Void bets via api-ng horse racing (Dundalk, IE)

[RDFHDFFDDVG]

As part of a strategy we watch for a GB/IE horse race to go suspended, sp reconciled and in-play via a bot using api-ng (we're pretty local in terms of latency ~10ms and we have a good async pattern allowing timing to be relatively sound). If a desire donkey meets the criteria (form and SP range) then we submit a limit order bet.

Occasionally some of these lapse because the price never goes out to our desired back price which is fine.

On the 20th December one bet has me completely confused, it shows in bet history as "Voided"

20th December - Dundalk, IE - 18:15 Dundalk Crowne Plaza Hotel Of Dundalk Rated Race


The bet was submit successfully via the placeOrder action and matched:

IRE / Dund 20th Dec / 18:15 To Be Placed Beat The Ballot Back <snip> 20-Dec-13
18:23 K 2.04 23.00 2.04


However Sportinglife tells though that Beat The Ballot was withdrawn
WD (11) 1 Beat The Ballot (IRE) T Collins 4 10-0 J P O'Brien 10/3

Does this mean that Betfair had the information on runners via the API wrong (we only look for runners with "RunnerStatus" as "Active")?

In this instance it went in our favor, but can someone explain what happened here? Could this be an API fault, should RunnerStatus also included "WITHDRAWN"? I also scanned the rules and regulations and found this ". In the event of a late withdrawal, Betfair reserves the right to remove the runner after completion of the race. " Then does this mean the man on the ground (or SIS/PA feed betfair use was wrong)?


Just trying to understand..

If I understand your question correctly, this is something that happens quite often InRunning, and I don't really think it could be described as a fault.

For example this afternoon my API-NG Bot submitted and had matched a Place Bet on Lil Rockefeller in the 12:20 at Lingfield.

I happened to be watching both the Bot and the Race, and Lil Rockefeller had refused to enter the Stalls, but during inPlay I could see his lastMatchedPrice in the Win market go down to as low as 2.0, so presumably my Bot's Place market Bet got matched by someone else's Bot, but the 'matched' bet was later Voided ... it shows in my Bet History under 'voided' as:

GB / Ling 4th Jan / 12:20 To Be Placed Lil Rockerfeller Back 33024881026 04-Jan-14
12:25 C 1.15 29.06 1.17

So as I say, I don't think it could be described as a fault.

Lil Rockefeller was stood ther planted behind the stalls as the race went InPlay, so i don't think there'd have been time to mark him as 'WITHDRAWN' or anything else because presumably that would have meant suspending the betting while the race was InPlay.
