Extended Support for New York Sock Exchange Closures

The current holidays function covers holidays and non-trading days from 1950 to 2050. Using nyseclosures, you can determine all known and anticipated closures from January 1, 1885 to December 31, 2050.

• Provide the ability to specify the compounding frequency separately from the coupon frequency.

• Enable specification of a discounting basis. A discounting basis has two purposes in Price/YTM calculations:
