Ref Values


Key Ref Values of function Price in Tradable refers to the values that are used to replace the original values associated with the key chain(s) specified in
Ref Keys

Note, the number N of key chains equals the number of columns of the range passed as input to the key Ref Keys, which in turn equals the number of objects specified in
Ref Objects
An array of K rows and N columns is expected here.
In the usual case where only one object with a corresponding key chain is affected, N = 1 and the array consists of only 1 column.
K can be any number.
In effect, the value of the affected key chain will be modified in an iterative fashion K times, thereby leading to the production of K corresponding output values.

The values entered here are used in the replacement of the original values according to the prescription defined in the respective type defined in key
Edit Methods

Note, the values must be of an appropriate type in order to be able to be used in the replacement process.
For example, if the applicable edit method is set to
Replace and the original value is of date type, the value here must be also a date.
But in the same example, if the applicable edit method is set to
Shift, the value here must be an object of type Period for the shift to make sense.

As another example, if the applicable edit method is set to
Replace and the original value is an object of type Set, the value here must be also an object of type Set that is used to replace the original object.
Exceptionally, in the same example, if the applicable edit method is set to
Shift, the value here can be a single number that is then used to shift all elements of the original Set object.

Note that for technical reasons the unit suffic specifier - such as (%) - is not supported by the key here.
