Betfair queue

[winner32]

When you place a bet and are placed in a queue for your odds to be matched if lets say an hour later you go back and the bet has still not been matched how do you find out how near you are in the queue for your odds to be match. Is there any software you can get or set something up on Betfair to help you with this?

There's no way via the Betfair API to find out where your bet is in the unmatched queue. You can guesstimate your position by the amount of money available at your price before and after you place your bet. So let's say you place a back bet for £5 at price 3.5 and there's already £100 unmatched at 3.5. If there is £105 unmatched AFTER your bet was placed, then you can "assume" that your bet will be at the front of the queue once the first £100 has been matched. But it's not very accurate because the markets change so quickly.

Basically, if you want to guarantee your bet will be at the front of the queue, you have to be the first to undercut the competitions' prices. Then it becomes a race to see who can get their bets in first. And that's why the markets are so competitive.

Position in Queue - Advanced Cymatic Trader

The first software to reveal the estimated PIQ (Position In Queue) is Advanced Cymatic Trader, you can find it in the Betfair App Directory:

Advanced Cymatic Trader | Betfair App Directory

It uses the full API and has received Betfair's Approved API Solution status.

Oh and it also happens to be FREE!

The Betfair API cannot reveal the position in queue. If your software do some guessing, then it is of very limited value. If it provides reliable data (I have huge doubts the position is real, not smart guessing) then I will install it today

You should prove your words

Hi AlgoTrader,

Yes, that is correct, as I mentioned it is the estimated PIQ. It is mainly calculated from available market data but also incorporates estimates from a proprietary algorithm whenever an exact queue change cannot be determined from market data.

I believe it to be more than accurate enough for most needs. The feedback that I receive indicates that traders quickly wonder how they ever did without it.

Best wishes,
Gavin

When a new market appears, then there may be hundrends of thousands pounds lay at 1.01 in 50-100ms. I can be first in queue or there may be $100,000 in front of me. And no algorithm can say what is there. The queue position is of interest only at 1.01, sometimes 1.02. For other coefs it is quite easy to guess and of little value. I don't care of what my position is at 1.5 as coefs are quite volatile at such prices

Agreed, if a '1.01 battle' were to occur between competing automated robots in the first few milliseconds of a market's existence and if you were participating in that battle, then you are unlikely to generate the best PIQ information in that brief moment! A slightly obscure example perhaps

[birinhos.]

you can have the estimated PIQ looking to the money that is in front of you at the place moment and then looking to the volume evolution (of course programs do this automatically ). But if some bets ahead of yours are canceled , there is no way to know that, your bet will be matched before PIQ gets to zero.

It is very useful for example to trade in soccer intervals you can predict if your bet will enter or not and anticipate the close ...

[AlgoTrader]

I have Betfair emulator and I know estimating position in queue is difficult. People's behavior cannot be easily modelled, I know the worst case (no stakes were cancelled in front of me), it can be easily monitored by subtracting initialTradedVolume from currentTradedVolume. If the diff is bigger than money that were in front of me at bet place moment, then the bet is fully/partly matched. But the method works very bad when markets are driven by panic. Panic is mass bet cancellation, it can start abruptly and can stop abruptly. No emulator can reliably detect panic and predict how much bets were cancelled in front of me.

For some situations, especially pre InPlay we can set that cancel rate is zero and no bets are cancelled. But it does not work InPlay so good.

When one changes the stake of an existing bet, does the PIQ of that bet stays unchanged or does it get placed at the end of the queue?

If you increase the stake of your existing bet, then the additional stake is treated as a separate new bet and goes at the end of the queue. The existing original bet retains its existing queue position.

If you reduce the size of your existing bet, then part of the existing bet is effectively cancelled, so I believe that the queue position of the remaining part of the bet should not be changed.
