Thanks Bill, but according to the manual this is allowed:
MIN
- minimum value of two numbers / arrays
SYNTAX min( ARRAY1, ARRAY2 )
RETURNS ARRAY
FUNCTION Returns the smallest of the two parameters.
EXAMPLE The formula "min( CLOSE, 10 )" returns the closing price or
10, whichever is less. The formula "min(-14, 13)" always returns -
14.
In other words, I already make sure that the array MIN returns by
default (even if you use two numbers as inputs) is transformed into a
scalar/number by using LastValue(Min. . . .)
Any other thoughts appreciated.
