No delay required when adjusting odds for a worse offer?

There are good reasons why you can't instantly alter unmatched back bets to a lower price, say 'from 2.1 to 2.08'.

The example below should illustrate this:

1) Submit a back bet at 2.1 on a selection (unmatched and appears in the queue on the lay side).

2) An event occurs in-running that makes the correct price on that selection to win 1.5.

3) You instantly alter your offer to 1.55 and, as it is not subject to any delay, you potentially hoover everything at or above that price that hadn't been instantly cancelled!


I suspect that you meant to ask why you can't, for example, alter an unmatched back bet from 2.1 to a higher price, say 2.12?

In that situation I would agree that a delay in the submission of the alteration seems unnecessary. I believe that bdq operates a variation of your suggestion.

by offering a better price when something happens you can hoover too.
I can see it wouldn't work now. I was thinking about football where those moves don't occur without a suspend (or shouldn't occur). But even then there is potential for abuse.

I'm not convinced that you could hoover by altering an unmatched back bet to a higher price without delay. The same applies to lowering the price of an unmatched lay bet.

For example, in the situation that you submit an unmatched back bet of 2.1, if the correct price on that selection rises to 2.5, I don't see anyway that you could hoover anything by altering your unmatched bet to a higher price than 2.1 (of course if you didn't cancel or alter your bet you yourself would be hoovered).

If you could supply an example demonstrating that I'm wrong in reaching the conclusion above, I would be interested to read it.

With regard to soccer, as you alluded to, it would dramatically increase the probability of people beating the suspension if you could instantly alter an unmatched back bet to a lower price or an unmatched lay bet to a higher price.

As I previously mentioned, bdq uses a variation of your suggestion. Under their system, if you submit a bet into an in-play market at a price at which it would not be matched in part, or full, against a price currently available on that selection, your bet goes through to the market without the application of the standard in-play delay.

Bdq's system of bet submission is not flawless but it usually seems to work reasonably well. I have no objection to the alternative system that bf currently uses.
