duplicate bet - how to do the timing with fill or kill and rearming delay?

[pj007]

Hi

I'm using simulation mode to test a strategy and I've had an order fire before the 'fully matched' order information comes through, generating a duplicate bet. Any words of wisdom would be welcome.

Trigger:
- unlimited triggers, 30 seconds before rearming
- fill or kill bet with 360 seconds delay
Conditions:
- unmatched bets on the current selection = 0
- available lay liability > 0.5 (starts with 100)

The trade above took all of the available liability (100). I would have thought that I had appropriate delays in place to be able to get confirmation of a previous trade and its liability information

My questions:
How does the last order trigger before the unmatched order is filled?
Why is the next order timed exactly to the second that the previous order ends, on every occurrence? (I've set a 30 second rearming delay)

The same has just happened again while I was watching

stake 0.89 was filled, unmatched bet for 36.15 then sat in unmatched window, then when the price moved it filled twice.

8/03/2025 15:04:08: [G_Auto 1] : Store Value for Rasmus Neergaard-Petersen: available_liability = 100 - 2.393 = 97.607
8/03/2025 15:04:09: [G_Auto 1] : $ 36.15 Lay bet placed on Rasmus Neergaard-Petersen at 3.7. Fully matched at 3.7. Ref: 10074 ( Fill or kill bet with 360 seconds delay. )
8/03/2025 15:04:09: [G_Auto 1] : $ 36.15 of unmatched bet (Ref:10067) was filled before remainder was killed.
8/03/2025 15:04:14: [G_Auto 1] : Store Value for Rasmus Neergaard-Petersen: available_liability = 100 - 197.603 = -97.603

Any suggestions welcome to get the timing right. I'm stumped

You could try these :

- Increase rearming time ;

- Adjust your refreshing time - ensure if you have a lot of markets on Guardian rules could trigger properly on all of them ;

- Include - 'Fill or Kill Bet Time condition' ;

Great! Thank you.
I've added the Fill or Kill condition. That sounds like the missing one. Just saw an unmatched trade get matched without a duplicate.

Can I check...?
I'm guessing that the rearm is after the rule triggers, not after the bet fills or unmatched bet fills. Is that correct? That's where my thinking was wrong.
Does any internet delay or interruption between my computer and the server have a role with bet input & output getting out of sync? e.g. If so, how do I mitigate that?

Rearming is that interval which .baf file checking if all conditions are executed to trigger ; Triggering is that action of .baf file when all conditions are executed.
