Hey GRULSTMRNN, thanks for the great post. This is great info and learning experience. I know exactly what you mean with the risk this recklessness (of their programs or people) created. A) Can you explain the type of order that was placed? Was this a market order or a limit order? If a limit order, and this is on margin, one's account can be liquidated in a spike like this and that is very bad when no other broker can confer this or there was no event happening (news etc like you said). B) What happened to your friend? did they complain to any regulatory body and what did the body say or did they get compensation or lost the claim? C) Has this sort of anomaly happened on IBKR on other pairs since this was reported? D) I also only see IDEALPRO in reports. Where exactly do you see the exchange info? Is this report on web portal or in TWS? Thanks,
