**Stochastic Oscillator**
The Stochastic Oscillator is a technical indicator that measures the relationship between the closing price of a security and its price range over a given period of time. It is used to identify overbought and oversold conditions in the market.
**Formula**
The Stochastic Oscillator is calculated using the following formula:
«`
%K = 100 * ((C — L) / (H — L))
«`
where:
* %K is the current value of the Stochastic Oscillator
* C is the current closing price
* L is the lowest low over the lookback period
* H is the highest high over the lookback period
**Interpretation**
The Stochastic Oscillator is displayed as a line that ranges from 0 to 100.
* **Overbought:** When the Stochastic Oscillator is above 80, it indicates that the security is overbought and may be due for a correction or pullback.
* **Oversold:** When the Stochastic Oscillator is below 20, it indicates that the security is oversold and may be due for a rally or rebound.
**Parameters**
The Stochastic Oscillator typically uses the following parameters:
* Lookback period: The number of periods (e.g., days or candles) over which the highest high and lowest low are calculated.
* Smoothing period: The number of periods over which the %K line is smoothed.
**Applications**
The Stochastic Oscillator can be used for a variety of applications in Forex trading:
* Identifying overbought and oversold conditions
* Finding potential trading opportunities
* Confirming price action
* Setting stop-loss and take-profit levels
**Limitations**
The Stochastic Oscillator is not a perfect indicator and can be subject to false signals. It is important to use it in conjunction with other technical analysis tools and strategies.
