The Board may impose any conditions it thinks fit on dealing or trading in a Designated Instrument. A condition applies from the date of declaration to all contracts of the Designated Instrument entered into on or after the date of declaration, or as indicated by the Board. For avoidance of doubt, the conditions may include:

(1) a requirement that Trading Members obtain margins from each customer in respect of the customer's dealing or trading in the Designated Instrument;
(2) [deleted];
(3) a restriction on dealing or trading in a Designated Instrument by a Trading Member if its outstanding contracts exceed 5% of the total issued shares or units of the relevant Issuer whose shares or units are designated or underlies the Designated Instrument, of the company whose securities comprise the underlying, or any other percentage the Board prescribes; or
(4) a prohibition on any sale unless the seller holds the Designated Instrument, or in the case of a Designated Instrument that is a futures contract, the underlying. A seller holds a security or futures contract, or underlying if, at the time of sale, he has the security, futures contract or underlying in an account maintained with CDP, or delivers the share certificates and executed transfer forms to the Trading Member.
