Offset Bet Not Placed

[BetScalper]

Hi,

Why did the offset not get placed ?

19/04/2019 15:03:42: [G_Auto] : £ 2.00 Lay bet placed on 6. Canny Raquel at 4.4. Entirely unmatched when it initially reached the market. Ref: 161722708495 ( Fill or kill bet with 300 seconds delay. Offsetting by 4 ticks. Stop at 2 ticks. Place stop at 4 ticks )
19/04/2019 15:03:44: [G_Auto] : £ 1.7 of unmatched bet (Ref:161722708495) was filled before remainder was killed. Position Closed therefore no offset/stop required.

This left me with potential exposure so i manually greened up

Thanks,

[Dallas]

The log is saying that the position was closed with 30p still to be matched so there was no offset bet to place

Were there any other entries before or after those in your log?
Or do you have the details on matched bets?

[BetScalper]

No other entries in the log file.

[Dallas]

How about your matched bets?

Was there a total of £2 of lay bets matched

[BetScalper]

I will have to wait until it happens again as i deleted the market from guardian.

[Dallas]

OK, if it does grab a screenshot of your matched bets tab to and that should piece together what happened

[BetScalper]

Will do. Thanks Dallas

Happened again Dallas. Hornblower is missing another offset.

Do you have the log from it to?

Edit; just seen the logs now been added

[BetScalper]

Posted at the top of the screenshots.

If you look at the time difference between of those entries there is a 10 second time difference

19/04/2019 22:04:42: [G_Auto] : £ 2.00 Lay bet placed on 5. Hornblower at 4.3. Entirely unmatched when it initially reached the market. Ref: 161781531553 ( Fill or kill bet with 999 seconds delay. Offsetting by 2 ticks. )
19/04/2019 22:04:52: [G_Auto] : £ 2 unmatched bet (Ref:161781531553) was killed.

When Bet Angel makes a request it gives Betfair 10 seconds to respond after that it has to try and determine whether the bet was actually killed or not based on the information it is given.
In this case, BA is unaware its been matched and instead is believing its been killed so no offset has been placed

When Betfair fail to respond in a timely manner it usually means they are having API issues at the time.

I can see your using streaming from your screenshots so it might be worth trying polling to see if that improves it

Thanks Dallas,

Is there a trigger i could build to make sure it doesn't occur or ?

[Dallas]

If you're just placing the 1 bet with offset each selection, you could add the following;

'Set/modify signal rule and set a signal on the selection named 'X'
with the following condition
'Amount of matched bets condition' back bets matched is equal to £2

'Close trade on selection with greening' with the following conditions
'Amount of matched bets condition' lay bets are equal to £0 (you could maybe add another for back bets equal to £2 but I'd prob stick to just the lay condition to start with)

'Signal changed condition'
Signal name 'X' changed between 10 secs and 11 secs (use whatever time you want here)

That will basically tell the close trade rule to trigger 10 secs after the back was matched if the lay bets are still £0

Depending on exactly how your strategy works you may need to change bits of that but that's the general approach I'd use from what I can see your doing

Hi,

Seems to be happening allot today. Had 4 offsets not placed on greyhounds.

Turned off streaming but it's still occurring.
