Glossary
Each entry says what the term means in a transaction, gives one example, and points to a guide. Definitions are educational. They are not the terms of your broker’s contract, which always win if they differ. Use the entry to slow down a product page.
If a product page uses a term loosely — especially yield, APR, margin or hedge — come back to the entry before you use the number in a decision. The alphabetical list below is the index.
