Laying at half sp

[GaryRussell]

""because BA "forgets" about offset settings when the program is closed or the market is changed which you probably have done since.""



Talking about the market changing Gary,do you mean if the market gets suspended then the offset will cancel but the back bet would still go ahead?

I mean when you open a different market in the same tab. Market suspension will not make it forget the offset settings.

Thought you did..lol..it would sort of defeat the object otherwise

Cant get my head around these quick picks and auto select but the penny will drop eventually,a bit more studying i guess.

I can see I've opened up quite a can of worms over this

As we are now naming sites and whatnot, has anyone heard of the Back to Lay auto bot?

It's a spreadsheet that works in conjunction with BA. So far I can't get it to do exactly half sp odds, though!

Today in the 1:25, for example, it backed at 9.24 and layed at 5.1. Bloody thing went on to win, too!

I can't get in to look at the VBA codes, but maybe someone more experienced would be able to decipher it?

The sheet is working fine and has not VBA at all.
The half sp is calculated from fractional odds and not the decimals you gave in your example , so the half of a sp of 9.24 is (9.24-1)/2 = 4.12
You should have read more carefully the instructions Jamie

Good luck with those John,you can also use the BACK-PL50-SP trigger but you have to keep ur odds up to say around 900 on the back so the SP gets taken.Although you wont be able to stop the SP being taken if its below 2.02,and it will effectively be ajust a back bet therein afterwards,you can play with stakes below the minimum this way until you feel comfortable.

Cheers brumbie that is another formula to bear in mind although I think i'm comfortable now I know it works. I will be using it on the days I'm in work and taking the sp and back lays manually at the weekend.

You could have told me this sooner! Thanks

I have just used formula BACKSP-PL50 to back at SP and lay at half the odds for double the back stake. I placed a £2 stake in the S cell and minimum odds of 4.1 in the R cell. The SP bet triggered at 6.8 at the start of the race and placed a lay bet at 3.9 but with a stake of £3.49 instead of £4 which would be double the back stake. Is there something I have missed? Any help would be appreciated Oh and yes it dobbed by the way!

£3.49 would be the correct stake for a level profit to be spread evenly (horse wins or loses but you win either way) for a £2 @ 6.8 to 3.9 close. If you closed the bet at double the price/half the odds you would only win if the horse lost.

If thats what you want to do you just need to amend the trigger to BACKSP-P50

I'm a little confused there! I can place a back bet manually at say 6.8 for £2 and then a lay bet at 3.9 for £4 and as long as the lay bet matches in running i make £1.90 after commission whether the horse wins or not, so I don't understand why it placed a lay at £3.49 instead of £4. In fact I've just used exactly the same formula on another back to lay from an SP of 44.0 down to a lay of 22.0 which matched in running and this time it did place a lay stake of £4 which is double my back stake. Does it not place the lay stake at double the back stake every time?

[Captain Sensible]

You place a back at 6.8 for £2 so if it wins you win 5.8 x £2 = £11.60

if you lay a bet back at 3.9 for £4 your loss on that horse is 2.9 x £4 = £11.60 therefore if it goes on to win you'd break even, if it lost you'd win £4 less the £2 you staked i'e win £2

Ok I have just placed a back bet at 44.0 for £2 and then placed a lay bet at 22.0 for £4. it matched in play and the horse didn't win and i won £2. Are you saying that if that horse had won the race I wouldn't have won or lost anything? After the lay bet had matched it showed a £2 profit on all selections regardless of which horse won. I was under the impression that I would still win the £2 even if the horse won. In fact I am pretty sure I have dobbed a couple of horses previously which have gone on to win and still made my profit.

If you lay a horse at exactly half the odds for double the stake you will not win if the horse goes onto win, simple maths.

The reason you would have won with odds of 44 is due to betfair's odds increments, half odds of 44 is 42.5 but as 42.5 isn't a valid odds increment it's stepped down to 22

Ok I have just backed and layed a horse using the formula BACKSP-PL50 backed at SP of 6.80 and layed at 3.90. Back bet was £2 and it triggered a lay bet of £3.49. This showed a green up profit of £1.42 on everything apart from the horse i backed and layed which showed a profit of £1.41. The horse I backed and layed went on to win and I made a net profit after commission of £1.41

Ok I think i@ve got this now!! The formula placed the lay bet at £3.49 to make sure I got a level profit? If I had placed a back bet At £4 instead of £3.49 would have just broke even with the horse winning?
