Strengths and weaknesses side by side
Editorial assessment based on the recorded data.
comdirect
One of Germany's most complete online brokers — every product, every platform, and a price list to match.
Pros
- The broadest product range of the three German incumbents: shares, ETFs, funds, bonds, certificates, warrants, CFDs and direct Eurex options and futures in one depot
- Excellent platform stack — ProTrader for real-time multi-monitor trading, O&F-Trader with a margin simulator, CFD Trader with a free demo, plus a documented REST API and stock3, TraderFox and Quant4you integrations
- Cash sits behind Commerzbank AG: statutory EdB cover of EUR 100,000 plus the voluntary BdB Einlagensicherungsfonds protecting private individuals up to EUR 3 million, with direct ECB supervision as a significant institution
- Custody is now free for depots opened from 15 July 2026, and the second depot has always been free
- Cheap Eurex derivatives pricing: EUR 1.50 per single-stock option contract and EUR 1.50 for the MicroDAX future, each with a EUR 9.90 execution minimum
- Fully tax-simple for German residents — automatic Abgeltungsteuer withholding, Freistellungsauftrag, loss-offset pots and free annual tax certificates
- A EUR 1.00 Pure Depot exists for investors who only need gettex and savings plans, and a 15% Viel-Trader discount rewards 125+ trades per half-year
Cons
- Standard commissions are among the highest in the market: EUR 4.90 plus 0.25% of order value, minimum EUR 9.90 and maximum EUR 59.90, plus a EUR 2.50 venue fee — roughly four times what flatex charges on a EUR 10,000 order
- Savings plans cost 1.50% of the amount invested per execution. On a EUR 500 monthly ETF plan that is EUR 7.50 a month, or EUR 90 a year, where Consorsbank and flatex both charge zero
- Customer service is the standout failure: 1.4 out of 5 on Trustpilot across 4,117 reviews, dominated by complaints about extremely long telephone hold times and unhelpful responses, despite the advertised 24/7 desk
- The advertised EUR 3.90 per trade applies only to new depot customers for 36 months, after which the full tariff returns — the headline number is not the price you end up paying
- The cheap Pure Depot is heavily restricted: gettex only, no off-exchange trading, no derivatives, no IPOs, no ProTrader, no securities credit, no joint or second depot
- No spot cryptocurrency and no wallet — exposure is limited to crypto certificates and ETNs, and foreign trades settle at Commerzbank reference rates rather than a published percentage markup; comdirect's own cost disclosure estimates the conversion at 1%
Best for
Fio banka
A privately owned Czech bank with Prague, US and XETRA access and a DIP account — but currency conversion at its own rates with no published margin.
Pros
- XETRA orders cost EUR 3.95 up to an order value of EUR 1,400 (EUR 1.98 up to EUR 500 on a DIP account), with German trading from 08:00 to 22:00
- One account for the Prague Stock Exchange, RM-SYSTÉM, NYSE, NASDAQ and XETRA, plus bonds, certificates, warrants and Fio's own funds
- Offers the Czech DIP: up to CZK 48,000 a year deductible, no fees for opening or running it and no portfolio-based fees
- Fio banka, a.s. is a Czech bank and securities dealer licensed by the ČNB according to its legal notice; cash falls under deposit insurance up to EUR 100,000 and securities under the Garanční fond (90% up to EUR 20,000)
- No minimum deposit and no safekeeping fee on listed shares and ETFs held through Fio's omnibus accounts
- Free 30-day e-Broker demo and free Škola investování seminars (89 seminars in 19 cities in 2025)
- Branches across the Czech Republic and Slovakia, and a phone dealing desk until 22:00 on weekdays
- Loans for trading in CZK, EUR and USD and short selling on the Prague Stock Exchange
Cons
- US orders cost a flat USD 7.95, or USD 9.95 above 100 shares — expensive for small US purchases
- Currency conversion runs at Fio's own rates, shown only in e-Broker; the bank's FX rate sheet sat roughly 3% either side of the reference rate on 2 November 2026, with better rates only above USD 10,000 between 09:00 and 16:30
- Dividends and other cash payments credited from instruments in Fio's own register cost 0.20% plus VAT
- We found no options, fractional shares or crypto, and futures trading has ended per Fio's Slovak price list; short selling in the US is suspended
- Serves the Czech Republic and Slovakia only as far as we could find, with support in Czech and Slovak
- Fio Smartbroker rates 3.7 on the Czech App Store and 3.5 on Google Play (2 November 2026), and Fio funds cannot yet be bought in the app
