tickAudio Help (tĭk) Pronunciation Key
Any of numerous small, parasitic arachnids of the suborder Ixodida that feed on the blood of animals. Like their close relatives the mites and unlike spiders, ticks have no division between cephalothorax and abdomen. Ticks differ from mites by being generally larger and having a sensory pit at the end of their first pair of legs. Many ticks transmit febrile diseases, such as Rocky Mountain spotted fever and Lyme disease.
Main Entry: tick Pronunciation: 'tik Function: noun 1: any of numerous bloodsucking arachnids that constitute the acarine superfamily Ixodoidea, are
much larger than the closely related mites, attach themselves to warm-blooded vertebrates to feed, include important vectors of various infectious diseases of humans and lower animals, and although the
immature larva has but six legs, may be readily distinguished from an insect by the complete lack of external segmentation 2: any of various usually wingless parasitic dipteran
flies (as the sheep ked)
The minimum upward or downward movement in the price of a security.
Investopedia Commentary
Historically, stocks didn't trade in decimals. A
stock would move in amounts of 1/8, 1/16, or 1/32 of a dollar (the tick). This changed when the decimal system was brought in.
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.
tick 1. A jiffy (sense 1). 2. In simulations, the discrete unit of time that passes between iterations of the simulation mechanism. In AI applications, this amount of time is often left unspecified, since the only constraint of interest is the ordering of events. This sort of AI simulation is often pejoratively referred to as "tick-tick-tick" simulation, especially when the issue of simultaneity of events with long, independent chains of causes is handwaved. 3. In the FORTH language, a single quote character. [The Jargon File]
