What I have noticed and what I do not understand is that on many races (especially after january upgrade) there seems to be lots of volume, thousands displayed and traded on both lay and back side, but it is nearly impossible to get even a small order matched if you don't pay up. I am sure that something is going on... What stops bf from allowing HFT algos into the exchange? In financials markets they are well established so why not here?

That was odd, tried to back Sulis Minvera before the off, unable to get filled. Just before the offical off price plunges in and it wins!

Carbon copy in the next race. Obviously a coincidence, but it does make you wonder if the smart money is being masked or hedged somehow.

It's the "Mad Bomber" of course... masquerading as a betfair trader using betfairs money (slush fund allegedly) to try and stop, frustrate, drive everyone crazy so they have to get a Betdaq Account.... ;)

should have posted here

Originally I wasn’t going to post up the details on the forum of what I received from BF and chose only to send the details to people that PM me. I’ve had so many people writing to me to explain that I thought it would only be fair to post up the details.

Basically, as everyone will have seen, I make it clear in my posts that I'm sure an entity controls the front of the market. This I accept if its on a level playing field but I 110% believe it is not a level playing field. The guys that have posted in this thread who said they don’t understand how thousands can be getting matched and then against their bet it goes the other way I fully understand, which is what led me to basically ask BF if it is possible to self match my own bets.

As I so strongly believed it happens, I thought that who ever it is must have at some time approached BF with a proposal that would benefit both BF and the entity. Therefore I took the same approach. I decided that if I selected a liquid market, I would have no chance of getting a reply and there it would have no gain for BF. Therefore I decided to pick out a market that has no liquidity and offer to add the liquidity to attract “punters” and “want to be traders”. I thought the only way to attract people however is to make a market look active (matched bets) and therefore advised this would be what I needed to bring liquidity to that particular market. This therefore would therefore be profitable to BF because an active moving market is what attracts punters and traders.
Two weeks later I was contacted saying that usually BF look out for people working in this way, but as I was a special case they agreed that it would make an allowance against my accounts to allow me to trade this way.
So in short, It is possible to self match on BF? Yes. Does it happen on the horse racing? I personally believe, yes 200% but I can’t prove it. Euler asked which markets I think its happening. My simple answer is, every single market.

The above would also explain about that crazy bomber. What bomber? If you had the ability to drop a 30K bomb against your own money for 25K and drop the price against the other 5K, 5 ticks!

what we all have to remember is betfair is a completely unregulated exchange. It can do what it wants within a broad set of guidelines

Hi Steven

Why did Betfair regard you as a special case? :)

What would you say the advantage of self-matching is? Is it to give the false impression of activity in a quiet market in order to attract money to that market?

Thanks

Jeff

Self-matching would inhibit true price discovery as there appears to be action and money waiting to be matched when in fact nothing is happening.
