stochastic oscillator definition

In addition to gauging the strength of price movement, the oscillator can also be used to predict market reversal turning points. The stochastic oscillator is a momentum indicator that looks at price relative to the price range over a specific period. The stochastic oscillator can be used to identify trend reversals and overbought or oversold levels. The stochastic oscillator lies in the theory that prices will close near to high if the trend is upward.

  • The first chart is the traditional (fast) stochastic oscillator indicator with a smoother %D trend line based upon the %K factor.
  • Readings above 80 for the 20-day Stochastic Oscillator would indicate that the underlying security was trading near the top of its 20-day high-low range.
  • The stochastic broke below 80 (1), so a trader would expect a further price decline.
  • As you can see in the charts above, the fast stochastic oscillator can be fairly volatile, often trading above or below the 80 and 20 levels for a short period of time.
  • The signal line crosses and moves below 80 did not provide good early signals in this case because KSS kept moving higher.

Meanwhile, the RSI tracks overbought and oversold levels by measuring the velocity of price movements. The stochastic oscillator is included in most charting tools and can be easily employed in practice. The standard time period used is 14 days, though this can be adjusted to meet specific analytical needs. The stochastic oscillator is calculated by subtracting the low for the period from the current closing price, dividing by the total range for the period, and multiplying by 100.

What are some strategies for using the Stochastic Oscillator in wealth management?

It’s essential to keep in mind that the stochastic oscillator is a momentum indicator that shows recent price action movement is in any given market and not the direction or trend. The slow stochastic is less sensitive to price movement changes, while the fast stochastic oscillator line responds quickly to the underlying security price changes. The stochastic indicator is classified as an oscillator, a term used in technical analysis to describe a tool that creates bands around some mean level. The idea is that price action will tend to be bound by the bands and revert to the mean over time.

It’s a general belief that momentum tends to change direction before price. This allows traders to use the stochastics to be ahead of price changes. The indicator moves stochastic oscillator definition between 0 and 100 to indicate the momentum of the security. If you have data on the closing prices of a security, you can import that into Excel in order to compute %K.

What is a Stochastic Oscillator?

The stochastic oscillator indicator is extremely flexible, and you can adjust the periods and SMA variables to suit your investment plan. However, especially when looking at limited periods, there will be occasions where the indicator will create a false signal. Therefore, it is sensible to consider other means of technical analysis to clarify whether a potential change in momentum indicated by the stochastic oscillator is also reflected elsewhere. You will also come across what traders refer to as the %D stochastic oscillator indicator. The %D removes many of the short-term fluctuations in the %K base chart. That gives it smoother trend lines which are often easier to read.

NTAP declined below its June low and the Stochastic Oscillator moved below 20 to become oversold. Traders could have acted when the Stochastic Oscillator moved above its signal line, above 20 or above 50, or after NTAP broke resistance with a strong move. Regular divergences are stronger, while hidden divergences should be confirmed with more reliable signals and analysed by considering the overall market trend. The stochastic consists of two lines – %K and %D, which move within the range. 14 is a standard setting, so we will use it to explain the oscillator. Understanding a stochastic oscillator doesn’t require advanced knowledge.

Conversely, the %K line crossing from above to below the %D stochastic line gives a bearish sell signal. Divergence occurs when a security price makes a new high or a new low, not reflected by the stochastic indicator. The stochastic reading for a possible overbought market condition occurs when it’s above 80. When this happens, a sell signal is generated once the oscillator reading returns below 80. In short, the difference between the slow stochastic and fast stochastic indicators can be analogous to the difference between a sports car and a limousine. The overbought line shows price levels within the top 80% of the most recent price range (that is, high-low) across a defined period, usually 14 by default on all timeframes.

Furthermore, the stochastic indicator provides great insight when timing entries. To avoid such frustration, new traders ought to have a solid understanding of the underlying mechanics of the stochastic oscillator viewed in relation to present market conditions. Similarly, a bullish divergence occurs when the market price makes a new low but the oscillator does not follow suit by moving to a new low reading. Bullish divergence indicates a possible upcoming market reversal to the upside. The default setting for the fast-moving line (%K) is the previous three %K average, while the default setting for the slow stochastic, or %D, is the three-day simple moving average of %K.

We will also take a look at how quickly you can adjust the sensitivity of the indicator. It gives you the ability to monitor the momentum of an asset’s price. Doing so lets you see whether it is potentially oversold or overbought compared to recent highs and lows.

  • It calculates the distance of the current closing price as it relates to the median of the high/low range of price.
  • The %D figure is traditionally a three-day rolling average over the %K three-day rolling average with the slow stochastic oscillator.
  • The oscillator tends to trend around a mean price level because it relies on recent price history, but it also adjusts (with lag) when prices break out of price ranges.
  • A reading of 100 indicates the highest peak during that designated time, while 0 indicates the lowest point of the current trading range.
  • For example, when the indicator gives a bearish divergence signal, the price may continue to move higher before reversing to the downside.
  • The price range traded may be above the closing price or below the closing price.
