Tick

Tick is a minimum value of a price change. At present, depending on the security type and cost, the tick can amount to 1/16, 1/32, 1/64 of the USD, etc., although the decimalization is expected in the future when the tick will be 1/100 of the USD. When transmitting information about price movements, the terms “uptick” (one tick upwards) and “downtick” (one tick downwards) are also used.
