Many Europeans end up with two or more brokers — a local bank app, Trading 212 or Revolut for ETFs, IBKR for scale, maybe Binance for crypto. That works until statements disagree and you lose the plot.
Common messes
| Problem | What it looks like | Fix |
|---|---|---|
| Duplicate symbols | VWCE vs VWCE.DE vs ISIN-only row | Match to one instrument |
| Missing cost basis | P/L blank or “—” | Treat P/L as incomplete; don’t invent numbers |
| Stale snapshots | Old Excel overwrites fresher sync | One source of truth per account |
| Cash drift | Leftover EUR in three apps | Include cash in allocation reviews |
Hygiene checklist
- One source of truth per account — prefer live sync when available; otherwise upload the latest statement and retire older files.
- Reconcile symbols — resolve pending matches so the same fund isn’t listed twice under different names.
- Separate cash from “stablecoins as positions” if that matches how you think about risk.
- Review allocation monthly, not every tick — rebalance with new money when possible.
How InvestPane helps
Connect or import each broker, then use holdings and stats to see allocation and gaps in one place. Product setup guides live in Docs; this Learn section stays focused on investing concepts.
Key takeaways
- Multi-broker is fine; unreconciled data is not.
- Prefer sync over stale files for accounts that support it.
- Missing cost basis is a data issue — don’t fake P/L.
