Pros and cons
Ally Bank
Pros
- A stock trade costs $0 and the account fee is $0, so holding a US portfolio costs nothing at the platform level.
- The inactivity fee is $0, and Ally ranks 1 on that measure among 56, so a dormant balance is not quietly drained.
- Regulated in the US by SEC, FINRA and FDIC, with investor protection recorded as SIPC up to USD 500,000 and an FDIC certificate of FDIC cert 57803.
Cons
- The automated portfolios take a management fee of 0% to 0.3% a year, so a free account is not the whole cost picture.
- Options carry $0.50 per contract, so the commission-free model in commission free does not reach derivative trading.
- Account types run to joint, ira and roth ira, with no wrapper for a tax-sheltered investor who is not saving through a retirement account.
S Broker
Pros
- An account fee of €0 and stock trades at €0.95 keep the running cost of the account low.
- Regulated in Germany by the Bundesanstalt fuer Finanzdienstleistungsaufsicht and the European Central Bank, with deposits covered by the EU investor compensation scheme.
- A single account covers stocks, etfs and funds.
Cons
- Stock trades cost €0.95 each, which adds up for anyone dealing often.
- The market list is stocks, etfs and funds, so forex, CFDs and crypto traders have to look elsewhere.
- Support runs on email, phone and help centre, with no live chat listed.
Who each suits
Ally Bank
Who it suits
- US savers who want commission-free share dealing, a minimum deposit of $0 and an account fee of $0.
- Retirement investors, since joint, ira and roth ira covers individual retirement accounts and joint accounts.
- People who would rather ring than email, since email, chat and phone includes phone, chat, email and a help centre.
Who should look elsewhere
- Traders after forex, contracts for difference or crypto, since stocks, etfs and options stops at the US list while stocks, etfs and forex goes further.
- Anyone who wants leveraged index exposure on the same account, where CFI covers stocks, etfs and forex and Ally does not.
S Broker
Who it suits
- Investors who want stocks, ETFs, funds and bonds in a single account with an account fee of €0.
- German residents who want a supervised German firm and phone support as well as email.
- Options traders who also hold stocks, funds or bonds and want a single account for all of it.
Who should look elsewhere
- eToro, if a stock trade fee of $0 matters more than a German account with funds and bonds on the platform.
- CFI, if forex, CFDs and crypto matter, since its markets of stocks, etfs and forex reach well past stocks, etfs and funds.
- Anyone who wants live chat support, since support runs on email, phone and help centre only.

Questions about each
Ally Bank
What does it cost to open a self-directed account and place a trade?+
Opening costs nothing beyond the deposit itself, and the minimum deposit is $0. Trading shares carries a fee of $0 and the account fee is $0, so a small starter order does not eat into the position. Options are the exception and are priced separately per contract.
Is there a charge if I leave the account empty?+
No. The inactivity fee is $0, which means an account you stop using carries no monthly drain on the balance. It matters most for anyone splitting cash between trading and holding, because a dormant account here does not quietly shave the value of what sits in it while a decision is pending.
S Broker
What does S Broker charge for a stock trade and for the account?+
Stock trades cost €0.95 and the account fee is €0, so holding the account costs nothing. Across the site the median stock trade fee is €0, which leaves S Broker a little dearer than the cheapest stock platforms but with no account charge to set against it.
Who regulates S Broker and what happens to the money in the account?+
The legal entity is S Broker AG & Co. KG, supervised by the Bundesanstalt fuer Finanzdienstleistungsaufsicht and the European Central Bank. Deposits sit under the EU investor compensation scheme, so a firm failure is covered within that scheme's stated limits rather than by the broker itself.
