# Stream wallet fills

Subscribe to `userFills` with a wallet filter. Persist each cursor and trade identifier after processing. Use `userFillsByTime` to recover events if replay cannot satisfy the cursor.

## Cursor rule
Advance a durable cursor only after downstream storage succeeds. Treat a gap, correction, or finality change as a reason to backfill and reconcile.
