From 12 March 2013, to enhance the transparency of market activities, SGX will publish daily reports on the total value and volume of short sales for each counter. Accordingly, from 11 March 2013, SGX will require that all sell orders on their securities markets be marked.
This means that you must indicate - based on what you know about your position - whether your sell order is a short sell or normal sell order. The sell order will not be accepted if you do not indicate this to your broker or on the trading platform. If you realise that you incorrectly indicated a sell order and it has been executed, you must - before 2pm on the next working day - ask your broker to correct the order.
It is your responsibility to ensure that the sell order is accurately indicated. Under Section 330(1) of the Securities and Futures Act, it is an offence to deliberately make an incorrect indication as this may be construed as an attempt to manipulate the market or as intentional false reporting to SGX.
