        (b) whether the execution of the transaction is likely to cause or contribute to a material change in the price of, or the market for, the security or futures contract, and whether the person involved or another person with whom the first person is collaborating may directly or indirectly benefit from alterations in the market or price;
        (c) whether the execution of the transaction involves the placing of multiple buy and sell orders at various prices higher or lower than the market price, or the placing of buy and sell orders that give the appearance of increased volume;
        (d) whether the execution of transaction is likely to coincide with or influence the calculation of reference prices, settlement prices and valuations;
        (e) whether parties involved in the transaction are connected or associated with each other;
        (f) whether the order or orders for the purchase (or sale) of a security or futures contract is or are entered with the knowledge that an order or orders of substantially the same size, at substantially the same time and at substantially the same price, for the sale (or purchase) of the security or futures contract has been or will be entered by or for the same or different parties (excluding Direct Business);
        (g) whether the execution of the transaction is likely to cause the price of the security or futures contract to increase or decrease, but following which the price is likely to immediately return to about its previous level;
        (h) whether the bid (or offer) is higher (or lower) than the previous bid (or offer) but is withdrawn or amended to avoid execution;
        (i) whether the volume or size of the order or transaction is excessive relative to reasonable expectations of the depth and liquidity of the market at the time;
        (j) whether the buy (or sell) order is likely to trade with the entire best offer (or bid) volume and part of the offer (or bid) at the next price level;
        (k) whether the buy (or sell) order forms part of a series of orders that successively and consistently increase (or decrease) the price of the security or futures contract; and
        (l) whether there appears to be a legitimate commercial reason for the transaction.
