FX Brokerages Move To "Close Only" Ahead Of Monday Open

First at Mayzus:

Upcoming risk - Instruments moving to 'Close Only' mode

Due to the uncertainty surrounding the ongoing Greek debt negotiations, and ahead of a potential announcement over the weekend that could lead to high volatility on the market, please be informed that we have decided to decrease your risks by temporarily moving all Instruments to 'Close Only' mode, from 22:30 GMT+3 on Friday the 26th of June 2015, until 00:30 GMT+3 on Monday the 29th of June 2015, trading terminal time.

Please take this information into consideration whilst making your trading decisions.

If you have any further questions regarding this issue, then please feel free to contact your Personal Account Manager or our support department on support@mayzus.com.

... next FxPro:

With Greece’s uncertain future in the Eurozone continuing to dominate the headlines, we would like to inform you that we are doing everything in our power to reduce the risk of trading EUR pairs.

In order to provide a safeguard against a highly volatile market open, trading on EUR pairs may be subject to increased margin requirements.

This depends on the outcome of today’s decisive Eurogroup meeting, and how the situation in Greece unfolds over the rest of the weekend.

Please be advised that, depending on the severity of market conditions come Sunday night/Monday morning, we reserve the right to limit EUR trading to the closing of existing positions only.

We will, of course, inform you of the trading conditions that will apply to EUR pairs before market open.

... shortly, everywhere else.
