Well laying makes it even easier and less risky to hit the 30k target, I think you will find it is changing the sport from football to horse racing and laying 30/1 shots makes the difference, but you are still no where near risking a million, Lay 666 straight 30/1 winners in 111 days and you will have lost a million, but that is little unlikely.


I don't agree with this 3% profit thing either I think it is a fair bit higher than that, I know nothing about football, in fact I could only name one current England player and certainly do far better than 3% and with very little risk.

Fair enough. Thanks for your reply. Whatever works is the way to go. The bottom line is the profit/loss account. Good luck.

3% is a massively lucrative proposition over the long term and on here it is relatively easy to turnover a large amount of money.

Of course in a relatively short period of time or sequence of bets one can show an ROI many times better than my hypothetical 3%, but the more you play the more likely it is you mean revert to your actual true edge, and that is the rub ultimately, the more you play, the more you need to play (earning a living) the more likely you approach that true figure and that leads me on neatly to the point below.....

On a sport such as mainstream football, those 3% edges (likely much higher because of BF's commission) definitely don't exist. If you could avoid the commission that edge would be 6-8%.....that would be a virtual license to print money and there would still be a reasonable statistical probability you could go bust along the way.

I'm not saying you can't make it pay but being ignorant to the resources you are up against makes me seriously question the likelihood of someone being a long term winner ;-).

I wouldn't necessarily go along with your suggestion that " the more you play the more you need to play. "


I would respectfully suggest that with experience that a pro gains, he, or she, cuts their plays to an absolute minimum but ups the ante. No?

ericster,

I know you understand my point(s) from discussions we've had in the past.

What I'm essentially saying is that 3% edges (again don't forget the commission, the 0% books have it priced in so no advantage there) aren't just lying around here on a daily basis in mainstream football markets for someone to take advantage of, sharps bet very selectively and stake usually using some form of Kelly only when they are sure it is advantageous over the market.

Assuming you are a 'sharp' identifying value, do you really think with all the automation and market making resources out there you will be able to snap up lots of value without the market adjusting and eroding your margin? & then don't also forget 'variance', even those that can identify value long term can go bust in a long losing streak.

So many on here are simply just taking punts on anything and everything that BF has to offer, edges everywhere - and if you are paying your bills with BF how tempting will it be to take risks and blow your bank betting in markets you have no advantage over.

This is a HARD game; underestimating it or relying on 'systems' will find you a one way trip to the poorhouse.

I'm not sure that I understand your post or why you posted it.

Can I just say that I think you guys, and I've been there, seem to spend countless hours crunching numbers driven by words like margin,percentages, tying yourselves in knots with results that happened last week, last month, last year.

You over complicate imo.

Keep it simple.

If you have any sort of an inclination that something might be occurring and then re-occurring , seeing any sort of a pattern/trend/whatever you want to call it emerging, go after it single-mindedly and you don't need a calculator to see if it's working. Just look at your a/c balance. It sinks or it swims.

And by the way I would strongly suggest that you won't make ANYTHING work until you stick to it,

Interesting posts, not sure we are talking about the same thing as I am coming from a trading angle and maybe your 3% is a betting number?  But I am also going to guess that you will tell me it makes no difference as it depends on the value obtained?

Have seen many posts on here over the years on this subject and guess the general theme of them would be getting more negative over the years, it is for that reason I am grateful that many of them go rite over my head, still remember 45 years ago at school thinking "who is ever gonna need this algebra cr@p"  I don't disagree with a lot of what you post, but do disagree with your comment at the end of your post about the 5 ways people win on Betfair "if you are not one of the above you are paying for the above", you seem to only see the negative, have to much reliance in your figures and little faith in what other methods produce.

17 years ago when I was new to exchanges if I saw a thread like this one,  it would start me thinking about ways to create a system, many times while walking the dog or falling asleep at night I would think of a way doing it, only to find out that when put down on paper something was amiss. I knew if it was possible no one would ever give away their systems, but remember thinking that maybe someone could just be kind enough let me know if it was possible.

Well I am happy to tell you that you what I would have liked to have known 17 years ago that it is possible. But I also agree with nathanr that football is one of the easiest sports for compilers to be spot on mathematically with prices at any given time before or in play, but maybe with a little help from nathanr I can show you what they don't have control over.

nathanr as I type England are 7.4 to win the World Cup (101.5% market), if I bet £100 on them and hypothetically did that 100 times in an exact same situation and they won 15 times of those 100 what would my ROI be?



Ericster ..I would respectfully suggest that with experience that a pro gains, he, or she, cuts their plays to an absolute minimum but ups the ante. No?


