PriceType Value 1

Value	Name	Field(tag)	First introduced	Deprecated
1	Percentage	PriceType(423)	FIX.4.2

The ratio between the current price of a bond and its par value adjusted for amortization or indexing and expressed as a percent. For example if a EUR1,000 bond is trading at EUR1032.50 its price is expressed as 103.25 or 103?. In the US this is usually referred to as the "dollar price" even in scholarly material and handbooks.

Notes

Note that values for Price when PriceType indicates Percentage are still represented as whole numbers - for example the above example would be recorded as 10325. See discussion at http://fixprotocol.org/discuss/read/b4b0e456

Error in FIX Specification:

The question mark following the 103 above comes from the fact that the spec (in the glossary) has the special character for a quarter - 1/4 - which did not translate correctly
