Missing befair matched bets

[FreeBaseMace]

Hi, had a strange thing happen. Yesterday and last night had 9 lay bets matched on different horse racing markets that ran today. They were a mixture of manual and automated bets. They were all showing at 6am but some time later they were all gone with no record of them on betfair. The only record I can find of them is in the betangel log. The log below is complete.

6/5/2023 23:55:12: [G_Auto 1] : £ 2.00 Lay bet placed on Grow Nasa Grow at 42. £ 1.17 matched at 42 £ 0.83 unmatched when it initially reached the market. Ref: 309948772329 ( Fill or kill bet with 300 seconds delay. Offsetting by 400% [A] with greening. )
6/6/2023 00:00:12: [G_Auto 1] : £ 1.11022302462516E-16 of unmatched bet (Ref:309948772329) was filled before remainder was killed.
6/6/2023 00:00:12: [G_Auto 1] : £ 0.23 Back bet placed on Grow Nasa Grow at 210. Entirely unmatched when it initially reached the market. Ref: 309948896924
6/6/2023 08:04:01: Guardian has detected that the market is suspended
6/6/2023 08:04:02: Guardian has detected that the market is now unsuspended
6/6/2023 09:06:06: Guardian has detected that the market is suspended


This matched bet has gone? Was showing in account at 6am. Nothing on betfair profit/loss. No greening. The race ran and the runner ran.....Any ideas?

It's close to zero but not zero. It's 0.000000000000111022302462516.

Bet on races at Leicester, Lingfield, and Southwell placed prior to mid morning were voided by BF

Thanks, and yes all voided. Cheers for the replies

It's a general type rounding error. It's why you never code '=0' and should always use a function for testing near zero. Both ends of the process are equally to blame, BF for sending it, BA for accepting it.
