Interactive Brokers (IBKR) and tastytrade sit at the top of almost every active trader’s shortlist — for completely different reasons. Interactive Brokers is a global, multi-asset execution powerhouse built around institutional-style order routing, low margin rates, and access to 150+ market centers across stocks, options, futures, forex, and bonds. tastytrade is a purpose-built US options and futures platform designed from the ground up for multi-leg options sellers, visual payoff curve analysis, and capped per-leg options commissions.

Real Trade Cost Math: Where Each Broker Wins
Headline per-contract numbers hide an important crossover point on options trades. Because tastytrade charges $1.00 per contract on the open (capped at $10 per leg) and $0.00 on the close, while IBKR Pro charges $0.65 per contract on both the open and the close ($1.00 order minimum), the cheaper broker depends entirely on how many contracts you trade per leg.
Scenario 1: Single-Contract Options Round Trip (1 Contract Open + Close)
- Interactive Brokers Pro:
$1.00to open (minimum order fee) +$1.00to close = $2.00 round-trip commission - tastytrade:
$1.00to open +$0.00to close = $1.00 round-trip commission - Winner at 1 contract: tastytrade (because IBKR’s $1.00 single-order minimum applies to 1-contract orders on the Fixed plan).
Scenario 2: Mid-Size Options Trade (5 Contracts Per Leg, Round Trip)
- Interactive Brokers Pro:
5 × $0.65 = $3.25to open +$3.25to close = $6.50 round-trip commission - tastytrade:
5 × $1.00 = $5.00to open +$0.00to close = $5.00 round-trip commission - Winner at 5 contracts: tastytrade (
$5.00vs.$6.50). Note: on IBKR’s Tiered plan, liquidity-adding limit orders on certain exchanges can receive exchange rebates that narrow or flip this gap.
Scenario 3: Large Options Position (20 Contracts Per Leg, Round Trip)
- Interactive Brokers Pro:
20 × $0.65 = $13.00to open +$13.00to close = $26.00 round-trip commission - tastytrade: Capped at $10.00 to open + $0.00 to close = $10.00 round-trip commission
- Winner at 10+ contracts per leg: tastytrade by a wide margin (
$10.00vs.$26.00at 20 contracts, and$10.00vs.$65.00at 50 contracts).
Scenario 4: Active Futures Trader (50 E-mini Round Trips / Month = 100 Sides)
- Interactive Brokers:
100 × $0.85= $85.00 / month in broker commissions - tastytrade:
100 × $1.00= $100.00 / month in broker commissions - On Micro E-mini contracts (100 sides/month), the gap is larger: $25.00 on IBKR (
$0.25/side) vs. $75.00 on tastytrade ($0.75/side).

Platform & Workflow Comparison
Why Options Traders Love tastytrade
tastytrade was built by the team behind the original thinkorswim platform, and its workflow centers on probability of profit (POP), implied volatility rank (IVR), and multi-leg order management:
- One-Click Spread Building & Rolling: Iron condors, vertical spreads, strangles, calendars, and ratio spreads can be constructed, adjusted, and rolled to the next expiration cycle in two clicks directly on the curve or table view.
- Futures Options Integration: Unlike many retail platforms that wall off futures from equities, tastytrade lets you view and trade options on
/ES,/NQ,/CL, and/GCfutures alongside equity ETFs with unified portfolio delta/theta weighting. - Trade-Offs: Charting is functional for options strike selection but is not designed for multi-monitor price-action scalping, custom Pine-style indicators, or automated API strategies. Many tastytrade users chart on TradingView (see our TradingView vs thinkorswim comparison) and execute on tastytrade.
Why Multi-Asset, Global & Algorithmic Traders Choose Interactive Brokers
Interactive Brokers prioritizes execution breadth, financing efficiency, and global market access:
- SmartRouting & Pro Order Types: Trader Workstation (TWS) and the newer IBKR Desktop support over 100 order types and algorithms (VWAP, TWAP, pegged-to-midpoint, conditional bracket orders, and BookTrader Level II DOM ladders).
- Global Accounts & Multi-Currency Balances: European, UK, Canadian, and APAC traders can fund in their local currency, convert spot FX at institutional interbank spreads (~0.2 bps, $2 minimum), and trade US, European, and Asian exchanges from one account.
- API & Automation: Official Python, C++, Java, and REST/WebSocket APIs make IBKR the standard retail broker for systematic and algorithmic traders.
- Trade-Offs: Classic TWS has a steep learning curve and a dense, legacy Java interface, though the newer IBKR Desktop app modernizes charting and options chains for everyday traders.
Who Should Choose Which Broker?
- Choose Interactive Brokers if:
- You live outside the US (EU, UK, Canada, APAC) and want native local-currency funding and regulated local entities.
- You trade futures (especially Micros), international equities, spot FX, or use margin borrowing overnight.
- You want API access, algorithmic order execution (TWAP/VWAP), or direct market access routing.
- Choose tastytrade if:

- You want an intuitive, probability-first options chain and fast multi-leg rolling without configuring a complex workstation.

Frequently Asked Questions
Is Interactive Brokers or tastytrade cheaper for options trading?
It depends on contract count per leg. Interactive Brokers Pro charges $0.65 per contract ($1.00 minimum per order) on both opening and closing trades, making 1- to 15-contract round trips cheaper on IBKR ($1.30–$19.50 round trip vs. $1.00–$10.00 on tastytrade). Because tastytrade caps opening commissions at $10 per leg and charges $0 commission to close, orders of 16+ contracts per leg are cheaper on tastytrade (capped at $10 round trip before exchange and regulatory pass-through fees).
Can European and international traders open a tastytrade account?
Interactive Brokers is natively available across the EU, UK, Asia-Pacific, and North America with local currency funding (EUR, GBP, CHF, USD) and local regulatory entities. tastytrade is a US brokerage primarily built for US residents; while it accepts international applications from select countries, funding is USD-only via international wire and EU retail investors face PRIIPs restrictions on US ETFs.
Which broker is better for futures scalping and day trading?
Interactive Brokers charges $0.85 per standard futures contract per side ($0.25 on Micros) before exchange fees and offers direct API and BookTrader ladder execution. tastytrade charges $1.00 per standard E-mini contract per side ($0.75 on Micros) and integrates futures options and volatility skew analysis cleanly on the same chain.
Does Interactive Brokers or tastytrade have lower margin rates?
Interactive Brokers Pro consistently publishes benchmark-plus tiered margin interest rates that are significantly lower than standard retail brokerage margin rates, making IBKR the stronger choice if you hold leveraged equity positions overnight.
