oi()

oi([nRelativeOffset] [, nNumBars [, Symbol ] ])

nRelativeOffset: Offset to bar. 0 is most recent bar, -1 is next bar, etc.
nNumBars: Number of bars to retrieve (a negative number)
Symbol: The symbol to retrieve data for.

oi(-1); gets the next-to-last open interest value for the current symbol
oi(0, "ES #F"); gets the most recent open interest value for ES
oi(0, -10, "ES #F"); gets the last 10 open interest values for ES and places them in an array
