Scope: This document gives an overview of existing and currently used financial instrument identifiers. It shows which instrument identifiers, ticker symbols and proprietary codes are assigned via a standardized scheme to instruments of all asset classes. It focuses on providing an overview of the landscape and not on evaluating the schemes. Several aspects of the detailed trade cycle (a few examples being book building/primary, order entry management, execution management and trade confirmation matching) are excluded as their complexity would reduce the readability of the overview. Similarly, the level of complexity involved in properly representing the shifting perspectives of what is considered a financial instrument, based on a particular function being performed, is excluded.Cross References:ISO 20022-5ISO 20022-1ISO 15022-1ISO 10383ISO 20022-3ISO 20022-8ISO 4217ISO 20022-4ISO 6166ISO 20022-7ISO 3166-1ISO 10962ISO 20022-6ISO 15022-2ISO 20022-2All current amendments available at time of purchase are included with the purchase of this document.