Being selective is the biggest advantage you can have, but for me size of bet depends on the market, two golf markets last 4 days I used completly diferent sized stakes as one a lot less liquid than the other, and could give away lots if needing to get out of a trade, I always pay more attention the loss than the potential winnings.  Pre off football market would use larger stakes as will do in The Open golf in a couple of weeks time.

As you say self discipline is good as well of course, bit dangerous being on any betting site if you do not have discipline.

the size of bet IS/WOULD BE dictated by the mkt obviously but at the level I'm at right now, barely out of the two-quidding, I manage. Would love mkt size to be factor. The dream lives right now.

"not sure we are talking about the same thing as I am coming from a trading angle and maybe your 3% is a betting number"

It's just the edge/ROI/yield (for me all interchangeable as a straight bettor ie bet and leave it, rather than a trader). If, let's say over a football or flat racing season, you bet £10,000 and make a profit of £300 (ie get £10,300 back), 300/10000=3%.


"as I type England are 7.4 to win the World Cup (101.5% market), if I bet £100 on them and hypothetically did that 100 times in an exact same situation and they won 15 times of those 100 what would my ROI be?"

true price=6.67 (100/15)
price obtained=7.4

Edge/ROI=7.4/6.67=1.109 (ie 10.9%)

With market size I hope I did not come across as if I was placing big bets and needed there to be lots of money in the market to accommodate me, that's never really a problem.Laugh but even if it was a £2 bet you wanted to trade out of in a in-liquid market it will cost you to get out because of gaps in the prices. not so important in mainstream football, and a trading thing rather than a betting angle as well I suppose.


After 17 years on here full time I tend to think of things from a trading side, but I do know the last time I placed a bet on here, and by bet I mean backing something because I felt it was good value and did not intend to trade out. The bet was approx summer of 2006 on Leigh Adams to win a round in the world speedway championship, placed because he was riding on his home track and the odds did not represent that, I let the bet run the whole way and think I won £14!! he was 7/1.  £1000's, £100's or £2 the principle should always be the same only bet what you are really prepared to lose.

I would put aside a betting bank and divide it into bets that don't mean too much and see where it takes you, betting too big or from your pocket and you will miss bets that you know deep down you should have taken.

And that's another old chestnut.

Staking Plan.
Fixed stake or percentage?

Fixed stake might be considered the real test but even with percentage betting it would soon become apparent if you weren't getting anywhere.

At the moment, mkts permitting, I intend to stake a percentage of my bank. Right now I'm trying to build. I won't be throwing my hard earned at this. Also, my targets are modest. Yes, of course. 100K pa would be nice but if I could find a way of supplementing my pension with a few quid a week when I retire that would great. Assuming I live that long of course.

First glance and I thought I ain't gonna understand this, but no problems I did, well explained, my non mathematically minded way was 8500 loses divided by 9600 wins = 11.46, I was close.

I suppose percentage you will be placing smaller stakes on your winning bets if you expect losing runs, am sure someone can give good advice on it tho, just takes a lot longer to get your answers now than it used to.
By:

trebor,
thinking about what you've said, and not reckoning on losing runs, I've thought about, after a win calling my bank ten individual bets, then, if I lose one my bank has nine bets left, counting down to eight seven and so on,on the premise that if it runs out it was a turkey anyway.
By:

When: 02 Jul 18 16:17
Andriy, nathanrh or anyone,  here is a question then, and I don't know the answer but am pretty sure we will disagree.

I place a bet of £1000 because I believe the odds are going to move 2 ticks in my favour to gain £100 green after trading out. it is a match odds football market.

I have 27 instance's of placing this bet (certainly not all for above stake) of these 11 made the two tick profit, 8 made a one tick profit, 7 scratched and 1 loser of 20% of stake, so £1300 winnings, £27000 staked, what would the ROI be?

Great to see some really interesting responses on this thread - I will add some more of my thoughts later, however trebor.....

2 ticks makes a green £100 profit from a £1000 stake, what were the prices taken?, the arithmetic looks wrong ;-).
By:

It's the draw in match odds, 3.50 dropping to 3.40 for example.

When: 02 Jul 18 18:14
With you now, my adding up is wrong, would have probably picked up my mistake if using my stakes, but I have used all different stakes, plus I have traded the correct scores at same time as connected of course.


So in reality I would have used the green on the draw and taken it in-play, backed over 2,5 and one maybe 2 other scores, but for this example we will say I laid off for £1000 and greened match scores.

just curious.

Are you talking inplay here or before the off.


I had a go at a similar thing with the nil-nil leading up to k/o.
Sometimes, when the pink side of the mkt seems  weak you can go for a quick one but it IS a minefield imo.

