单选题

A.Stochastic oscillator

B.Relative Strength Index.

解析：The RSI is calculated from the ratio of total price increases to total price decreases over a chosen number of days, then scaled to fluctuate between 0 and 100 using the formula RSI=100 - [100 / (1 + ratio of increases to decreases)]. Stochastic oscillators are based on the highest and lowest prices over a chosen number of days. MACD oscillators are calculated based on exponentially smoothed moving averages.
