On an exchange, a trade in which a security was traded after another trade. There are three basic types of tick. A plus tick occurs when the price is higher than the previous trade. A minus tick occurs when the price is lower, and finally a zero tick happens when the price is the same. Ticks are recorded and published in real time throughout a trading day. Certain regulations govern the types of trade that can occur after certain kinds of ticks. See also: Zero-plus Tick, Zero-minus Tick.

A short-term technical indicator that describes the difference between the number of stocks whose last sale occurred on an uptick and the number of stocks whose last sale occurred on a downtick. A high positive TICK is generally considered a short-term signal of a strong market. Contrarians consider a high positive TICK to have bearish implications.

A tick is the minimum movement by which the price of a security, option, or index changes.

With stocks, a tick may be little as one cent. With US Treasury securities, the smallest increment is 1/32 of a point, or 31.25 cents.

An uptick represents an increase over the last different price, and a downtick a drop from the last different price.

The life cycle of Argasidae (soft) ticks consists of three life stages: larvae, nymphs, and adults.
These soft-shelled Argasidae ticks differ from hard Ixodidae ticks in several key characteristics: they have multiple nymphal stages; they feed rapidly, typically between 15 and 90 minutes; as adults, they can feed and reproduce repeatedly, are capable of surviving for several years between blood meals (73); and the spirochetes may colonize their salivary glands, rather than the midgut, allowing for rapid deposition after host attachment.
Antibody responses of laboratory mice to sequential feeding by two species of argasid ticks (Acari: Argasidae).
Tick paralysis (TP) is only transmitted by blood-feeding gravid adult female ticks by an incompletely characterized neurotoxin produced by the tick's salivary glands.11 Ticks are classified into three families: (1) the Ixodidae, or hard ticks; (2) the Argasidae, or soft ticks; and (3) the Nuttalliellidae, a much lesser known family, with characteristics of both hard and soft ticks.
Both Ixodidae (hard) and Argasidae (soft) ticks can be reservoirs of the organism with greater than 40 species of ticks serving as natural reservoirs that remain infected throughout life and can transmit the bacterium transovarially.
