Position Calculations

Current position totals are calculated as overall long and short positions for both futures and options per Executing Firm ID. The current position totals are defined as the Specific Listed Contract Margin Ratemultiplied by the number of contracts, which is an aggregate of open orders and fills per product complex. Product complex values are then aggregated to the total overall position.

 

  • Quotes (Mass Quotes) are not included in open position calculations. Fills resulting from quotes are included in the filled and total position.
  • The following are included in the filled and total position, but not the open position.
    • User Defined Spreads (UDS) covered instruments
  • Positions are maintained separately for each futures product complex and for each options product complex. Then futures product complex positions are aggregated and options product complex positions are aggregated.
  • Positions are calculated continuously. Filled Positions are reset at the end of each trade day at 16:30 CT.

Note: Good 'til Cancel (GTC) and Good 'til Day (GTD) orders are included in the position calculation for the given Executing Firm ID / Exchange group at the beginning of the trading week.

  • Submitted orders that trigger a violation at 100% of the limit will not be rejected as long as the order does not violate product and credit limits. Any subsequent orders will be rejected.
