Stochastic Oscillator

Definition

A Stochastic Oscillator is a momentum indicator used in technical analysis to compare a specific closing price with a range of prices over a given period. This oscillator is expressed between 0 and 100, with values above 80 indicating that an asset is potentially overbought, while values below 20 may suggest that it is oversold. Developed in the 1950s, it helps traders identify trends and predict potential reversals based on price momentum.

Formula

The Stochastic Oscillator is calculated using the following formula:

\[ \text{Stochastic} = \frac{(C - L)}{(H - L)} \times 100 \]

where:

• \(C\) = Current closing price
• \(L\) = Lowest price over the look-back period
• \(H\) = Highest price over the look-back period

Examples

• If the current closing price of stock ABC is $50, with a 14-day highest price of $55 and a lowest price of $45, the Stochastic Oscillator would be calculated as: \[ \text{Stochastic} = \frac{(50 - 45)}{(55 - 45)} \times 100 = 50 \]
• A value of 50 suggests neutrality—neither overbought nor oversold.
