TradeStation is one of the most complete and modern trading platforms that has everything you need. I just log on to the platform for stocks, options, futures, ETFs, etc. and it does not disappoint. Trades are super quick and you do not wait unnecessarily for anything. Every trade is reliable and I have always got the price I wanted. The charts with modern analysis tools and deep charting techniques make the workflow smoother and more convenient.
My only complaint is they do not have a Mac desktop version. The app is perfect and does not lag even for high-volume trades. The spreads are narrow and you always get the best prices on stocks on TradeStation.
