Article 30 If the Exchange makes a forced position reduction to a tin futures contract, the amount of the unfilled orders subject to the order fill, positions eligible to fill the unfilled orders, and the principles and methods for the order fill of unfilled orders shall be determined as follows:

(i) Amount of the unfilled orders subject to the order fill. The term “amount of unfilled orders subject to the order fill” means the total amount of all the unfilled orders submitted after the close of the base date at the limit price into the central order book by each Client who has incurred losses on net positions in the contract of an average level of no less than six percent (6%) for tin futures contracts, of the settlement price of the base date.

(ii) Positions eligible to fill the unfilled orders. The positions eligible to fill the unfilled orders include the net positions, on which the Client, as calculated using the above formula stipulated in the Risk Management Rules of the Shanghai Futures Exchange, records average gains for speculative purposes or for hedging purposes at no less than six percent (6%).

(iii) Principles for the order fill of unfilled orders. The order fill of unfilled orders shall take place in the order of the following four levels with regard to the amount of gains and whether such positions are speculative or hedging:

Level 1: Unfilled orders shall be filled with the speculative positions eligible to fill the unfilled orders of any Client with average gains on net positions of no less than six percent (6%) of the settlement price on the base date for the contracts in tin futures, or the Speculative Position Gains of Over 6%;

Level 2: Unfilled orders shall be filled with the speculative positions eligible to fill the unfilled orders of any Client with average gains on net positions of no less than three percent (3%) but no more than six percent (6%) of the settlement price on the base date for contracts with respect to tin futures, or the Speculative Position Gains of Over 3%;

Level 3: Unfilled orders shall be filled with the speculative positions eligible to fill the unfilled orders of a Client with average gains on net positions of no more than three percent (3%) of the settlement price on the base date for contracts in tin futures, or the Speculative Position Gains Below 3%; and

Level 4: Unfilled orders shall be filled with the hedging positions eligible to fill the unfilled orders of a Client with average gains on net positions of no less than six percent (6%) of the settlement price on the base date for contracts in tin futures, or the Hedging Position Gains of Over 6%.

(iv) Methods for the order fill of unfilled orders. If the amount of the Speculative Position Gains of Over 6% is greater than or equal to that of the unfilled orders, the unfilled orders shall be filled pro rata to the amount of the Speculative Position Gains of Over 6%. If the amount of the Speculative Position Gains of Over 6% is smaller than that of the unfilled orders, the Speculative Position Gains of Over 6% shall be filled pro rata to the amount of the unfilled orders. The residual unfilled orders, if any, shall be filled with the Speculative Positions Gains of Over 3% in the same manner as the foregoing, and if there are still orders remaining, the outstanding unfilled orders shall be filled to the Speculative Position Gains of Below 3%, and so to the Hedging Position Gains of Over 6%. Unfilled orders which eventually remain after all the order fills described above, if any, shall not be filled at all.
