Price alerts. Price alerts should trigger when the order price is far away from the prevailing market price in that it deviates by:

(a) a certain percentage; or
(b) a certain number of ticks,

as compared to the prevailing market price. The prevailing market price may be the last traded price, the previous settlement price, the closing price or the opening price, as appropriate.
