Our verdict on each
BUX
BUX suits investors who want a Dutch broker for stocks and ETFs and accept a set fee per trade. It charges an account fee of €2.99 and a stock trade fee of €3.99, which is why the offer score sits at 2.1 and the overall score at 2.1.
moomoo

Pros and cons
BUX
Pros
- Fees follow a low-fee model: a stock trade fee of €3.99 per trade, an account fee of €2.99 and a currency exchange fee of 0.75%.
- Regulated by the Dutch Authority for the Financial Markets (AFM), with money held under the EU ICS up to EUR 20,000.
- Aimed at both beginners and experienced investors, with fractional shares and a mobile app listed in fractional shares and mobile app.
Cons
- The account fee of €2.99 applies on top of a stock trade fee of €3.99, so frequent trading costs add up.
- On stock trade fee it ranks 136 of 161, so cheaper share dealing sits elsewhere.
- Markets are limited to stocks and etfs, where CFI offers stocks, etfs and forex.
moomoo
Pros
- A stock trade costs $0 and an options contract costs $0, and the pricing model is commission-free.
- The account fee is $0, so an account left open costs nothing to hold.
- crypto, demo account and fractional shares covers fractional shares, a demo account, options, crypto and a mobile app, which suits smaller sums and practice trades.
Cons
- The market list is narrower than eToro's, which covers stocks, etfs and forex, while moomoo's own list is stocks, etfs and options.
- Support runs on email, phone and help centre only, so there is no live chat listed for questions raised during a trading session.
- Protection rests on a single scheme, SIPC up to USD 500,000, and SIPC names a single body, so there is no second cover behind it.
Who each suits
BUX
Who it suits
- Investors who want a regulated European broker covering stocks and etfs at a flat fee per trade.
- People who prefer mobile investing, since fractional shares and mobile app includes fractional shares and a mobile app.
- Readers who weigh protection first, since money sits under the EU ICS up to EUR 20,000 at a broker regulated by the Dutch Authority for the Financial Markets (AFM).
Who should look elsewhere
- Traders who want forex, contracts for difference or crypto, since CFI covers stocks, etfs and forex and BUX covers stocks and etfs.
- Share dealing fans after a free stock trade fee, since eToro lists $0 against the €3.99 here.
- Anyone put off by a standing charge, given the account fee of €2.99 where Vantage lists $0.
moomoo
Who it suits
- Investors who want shares, ETFs, options and crypto on one commission-free account, since stocks, etfs and options covers all four.
- Smaller-sum investors who want fractional shares and a demo account, both named in crypto, demo account and fractional shares.
- Readers comfortable with a US SIPC member arrangement, given SIPC up to USD 500,000 and SIPC member 69739.
Who should look elsewhere
- Anyone who wants forex, contracts for difference, metals or futures in the same account: eToro covers stocks, etfs and forex.
- Readers who want metals alongside shares, ETFs and crypto: Vantage covers forex, cfds and stocks, while moomoo's list is stocks, etfs and options.

Questions about each
BUX
How much does it cost to buy a share at BUX?+
A stock trade costs €3.99 per trade under a low-fee model, and a currency exchange fee of 0.75% applies on currency conversions. Because the trade fee is a flat amount rather than a percentage, the cost does not grow with the size of the order. A flat account fee of €2.99 also applies to the account.
Is there an account or inactivity fee?+
There is an account fee of €2.99, charged on the account regardless of how much it holds. That is a flat charge rather than a percentage, so it does not rise as the portfolio grows. BUX ranks 108 of 138 on this line, which places it towards the expensive end of the brands compared here.
moomoo
What does moomoo charge to trade stocks and options?+
On the commission-free account, the stock trade fee is $0 and the options contract fee is $0. The account fee is $0, so nothing is charged to keep the account open. Those figures are the whole cost side of the offer, and they apply to the same account rather than to a paid tier.
What does a commission-free account mean for the cost of a trade?+
The pricing model is commission-free, so a stock trade is charged at $0 rather than a percentage of the order, and an options contract at $0. Removing commission does not change the price at which an order is filled, so the buy and sell prices still matter as much as the fee line.
