I believe if this rule were to pass, the markets will be leaving themselves open to foul play. Market makers and Isda banks could use this ruling to create fake liquidity to either apply downward pressure in a security, through the increase of supply. Or avoid margin calls from bad plays. Giving themselves an unfair advantage over every other investor on the planet.
Ultimately this could easily remove fair price discovery and will only benefit the institutions that are authorised to use these facilities.

Thank you for your time.
Kind regards,
Brynley
