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.
Interactive Brokers
Pros
- A stock trade costs $0 and the minimum deposit is $0, the pairing behind rank 1 of 161 on stock trade fees among the brokers tracked here.
- The account types listed cover isa, sipp and ira, so an ISA, SIPP, IRA, joint or corporate account all sit under a single provider.
- bonds, etfs and forex puts stocks, ETFs, bonds, funds, forex, options and futures on the same account, with a margin rate of 4.38% for geared positions.
Cons
- Support runs on help centre and community, so a phone line and live chat sit outside the offer.
- bonds, etfs and forex covers shares, ETFs, bonds, funds, forex, options and futures but leaves out crypto and CFDs, which eToro lists in stocks, etfs and forex.
- An options contract costs $0.65 against a stock trade at $0, so options strategies pay a visible premium per contract.
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.
Interactive Brokers
Who it suits
- Investors holding money across several wrappers, since the account types listed cover isa, sipp and ira.
- Traders who want options, futures, forex and bonds alongside shares on a single account, per bonds, etfs and forex.
- Anyone starting with a small balance: the minimum deposit is $0 and fractional shares appear in the feature list (fractional shares and mobile app).
Who should look elsewhere
- Anyone who trades crypto or CFDs, since bonds, etfs and forex leaves both out while eToro lists them in stocks, etfs and forex.
- Readers who want a stated entry figure as a signal of the provider's target size, since Vantage publishes $5 where this broker's minimum is $0.

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.
Interactive Brokers
What does it cost to trade shares?+
A stock trade is charged at $0 and the minimum deposit is $0, so opening an account and dealing in shares carry no charge. The money sits in derivatives and leverage instead, where an options contract costs $0.65 and the margin rate is listed at 4.38%.
Is my money protected?+
The regulatory list runs to SEC, FCA and SIPC, and investor protection is stated as SIPC up to USD 500,000. The UK entry is the FCA under licence 208159, while the US side names the SEC and the SIPC membership SIPC member 53615. The protection figure describes the scheme stated for the account and says nothing about how a trade performs.
