The security being ordered
The security is identified by its ASX code. You must also specify whether the order is a buy order or a sell order.
Security code conventions
Equity
(share) codes are between 3 and 6 letters long. Fully-paid ordinary
shares are generally 3 letters long. They reflect as closely as possible
the issuing company’s name, e.g. the code for BHP is BHP.
Related
securities are usually the base code plus another 1 to 3 characters
indicating the type of security, e.g. BHP preference shares might have
the code BHPPA.
Warrant codes are 6 letters long:
- The first 3 letters are the base code, e.g. BHP.
- The fourth letter identifies the type of warrant.
- The fifth letter identifies the warrant issuer.
- The sixth letter identifies the warrant series.
Interest rate security codes are 5 letters long:
- The first 3 letters identify the issuer.
- The fourth letter identifies the type of security, e.g. an H indicates an unsecured note, G indicates a convertible note and P indicates a preference share.
- The fifth letter is the sequence code, e.g. ABCHC indicates the third unsecured note on issue by ABC.
