Interactive Brokers vs OANDA

Detailed Analysis

Interactive Brokers and OANDA are both reviewed on PipsPal. This side-by-side looks at how they compare across the four factors that actually affect trading outcomes: spreads and trading costs, regulation and safety, platform choice, and minimum deposit requirements.

Spreads & Trading Costs

Independently measured, Interactive Brokers averages 0.65 pips all-in on EUR/USD against OANDA's 0.98. That makes Interactive Brokers the cheaper of the two by 0.33 pips. These are spread plus commission on the account we measure, not advertised minimums — a broker quoting 0.0 pips with a commission can cost more than one quoting a wider spread with none.

Interactive Brokers offers From 0.2 pips, while OANDA offers From 0.1 pips. Both use standard-account pricing with costs built into the spread rather than separate commissions. Direct spread comparison on EUR/USD during liquid sessions is the cleanest like-for-like measure — the numbers above reflect typical conditions, not minimum advertised. During news releases or low-liquidity periods, spreads widen on both, and the relative difference may narrow or flip.

Regulation & Safety

Interactive Brokers is regulated by CFTC, FCA, SEC. OANDA holds licences under CFTC, NFA, FCA, ASIC. OANDA's regulatory footprint is noticeably broader, which matters most for traders who want jurisdictional optionality or are based in regions where one of these regulators operates directly. Broader tier-1 coverage typically means stronger compensation schemes, more rigorous capital requirements, and more established complaint resolution pathways.

Trading Platforms

Interactive Brokers supports Trader Workstation, WebTrader, Mobile. OANDA supports OANDA Platform, MetaTrader 4, TradingView. The platform choice here is mostly about fit with your existing workflow. If you already use one of the listed platforms at another broker, switching to the one that supports your platform avoids re-learning. Algorithmic and Expert Advisor traders should verify that their specific strategy is compatible with each broker's platform version and hosting environment before committing.

Minimum Deposit

Interactive Brokers requires a $0 minimum deposit, while OANDA requires $0. Both brokers allow testing the platform with any deposit amount, which is useful for verifying execution quality before committing significant capital. Don't confuse minimum deposit with recommended starting capital — trading with $50 creates position-sizing constraints that affect risk management regardless of broker. Plan your starting capital based on your strategy's drawdown tolerance, not the broker's minimum.
