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.
Lightspeed Financial
Pros
- Regulated in the US by FINRA, with SIPC cover of SIPC up to USD 500,000
- Trades run across stocks, etfs and options in one account
- A demo account is available to practise before funding
Cons
- A $10,000 minimum deposit is far above the site median of €4.64
- An inactivity fee of $25 applies on dormant accounts
- Support runs on phone and help centre only
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.
Lightspeed Financial
Who it suits
- Experienced traders who already trade options and futures
- Day traders who keep a large cash balance
- Anyone who wants a single account across stocks, etfs and options
Who should look elsewhere
- New investors, since no beginner audience is listed
- Small savers put off by a $10,000 minimum deposit
- Anyone wanting a free stock trade, as eToro charges $0

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.
Lightspeed Financial
What does it cost to trade stocks at Lightspeed Financial?+
A stock trade costs $4.50. That sits well above the site median stock trade fee of €0, and above what the median-ranked broker in this field charges, so the cost only makes sense for high-volume trading.
What is the minimum deposit?+
You need a minimum deposit of $10,000 to open an account. That is far higher than the site median minimum deposit of €4.64, and it rules out the small-balance investor entirely.
