Interactive Brokers

What is Interactive Brokers?

Interactive Brokers is a US multi-asset brokerage founded in 1978 by Thomas Peterffy and headquartered at 1 Pickwick Plaza, Greenwich, Connecticut. The parent company, Interactive Brokers Group, Inc., trades on NASDAQ under the ticker IBKR following its 2007 initial public offering. The group reports 4.75 million customer accounts and roughly 870 billion USD in client equity as of April 2026.

The firm operates through ten regulated subsidiaries spanning the United States, United Kingdom, Ireland, Canada, Australia, Singapore, Hong Kong, Japan, India, and Luxembourg. Each entity holds a separate license in its home jurisdiction, and client accounts are booked at the entity matching the trader's residency. The business model is direct market access, or routing client orders straight to exchange order books rather than internalizing them.

Founder Thomas Peterffy remains the largest shareholder, and the group's annual report (Form 10-K) is filed publicly with the US Securities and Exchange Commission. That filing covers ownership, audited financials, segment revenue, and risk factors, making the group one of the most financially transparent retail brokerages on the market.

Which regulators license Interactive Brokers?

Interactive Brokers discloses oversight by ten Tier-1 regulators, meaning bodies that combine a capital regime, segregation rules, a compensation scheme, and active enforcement. The US arm, Interactive Brokers LLC, is registered with the SEC (US Securities and Exchange Commission) under broker-dealer number 8-47257, with FINRA (Financial Industry Regulatory Authority) under CRD 36418, and with the NFA (National Futures Association) under member ID 0258600 for futures and retail forex.

The UK arm, Interactive Brokers (U.K.) Limited, holds FCA (Financial Conduct Authority) authorization under FRN 208159, showing as active registration on the FCA Register as of the scan date. UK retail clients are covered by the Financial Services Compensation Scheme up to 85,000 GBP in the event of broker insolvency.

The Australian entity holds an ASIC (Australian Securities and Investments Commission) Australian Financial Services Licence under AFSL 245574. Other group licenses include the Investment Industry Regulatory Organization of Canada under its successor body CIRO, the Monetary Authority of Singapore under Capital Markets Services Licence CMS100917, the Securities and Futures Commission of Hong Kong under AXY277, the Japan Financial Services Agency, and the Central Bank of Ireland under reference C423427. US clients are protected by SIPC coverage up to 500,000 USD (250,000 USD cash) plus an additional Lloyd's of London policy disclosed in the broker's regulatory filings.

Trading platforms

The firm offers four trading interfaces plus a developer toolkit, so traders pick the surface that matches their workflow rather than a single proprietary application.

Trader Workstation (TWS)

Trader Workstation, or TWS, is the flagship desktop client running on Windows, macOS, and Linux. It exposes around 100 order types, algorithmic execution presets, options analytics, and a customisable layout for advanced traders. TWS has won multiple platform awards from Barron's and Stocks & Commodities magazine.

IBKR Desktop and Web

IBKR Desktop is a lighter rewrite of TWS aimed at retail traders who find the legacy interface dense. IBKR WebTrader runs in a browser with no install, supporting the same global market routing through a simplified order ticket.

IBKR Mobile and GlobalTrader

IBKR Mobile mirrors the desktop feature set on iOS and Android, while IBKR GlobalTrader targets beginner mobile users with a stripped-down asset list. The mobile app holds an aggregate rating in the 4.5 to 4.7 band on the Apple App Store and Google Play as of the scan date.

API access

The broker exposes REST, WebSocket, FIX, Java, Python, and C++ APIs at no extra cost. Algorithmic traders and institutional desks connect order management systems directly into Interactive Brokers' order router. MetaTrader 4 and MetaTrader 5 (MT4 / MT5) and cTrader are not supported.

Account types

The broker offers multiple account structures, each booked at the regional subsidiary matching the client's residency.

Individual cash and margin accounts

Cash accounts settle trades fully funded, with no leverage. Margin accounts, or accounts that borrow against pledged securities, support intraday and overnight leverage subject to Regulation T in the US and ESMA rules in Europe.

IBKR Pro and IBKR Lite

US clients pick between IBKR Pro (tiered or fixed commissions, NBBO routing) and IBKR Lite (zero stock and ETF commissions, payment-for-order-flow routing). Pro is the default for active and professional traders.

Joint, trust, IRA, and entity accounts

Joint accounts, retirement accounts under the US Individual Retirement Arrangement framework, trusts, and entity accounts (LLC, partnership, corporation) are all supported. Family Office and Hedge Fund Master/Sub structures cover allocation workflows for institutional clients.

Demo (paper trading)

A paper trading account ships with every funded account at no extra cost and is unlimited in time and balance, letting traders test TWS strategies without capital risk.

Minimum deposit

Interactive Brokers removed its historical 10,000 USD minimum deposit in 2021. The current minimum is 0 USD for all standard retail account types across every regional entity. There is no minimum balance requirement after funding, and the broker also eliminated its previous 10 USD per month inactivity fee in July 2021.

Tradeable instruments

The broker advertises access to 150 markets in 34 countries across 27 currencies, one of the broadest instrument universes in retail brokerage.

