The min fill size worries me a bit.
Does this mean, that an order that sends a min fill size of say 50k, will get nothing matched unless 50k is available on the exchange ?
When did this min fill size parameter become operational ?
There is a team sweeping up 100k orders on the T0 world Cup cricket, getting filed after 2 secs.
I wonder if they are submitting bets 3 secs before action (having sub-accounts fill liquidity), which they cancel if they dont want the bet, as limit isnt met.

I've done some work for bodies related to integrity and have seen direct evidence that 'insiders' are using this sort of technology to their advantage. Whether it is still going on is difficult to know. but it's like jelly. It's difficult to stamp on.

When did min fill size come in ?
Sceptics would say Betfair are in cohorts with teams doing this, as they get 40% PC.

Failing to get anywhere with Slack ?
Clearly a Luddite - can anyone please provide a link to the #askbetfairanything channel.
I have installed slack on iphone, but I cant find the channel from search.
Thx

Looking at bthe API docs, t seems the min fill size is used in this code :
[{"jsonrpc": "2.0", "method": "SportsAPING/v1.0/placeOrders", "params": {"marketId":"1.126124422","instructions":[{"selectionId":"10590221","handicap":"0","side":"BACK","orderType":"LIMIT","limitOrder":{"size":"5","price":"21","persistenceType":"LAPSE","timeInForce":"FILL_OR_KILL","minFillSize":"5"}}]}, "id": 1}]
This means stuff all to me - have asked someoone the API team to explain what min fill size is/does.
It looks v sneaky. Might have come in from July 2021.
Hope I am wrong etc.

I have been convinced that someone has found a loophole for quite some time now. Very clever on their part and they are cleaning up but very difficult to prove.Euler wrote: ↑Mon Nov 01, 2021 10:53 amWay back people worked out a loophole in football betting like this.megarain wrote: ↑Mon Nov 01, 2021 12:39 amThere is a team sweeping up 100k orders on the T20 world Cup cricket, getting filed after 2 secs.

Not so great for the rest of us though and a bit worrying if there is and Betfair aren't aware of it (or choosing to ignore.)
Thx - posted a question about Min Fill Size there.
Hi,
I have just discovered the Min Fill Size parameter on Fill/Kill bets.
Is this not a licence to by-pass the in-play delay ?
Maybe I am reading it wrong, but it seems API software can be used with other teams members to by-pass 2-4 secs of an in-play delay.
What am I missing ?
Thx
I think the #askanything channel was a once-off, but got this reply :
The point is, its been happening to court-siders at the T20 World Cup -- I am 5k miles away - so, am only looking at integrity issues.
Am sure Betfair will deny etc. But probably half a dozen court-siders can attest to the raping of the markets.

If we trusted Betfair 100%, I could suppose live with this .. but am not sure many full-timers now trust Betfair 100%You've missed the window on getting an official response but anything that relies on you colluding with other market participants is not going to last very long

I've seen a lot of complaints from Cricket traders that they are being picked off.
I've always thought cricket is odd in that a major event, such as a wicket, doesnt' create a suspend situation. But goals in football do. Always seemed odd to me.

Just to clarify the response on the Slack Channel...
Betfair only opened the Q&A Channel for a short window and they closed it this morning, so you just missed the opportunity to ask questions. They will be opening it again in the future
The response by Mo - Mo doesn't work for betfair but he tends to know the API inside out technically.
Thought that may help as you may be wondering who Mo is etc

PS I didnt quite understand what you meant by using sub accounts/working in Teams. (I have Sub accounts but there would be no advantage in using sub accounts on a single strategy as opposed to using a single account? Unless Ive mis understood soimething?
