You normally not even lose all your account balance because you keep the open margin in case of a margin call. That was of importance today.

Stop Z5 and Z4 now. They should have stopped themselves anyway due to the stop slider. They could have taken large profits today when margin was left on the account after the peak down. Here's one of my Z5 logs from this morning:

The day started with EUR 8,707 on the Z5 account, and ended with EUR 43,304. Inbetween there was a margin call, followed by an equity peak at 280,000 EUR - not visible in the log but according to FXCM TS. It was not a real profit because the trades could not be closed, and the entry prices were probably wrong.

The EUR dropped to 0.8 CHF after the announcement, causing a margin call of my account with two Z5 instances. Both Z5 and the broker closed all trades. The two Z5 systems then immediately opened several new long trades due to the low-volatility algorithms. Strangely, FXCM accepted the trades. The EUR went then further down, then up again, but FXCM refused to close the new trades - you can see the many close attempts in the log. They finally closed at 1,04, putting EUR 43K on the account.

This was of course a lucky outcome, often brokers reject all trades at extreme volatility peaks. It's quite possible that this was no good day for other Z5 users.

Currently FXCM seems not to accept any EUR/CHF trades.

We have to declare Z5 officially dead now. At least unless they'll place a new CHF cap.
