Import your comdirect portfolio into Quantic
comdirect is a bank as well as a broker, so its exports carry more than trades. Quantic maps the columns it needs and ignores the rest.
A Direktbank keeps your securities account and your current account in one relationship, which is convenient and makes for a messier export: a downloaded statement can mix trades, dividends, fees and ordinary cash movements in one file. Quantic does not mind. You tell it which columns carry the date, the instrument, the quantity and the price, and rows that cannot be read as a trade are reported as skipped rather than guessed at.
Like every German broker, comdirect withholds Kapitalertragsteuer at source and reports it, so the number worth importing is not what you owe — it is what you actually received, and what it cost you to get there. Quantic keeps gross, withholding and net as three separate figures rather than one, because a dividend that arrived net of 26.375% and one that arrived whole are different facts about your income.
How to import it
-
1
In comdirect, open your securities transactions and export them as CSV.
-
2
Export your income statement separately if dividends are not in the same file.
-
3
In Quantic, open Movements and drop the file in.
-
4
Map the columns once and save the mapping. A statement with extra cash rows still works — unmappable rows are listed, not invented.
German bank exports often put account and period details above the header row, and Quantic reads the first row it finds as the header. If the column list looks like metadata rather than column names, delete those lines and upload again. We have not validated a real comdirect export yet, so this is the failure to expect — and the import screen will offer to send us the file if it will not read at all.
Key terms
- Gross vs. net
- Gross is the dividend before tax; net is what actually lands after withholding tax. Quantic tracks both.
- Withholding tax
- When you own a foreign stock, the company's home country usually skims a percentage off each dividend before it reaches you — say 15% on US shares. Quantic estimates this from where each holding is based and your tax residence, so your income reflects what actually arrives. It's the tax withheld at source only — not any tax your own country adds, nor amounts you can often reclaim or credit back under a tax treaty.
- Cost basis (average cost)
- What you actually paid for the shares you hold, per share — the money you put in, including the commission, spread across your shares. Buying more at a different price moves it; selling doesn't, because selling doesn't change what the shares you kept cost you. It's the baseline your gain, your yield on cost and any future tax calculation are measured against.
- ISIN
- The twelve-character code that identifies a security worldwide, regardless of which exchange it trades on or what ticker it uses there. Unlike a ticker, it doesn't change when a company renames itself — which is why an import identifies your holdings by ISIN where the file carries one, so a renamed company keeps its dividend history instead of splitting into two positions.
