Hi Peter, I just found this great post! I don't suppose you have an update on how the strategy is going? Im intrigued... :D

Yes but Euler. You will note that I am still here a year on and a lot more experienced even though in my first ever post I asked if it were possible to make £300 a day. Problem is that if you ask that question it can be taken in two ways. Without actually knowing whether the person is willing to learn or not sometimes the experienced traders tend to draw a negative to the post before its even started. Unfortunately Letiss gave me some s~~t,amongst others, when I joined and my simple question was 'was it possible?' The answer should have been yes if you work hard and learn or simply ignore the post. I am still here winning and losing but perfecting and its coming together I am pleased to say. The be all is most people are looking for a get rich quick idea, particularly now a days so just a little sympathy doesnt hurt sometimes. Afterall for every lay you need a backer and every back you need a lay. Newbies can provide good fodder. Just my opinion that is all.

Hi
I had a defined exit plan with this strategy and I exited on the 11th April. The P&L started to level off and start to trend downwards and I felt it had run its course (no pun intended!), I'll update the graph when I get time (its on the VPS and its running at the mo)

Hi Peter,

i just picked up on this thread and its a very interesting one for me as about a month ago i identified what i believed " may " be a strategy. It involves laying horses in running on auto which is something i think you also do.

i have now recorded around 800 races where i have placed bets and am trying to identify whether it may be an ongoing profitable strategy. On Eulers guidance i have taken my cumulative profit as a percentage of cumulative staked to see where i am at and what he basically said was if the % starts to level off and stops jumping around then it may be a goer. After 800 races its at around 0.9% and fluctuating from 0.8 to 1.1 so i think its pretty stable. I'm only doing £12 stakes and laying at 1.53 so max liability per race is just £6.36. Very interesting to me on your graph is that from around 6000-7000 races you had a big downswing and i have a number of questions :

1) Is 0.9% ( cum profit/ cum staked ) any good ? i have no idea ?

2)Every hunderd races or so i tweak it ( remove certain race types , green up conditions go in , change unmatched bet criteria , change the price i'm laying at etc ) and i dont know if i'm fiddling too much and should leave it for a bigger sample.

3) Were you worried that 1000 races went by and the strategy looked like it was failing or did you just stick with it or make changes at that point ?

Anyway , dont want to make this an essay so i'll stop there. Thought it was very interesting Peter as i am trying something similair

Hi
Maybe Peter can comment there; it's not a metric i use, so Im not sure either whether that is good or bad?
The image below is an update on that particular strategy.
There is a lot of talk on the forum as to whether something will be profitable long term. If you look at the update, my gut feel was that this was starting a downward trend.
There was one particular course from a total of 84 (Wolverhampton) that was producing a large proportion of the profits initially. This produced >£1k and went from position 1 to 82 and finished on -£216 over exactly 1000 races.
You can compare that to Naas (87 markets £647 (7.44 average) or Bath (141 Markets £862 (6.11 Average)
At the end of the day, someone is losing that money and they are going to be taking measures to stop the loss. I was just very surprised to see Wolv drop so fast. The stakes were linked to individual profit on each course. Once a course went into the negative,the stakes were reduced to minimum and where a course was doing well the stakes were increased.
Stoping losses is as equally important as making profits. If you dont take anything else from this post. make a mental note of this line!!
Anyway, it traded on 10,810 markets and produced a profit of 3,865.04 with a positive strike rate of 4.18%

To answer your specific questions:-
1 Not sure; Peter may comment
2 I personally downloaded the Betfair P&L into Nigel's spreadsheet and the stakes were calculated for the following day. So no I think you are doing the right thing.
3 To be honest, I was fairly confident this would be profitable overall and once I was using betfair's money, I wasn't really bothered if some of the profits were lost. If you think about it logically, there are only two families of strategies; Back or Lay, everything else is just a variation of a theme.
I think its important not to measure success on profits alone, you should also consider how much new knowledge you have gained in the process too
Anyway good luck to it.
Regards
Peter

PS I wanted to take to reply to this as there had been some negative comments on using automation; no its not perfect, but as my dad used to say "A bad workman blames his tools". You have to have a logical approach to implementing things like this, Concept; Test and dev, Implementation and Production. Put safeguards in to your strategies, use test mode and have a minimum in your betfair wallet.
I was sorry to see someone lose £500 this week using automation. Its a tough lesson to have but it could have been avoided (PS I had some tough lessons early on too!)

