What stock traders need
Research quality. Fundamental data, analyst ratings, earnings calendars, and screening tools help you pick stocks.
Order types. Market and limit orders are standard. For active traders: stop, trailing stop, OCO, and bracket orders matter.
Execution quality. PFOF vs exchange routing. IBKR Pro's smart routing provides better execution. For investors trading frequently, execution quality matters more than commissions.
Extended hours trading. Pre-market and after-hours access varies. Webull offers the widest window (4 AM to 8 PM).
Fractional shares. Buy dollar amounts instead of whole shares. Fidelity ($1 minimum) and Robinhood ($1 minimum) lead in this category.
