It will no longer rewrite unless it’s necessary: When a roll is detected, a Split and/or Dividend influences the output, it is a historical correction, or an underlying conversion is made. Depending on the size of your portfolio, you will see a reduction in the time it takes to perform a daily update*, especially with large stock portfolios, where volume corrections are transmitted. Futures contracts, and continuous contract files are corrected, too, without a rewrite, when prior day corrections are transmitted.

  • The Roll Schedule Report has been updated when specifying the expected roll dates for continuous contracts that roll on days prior to the expiry date. The formulation had not been updated to consider holidays that occur between the expiry date, and the number of trading days prior to the expiry date.

Build 501:

  • Expiry Dates have been added to Settlement Reports.
  • Nth Nearest Futures hold onto the Nth Nearest contract as long as possible until the next Nth contract has begun trading, filling gaps that were previously encountered at times when not using the Strictly Use Absolute Nearest setting.
  • Nth Nearest Futures and Back Adjusted contracts have a new setting when Calendar Date rolling with Days/Months prior from the End of the Month. Roll Prior to Non-Trading Days can be checked so that in cases where you roll a month or more prior, 1-2-3 days before the End of the Month, the software will not roll into the next month if the last calendar days are a weekend of holiday.

Build 500:
