When the answer depends on your account
Several answers change with the account you hold: a cash or margin account, a taxable account or an IRA, a prop firm's own rule book, a fund's prospectus. The guides say where that happens and which document to open, whether that is a fund's holdings page, your broker's margin rules or your Social Security statement.
For the vocabulary behind the answers, see the definitions. For the same subjects argued as trading rules, see the strategies.