Before Kick off, I would not worry about the weight of money, but lets say the fav is drifting then either the dog or draw has to shorten, fav drifting means less goals expected so favour's the draw shortening, unders will give clues as well

Greened up the win or lose is just £15 a tick, and it is a fully formed market which means you have liquidity to get out normally for no loss.

I highlighted this trade tho because of the discussion on this thread about 'perfect markets' and not being able to make more than 3% ROI, those conditions create good trading conditions imo, and I also chose this trade because of its incredibly small ROI, but is it??

The stake may be £1000 but how much of that stake is really at risk, of course never put any amount of money up if you are not prepared to lose it all, Betfair could go down. If this was a straight bet on the draw then you can expect to lose the full stake more times than you win, so ROI has a use. But when trading trying to make a couple of ticks it seems to me more of a evens bet, make £100 or lose £100 but with an advantage on the winning side, plus if it is a loss you can make it just a £30 loss.

So am I wrong, I know I will get told I am, but you gonna have to convince me.
By:
ericster
When: 07 Jul 18 11:16
trebor,

obviously if you're looking to green up and not stay in all you're really risking is the value of a couple ticks, as you call them. If you're doing this on a regular basis you must be getting something out of it and if you are I can't/wouldn't knock it. Profit is profit. Good for you mate.

Many years ago someone said to me in one of the bf 4ums, and I quote, "It's not about winning, it's about not losing." I've never forgotten that. Think about that for a moment.

Yes of course it's about winning but what if you never EVER had another losing trade?

You'd have to have winning days sometimes and how cool would that be.

So if you're making a profit and you're happy with it GO with it and good luck.

trebor,

So as I understand your strategy;

1. Back the draw for £1000.
2. Lay the draw as soon as the price ticks downwards (for £15 profit on all selections).

My question:

1. In a liquid market how many minutes of the game (rough guess will do) have to elapse for you to get your lay matched?

And therein lies the problem. Markets on here typically adjust using fairly well understood time decay principles, the draw price gets shifted downwards on a fairly consistent time-delay curve (the rate might be slightly adjusted depending on how the game feels but ultimately the curve works its way down to 1.01 assuming no goals are scored).

I just don't see the 'edge'. Your system works as long as you can trade out, but there will be far too many matches with goals in the first 5 minutes so how can you consistently identify those matches where there won't be an early goal?

Cheers.

By:

When: 07 Aug 18 18:18
So effectively you are trying to trade on pre-match price movement (in this instance the draw).

I still don't see the edge unless you have some sophisticated method of predicting that a price will move the way you would like (and by sophisticated I mean something the market doesn't or won't have accounted for).

Sometimes the market will move pre-match the way you want, other times it will drift and others you most likely just have to scratch the trade. All of those will even out in the long run and you will lose to your commission rate. The best I can say is that at least you aren't totally chancing your arm by allowing a position to go in-play.....

Tell me if I'm misunderstanding? or if you are massively in profit over the last 5-10 years. If you are actually in profit be sure to tell me (privately) your selection criteria, I'll be retired in a few years if it holds up ;-).

Cheers.

While I don't believe you can operate a system based on a rigid selection policy,  a selection process can be devised that is organic and takes into account factors other than recent form/historical data/teamsheets.

i have just started in december a live trial at minimum stakes of a method of selection to lay teams that is so far scarily positive.

it has a strike rate of 88.68% (47/53) with average odds of 4.93 (79.72%), with similar figures previously paper testing and back testing.

so far, it is 20.95 points up at level stakes taking into account 5% commission.

I am now waiting for the wheels to fall off.......................

i know the forum is full of sceptics - and rightly so - therefore i will put up the selections highlighted for tomorrow.

this is usually the kiss of death for any method, but as i'm waiting for this method of selection to regress to the mean anyway, i'll tempt fate.

Lay Ural
Lay Levante
Lay Heracles
Lay AC Horsens
Lay Caen
Lay FC Zurich
Lay Reims
Lay Aris
Lay Charleroi
Lay Torino

I lay 30mins before kick off, providing the odds are in my desired range, therefore one or two of these may not be layed.   I can hear the howls of derision already about aftertiming etc. but it is what it is and you can take this at face value, or pull it to pieces, its up to you.

A while back there was a thread on the footie forum laying away teams (in the 5-6 range as I recall), it went down spectacularly and the author just couldn't accept he was making selections blindfolded with a dart.

like i mentioned earlier, i am moving away from looking at fixtures purely in the quantitative sense.  i look more at the qualitative research of fixtures and don't need to have an in depth knowledge of the league.  as you may have already worked out, it is more of a ratings based selection process.

your input is appreciated and as you correctly state, i am waiting for it to revert.........
