Frequently asked
- What is IBKR's margin rate?
- IBKR Pro USD margin runs 5.83% – 6.83% on a tiered basis as of May 7, 2026 — the lowest in retail brokerage. Lite runs ~2.5 percentage points higher.
- Does Interactive Brokers offer 24-hour trading?
- Yes. IBKR supports overnight trading on 10,000+ US stocks and ETFs from 8 p.m. to 3:50 a.m. ET via the IBEOS and Blue Ocean ATSs — by far the broadest 24-hour list in the industry.
- IBKR Lite vs. IBKR Pro — which should I pick?
- Lite is US-only, $0 commission, uses PFOF, has 7 a.m. ET extended-hours start, and ~2.5 pp higher margin. Pro is global, tiered or fixed pricing, no PFOF, SmartRouting across 90+ venues, 4 a.m. extended-hours start, and the lowest margin rates in retail. Pick Pro if you use margin, trade actively, or want best execution.
- Does IBKR support futures and forex?
- Yes — both. Futures and futures options on 35+ exchanges including CME, CBOT, NYMEX, COMEX, Eurex, HKFE, SGX, OSE, ASX, and NSE. Forex via IdealPro institutional ECN on 26 currencies with ~1/10 pip spreads on majors.
- Can beginners use IBKR?
- Technically yes — $0 account minimum, Lite tier is commission-free, and Client Portal is approachable. But TWS density intimidates many novices; if you primarily want a polished app for occasional investing, Fidelity or Robinhood is a softer landing.
- Does IBKR offer crypto?
- Yes — 11 coins (BTC, ETH, LTC, BCH, SOL, ADA, XRP, DOGE, AVAX, LINK, SUI) via Paxos Trust or Zero Hash. Commission is a transparent 0.12–0.18% of trade value with no spread markup. Wallet transfers to external addresses are supported.
- What's IBKR's API capability?
- TWS API (Java, C++, Python, C#, VB, ActiveX, DDE), FIX CTCI, and the modern Client Portal Web API (REST + WebSocket). Paper trading with $1M simulated funds is identical to live. No competitor matches this breadth in retail.
Notes
Broadest OTC access including pink/grey/foreign. Best short inventory for small caps.
