Notes:

  1. By convention, a positive risk array value represents a loss for a single long position, and a negative risk array value represents a gain for a single long position. "Long" in this context means long the instrument, not the market; a long put is a long position.

  2. Risk array values are denominated in the performance bond currency for the combined commodity in which the specified contract is contained.

  3. If the Risk Array Exponent specified on the type 2 record for the combined commodity in which this contract is contained is not zero, then the risk array values specified in the file must be multiplied by 10 to raised to Risk Array Exponent power. In other words, shift the decimal point rightward this number of places.

  4. The Option Contract Day or Week Code field is used to distinguish option series which expire at different times than the standard monthly options.  For standard monthly options, this field will contain zeros or blanks.  For other options, this field will typically contain "W1", "W2", etc. - for weekly options expiring in week 1 of the month, week 2 of the month, etc. - or a two-digit day of the month, for flex options or other options for which the exact expiration day is specified.  The Futures Contract Day or Week Code is intended to be used analogously to distinguish futures which expire at different times than standard monthly futures.

  5. The Underlying Commodity (Product) Code field is an optional field and is not required for the performance bond calculation. If present for any particular option, it indicates the product code of the underlying future, combination, or cash instrument.

  6. The Implied Volatility field is optional. Implied volatilities may be as large as 9999% and may be expressed to a precision of .0001%. For example, 00157235 means 15.7235%.

  7. Product type codes are PHY for Physical, FUT for Future, CMB for Combination, OOP for Option on Physical, OOF for Option on Future, OOC for Option on Combination.

  8. For a given product family, either type "81" and "82" records are provided, or type "83" and "84" records are provided.   If a non-zero value is defined for the risk array decimal locator on the type "2" record for this product family, then type "83" and "84" records are provided.  Otherwise the standard type "81" and "82" records are provided.

    Type "83" and "84" records allow risk array values to be specified with up to 8 digits of precision and with a specified assumed number of decimal places.  So they would typically be used if risk array values need to be specified to the penny or even to greater levels of precision.
