3.6. What rules govern claim symbols?

Symbols must be composed of letters (from the English alphabet) and/or numbers. They are not case sensitive (i.e. "Bush" and "BUSH" refer to the same claim), although the case that was used to create the claim is saved and is used in many places. The maximum length is 16 characters. Symbols will normally be restricted to about 6 characters unless they are conditional claims (which will be composed of the symbols of the underlying claims, separated by a special character).

Symbols with a | in the middle are for conditional claims which result in the value of the symbol before the | if the symbol after the | is true.

Symbols with a ~ in the middle are for conditional claims which result in the value of the symbol before the ~ if the symbol after the ~ is false.

Symbols starting with an @ are templates (used for creating claims with standard wording).

Symbols for recurring claims end with a number indicating the year followed by a letter indicating the settlement month similar to the way symbols for commodity futures are created. For example, a symbol for a consumer price report that is expected to be released in December 2000 might have a symbol of CPI0z. Note that the settlement month may be different from the time period which the underlying data describes (e.g. the CPI0z claim mentioned above would refer to the CPI report about November prices).

Here are the letters with the months to which they correspond:

Currently only one digit is used to indicate the year, but multiple digits may be used in the future.
