Our verdict on each
CapTrader
CapTrader suits experienced traders who want stocks, forex, CFDs, options, futures, crypto, bonds and funds under one roof with no account or inactivity fee. The catch is the entry size: a minimum deposit of $2,000 puts it out of reach for a small first account.
Interactive Brokers
Interactive Brokers suits investors who want a single account across ISA, SIPP, IRA, joint and corporate holdings, with stocks, bonds, funds, forex, options and futures behind it. It ranks 1 of 213 brands on minimum deposit at $0, and stock trades are charged at $0.

Pros and cons
CapTrader
Pros
- A single account covers stocks, etfs and forex, so instruments do not need splitting across brokers.
- Platform choice of Trader Workstation TWS, CapTrader Desktop and Trading App covers desktop terminals and mobile trading.
- Trading costs read plainly: $2 a stock trade and €2 an options contract.
Cons
- Minimum deposit of $2,000 ranks 197 of 213 on our data, against $0 at CFI and $5 at Vantage.
- Stock trade fee of $2 ranks 124 of 161, while eToro charges $0 a trade.
- Support runs on help centre only, with no phone or chat channel listed.
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
CapTrader
Who it suits
- Traders running a mixed book of stocks, etfs and forex rather than one narrow market.
- Anyone who dislikes dormant account charges, with an inactivity fee of $0.
- Desktop users who prefer the Trader Workstation TWS or CapTrader Desktop over a simple app.
Who should look elsewhere
- Small first-time accounts: CFI starts at $0 and Vantage at $5, well below CapTrader's $2,000.
- Cost-first stock buyers: eToro charges $0 a trade against CapTrader's $2.
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
CapTrader
What is the minimum deposit?+
The minimum deposit is $2,000, which is the main hurdle for a first account. On our data that places CapTrader at 197 of 213. CFI takes $0 and Vantage $5, so a smaller start is easy elsewhere.
Are there account or inactivity fees?+
Neither applies. The account fee is $0 and the inactivity fee is $0, so leaving money untouched does not trigger a charge. CapTrader ranks 1 of 138 on account fee and 1 of 56 on inactivity fee.
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.
