What is Oscillator in the Stock Market

The traders who are dealing with technical analysis in the stock market must come across the term oscillator indicator. The stock market is such a volatile field. Though there are thousands of tools and techniques available in the technical analysis, no one can fully predict the market. You can’t successfully analysis a stock only based on a single tool. The more you learn the usefulness of different tools together, the more accurate your analysis will be. Now, without further delay, let’s step into today’s main discussion, “What is Oscillator in the Stock Market?”. At the end of the article, I hope you will get all the answers to the question “What is Oscillator in the Stock Market?”

What is Oscillator in the Stock Market?

In simple word, oscillate means a subject which can swing in a regular rhythm, back or forth movement. In technical analysis, the oscillator indicator also works in the same way. If you are a newbie in the stock market, you may go through our previous article on the basics of technical analysis and indicators. Let’s get back to the oscillator. As I have stated that these types of indicators oscillate between a certain range. However, not all oscillators belong to the same category. Hence, we can categorize the oscillators into two separate sections based on their plot. So, these are the banded oscillator and centered oscillator.

Banded Oscillators

The specific category of oscillators oscillates between a range which is defined as 0 to 100. This particular range has separate zones, termed as overbought and oversold zones. Generally, a range between 0 to 30 considers as oversold zone while 70 to 100 is overbought zone. In one of my previous article, you can get an overall idea regarding overbought and oversold situations. Overbought indicates a current bullish market or a hint of an upcoming bearish market and vice versa. However, if we have jotted down the whole thing, a gist comes out. It is advisable to wait for the oversold level for getting a buying signal and overbought for selling signal.

Centered Oscillators

Now, this section of oscillators is not range-bounded. The name itself clarifies its features. These oscillators oscillate or fluctuate above or below a central line. It helps to identify the weakness-strength, direction-momentum of a stock price movement. When oscillator direction moves above the central line, bullish trend indication appear. So, in the case of the bearish trend, oscillator direction is below the central line. Our next cover point will be examples of different banded and centered oscillators.

Example of Banded Oscillators

There are various banded oscillators like RSI, Stochastic, etc.

RSI (Relative Strength Index)

The name RSI defines its meaning. With the help of this particular oscillator, traders can measure the strength of a trend. RSI works in a range from 0 to 100 as I mentioned above. We can easily identify the overbought and oversold situation from it. From RSI, we can identify the divergence scenario. Divergence happens when price and RSI (or any other banded oscillator) move in the opposite direction from one other.

Stochastic

Stochastic Oscillator measures the relationship between OHLC price (Open, High, Low, Close). It also helps to identify the overbought-oversold scenario. Generally, the stochastic calculation is based on 14-period data. The banded oscillators help traders to trade with support-resistance level. High range stochastic considers as overbought while low range means oversold. Here also divergence works well.

CCI (Commodity Channel Index)

CCI indicator comes under banded oscillator. When the range is above 100, considers as a strong price action or uptrend. Price action below -100 is downtrend or a weak price trend.

Examples of Centered Oscillators

One of the most widely used and well-known examples of the centered oscillators is Moving Average.

Moving Average

As I have stated before that centered oscillator works around a centerline. In moving average, there is a central line, the particular indicator oscillates around the line. When price moves under the MA signal line, consider as buying signal and moves above the MA line, considers as selling signal. The two most common usage of MA is SMA (Simple Moving Average) and EMA (Exponential Moving Average).

Divergence: Positive and Negative

So, by using the bounded oscillators, we can identify the positive and negative divergence or in other words bullish or bearish divergence. As I have already stated that, when a disagreement happens between price and oscillator movement, divergence occurs. Therefore, this pattern considers as the most significant trend identification of all time.

Positive or bullish divergence happens when price action establish a lower low while oscillator establishes a higher low.

In the case of negative or bearish divergence, the price makes a higher high where the oscillator makes a lower high.

The above two formulations are termed as regular bullish and bearish divergence. There are other two concepts of divergence using the oscillator, hidden bullish and hidden bearish divergence.

Features of Oscillator

  • Applying oscillators together with other indicators and charts give more prominent and accurate analytical data in the technical analysis of a stock.
  • Oscillators are more popular to provide information regarding current and upcoming market trend.
  • Banded oscillator often terms as a momentum oscillator.
  • Trend movement is easily identifiable with this type of indicator.
  • Support-Resistance level also a significant outcome of applying oscillator.
  • By identifying the support-resistance level, traders can point out the exact by-sell point in a stock.
  • On banded oscillator, you can draw trend-line in order to find out the next movement of the market. Besides price action, on banded oscillator also traders can draw a trend line.

Oscillator in the Stock Market FAQ

What are oscillators in technical analysis?

Oscillators are the indicators of technical analysis, that indicates the possibility of market movement. Basically, it oscillates between a limited range, that’s why it is called oscillator. It helps to identify the overbought and oversold situation of a stocks price.

What are the types of oscillator?

Structure wise, oscillators have two types, banded oscillator, and centered oscillator. Banded oscillator oscillates between a range like 0 to 100 or 0 to 200 and centered oscillator fluctuates above or below a central line.

How do you know if a stock is oversold?

One of the best ways to know about the overbought/oversold condition of the market is by using oscillators. For example, RSI, Stochastics, Commodity Channel Index, William % R, etc.

How does a stochastic oscillator work?

Stochastic oscillator comes under the banded version of oscillators. It compares a specific closing price of a stock to a range of its prices over a certain period of time. You can change the sensitivity of the oscillator by adjusting the time period.

Conclusion

However, if traders know every technique of oscillators usage, it can be very helpful for them to identify the market movement. In general, oscillators can trade with the trend and range if used in conjunction with other indicators. Here, in this article, I have tried to jot down all the points related to the oscillator in the stock market. Therefore, I hope the article “what is oscillator in the stock market” will be helpful to you.
