Passing Arguments to Formula

After defining ‘BIF’ as,

BIF=$1-$2

you can subtract any two instruments by passing arguments, or symbols, as follows:

BIF(<symbol>,<symbol>)

For example, if you wanted to subtract the December S&P from the S&P cash price, you would enter:

BIF(SPX,SPZ2)

Relationships can also be defined for different prices of the same instrument.

F_RANGE=$1.high-$1.low
