Stochastic Oscillator
The Stochastic Oscillator is a technical analysis tool used in forex trading to measure the overbought and oversold conditions of a currency pair. It is calculated using the following formula:
«`
%K = (Current Close — Lowest Low) / (Highest High — Lowest Low) 100
%D = 3-period simple moving average of %K
«`
Interpretation:
%K line: Represents the current closing price in relation to the price range over a specified period (usually 14 or 20 days).
%D line: Smoothes out the %K line to reduce false signals and provide a better trend indication.
Overbought and Oversold Conditions:
Overbought: When %K and %D are above 80, it indicates that the currency pair may be overbought and a potential correction might be imminent.
Oversold: When %K and %D are below 20, it suggests that the currency pair may be oversold and a potential reversal could be underway.
Trading Signals:
Buy signal: When %K crosses above %D from below in the oversold area.
Sell signal: When %K crosses below %D from above in the overbought area.
Additional Tips:
The Stochastic Oscillator is more effective in trending markets than in ranging markets.
Combine it with other technical indicators to improve trading signals.
Adjust the period settings based on the time frame of your trading strategy.
Consider using multiple moving averages of %K and %D for additional confirmation.
Example:
In the image below, the Stochastic Oscillator is applied to the EUR/USD currency pair on a 15-minute chart. The %K line (blue) is above the %D line (red), indicating an overbought condition. This might suggest that the euro (EUR) could weaken against the US dollar (USD) in the near term.
