If you're always updating them when the price moves, and always placing them X away, then you might as well put them at 1.01 and 1000 because they'll never be hit?

But otherwise your logic is sound and this place/replace method is the way to do it. One other small issue, the place/replace on your sp bet needs to allow for some sort of threshold. If you do it too often then #transactions can be an issue but it also increases the chance the race will start between the cancel and the replace, or the place new/cancel old whichever way you choose to do it. There's quite often an ultra late move that triggers a re-stake of your sp bet. I'm assuming Guardian would have this potential gap when you could have no bet or two but they'll even out. The method I use allows transactions to be grouped so that none or all are processed by BF (my cancel and replace go though as a pair) but I don't think Guardian has that functionality so it could be a limitation you have to live with.

...If you want a clean-ish hedge at bsp then rather than calculating the stake at best reverse price, calculate it at the mid price because BSP will be closer to that than anything else.

Why is the "Take SP" option not working as expected?

I placed a £100 bet pre off and then I place a £100 lay bet way below the current price and select "Take SP", why does my Lay bet stake come out at less than the £100 I selected, and not get fully matched, only £78 was matched?

This is in Practice Mode, would it work properly if trading Live?

Also the Log does not record or show the SP lay bets that were matched.

22/08/2021 15:10:00: £ 100.00 Back bet placed on Fix Sun at 3.75. Fully matched at 4.1. Ref: 10007
22/08/2021 15:10:04: £ 100.00 Lay bet placed on Fix Sun at 3.35. Entirely unmatched when it initially reached the market. Ref: 10008
22/08/2021 15:10:05: Modify bet persistence 10008 from 'Cancel' to 'Take SP'


22/08/2021 15:10:12: Market has been suspended
22/08/2021 15:10:13: Market is in-play
22/08/2021 15:10:13: Market has been unsuspended
22/08/2021 15:14:04: Market has been suspended

Its working exactly right, it will use a stake so as not to exceed your original liability

£100 @ 3.35 = £225 liability

£78.33 @ 4.0 = £225 liability

If it didn't do that you'd have no control over the liability you may be accepting

So how do I get around this? Its sounds simple what I would like to achieve. I just want to put in a Back bet pre off and then take that Stake back out at BSP.

Hi All im using the new place lay Spbet.
I can get it to work when using liability and setting a max liability
however when i select net stake there is no option to set the net stake that want to lay at so the bet is not placed.

How do i get it so place the lay bet with a net stake.

On the parameter select Maximum "Entered Max Price Limit" enter your max odds then Liability "Fixed Liability" and enter amount

you dont get my point laying to liability and max price is fine
but when want to lay to a net stake there is no option to enter the stake that you want to lay.
so say i want to lay a net stake of £5 there is no option to place this.
yes can choose max price limit but cant say what net stake want to set rather than liability

Hi Dallas - I hope you can help!

I'm looking for automation that will Back at SP (More than one selection if possible) and have a max odds limit of 200, even better if there is also a rule that will also Back at SP in the PLACE market, if the WIN market is no higher than 200 and no lower than 8.

Is this possible? Does it already exist? Can't seem to find anything that can be adapted?

Thanks in advance!

Since this example was created a few years ago a specfic rule now exists to back (or lay) at SP (5th and 6th rules down in the list)
https://www.betangel.com/user-guide/rule_types.html

These are the same as placing SP bets via the Betfair website and when used on the parameters tab you'll be able to set your limit

You can also test prices from other markets but the SP needs to first be known, so the closest you could get to that is place the bet as the race turns in-running at the SP price but that means there is a risk its not matched 100% of the time ie, if a horse gets off to a flyer and romps home

Hey Chris

Although, the above appears to be a simple strategy, it certainly can be very effective, particularly, if you pick the right type of races, with the right number of horses and odds are within a specific range.

Good shout for sure! Do you do this manually at the moment? If so, have you had much success?

Regards

Super
