I have received message on my e-mail from [email protected] and there was the following:

We are sending you an email to inform that your equity has decreased below the minimum allowed amount on your account with login DEMXXXXXXXXXX. Your account has been blocked. All open positions have been merged and closed. You have the right to fund your trading account to reinstate the margin level back.

Trade(s) details:
Position 19302753, SELL 2000000 EUR/USD at 1.421855, trade date 01ST Apr 2011, 18:00:03 GMT
Position 19265429, SELL 5000000 GBP/USD at 1.6114, trade date 01ST Apr 2011, 18:00:03 GMT

Actually I don't understand at all how it could happen, because I had nice two orders:
-BUY 5.000M GBP/USD @ 1.60502, SL 1.59475 (103 pips), TP 1.63270 (277 pips) profit at the moment when system closed it was P/L: +64 pips
-BUY 2.000M EUR/USD @ 1.41941, SL 1.41380 (56 pips), TP 1.42450 (51 pips) profit at the moment when system closed it was P/L: +24 pips

What should I do know? I have already sent some e-mails to support, but I have got nothing in response.

This is an automatically generated email, which informs you that your positions were closed as a result of a Margin Cut action that happened following the disrespect of the weekend leverage (1:30).
Please read (https://www.dukascopy.com/swiss/english/ ... ts/margin/) to learn more about the Margin Requirements. Please mind that for contest accounts no hedging positions are opened. Instead, the existing positions get automatically closed.

The message is standard. You do not have to pay attention to the part about funding the account.
