IG: Known for its user-friendly approach, IG provides a wealth of educational content for traders of all experience levels.
Interactive Brokers (IBKR): If you’re looking for advanced research tools and market data, IBKR is a strong contender.
TradeStation: TradeStation offers a powerful platform with educational resources geared towards building your trading strategies.
Good luck!
