For structured warrants:
(a) The no-cancellation range will be the wider of the following:

(i) the average of the last quoted bid price and the last quoted offer price for the structured warrant immediately preceding the Error Trade; or
(ii) the average of the market prices as quoted by at least three Designated Market-Makers of structured warrants. The Designated Market-Makers will be selected randomly by SGX-ST, but will not include any Designated Market-Maker who is involved in the Error Trade that is under review.
