Moomoo doesn’t charge commissions for its trades. However, there are some fees you might end up paying. They are based on the regulatory fee structure from the SEC and other authorities. These fees only apply when you sell, however. For example, when you sell a stock or an ETF, you might pay the following fees: SEC fee: 0.0000051 x the transaction amount for each order, with a minimum of 1 cent Trading activity fee: $0.000119 per share, with a minimum of 1 cent and a maximum of $5.95. If you buy ADRs, you might pay a custodian fee of between 1 cent and 5 cents per share, depending on the bank involved. Options also come with similar regulatory fees. You’ll also pay a contract fee of 65 cents per contract. In many cases, you might not notice these fees because they are relatively small, and they are often included as part of the final transaction. Aside from these fees, Moomoo charges zero platform fees. However, the app includes a disclaimer that charging zero platform fees is considered a promotion and may end at any point. If this happens, Moomoo would give 30-day notifications to relevant parties.
