Anyone suffered auto-liquidation of positions on IB due to portfolio value bug today?

According to this reddit thread, some IBKR customers' portfolio were down by 100% temporarily due to a bug. The biggest nightmare is that the system went into auto-liquidation mode if it mistakenly believes that margin was seriously impacted due to the portfolio "crash".

Did anyone experience such a nightmare due to the bug?

I personally did not and have so far had good experience with IB platform. After today, I'm sure many customers will be left disappointed and worried even.

 
It does seem to me that something is wrong with a release of the backend that they made on Tuesday. They still haven't been able to reinstate a paper trading account for me.
 
You monitor your in account every hour, even when your principle markets are closed?
I trade fully automatic, so don't worry: I do not sit 24 hours per day in front of the computer screen. My trading currently involves instruments in Korea, Singapore, Germany and the US. So yes, it is almost 24 hours per day operational.
As a monitoring tool do I download the account values every hour and store it in a spreadsheet (e.g. account value, maintenance margin). I didn't see anything special in this spreadsheet.

It is dangerous to trade automatic if the data is unreliable. IBKR market data is not reliable enough to give one the confidence to trade automatic. Just look at what happened today. If portfolio suddenly drops so much, all your cut-losses will be hit.

The impact will depend strongly on what safety valves have been built into the system. And on how the system responds to changes in the account value. In other words: how the system has been implemented. I wouldn't immediately judge all automated trading systems.

That makes sense.
 
I know you were specifically asking for people who had problems, but maybe to help to reassure you, I held positions overnight in 8 different underlyings (US equity options) and I was not liquidated.

However, I do see a single bulletin that appears to be related:
To all traders:

Fri Mar 9 02:47:15 2018 EST

The issue with the displaying of positions that affected some customers has been resolved. We apologize for the inconvenience.

Perhaps it was a display only bug.

EDIT TO ADD:
Just received another bulletin:

To all traders:

Fri Mar 9 09:35:33 2018 EST

Further to our earlier message, the position display issue was resolved. In the meantime if you have received a message alert regarding account valuation change, please check from the trading platform to confirm the account status. We would also advise you to check your open orders to see if you would need to replace any of them if in case they were cancelled. If you have any further questions, please let us know. Once again, we apologize for the issue.

From this one it sounds like it could be more than merely display as they are admitting orders may have been cancelled. Hopefully it's not more than that.

Every broker has problems, but why would anyone suffer everything that happens at IB? Are they really that good the other 99% of the time?
