The Market-data, News and OMS APIs are unavailable:
1AM every night for 5 mins.
7AM every sunday for 5 - 10 mins.
Between 10PM and 11PM for 5 - 10 mins for releases. These happen once a week on average.
To minimize the impact on your applications, we recommend storing data like prices after 7PM on trading days.
We also recommend to implement a circuit breaker and increase the time between retries till the API is available again.
