DDE
Dover Downs Gaming & Entertainment Inc
stock NYSE

For investing, Fidelity is the best that I've used. Schwab and Vanguard weren't as good.
For trading, I've used Interactive Brokers TWS for 20+ years. The platform isn't the most user friendly and the learning curve takes some time but once you figure it out, it's no problem. Instant execution if trading at the market and confirms and account information updated instantly. Once tickers are set up (equities, single options, combos), you can place trades in 3-4 clicks. Even faster if you use hot keys.
Margin rates are low and they make an effort to locate hard to borrow stocks, a good thing since I frequently short stocks.
While I no longer use it, their DDE connection allowed for having Excel spreadsheets update in real time so that enabled me to have my number crunching analysis in real time.
Also, take a look at ThinkOrSwim. It's an excellent platform. Compare the two and pick what suits you the best.
