The role an online broker plays
At its core, a broker acts as an intermediary between you and the markets. You deposit money into an account, submit orders to buy or sell instruments, and the broker routes and executes those orders, then holds or records the resulting positions. Around that core function, firms differ in the instruments they offer, the account types available, the platforms they provide and how they charge. None of these details should be assumed from a firm's advertising. Each broker publishes its own legal documents, fee schedules and account terms, and those documents are the authoritative source for what the firm actually offers in your country.
- A broker takes your deposits, executes your orders and holds or records your positions.
- Instrument ranges, account types and platforms vary from firm to firm.
- A broker's own current documents, not marketing pages, are the authoritative source.
