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.

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.