Thanks for the reply Peter. I have identified a type of race that does not work with the strategy that i deploy so i knocked that on the head and now i am producing small but consistent profits at £12 stakes. I could scale it up by x 10 and would still get matched easily. I only need to win 40% of races which is basically what is happening so i have decided to take on board your comment of eliminating losses before i ramp up the stakes. i'm going to try and get my strike rate up ( ie eliminate more losses ) before i ramp up the stakes.

Just one last question - why have you stopped your strategy if its a winner ? What made you think it would not carry on indefinetly ?

Excellent, hope it works for you.
I havent completely abandoned the strategy. Its just on pause for the time being.
As I mentioned; the vast amount of strategies are just a variation of a theme, so i will revisit this.

after only having the software a short while now I would have to say that I think the automation function is a fantastic tool which can lead to all sorts of possibilities,it was suggested to me when looking for some help setting up a rule that I should take time to gain knowledge of the software and the automation and to access the practice mode for result finding that would justify my progress,"thanks again rodger" but in reading this reply it struck me that my first mistake was not learning enough about betfair ,so this was my next port of call I have simply examined as much resource,feedback,instruction,and information regarding trading within the set limitations of betfair as I could and I have to say that it simply opened the door to how my approach to automation would start and progress ,some of the theseis papers written on betfair are remarkable and very insightful this has helped me make decisions so much quicker and given me independance of thought when writing down on a sheet of paper exactly what i want to create ,test,and hopefully make work for me yes i am a newbie and i know my opionion will not mean alot but reading the forum posts will relate a feeling of mixed message from newbies,experianced and people who have given up and people who have been successful all i wanted to say to anyone starting new is learn the size of the pitch and its boundarys before you get the ball because it has helped me ,yes ,helped me dont look for answers look for help ones given the other is earned

Your 100% right there. I worked this out sometime ago and when i did it became the key for me. No-one that has worked hard on a strategy is going to tell you what it is and why should they ?

Some of the pro's on here are very generous with their posts - they actually do provide the answers but you have listen and then work out what they are for yourself. Mugsgame , Jolly Green , Peter Le and particularily Euler all offer incredible insight into what it takes to be a proffessional - all you have to do is listen and apply a tremendous amount of hard work - you get nothing for nothing.

Seek and ye shall find.................

It actually becomes quite enjoyable when you start building something from the ground up. Its like nurturing a plant from seed!

Yesterday I was running a "Lay to back" system that I had been tweaking on and off for ages..
It waits for an awful lot of conditions to be met before it It places a lay and then offsets looking for large odds. The first race I tried the new version on was at Windsor, it laid a horse called "Cafetiere" for a combined total of 9.90 at the bottom of its range and then managed to get £4 matched in the offset. It doesn't use greening

I didn't catch it right at the top, but got £4 matched. According to Timeform it traded at 200 at the top (although looking at the video i recorded I thought it peeked around 450?

I can now use that profit to develop the system risk free
You only need a couple of these a month :)

I can understand why you would remove certain tracks from in-running automation but does anyone do it for pre race?

I'm pretty sure some people dont trade tracks like Wolverhampton due to the extreme volatility. Runners can be both big steamers and big drifters all in the space of a few minutes which ruins the approach of " trend " traders. After a while i suppose you work out which tracks suit your style and which dont and it makes sense to not trade the ones that dont fit.

Ive pretty much mastered BA bot creation, aside from using spreadsheets yet anyway. I have made bots before for others things such as virtual dogs and the dating nice so I had that as an advantage in learning Betangel.

Can be a bit frustrating sometimes. I'm not doing it to win money however. I just like making bots and I think thats the best attitude to have. Then if I do win money down the road that is just a bonus.

However, I do see big potential to make a lot of money still.

I bet on a dog, I think it was a dog, called Harambe. 2nd fav @ 14/1. I just knew it would win. SImply because it that price was out of place looking. I meant to back for 70 pence but I entered £70 by mistake. I back out back down to the original amount I wanted but of course it came in. LOL

So, I can so the potential but I am not expecting to make any money per se. Just takes a lot of testing, patience and a bit of luck. Some people will get their lucky break some wont.

I find in general that the more complex I make the bots the worse they do rather than the opposite. Since they start to rely more on whether they will match or not, ETC. As I said on another post, I think it's better to have an idea first then make the bot for it but I guess some people have done it the other way around with success and it is fun making them anyway. :)
