Trading Status

As a 24 x 7 x 365 exchange, the Bullish platform should ordinarily always be available.

From time to time there are, however, periods of platform-wide downtime for scheduled maintenance or updates. These will be communicated to participants in advance (contact Market Operations to subscribe for notifications).

Additionally, there may be reasons for individual instruments to be temporarily removed from trading.

The platform will communicate both of these situations through the TradingSessionStatus [h] message which is broadcast from Bullish.
