Such policies and measures can be amended by the Company at any time in its sole and absolute discretion. The Company may also take steps to prioritise, reduce, decrease or moderate the volume of Order Management Requests (including, but not limited to, by rejecting Order Management Requests or prioritising certain Order Management Requests). Where an Order Management Request is rejected by the Trading Platform, an Exchange User may then choose to resubmit or change such Order Management Request.

Trade Execution

9.18.

Order, Trade and Position Amendment or Cancellation

9.21. The Company may, in its sole and absolute discretion, enter into a supplemental or off-setting Trade with an Exchange User or take any other steps to amend, adjust, close, reverse, Liquidate, mitigate, off-set, deleverage or settle (as applicable) any Order, Trade or Position in respect of an Exchange User:
