(a) a quote shall be deemed to be a firm quote where it includes orders and quotes that under the rules of a trading venue can be matched against an opposite order or quote;

(b) quotes shall be deemed simultaneous two-way quotes if they are posted in such a way that both the bid and the ask-price are present in the order book at the same time;

(c) two quotes shall be deemed of comparable size when their sizes do not diverge by more than 50 % from each other;
