FIX 5.0 SP1 : PositionMaintenanceRequest <AL> message

Structure | Related Messages

Description

The Position Maintenance Request message allows the position owner to submit requests to the holder of a position which will result in a specific action being taken which will affect the position. Generally, the holder of the position is a central counter party or clearing organization but can also be a party providing investment services. Submission of a request may result in the following:

  • adjustement of both the long and short start of day position quantity
  • exercise of an option position into a position in the instrument underlying the option
  • abandonment of an option position that would otherwise exercise
  • netting of current day trades to change to the end of day long and short position
  • spreading of a position against other position in order to reduce margin requirements
  • pledge of a position for collateral purposes
  • large trader submission of the long and short quantities

The request may be submitted as either new, replace or cancel and may refer to a specific position or the previously submitted message. The request is always submitted as of a ClearingBusinessDate <715> and is therefore required. The parties both owning and holding the position are specified in the parties block.
