A Trading Member or a Trading Representative must not enter a buy order or a sell order on the Trading System if there is an existing opposite order from that same Trading Member or Trading Representative in the same security or futures contract for the same price. This Rule does not apply if:—
(1) the Trading Member or Trading Representative knows or ought reasonably knows that the orders are for different beneficial owners;
(2) the order is a type expressly permitted in a practice note published from time to time by SGX-ST as having a legitimate commercial reason and which is unlikely to create a false market; or
(3) the Trading Member or Trading Representative can otherwise establish that the purpose for which the order was made was not to create a false market.
Refer to Practice Note 13.8.1.
