  • View current block/unblock instructions
  • Query Product/Exchange information
  • View block/unblock history (GUI only)
  •  Block/Unblock order entry at the following levels:
    • Execution Firm
    • Account
    • Futures/Options (derivative type)
    • Side
    • Product
    • Exchange
  • Cancel working orders at the following levels (API only):
    • Account + Execution Firm + Exchange
    • Account + Execution Firm + All Exchanges supported by Clearing Firm

CMFs can use their own certified risk management system or certified third-party risk management applications to programmatically send instructions to the API to Block, Unblock, and View Active blocks.
