There are now two ways for displaying trading sessions for the futures contracts and continuous futures from CME Group:
You can search for new high/low prices, use the Session Volume Profile, and carry out any technical analysis that was previously hindered by bars outside the RTH session. The feature is available to all users regardless of their plan and subscriptions.
Restrictions:
If you need daily candles with RTH data, try using 24h candles instead of daily.
