"Close Only" mode means that new trades cannot be opened for a specific instrument at the moment, but existing positions can still be closed, if any are open.
This mode is typically activated during periods of market instability, when trading conditions become potentially risky or unpredictable — both for traders and for the Company. Such situations may include:
Unexpected events involving specific companies or countries
Global developments
Earnings reports or announcements that carry heightened market risk
As a precaution, the platform may temporarily restrict trading on certain assets to "Close Only" mode to help protect clients from excessive volatility.