• Forex: 105 currency pairs on the IDEALPRO interbank network
• Stocks: 90+ exchanges including NYSE, NASDAQ, LSE, Euronext, TSE, ASX, HKEX
• Options: equity, index, and FX options on 35+ exchanges
• Futures and futures options: 35+ exchanges including CME, ICE, Eurex, SGX
• Bonds: US Treasuries, corporates, municipals, and 1 million+ non-US bonds
• Funds: 48,000+ mutual funds, plus ETFs on every major exchange
• Crypto: spot trading via Paxos for US clients in selected states

Retail US forex is restricted to Eligible Contract Participants, or accounts with at least 10 million USD in assets, under NFA rules. Retail US forex on margin is therefore not offered to standard US individual clients; UK, EU, Canadian, Australian, and Asian entities offer retail spot forex within their local leverage caps.

Spread and commission structure

Pricing splits into spread cost and explicit commission, both disclosed on the broker's official site.

Forex spreads

The IDEALPRO interbank network publishes EUR/USD spreads, or the gap between bid and ask, starting from 0.1 pip, with a one-tenth of one basis point commission on trade value (minimum 2 USD per order). A pip is the standard unit of price movement in forex, equal to 0.0001 on most pairs.

Stocks and ETFs

IBKR Pro charges 0.005 USD per share with a 1 USD minimum on US stocks (tiered pricing lowers this for high-volume traders). IBKR Lite charges 0 USD on US stocks and ETFs. Non-US markets are priced per local exchange schedule.

Options and futures

US equity options run at 0.15 to 0.65 USD per contract depending on premium and volume. US futures contracts charge 0.25 to 0.85 USD per contract under the tiered schedule. Every fee schedule is published in full on the broker's pricing pages, with no marketing markdown.

Leverage and margin requirements

Leverage caps follow each subsidiary's local regulator rather than a single global setting.

• UK and EU retail forex: up to 1:30 on major pairs under ESMA / FCA rules
• Australian retail forex: up to 1:30 on majors under ASIC Product Intervention Order
• US ECP forex: up to 1:50 on majors under NFA rules
• Hong Kong, Singapore, India: up to 1:20 to 1:30 depending on pair class
• Professional and institutional clients: higher leverage subject to risk assessment

Stock margin runs at standard Regulation T 50% initial in the US, with portfolio margin available for accounts above 110,000 USD. The broker publishes its real-time margin requirement and maintenance margin per instrument inside TWS.

Deposit and withdrawal methods

Funding methods match the institutional positioning: bank rails dominate, with no credit card or e-wallet support.

• Bank wire (worldwide, T+1 to T+2 typical)
• ACH transfer (US clients, free, 4 business days first transfer)
• SEPA transfer (EU clients, free, T+1 typical)
• Faster Payments and BACS (UK clients, free, same-day typical)
• Check deposit (US clients, manual processing)
• Internal transfer (asset transfer in kind from another broker via ACATS)

The first withdrawal of each calendar month is free; subsequent wires carry a 10 USD fee for US dollar transfers, scaling for other currencies. Card and e-wallet funding is not supported across any subsidiary.

Fees beyond the spread

Several charges sit outside the headline commission table and are worth noting.

• Market data subscriptions: most non-US exchanges charge a monthly subscription (1 to 30 USD typical); US non-professional Level 1 quotes are bundled free
• Currency conversion: 0.2 basis points commission on FX conversion through IDEALPRO, minimum 2 USD per conversion
• Borrowing rates (margin interest): tiered, posted daily on the broker's pricing page; US dollar borrow benchmarked to the Fed Funds upper bound plus a spread
• Inactivity fee: 0 USD since July 2021
• Account closing or transfer-out (ACATS): 0 USD inbound, fee schedule applies for full-account outbound

Market data fees are a real consideration for casual traders covering multiple regions, since the subscriptions stack per exchange.

Mobile app and trading experience

The IBKR Mobile and IBKR GlobalTrader apps cover both ends of the trader spectrum.

IBKR Mobile carries the full TWS feature set onto iOS and Android, including conditional orders, options chains, and global market routing. Biometric login, push notifications for fills, and a built-in scanner for screening watchlists are standard.

IBKR GlobalTrader is the simplified counterpart launched in 2022, aimed at beginner cross-border investors. The app focuses on stocks and ETFs across 90+ exchanges with a single-tap order ticket. Aggregate ratings sit in the 4.5 to 4.7 band on both major app stores as of the scan date.

Customer support

Support runs 24 hours during the US trading week with phone, chat, and a ticketing system inside the Client Portal. Coverage languages include English, Mandarin, Cantonese, Japanese, Russian, French, German, Spanish, Italian, Portuguese, Polish, and Hungarian.

The broker's published service-level commitment is a first response within one business day for ticketed queries; phone wait times vary by region and time of day. User-aggregate ratings of the support channel sit lower than the product ratings, with the most common complaint pattern centered on response speed during US market open hours.

Who is Interactive Brokers best for?

The broker fits active and professional traders who need global market reach, transparent fees, and Tier-1 regulatory cover. Stock and options traders running multi-leg strategies on US and international markets get the deepest value, since the per-share or per-contract pricing scales down with volume and the platform covers 150 markets in 34 countries.

Retail forex traders inside the US do not get a standard product, since NFA rules restrict spot forex on margin to Eligible Contract Participants with 10 million USD in assets. UK, EU, Australian, and Asian retail traders do get full forex access at the local leverage cap.

Casual investors holding a handful of US stocks may find market data subscription stacking and the TWS learning curve heavier than needed. IBKR Lite or IBKR GlobalTrader address that segment, but a single-market discount broker can be simpler for that profile.
