Options Cost Math: $0 vs $0.65
Moomoo charges $0 per options contract. Fidelity charges $0.65. For casual options traders this difference is minor. For active traders, it compounds into real money fast.
| Monthly Volume | Moomoo Cost | Fidelity Cost | Annual Savings |
|---|---|---|---|
| 25 contracts/mo | $0 | $195/yr | $195/yr |
| 50 contracts/mo | $0 | $390/yr | $390/yr |
| 100 contracts/mo | $0 | $780/yr | $780/yr |
| 200 contracts/mo | $0 | $1,560/yr | $1,560/yr |
| 500 contracts/mo | $0 | $3,900/yr | $3,900/yr |
The breakeven point: If you trade fewer than 10 contracts per month, the $0.65 difference is negligible. If you trade 50+ contracts monthly, Moomoo's $0 fee becomes a meaningful cost advantage — and at 200+ contracts, it's the equivalent of a second brokerage account's annual fee.
Data Tools: Moomoo's Free Bundle vs Fidelity Active Trader Pro
Both platforms have solid tools — but they serve different trader profiles. Moomoo wins on free institutional data. Fidelity wins on research depth and retirement tools.
Moomoo
Fidelity (Active Trader Pro)
The Honest Take
If you're a data-driven active trader who watches order flow, dark pool activity, and unusual options sweeps — Moomoo's free bundle is genuinely hard to beat. If you're a long-term investor who wants deep research, analyst ratings, and retirement planning tools — Fidelity's research ecosystem is more comprehensive. Many serious investors use both: Moomoo for active trading and $0 options, Fidelity for IRA accounts, ZERO funds, and retirement planning.
Retirement & ZERO Funds: Fidelity Wins Outright
This is the clearest category win in the comparison. Moomoo has no IRA accounts, no robo-advisor, and no proprietary funds. Fidelity has all three — and they're among the best in the industry.
IRA Suite + 1% Match
- Traditional IRA
- Roth IRA + 1% match
- SEP IRA
- SIMPLE IRA
- Rollover IRA
Fidelity Go Robo-Advisor
- $0 fee under $25K
- Auto-rebalancing
- Tax-loss harvesting
- ETF-based portfolios
- No minimum to start
ZERO Expense Ratio Funds
- FZROX — 0% ER (Total Market)
- FZILX — 0% ER (International)
- FZIPX — 0% ER (Extended Market)
- No minimum investment
- Fidelity-exclusive funds
Moomoo has none of these. If you need an IRA, a robo-advisor, or zero-cost index funds, Fidelity is the only option between these two. The 1% IRA contribution match alone can add thousands of dollars over a 30-year investing horizon — and FZROX's 0% expense ratio means you pay literally nothing in annual fund fees.
Who Should Pick Which Platform?
Active day trader who reads order flow
→ Pick MoomooMoomoo's free 24-level order book, dark pool data, unusual options activity alerts, and $0 options contracts give active traders a data edge Fidelity's standard platform can't match. Fidelity's Active Trader Pro is solid, but it doesn't include dark pool tracking or unusual options flow — tools that cost $30–$100/month elsewhere. At 100 contracts/month, Moomoo also saves $780/year vs Fidelity's $0.65/contract fee.
Long-term investor building a retirement portfolio
→ Pick FidelityFidelity is the gold standard for long-term investing. Zero-expense-ratio index funds (FZROX at 0% ER vs Vanguard's 0.03%), a full IRA suite with a 1% contribution match on Roth IRAs, $0 Fidelity Go robo-advisor, fractional shares from $1, and 24/7 phone support. Moomoo has none of these. For a buy-and-hold investor building a retirement portfolio, Fidelity wins by a wide margin.
Options trader who trades 50+ contracts per month
→ Pick MoomooMoomoo charges $0 per options contract. Fidelity charges $0.65. At 100 contracts/month, that's $780/year in savings at Moomoo. At 200 contracts/month, $1,560/year. For high-frequency options traders, this fee difference compounds significantly — and Moomoo's unusual options activity scanner adds a data edge Fidelity's platform doesn't offer.
Investor who wants zero-cost index fund investing
→ Pick FidelityFidelity's ZERO funds — FZROX (Total Market), FZILX (International), FZIPX (Extended Market) — have a 0% expense ratio. That's literally free. Moomoo has no proprietary index funds. For passive investors who want the lowest possible cost on index fund exposure, Fidelity's ZERO funds are unbeatable.
Trader who tracks international markets (HK, SG, AU)
→ Pick MoomooMoomoo supports trading in US, Hong Kong, Singapore, and Australian markets from a single account. Fidelity is US-only for retail accounts. For diaspora investors or anyone who wants direct access to Hang Seng-listed stocks (Tencent, Alibaba H-shares, Meituan) without opening a separate international brokerage, Moomoo is the only option between these two.
Retirement-focused investor who wants an IRA match
→ Pick FidelityFidelity offers a 1% match on Roth IRA contributions — free money on top of your retirement savings. Moomoo has no IRA product at all. For anyone building a tax-advantaged retirement account, Fidelity is the only option between these two. The 1% match alone can add thousands of dollars over a 30-year investing horizon.
New investor who wants branch access and phone support
→ Pick FidelityFidelity has 200+ branches nationwide and 24/7 phone support. Moomoo is online-only with chat and email support. For investors who want to walk into a branch, speak to a human advisor, or call at 2 AM with an urgent question, Fidelity's support infrastructure is among the best in retail brokerage.
Trader who wants a paper trading simulator
→ Pick MoomooMoomoo includes a paper trading simulator with full L2 data — you can practice reading order flow and testing strategies without risking real money. Fidelity has no paper trading feature. For new traders who want to practice before going live, Moomoo's paper trading environment is a genuine advantage.
Final Verdict: Moomoo vs Fidelity 2026
Moomoo wins for active traders. $0 options contracts (saves $780+/year at 100 contracts/month vs Fidelity), free 24-level order book, dark pool data, unusual options activity alerts, 4 AM pre-market, and a paper trading simulator with full L2 data.

ZERO-expense-ratio index funds (FZROX at 0% ER), full IRA suite with a 1% contribution match, $0 Fidelity Go robo-advisor, fractional shares from $1, 200+ branches, and 24/7 phone support.
