my original stake of £2.00 placing the total profit so far of £3.15 at odds of 3.05. This will make my Lay order of a 15 tick drop at 2.72 for a stake of £3.56

Fridays “Back to Lay” Selection for the second race at Fontwell

Pasvolsky

End of the working week for me and an empty house means a fun filled afternoon with the horses. First on my list today is Pasvolsky in the 13:35 at Fontwell. This is a slightly longer race today that he is used to running but watching previous races he has been a front runner. I have backed him at 5.3 with, like yesterday, original stake plus profits which amount’s to £3.79 a 15 tick drop lay order has been made for £5.18 at odds of 3.9.
With just an hour to go the odds have come into 4.8 giving me a 5 tick head start.
With the exception of his last run at Sandown on 24 April with Sam Twiston-Davies in the saddle Pasvolsky has Won or Placed under Tom Cannon on good or good to soft going over hurdles and won one and placed in his other NHF race.
Now at 4.7 (12:50pm) things could go well in this race.
The “In-Running Trading Tool” form table is below and clearly shows his front running form and particular notice should be taken of his in-play exchange prices

His short in run returns are in red figures and this marrys with his fading off in the races in which he placed or lost.

Todays “Back to Lay” Bet 1 Thursday

Friend or Foe

The first Back to Lay selection today is Friend or Foe running in the 14:00 at Warwick. I have backed it at for £3.38 (my origional stake plus profit from yesterday) at odds of 2.92 as the odds were falling but it seems I was a bit premature as the market has drifted out a bit to 3.05 as I write this. My lay order of £3.80 at a 15 tick drop to 2.62 probably wont get matched before the off but I am hopeful that the traders will help me out as the race gets under way. Having just watched his debut into chase racing on the 1st May this year , he was content to sit at second until about the 3rd from home where Briony Frost let him have his head and motored to victory, winning by nearly 5 lengths. His last outing as a hurdler was on heavy ground at Wincanton and he didn’t fare too well finishing 4th out of 5 finishers in the Betway Kingwell Hurdle on the 20th February 70 days previous . Making heavy work out of the heavy going it is plain that the going today at Warwick should suit him as the distance of 2m and good going seem to agree with him. Harry Cobden rides him today instead of Briony Frost but has 3 wins and 2 places from 6 rides. His other ride on Friend or Foe was on the 23 march 2019 where he came 10th over a bigger distance of 2m3f. At the 2 mile point he was just disputing the lead but faded badly after 2nd from home fortifying the desision to run him at 2m or there about to optimise his talent.
With 1 hour to go before the off the market on Friend or Foe is static at about 3.05-3.10

Todays Best Back to Lay bet of the Day

Not much time to get onto this as todays Back to Lay bet runs at 13:40 at Bangor on Dee.
Robin Des Theatre has a 25% win rate from 4 races on at 1m7f and 3 at 2m. This horse likes to lead from the front and has an average betfair tick drop of 106. Its highest BSP was 11.5 and dropped a total of 22 ticks to a in-play low of 6.2. This was its last time out at Newcastle over 2 miles on 20 march this year. Todays jockey, Brendan Powell rode it to victory in another Newcastle hurdle over 2 miles 21 days previous to that. Todays race is a 2m 1f Handicap Chase, a first for this horse but the market seems confident in the final 2 hours to post time as I backed it at odds of 16.00 and I am looking for a 15 tick drop to 9.4 to lay. With just 50 minutes to post time the market has shortened to 11.5.

The screenshot above shows the steady shift downwards and how close to my Lay order the odds got as it dipped to below 10.0 about an hour before the off.

DOB of the Day (Sunday 12 Sept)

Welcome to todays DOB of the Day Post where, unfortunately there is only 1 selection that meets the criteria laid down for this. La Petite Coco is running in the 14:20 at the Curragh this afternoon and whilst it would be the Ideal contender for today It has 2 horses in front of it in the betting who are both front runners and the markets probably wouldnt be able to sustain 3 selections shortening so much.
Timeform pace hints favour Love and Thundering Nights the two horses in question. I am going to give this one a miss today which after my luck yesterday with the Betfair “Outage” the damned thing will probably go on to win 🙄
There are some higher priced horses in other races which I am going to set betangel in practice mode to automate the process

I have created this automation rule to the exact instructions of the betangel maestro, Peter Webb, and I am running BetAngel in practice mode.

The selections I have loaded into betangel are the top DOB possibilities as sorted by the In-Running Trading Tool

Click to enlarge in another tab

If you enlarge the sceenshot above you will see why onlt La Petite Coco was the only one to meet MY criteria, Heavenly Power, Point Lonsdale, and Barrington Court are out side of the odds scope While Fast Response and Turbulance have a “red” short in running total.
This is a “blind” trial as I have simply loaded the selections into betangel with instructions to back the horse 5 seconds before post time at current odds and put a corresponding DOB lay order in the market with instructions to keep when event goes in-play.
I have also instructed BetAngel to record the lowest in-play traded price for the selection.
I have done no other research apart from the initial findings as outlined about La Petite Coco.

