ISLAND, ARCA all orders cancelled at around 8:30 EST

Major clusterf.

 

What happened ?

 

All my orders before the open were cancelled for ISLAND and later ARCA. IB confirmed. This is incredibly rare but, wow.

 

Sorry to hear that ! Do you think that source was ISLAND & ARCA, or IB ? Sounds like IB.

 

Issues at exchanges, according to them at least. Surprised no-one else was alarmed by this on ET...

 

Sim traders don't get those alerts.

 

Thanks
