This morning I took what was on offer at a certain price plus left some more at that price hoping for someone else to match me. A few hours later no more of my bet had been matched but a few hundred extra had been matched at that price so somehow someone had leapfrogged me in the queue.
I am waiting for market operations to get back to me at the moment.  Anyone else noticed this lately?  My initial reaction is it's Betfair's skimming cross matching bot queue jumping to skim an extra couple of quid.

I've noticed something similiar. I was first in the queue and got matched for part of my bet. Something else then got matched at that price yet nothing had shown up in my bets, someone else got it. How can that be, if I am top of the queue?

Probably cross matching but you'd have to ask Betfair how they display matched amounts for the cross matching, should really be displayed against the 'real' bets on the other options but wouldn't suprise me if Betfair included them across all options to bump up the figures.

I'd be interested in betfairs reply as it could be a good way of queue jumping if it is down to cross matching.

CLYDEBANK , was it a multiple runner market or a market with only two or three outcomes ?

hmm that's weird. Let us know how you get one with this one. I haven't noticed it myself.

It was a 2 runner market Eddie.  All I can say is that at around 2pm the last price matched as shown by the graph was at this price for approx £900. My bet was placed at 10.32.  At 11.44 and 12.00 I laid a bet at the price one tick higher so according to the graph the £900 must have been matched after 12.00.  I suppose another explanation is that the graph was incorrect.

You put your bet in-running james and there were no withdrawals right at the off?

I have recently been at the front of the queue,had money matched for say £1000 but the graph traded box is showing only   
around £700 has been matched.This has occured more than once,from what ive seen betfairs bot money allows you to jump them and only matches if no-one else is offering/requesting the price.Disturbing if someone is jumping the queue,betfair need to answer this question and look into it properly rather than just denying it and sweeping it under the carpet.

Could this be something to do in the way they match the bet when the market goes underround?

In that, you would think their cross matching bot would simply match the bettor/layer with the bet and 'cream off' the excess. But maybe its matched in another method that indicates queue jumping.

unsportingindex...they did look into it and told me nothing at that price had been matched in the interim despite the graph saying it had.

They normally just blame a lag in the graph data updating as long as it suits their purposes.

Personally I highly suspect the x-match jumps in front. Proving it wouldn't be that difficult either - if anyone will listen (that's the hard part).

Almost certainly a lag in data. It would be so easy to prove if it was occurring.

I noticed this years ago so really haven't watched it closer since cross-matching was brought in.

Markets that are slower in volume, including horses in the morning, tend to have the information updated much slower for graphs/stats.  I believe it simply comes down to betfair focusing their systems in the faster moving markets. 

Even horses takes several seconds after the race for all the data to be brought to speed.

Someone else may remember this: betfair did make an announcement two or three years ago that this lag would be present after one of the "upgrades"

Could it be that Betfair proritise "cross matching" because of the " fringe benefits" maybe ?
Cool

delay in graphs updating? bets already matched at the price you are trying to get but not shown in graph yet. then you put your bet in. graphs updated now.

A few weeks back,i had an incident were i was laying more then one horse per market, and one outsider i had a lay bet at 3.00 waiting to get matched in running anyway that would have be my hedge.The selection have been trade as low 1.80 but my lay bet never get matched, how can pass a price without getting match?
and i check my betting history the bet was there in keep mode.I guess they can match up were ever money they like, does not matter the queue.

I would be surprised if betfairs cross matching did not guzzump you.  A right pain this is. 

I complained about it when it was first introduced only to get opposing views from people that clearly did not understand the implications.

I don't think Betfair are doing this. The extra income this would bring in is not worth it, as liquidity providers would no longer bother seeding markets if there was even less chance of getting matched.

Imagine spreading £50k over 50 different markets. You only expect £4-5k to get matched, so you need a decent margin.

In a lot of 'fringe' markets key individuals are providing a huge portion of liquidity (meaning they are involved with more than 50% of the total £ traded). The incentive is already low.

If there are 2 systems operating 1 must take priority, need only be a split second
