11.5.5

For all other securities or futures contracts, excluding bonds:

(a) The no-cancellation range will be determined as the wider of the following:
(i) a lower limit of 20 minimum bid sizes less than the Reference Price, and an upper limit of 20 minimum bid sizes higher than the Reference Price; or
(ii) a lower limit of 95% of the Reference Price, and an upper limit of 105% of the Reference Price.
(b) Subject to Rule 11.5.5(c), the Reference Price of the no-cancellation range for the security or futures contract will be the price of the last good trade.
(c) SGX-ST may, in its discretion, use an alternative price as the Reference Price for the no-cancellation range if:
(i) the price of the last good trade is not available; or
(ii) SGX-ST deems the price of the last good trade to be unreliable or inappropriate as a Reference Price.
(d) Where SGX-ST is of the view that no appropriate or reliable Reference Price is available, SGX-ST will not establish a no-cancellation range for that Error Trade.

Refer to Practice Note 11.5.5(c).
