LAY-SP not working as expected

[bolpx001]

Hi All, I have a bot which places about 5 LAY-SP bets on different horses in different races Occasionally the bet is not matched but becomes lapsed.
the most recent one was as follows:
Market IE / Tipperary 29th Jun / 17:10 5f Listed
Selection The Antarctic
Bid type Lay
Bet ID 272678833341
Bet placed 29/06/2022 11:01
Persistence P
Odds req. 1.7
Stake (€) 10.01
Liability (€) 7.01
Avg. odds matched Unmatched
Profit/Loss (€) -
My question is why did it lapse, my understanding is it should have been settled at BSP What am I missing
best regards - Paul

The minimum liability for an SP lay bet is £10/€10. This also applies to keep bets. If the liability is less than £10/€10 the bet will lapse instead of being matched at SP.

Hi,

I am not familiar with SP betting but I suspect it is because your liability is less than £10.

Backers stake (what you win) should be something like £14.29 for a loss to you of £10.00
