Hi Dallas (or anyone willing to help),

Can you see from my screenshot any reason why the below rule didn't trigger?

Cheers.

sure... my gut feel is that your lay bet MATCHED = £10 is what's causing the issue. if you are laying by liability, then depending on the odds, this ££ figure could be literally anything. no pun intended, but your best bet would be to set a lay bets NUMBER > xxx bets or use a LIABILITY ££ > than ££XX. that way, you don't need a very perfect and exact match...

that said, i've been known to misread many a scenario :D

Thanks for the reply!
I'm not laying by liability though. Its just a standard lay bet and it got matched as soon as it entered the market. The Lay bets matched was equal to £10 at the time.
That said, it can't hurt to change this to greater than 9.90 and give it a whirl.

sounds like a plan... also, if it were me (and it's not!), I'd lay by liability as it's not beyond the realms of fantasy that your bet could get taken at ANY price in a volatile market!! this could literally mean placing £xxx fixed stake on odds that you'd never dream of taking. my mantra is to always place lay bets on liability for this reason - it only takes ONE!!

Thanks for the advice. The lay bet for this strategy places at fixed odds of 1.61 as that’s the highest liability I’m willing to accept. This particular bet matched at 1.15 and would have made a nice little profit had this second rule triggered at ~1.58. I had my eye on it and I did manage to grab a smaller profit when I noticed it hadn’t triggered.

if 1.61 represents the highest odds you're willing to accept, then viz a viz you have an upper acceptable liability. obviously, below 2 odds the bang for buck on fixed staking is (arguably) BETTER than staking by liability. HOWEVER, if you have an upper threshold (££), then just stake by liability to that amount and you'll seldom/ever go wrong...

just my 2c (by liability :D)

Thanks. None of this explains why the darn rule didn’t trigger though. Fresh mind in the morning might be able to figure it out.

I go with Jims call on the Lay Bet = £10 preventing the rule triggering as well.

Either go with a count of Lay bets matched, or if you may have previous lays use a P&L calc to an SV to work out your liability to calc how much to back at the back price. I do this when laying by liability so I can remove x% with the back. That way you are always working with known quantities.

It’s definitely not that. It has never stopped a rule from triggering before. Like I say, this strat only places one lay bet to a fixed amount of £10, it was fully matched when it reached the market. There were no other bets placed on the market.

You didnt stop/start or reapply the automation at any point ? Asking in case any signal was set. I have a rule at the start of my tennis automation to clear all signals and SV's, just in case they are previously set.
That would affect your time since set condition

Shouldnt be an issue with the 20s to 40s window either, unless you have loads of markets and a huge reresh rate...

Nope, automation was left to run without any interference and was the only market i was monitoring in guardian at the time.

I'm glad its not something glaringly obvious and I'm not being stupid.

I'm starting to think it could have been a mini network outage on either my side or Betfair's side. There's no other reasonable explanation? Although it still should have triggered the rule right? Even if the bet didn't reach the market. In the automation tab it hadn't triggered.

Possibly.

I'd still go with the previous suggestion of Lay bets > £x though just to be sure. If its the only lay going in it could even be > £0

Though, what happens if you arent fully matched ? Like I said before I'd lay and then calc my P&L on that player using a stored value. Then you can use that value to calc the value of the back based on the price you are eventually backing at

I had a discussion with Dallas re doing similar here

viewtopic.php?f=37&t=21985&p=234735&hil ... ty#p234735

Works fine as discussed. To create your free bet you could then just back to 100%

Yeah I see what you mean. However, the signal changed condition allows the market to settle during the interval between sets and my stake is tiny compared to the amounts thrown around on the markets so it will get matched. If i ever get to the stage where I can throw around big stakes then i will definitely need to look into this.

But for now, why didn't this rule trigger? :cry:

Yeah, I do the same on the settle, though I extend mine out quite a bit longer. On bigger stakes the extra ticks can make quite a difference on profit

Still stuck on the reason why. All I can suggest is play around with using a different condition for the Lay= £10 and see if it makes any difference - a few different ways you can cut that one. Even take it out to test, if you are 100% convinced you will get matched i.e lay at 2nd/3rd best market price

Is it possible to change this to lay either 1st set winner?
