Stochastic Oscillator Formula

fast stochastic oscillator

It allows us to analyze the speed of trend development. For example, when the market is in uptrend and momentum slows down, it may mean that the trend is getting weaker, and reversal is coming. Hence, momentum helps traders define whether the market is going to continue, or the trend can be extended over some direction . In a trend-following strategy, traders monitor the stochastic indicator to ensure it stays crossed in one direction. This signals that upward momentum has slowed, and a reversal downward may take hold.

technical analysis tools analysis, on the other hand, uses charts and various technical indicators to forecast market conditions. Are the highest and lowest prices in the last 5 days respectively, while %D is the N-day moving average of %K (the last N values of %K). Usually this is a simple moving average, but can be an exponential moving average for a less standardized weighting for more recent values. There is only one valid signal in working with %D alone — a divergence between %D and the analyzed security.

There is some debate as to the origins of the stochastic oscillator. Especially the %D indicators we will cover later in the article. Ralph Dystant was the original creator of the indicator. However, George C. Lane is perhaps more commonly credited for his role in popularizing it.

George C. Lane, in an intellectual epiphany, developed the stochastic oscillator in the late 50s. This important technical indicator calculates the momentum of stock price changes, and is defined by these equations . I would not advise beginner traders to combine the RSI and stochastic oscillator. If using them together, they will likely confuse you due to the high frequency of alerts and fake signals.

  • The principle of how this calculator works is straightforward.
  • Usually, the period of the stochastic oscillator refers to the period of the %K curve.
  • On the other hand, a bearish signal comes up when the two lines of the oscillator makes a crossover above the overbought level.

However, as you will see often, it is not a reliable indicator to use these crossovers. However, as you will find, at times, the two lines of the Stochastic will remain in the overbought level for a while. Similarly, at times, the two lines will remain in the oversold level while the price is falling. As shown above, a sell signal emerged when the two lines intersected while being above the overbought level. A buy signal emerged when the same happened in the opposite direction. Instead, in technical analysis, they look at charts and use various technical indicators to help them predict.

Volume Weighted Average Price (VWAP)

%Ki — is the oscillator’s %K line value of the period being calculated. On the following picture, you can see examples of the Overbought and Oversold signals. On the following picture you can see an example of a bear set-up resulting in a tradable top at the next climb up followed by a bearish downtrend.

However, you may miss a significant element of a changing trend due to the lag before you decide to buy or sell. You can adjust the full stochastic oscillator indicator variables to assist with your specific investment strategy, lengthening or shortening the periods, and adjusting the SMA. Let’s say you speak to two traders independently and ask them what the stochastic oscillator shows.

We will do it using the stochastic with 21, 7, and 7 parameters. First, let’s look at how to add and set stochastic oscillator best settings for intraday timeframes. Here, the signals are a cross of %K and %D lines above 80% and below 20%. Later, we will talk about momentum indicator signals in detail.

Stochastic Oscillator Overbought Downturn

A bearish divergence forms when price records a higher high, but the Stochastic Oscillator forms a lower high. This shows less upside momentum that could foreshadow a bearish reversal. Once a divergence takes hold, chartists should look for a confirmation to signal an actual reversal. A bearish divergence can be confirmed with a support break on the price chart or a Stochastic Oscillator break below 50, which is the centerline. A bullish divergence can be confirmed with a resistance break on the price chart or a Stochastic Oscillator break above 50. Moving average convergence/divergence is a momentum indicator that shows the relationship between two moving averages of a security’s price.

stochastic oscillator chart

When working with a buy trade, it should be placed at the upper boundary, during a sell trade – at the bottom band. Try to use a stochastic oscillator with your favorite trend indicator. Follow these three simple rules, and you will be surprised by the result. We enter the market at the close of the breakout bar where the lowest price is located . When trading gold, it’s not recommended to use overbought/oversold signals even with a line crossing.

Calculate the Stochastic Oscillator for a Stock

Rather than measuring price or volume, the stochastic oscillator compares the most recent closing price to the high-low range of the price across a fixed amount of past periods. The indicator’s goal is to predict price reversal points by comparing the closing price to previous price movements. The closing price tends to close near the high in an uptrend and near the low in a downtrend. If the closing price then slips away from the high or the low, then momentum is slowing.

The stochastic oscillator and the relative strength index are both price momentum tools used to predict market trends. While often used in tandem, there are notable differences between the two indicators. Stochastic oscillator charting typically consists of two lines. A white line, known as the %K line, will appear below the chart when the stochastic indicator is applied and reflects the actual value of the oscillator. And a red – referred to as %D – is the three-period moving average of %K.

Similarly, an won’t automatically rise in price just because it is oversold. Overbought and oversold simply mean the price is trading near the top or bottom of the range. In a basic overbought/oversold strategy, traders can use the stochastic indicator to identify trade exit and entry points. Overbought and oversold levels are useful for predicting trend reversals. When the stochastic lines are above 80, the indicator signals that the instrument is overbought. When the stochastic lines are below 20, it signals that the instrument is oversold.

There are no 100% accurate instruments of technical analysis. It provides plenty of signals, but some of them are false. This is one of the simplest trend strategies that allow traders to get good results.

Thinking of any departure from the norm as a potential turnabout. Several situations may occur where the two indicators point in opposite directions; nevertheless, never a reversal occurs. Learning how to anticipate the market using this indicator can be useful if one of your goals is to become an active trader.

However, most traders don’t rely on the stochastic oscillator alone. Most of the successful trading strategies imply a combination of stochastic with other tools of technical analysis. Minimum periods of %K and smoothing lines are ideal for the 5-minute chart. They help get a sufficient number of signals, most of them are useful.
