Uptick/Downtick Ratio. In technical analysis, a ratio of block trades on a security conducted on an uptick (that is, at a higher price than the previous trade) to those conducted on a downtick (that is, at a lower price). Generally speaking, buyers initiate uptick transactions. A high ratio is therefore an indication that there are too many buyers and that the security may soon undergo a price correction. As such, a high ratio is a bearish indicator.
