What a Trading Account Is and How It Works
When you open a trading account, the broker typically holds your cash and investments and executes orders on your instruction. Cash is usually deposited from a linked bank account, and settled trades update your holdings within the account. Many brokers offer several account structures: standard taxable accounts, tax-advantaged accounts where local rules allow, margin accounts that permit borrowing against holdings, and derivative accounts such as CFD accounts in jurisdictions where they are permitted. Each structure carries different rules, eligibility requirements and risks, so the account type you choose matters as much as the broker you choose. Definitions of terms used here are available in the Glossary.
- A trading account holds cash and investments and routes your buy and sell orders through a broker.
- Account types include cash, margin, tax-advantaged and derivative accounts, each with different rules.
- Margin and CFD accounts involve leverage, which magnifies both gains and losses.
