comdirect vs flatex — which broker is better?

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%

Pros

• EUR 5.90 flat commission on German, US, Canadian and other foreign orders with no percentage component up to EUR 40,000 — a EUR 10,000 trade costs the same as a EUR 1,000 trade
• All ETF and fund savings plans execute at EUR 0.00 commission with over 5,000 plans available and no cap on the savings rate
• No custody fee, no account fee, no inactivity fee, and free incoming and outgoing depot transfers
• Genuine spot crypto in around 25 coins at 0.6%–0.7% all-in, held inside the regulated German bank rather than as an ETN wrapper
• Full German banking licence under BaFin and Bundesbank supervision, with an MDAX-listed parent (flatexDEGIRO SE, ticker FTK) publishing audited accounts and over EUR 100 billion in customer securities under custody
• Tax-simple in both markets it serves: automatic German Abgeltungsteuer withholding and automatic Austrian KESt settlement at 27.5% on flatex.at
• Free foreign-currency sub-accounts, so USD or CHF proceeds can be held rather than converted back at a spread every time
• Fast onboarding — flatex advertises a five-minute fully digital account opening, and no minimum deposit applies

Cons

• 0.00% p.a. credit interest on cash balances. Competitors pay 1%–1.75% on the settlement or call account, so an investor holding EUR 20,000 in cash gives up EUR 200–350 a year that never shows up in any fee table
• Currency conversion costs an absolute margin of USD 0.0040 per euro — roughly 0.35% — which is worse than Consorsbank's published USD 0.0030 and far worse than a multi-currency specialist
• No Eurex or US options and futures trading at all. Certificates, knock-outs and Société Générale CFDs are the only leveraged instruments on offer
• Real-time quotes are metered: 25 free per month plus 10 per executed order, then EUR 0.01 per query, and the professional flatex trader 2.0 platform costs EUR 15–39 a month on top
• The EUR 5.90 floor makes flatex expensive for small orders — a EUR 300 purchase pays about 2% in commission before venue costs, where a EUR 1 neobroker charges 0.3%
• Direct foreign market access is narrow: US, Canada, Euronext, Vienna, Zurich and Milan (sell only). There is no direct London, Tokyo, Hong Kong or Nordic access, and stock savings plans cost 1.00% of the rate
