This Calculator is a must have for spread traders! When spread trading two different futures contracts, it is important to equalize the value of each side of the spread Â? the short position in Contract #1 should be offset as closely as possible by a long position in Contract #2. Constructing and maintaining a perfectly balanced spread can be difficult due to differences in: -Currency denominations (e.g. two Nikkei 225 futures denominated in $USD and Yen) -Currency unit sizes (e.g. dollars and cents, pounds and pence) -Quote units (e.g. basis points and dollars) -Contract multipliers (e.g. full size vs. E-Mini S&P 500 futures) This pre-built Excel workbook allows you to simply plug contract parameters into 1 of 3 different Calculators, and balance the number of contracts to equalize the value of each spread leg.
