Two toggles control how much your data tabs show, so you can go from a wide overview to a tight focus and back.
All accounts. Switch between viewing a single account and all of them at once.
All contracts. Leave it on (the default) to see your full account across every contract. Turn it off to focus a tab on just the contract you are charting.
Both are remembered per browser, so the terminal comes back set up the way you left it.
Flatten follows what you are viewing
The Flatten button (which closes positions) follows the same scope as your view, so it never leaves something open behind your back. If you want to close just one contract instead, the per-row close does exactly that.
Deleting an account
Deleting an account clears its positions and orders out of the terminal, so you are not left with leftover positions updating P&L for an account that is gone. Deleted accounts also drop out of the journal's "all accounts" view, though their history is kept in a permanent audit log.
