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.
