Managing and deleting journal data
The Danger Zone at the bottom of Journal → Manage Data has one button: Delete all trade data. Here is exactly what it removes, what it keeps, and why most of what it deletes comes back on its own.
What gets deleted, what survives
Confirming the dialog removes the journal's derived data: trades, the fills behind them, and every import batch. The confirmation toast reports the counts, e.g. Deleted 412 trades, 1,038 fills.
Three things are deliberately kept: your notes (per-trade and daily), your image attachments, and your strategies. Those are things you wrote — the journal will not destroy your own work to reset its arithmetic.
Why mirrored trades come back
The journal is a materialized view over fills. The copier keeps its own event log of every fill it has ever processed, and journal trades are just that log, paired into positions and summed. Deleting the journal's copy does not touch the log — so on the next journal page load, mirroring runs again and rebuilds every mirrored trade from scratch.
That makes Delete all trade data a safe repair tool for mirrored data. Suspect the pairing went wrong, or want a clean recompute from first principles? Delete and reload; the result is the same trades, rebuilt.
What is truly gone
Imported trades have no event log behind them — the CSV you uploaded was their only source, and the batch record is deleted with everything else. After a reset, imported history is gone unless you still have the files and import them again.
One subtlety on notes: per-trade notes, tags, strategy assignments, and planned risk live on the trade rows, and the rebuilt mirrored trades are new rows. A full reset therefore resets that per-trade annotation; daily notes and attachments are keyed to the day, not the trade, and survive intact.
Quick answers
Will my copier trades disappear permanently?
No. Mirrored trades rebuild from the copier's event log on the next page load. Only imported data is permanently removed.
Can I delete just one bad import instead of everything?
Yes. Each upload is a batch on the Import History card with its own delete button — that removes only that batch's trades.
Are my notes and screenshots deleted?
Daily notes, attachments, and strategies are kept. Per-trade annotations are reset along with the trade rows they were attached to.