Todays DOB of the Day Friday 10 Sept

Todays DOB of the Day is Makinitup running at Sandown this afternoon in the 15:35.
Making the criteria easily this 3 yr old filly has raced 3 times winning twice. This is the first Handicap she has raced in but it seems that she is in the very capable hands of Cameron Noble as Timeform have posted this in their “Specific Pace Notes” –
“Hold-up horses normally aren’t favoured at this trip here and the pace forecast suggests MAKINITUP (IRE) should still be better placed than AREEHAA (IRE) to take advantage.”
A slight negative to this is that she is yet to run over good ground competitively and the market should be watched nearer post time to see where the money is going.
I however have thrown caution to the wind and Backed her at odds of 4.3 and placed my lay order into the market at odds of 2.13

Click to open in a new tab

As you can see her forecast odds are 3.25 so I am hoping that the market will come in closer to post time shortening the gap to my lay order. If you look closely at the image above you can see that as the pace note say Areehaa might well run from the front but is perhaps unable to sustain this as her DOB rate is just 50% and in actual fact she has drifted slightly in the market in response to money going onto Pearl bay who has been backed into 6.2 from about 6.8 a few minutes ago.
There is now just 40 minutes to post time and I apologise for the lateness of the post but I had a Puncture last Night putting me about 3 hours behind – Fridays!!!

DOB of the Day – Thursday (9 sept)

Yesterday was another successful trade with Anmaat winning makes that £10.00 profit less a bit of commission. Today there were 2 possibles but Kawida in the 14:40 at Doncaster is now a non runner, leaving Free Wind in the race after at 15:15
To remind you of the criteria

  • DOB rate of over 85% average for all races
  • Short in running figure zero or greater
  • A “DOB return” of over £25.00
  • Forecast odds between 3.0 and 20
  • A “Runstyle” of 1 or 2

Todays selection meets all of these conditions. Early this morning I backed it on the exchange at odds of 3.85 and subsequently put my lay bet order in as soon as the back bet was matched. (I should point out at this stage that there was a significant gap between the back odds and the lay odds (3.4 to back and 3.9 to lay) so I simply asked for a £5.00 back bet at 3.85 this was matched quite quickly so it is well worth NOT taking the back odds as is, and trying for a bit more. By doing this I have gained 9 ticks, not much I know but every little helps.
At some point in the morning Glenartny was withdrawn at odds of about 15.00 so the rule 4 was invoked and now my back odds are 3.6 and Betfair has automatically adjusted my lay bet so no harm done. All that been said there are a couple of points to fortify the decision to Dob this horse.
In its previous race (which is not shown in the In-Running Trading Tool) Free Wind was ridden by Frankie Dettori in Deauville to victory over a mile and a half in August beating the favourite by 1 and a half lengths showing that there is a horse/jockey connection to todays race as Dettori hadn’t ridden Free Wind before.

DOB of The Day Wednesday

After yesterday’s success with Past Time, I am £5.00 in profit after backing her at 4.4 and she traded at 1.77, 33 ticks below the required 2.2, we move onto today’s DOB of the Day.
Running at Doncaster in the 16:30, Anmaat has forecast odds of 4.00 and a DOB percentage of 100%. £49.00 reflects the 5/5 times he has run and “DOBBED”
With an average racestyle of 1 he prefers to lead or just tuck in behind the leader and after looking at his previous runs seems to make his move 2f out and giving all in the final furlong. One concern would have been if the going was good to soft as a previous race was lost seemingly due to the ground not being exactly to his liking and tiring him 100 yds from the finish allowing Encourage to win by 3/4 length. that being said an in play low price of 1.33 suggests the work was done inside the 2nd furlong from home.
I actually backed him at 5 o’clock this morning at odds of 5.7 so my exit price is 2.86
This price is still available
There is more information today and I am grateful for the additional resources provided by #caanberry and #timeform which is ever-present on one or more of my computer screens
There is one other possible DOB candidate but it fails on the short in- running condition. This is Al Simmo in the race after Anmaar’s at 5 o’clock full details and a free 7 day trial of the In-Running Trading Tool can be had by clicking the link below

Update 100% win rate

Yesterdays Blog post “Using the In-Running Trading Tool with the Racing Press Top Tipped Horses to determine “Back to Lay” selections” gave, in some detail the workings behind narrowing down the back to lay dilemma.
Fridays selections produced a 100% success rate. So how did yesterdays selections fair
Just to remind you these were
14:00 Ascot; Alotaibi
14:20 Haydock; Valley Forge
18:30 Wolverhampton; Loves Me Likearock

Alotaibi was forecast at an S.P. of 1.33 and you would be excused from thinking that with 10 tips from the National Racing Press “Experts” that this is surely one of those banker moments – Alas it was not to be as Wanees came home in front! However Alotaibi did have a B.S.P. of 1.85 which was 13 ticks more than the industry S.P. and reached an in-play Low of 1.4! This was in fact a 45 tick drop – more than enough to meet our requirements of 1.7 for 15 ticks and a small profit
Valley Forge with 11 tips and a NAP pushing it along and an attractive forecast S.P. of 3.00 (2/1) many a punter would think that it is “money back time” This was not to be unfortunately as Valley Forge managed just 3rd out of a field of 6. But as it turned out all was not lost as the B.S.P. was 2.51 and his in-play low dipped to 2.00 giving a tick drop of 25. This gave an in running profit of 12.8%
With 2 out of 2 losers as far as the straight punters were concerned, I on the other hand have an overall profit of 10% on my stakes.
The evening meeting at Wolverhampton and my last selection in this system was most tipped horse with 12 tips, Loves Me Likearock. Winning by just half a length very nearly made it 3 disasters for the favourite backers. Going off at 2.07 at the Betfair exchange traded to the lowest possible at 1.01 and another win for the system and finishing up 10% up on my stakes

There are just 2 selections today (5th Sept)
14:20 Perth; Minella Trump (10 tips)
14:30 Fontwell; Bigbadmattie (7 tips)
