  "description": "Specifies the price of a financial instrument in a trade as a schedule of measures. A price generically expresses the value of an exchange as a ratio: it measures the amount of one thing needed to be exchanged for 1 unit of another thing (e.g. cash in a specific currency in exchange for a bond or share). This generic representation can be used to support any type of financial price beyond just cash price: e.g. an interest rate, a foreign exchange rate, etc. This data type is generically based on a schedule and can also be used to represent a price as a single value.",
