ACCA (again sorry!)
-
Hi Guys,
First post in a while!Thought it was time I started on the Acca’s. I feel the best method for me personally is the Lay all at the start method, I presume the no lay method is probably more beneficial, however guess i’m just a wimp!
Result Bookmaker Exchange Your Profit
All win (24%) £68 -£40 £28
1 lose (40%) -£5 -£7.50 -£12.50
2 lose (26%) -£25 £25 £0
3 lose (9%) -£25 £57.50 £32.50
4 lose (1%) -£25 £90 £65
All lose (0.1%) -£25 £122.50 £97.50I found the above online, this is based off a £25 stake and back and lay odds of 1.3/1.32. I assume this is correct?
Any tips would be appreciated!
Thanks+0February 16, 2017 at 12:58 pm

New to matched betting?
My Matched Betting Academy is the best place to get started. Learning the fundamentals takes 10-15 minutes and you’ll make £15 in the process.

Sorry. Meant to say 1 divided by the odds 🙂
+0Ah ok Bigchris I see what you mean. I think most people tend to use the lay odds rather than the back odds when working out the probabilities, not that it makes a huge difference if your going for tight matches.
The probability of all the legs winning are the reciprocal of all the lay odds multiplied together (ie as you say 1 divided by the lay odds). So for example say we have 5 legs each with back and lay odds of 1.2. The reciprocal of 1.2 is 0.83333 and if we raise this to the power of 5 we get a value of 0.401 or 40.1%.
Unfortunately the calculation for working out if one or more legs lose is a bit more complicated. I have the equations written down somewhere but not sure where. There is however a thread on this site that explains all this far better than I can, but no idea where about it is, perhaps someone reading this will link you to it.
+0There’s a link somewhere on here for a spreadsheet fog knocked up to show the value of an acca, or oddsmonkey does the calcs well
If you search there are sequential lay calc spreadsheets you could use for last leg, but should be a easy enough manual calc – option A you win the Acca, option B freebet
+0Yeah like the lads said.
If the lay odds for each leg is 1.2 then probability one leg wins is 1/1.2 = 0.8333. And then the probability the leg loses is 1 – 0.83333 = 0.166666
The probability all 5 win is 0.833 ^ 5 = 0.40. So you have picked what looks like 4 dead certs and its only a 40% chance that you will win the acca!
The probability at least one leg loses is 1 – 0.4 = 0.6.
The probability that only the first leg loses = probability first leg loses x probability all 4 others win = 0.166666 * 0.8333333 ^ 4 = 0.0803. Thats assuming all the legs are independent (technically you could have a situation towards the end of the season that if one team wins then it affects the chances of the next team winning if they are both in a race for the title or something, in that case you can’t really multiply the probabilities because they are not independent).
And repeat for the probability that only the second leg, and only the third leg ….
So then the probability only one leg loses = probability only first leg lose + probability only the second leg loses + …. + prob only the fifth leg loses. You can add the probabilities because they are mutual exclusive events.
= 0..0803 + 0.0803 + 0.0803 + 0.0803 + 0.0803 = 0.40187
So your probability that only one leg loses is 40% which is quite good chance of getting a refund and that’s why we stick to low odds.
+0Great thread.
FoG what is your profits for the no lay acca?
What is your current stake and which bookies do you use ? (Used
How many accas do you get on a week ?
Thanks
+0Thanks you very much guys. That makes sense now. So you’re basically calculating the odds of each outcome that would result in one team only losing, then adding them together.
I’ve started using oddsmonkey”s no lay acca software to find my matches, which seems like a great time saver, but wanted to see the odds of each outcome from the acca with laying the last leg.+0@ mcnoodle I’m sure Foggy will answer your questions when he sees them, but I would strongly recommend you read all the posts he has made in this thread and any other he has made with regard to accas it will give you the knowledge and just as importantly the confidence to try the no lay method. I made about £4K profit mainly from no lay accas in the last three months of the footie season. Most of the knowledge and confidence I required to do this came from reading Foggys posts and from him being kind enough to answer my questions.
There is however one big difference between this season and last season. Many of the best bookies for the no lay strategy have now either withdrawn they acca offers or amended them in such a way as to make variance a much bigger worry.
I am not expecting to make anything like the money I made in the last few months of last season again, in fact if variance proves to be too great I will probably pack in doing these offers completely. I don’t really want to start down the sequential lay route.

Thanks for that
I will certainly read the comments this morning, will make for a good read
+0mcnoodle, get a calculator, or create a calculator. They will calculate the value of the acca. So usually you should be looking at acca’s that will return 10% to 20% ie the calculator will show a profit of £2.50 to £5 for a £25 acca.
Now you can write your own paycheck.
If you want to make £100 per week you need to aim to be staking £500 to £1000 per week which is at least 20 £25 acca’s or 10 £50 acca’s. So at least 3 accas per day which is doable with a few accounts and half an hour at the end of the day.
The big warning is that this is not guaranteed. This month for example I have not won a single acca so I am down hundreds. I have earned plenty of free bets but still probably down quite a bit.
There are different ways you can reduce variance. 1. Lay all up front method, 2. Lay the last leg at least, 3. definitely spread you teams around so that you dont have one point of failure, so Real should not be on every acca even if they are dead certs to win, 4. sometimes if i have a free bet on another site I will throw it on the opposition on one of the legs. 5. choose sequential games and lay everything.
I am not making much on this any more. I’m down to Dafabet and Bruce which dont even have the greatest terms and conditions. Last season I had betmclean, betvictor and sportingbet too and was making similar profits to what DaveJones has put up. I dont know if they are all still doing acca insurance with the same advantageous terms.
You want low minimum odds per leg, or no minimum odds per leg.
Anyway, I am just repeating what already in the different threads…
But just to emphasise that it is not guaranteed profit. You can go in with a bankroll of £500 to £1000 and easily lose it all. Maybe the chances of that happening are only 1%. But even so that would mean that if there are 100 ppl reading this and go in on no lay acca’s because of me, then I would be responsible for 1 person (maybe you?) losing a whole bunch load of money. And I don’t want that.
What I did was created an acca fund from my other matched betting exploits – maybe start with £300 from your lifetime matched betting profits or redirect £100 every month of your monthly profit to a no lay acca or punt fund. When the fund ran out (and it did a few times) I would build it back up with less risky matched betting methods. I think that’s a safer way than just throwing your entire bankroll at this.
+0Placed my first Dafabet Acca last night FOG.
Min odds 1.3 5 fold – i thought it was quite good odds don’t seem to be too bad either!
+0I’ve doing an acca test run since 4th August, a mix of 3, 4 and 5 folds on match result and corners, I’m about £60 up, £5 stakes. I didn’t know about the oddsmonkey no lay acca builder, just watched the video and looked at some of the accas using the builder. It seems a good way of doing accas as some of mine have been quite poor lol
+0What expected return is oddsmonkey giving you though BKK? Unsure what edge you’re getting off 3/4 folds, so how oddsmonkey would identify a positive return?
+0@ BKK I only do accas which have got a refund offer. How do you get profit from a 3 or 4 fold? Are you looking for arbs on some of the legs or are there win bonuses to be had which effectively create an arb?
+0I’ve been punting 3 or 4 or 5 folds with skybet and william hill, £5 stakes. I haven’t used the no lay acca builder on oddsmonkey yet, but I will do this weekend. I’ll post my results on Monday.
+0@ BKK if we take a 3 or 4 fold acca with Hills as an example, what do you think your edge is? You need to have a defined edge before you start placing bets. Lets say all your accas won this weekend, unless you know why, then the results don’t mean anything. My edge comes from the bookies providing a refund on 5 leg accas. This effectively is providing me with an arb. Without that refund I have no edge and would eventually end up losing money. The fact that I might have several winning weeks or months without that refund does not mean anything. Over the long term I would lose money unless I get the refund if one leg lets me down.
Now if you study football form and can find the bookies have miss priced some matches (this is very difficult to do by the way) then that’s a different story. Of if your quick off the mark and can find some arb opportunities and stick them into an acca then again that might give you an edge.
