Pros and cons
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.
tastyfx
Pros
- No minimum to start, a minimum deposit of $0 against a site median of €4.64
- The pricing model is commission-free, so you pay for the spread inside the trade rather than a ticket fee
- No inactivity charge, at $0 and first in the site ranking on inactivity fee, 1 of 56
Cons
- The market list is limited to forex, so a share or bond holding is not available here
- Wire withdrawals cost, at Deposits free, $15 wire withdrawal fee
- Retail currency trading runs to a typical loss rate of 72.13% across the brokers compared, and leverage of 50:1 magnifies it
Who each suits
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.
tastyfx
Who it suits
- Beginners opening a first currency account in the US
- Traders who want to practise on a demo before risking money
- Anyone who wants a commission-free structure rather than a per-trade ticket
Who should look elsewhere
- Anyone who wants shares, ETFs or bonds, since forex is the only market offered
- Retirement savers who need a wider account range than corporate and ira
- People who withdraw by wire often, because Deposits free, $15 wire withdrawal fee applies

Questions about each
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.
tastyfx
What is the minimum deposit at tastyfx?+
The minimum deposit is $0, so you can fund an account from a small starting amount rather than waiting for a larger balance. That places tastyfx first in the site ranking on minimum deposit, 1 of 213, against a site median of €4.64.
Does tastyfx charge any commission on trades?+
The pricing model is commission-free, so there is no separate ticket fee per trade. The cost of a currency trade is built into the spread you trade through. The only market on offer is forex, so this structure applies to currency pairs.
