FIX Protocol - Closing Specific Positions in Hedging Account

Developers
1

I have a hedging account and am using FIX 4.4 protocol via ctrader_fix Python library.

Issue:

  • When I place an opposite order, it creates a NEW hedge position
  • I cannot close specific positions by their Position ID (field 721)

Questions:

  1. How do I close a SPECIFIC position by its Position ID in a hedging account?
  2. What FIX message type should I use?
  3. Are there broker-specific fields I need to include?
  4. Does cTrader support position-specific closing via FIX?

My current approach:

  • NewOrderSingle (D) with opposite side → Creates hedge
  • OrderCancelRequest (F) → ORDER_NOT_FOUND

Please provide the correct FIX method for closing specific positions.

Thank you!
