Stochastic Oscillator: How to Use This Popular Indicator

In the world of forex trading, technical indicators are essential tools that help traders predict trading opportunities and make informed decisions. One of the most popular indicators among traders is the stochastic oscillator. It is a technical momentum indicator that measures the price level’s relative strength in relation to its price range over a particular time frame. The stochastic oscillator is popular among traders due to its simplicity and efficacy in detecting overbought and oversold market conditions.

What is a Stochastic Oscillator?

A stochastic oscillator is a technical indicator that helps traders analyse the market movements by measuring the price level’s relative strength in relation to its price range over a particular time frame. The time frame is usually 14 periods, but traders can adjust it according to their trading strategy.

The stochastic oscillator consists of two lines, %K and %D, and oscillates between 0 to 100. The %K line represents the current market price’s relative position within the recent trading range, while the %D line represents a moving average of the %K line.

How to Calculate the Stochastic Oscillator?

The stochastic oscillator calculates the percentage difference between the current closing price and the price range’s high and low over the timeframe. The formula to calculate the stochastic oscillator is:

%K = 100 * [(C – L14)/(H14 – L14)]

Where,

C = the current closing price
L14 = the lowest low of the previous 14 periods
H14 = the highest high of the previous 14 periods

The %D line is a moving average of the %K line, calculated using the formula:

%D = 3-period moving average of %K

How to Use Stochastic Oscillator?

Traders use the stochastic oscillator to identify overbought and oversold market conditions. When the %K line crosses above the %D line and reaches the upper limit of 80, traders consider it an overbought market. When the %K line crosses below the %D line and reaches the lower limit of 20, traders consider it an oversold market.

Some traders also use the stochastic oscillator to identify divergences. A bullish divergence occurs when the price forms lower lows, while the stochastic oscillator forms higher lows. A bearish divergence occurs when the price forms higher highs, while the stochastic oscillator forms lower highs.

Limitations of the Stochastic Oscillator

Like other technical indicators, the stochastic oscillator also has some limitations that traders should consider while using it. The stochastic oscillator is a momentum indicator that signals a trend reversal or a trend continuation.

However, traders should not rely solely on the stochastic oscillator to make trading decisions as it is a lagging indicator that can give false signals during a strong trend. Traders should always confirm the signals with other technical indicators and price action analysis.

Conclusion

The stochastic oscillator is a popular and effective technical indicator that traders use to identify overbought and oversold market conditions and to detect divergences. However, traders should not rely solely on the stochastic oscillator to make trading decisions and should always confirm the signal with other technical indicators and price action analysis. With proper use, the stochastic oscillator can become a valuable tool in a trader’s arsenal to identify profitable trading opportunities.
