IBKR Lite vs IBKR Pro -- which to choose

IBKR Lite (free tier):
  $0 commissions on US stocks and ETFs.
  Uses payment for order flow (like Robinhood).
  Good for casual investors who want IBKR's research without complexity.

IBKR Pro (professional tier):
  $0 or $0.005/share -- automatically uses whichever is cheaper for your order.
  No PFOF: 'Smart Routing' finds the best price across all exchanges.
  Access to all global markets and professional-grade data feeds.
  Best for active traders placing large orders (1,000+ shares).

Global market access -- IBKR's biggest advantage

IBKR provides access to markets most US brokers don't offer:
  US: stocks, options, futures, forex, bonds, ETFs, mutual funds.
  Europe: London, Frankfurt, Paris, Amsterdam, Zurich, Milan.
  Asia: Tokyo, Hong Kong, Singapore, Sydney.
  Forex: 24 currencies at institutional spreads.
  Crypto: Bitcoin and Ethereum through regulated custodians.
  Precious metals: gold and silver spot trading.

If you need to buy international stocks directly (not US-listed ADRs), IBKR is essentially the only retail option.

Margin rates -- IBKR's second biggest advantage

IBKR charges the lowest margin rates in the US retail industry:
  IBKR Pro: ~5.8% annual (2024).
  Robinhood Gold: ~6.5%.
  Fidelity: ~9.25-12% depending on balance.
  Schwab: ~9.5-12%.

On $50,000 borrowed: IBKR saves $1,500-$3,000/year vs major competitors.
Only matters if you use margin -- beginners should avoid margin entirely.

Trader Workstation (TWS) -- IBKR's platform

TWS is IBKR's flagship desktop platform:
  Highly customizable with a steep learning curve -- extremely powerful.
  Portfolio analytics, risk dashboard, volatility surface lab.
  IBKR GlobalAnalyst: compare stocks across countries on normalized metrics.
  Paper trading: full demo account with real market data.

For beginners: use IBKR's simpler 'Client Portal' web interface instead of TWS.
IBKR Mobile app is solid for monitoring and placing basic trades on the go.
