The mechanics, without the marketing

Most broker guides start with the app. Start with the legal entity instead — it takes two minutes and it rules out more bad outcomes than anything else on the list.

Most beginner feature lists are written by people who are no longer beginners. Here is what changes outcomes in the first two years, and what does not.

Comparison tables are only as good as the question behind them. Most published ones answer a question nobody asked: which broker is best in general.

Every one of these has a published answer. The point of the list is that most people find out the answers after opening the account rather than before.

The honest answer has two halves: the custody arrangements at registered US brokers are strong and checkable, and they protect you against nothing that most people are actually worried about.

One of these has a CRD number and holds your money. The other is an interface. They are frequently marketed as the same thing.

Investor protection is narrower than almost everyone assumes, and the gap between what it covers and what people think it covers is where bad decisions live.

Commission-free trading is genuine. It is also the least significant line on most fee schedules, and it has made the rest of the schedule much harder to compare.

A brokerage account is a custody arrangement with an execution service attached. Understanding it in those terms explains almost everything else about how brokers behave.

Transferring is usually simpler than people expect and almost always cheaper than selling. The mistakes are avoidable, and expensive.
