Stochastic Oscillator: What It Is, How It Works, How To Calculate

August 22, 2023

Volume indicators like On-Balance Volume (OBV) or Chaikin Money Flow can provide insights into the strength behind price movements, validating signals generated by the Stochastic Oscillator. Similarly, bullish divergences occurring near key support levels or within the context of a bullish reversal pattern https://www.xcritical.com/ may signal a potential upward reversal. However, it’s essential to exercise caution and not rely solely on divergences as trading signals, as false signals can occur, leading to losses if not properly confirmed. The stochastic indicator tracks the relationship of the closing prices in relation to the highs and lows over a defined number of days and smooths the result by using an average. Stochastics is an indicator and oscillator, presumably invented by George Lane as early as the 1950s George Lane referred to stochastics as a momentum indicator.

How do traders spot potential trend reversals using the Stochastic Oscillator?

The %D line is simply an average of %K over a specified number of periods. Using both lines, traders can gauge whether prices increase or decrease over time. Values above 80 indicate an overbought market, meaning that prices may soon come down; thus, it is a possible sell signal. The Oscillator can also form crossovers, which can be used as another indication of potential buying or selling signals. The stochastic oscillator is a key tool in securities trading because it helps gauge how strong the momentum of the market is. Thus the stochastic oscillator, or sto indicator, is an indicator used in standard deviation indicator trading to assess trend strength.

Placing the Example on a Timeline

The masterstroke was introducing an easy-to-understand range between zero and 100. In the words of Kelly Johnson, former lead engineer at Lockheed Skunk Works, “keep it simple, stupid.” Many traders today refer to this quote as the Cryptocurrency KISS principle. Therefore, it is best used along with other technical signifiers rather than as a standalone source of trading indicators. This two-line indicator can be entered into any chart and fluctuates between 0 and 100. The indicator demonstrates how the current price compares to the highest and lowest price levels over a predetermined past period. For example, as the period typically consists of 14 individual periods, this will be 14 weeks on a weekly chart.

Another limitation is its sensitivity to market noise, which can lead to frequent whipsaws, causing traders to enter and exit positions prematurely. Moreover, the default parameters of the Stochastic Oscillator may not be suitable for all market conditions or trading strategies, requiring adjustments and fine-tuning by traders. A stochastic oscillator is a technical analysis tool used to identify overbought and oversold conditions in the market. It compares a security’s closing price to its price range over a certain period of time and is typically expressed as a number between 0 and 100. In conclusion, the Stochastic Oscillator is a powerful tool that helps traders analyze market momentum and identify potential reversals or confirm trends.

Traditionally, readings above 80 indicate that the instrument is in the overbought range, and readings under 20 suggest oversold conditions. Stochastics is an unprofitable indicator, but others have higher success rates, such as Heikin Ashi charts, combined with the rate of change, RSI, and bullish chart patterns. Our testing has proven these indicators to be more effective, work on many timeframes, and are more successful in trading strategies. In conclusion, using the Stochastic Oscillator to generate buy and sell signals for day trading is unreliable. Investors should avoid relying on this indicator and use proven methods such as bullish chart patterns or Heikin Ashi charts for trading or modern portfolio strategies.

Since price is thought to follow momentum, the conjunction of these two lines can signal that a reversal may be on the way. For instance, if a stock is in a downtrend, but the stochastic oscillator shows a bullish divergence, it could signal a potential reversal to the upside. Traders might then look for further confirmation from other indicators or price action before initiating a long position. For instance, a trader might use trendlines, support and resistance levels, or moving averages to confirm the signals generated by the stochastic oscillator. The %D line smooths out the %K line and reduces the number of false signals. It’s also used to identify bullish and bearish divergences, which can signal potential trend reversals.

Conversely, when the Oscillator dips below 20, the asset is seen as oversold and may indicate a possible reversal upwards. This suggests that the price has fallen too much, too quickly, and could be poised for a bounce back. Can also select the line’s value, line thickness, value and visual type (dashes is the default).

Readings above 80 signal that the asset is trading near the top of its high-low range. Conversely, readings below 20 indicate that the asset is trading near the bottom of its high-low range. Readings above 50 suggest the asset is trading among the upper section of the trading range. Readings below 50 signal that the asset is trading in the lower part of the trading range. Our test results on 1-minute charts show a low success rate of 27 percent, and a 5-minute chart had a 20 percent success rate. The best way to succeed with Stochastics is by using a specific setup tested for higher reliability.

  • In particular, you would subtract the highest high observed in your lookback period from the last closing price and put this into the numerator of a fraction.
  • Conversely, when both lines are moving downward, it suggests strong downward momentum.
  • Unlike some indicators that primarily focus on trend direction or momentum alone, the Stochastic Oscillator offers insights into overbought and oversold conditions within a given trading range.
  • According to its creator, the stochastic oscillator does not follow price, volume, or anything like that.
  • Conversely, levels below 20 are considered oversold, indicating potential buying opportunities as the price may be poised for an upward reversal.
  • The stochastic oscillator is range-bound, meaning it is always between 0 and 100.

For example, if the 20-day Stochastic Oscillator is above 80 it indicates the underlying security is trading near the top of its 20-day high-low range. A reading below 20 indicates the security is trading at the low end of its high-low range. When the Stochastic Oscillator’s value exceeds 80, it is deemed to indicate higher demand, indicating a potentially high selling opportunity.

The settings on the Stochastic Oscillator depend on personal preferences, trading style and timeframe. A shorter look-back period will produce a choppy oscillator with many overbought and oversold readings. A longer look-back period will provide a smoother oscillator with fewer overbought and oversold readings.

The Stochastic Oscillator is typically utilized for analyzing shorter-term timeframes in the financial markets. It is particularly well-suited for assessing momentum and identifying potential reversal points within these shorter periods. Common timeframes include intraday charts such as 5-minute, 15-minute, or hourly intervals. However, it can also be applied to daily or weekly charts for swing trading strategies. While both indicators can identify overbought and oversold conditions, they have different calculation methods and sensitivity levels.

You can use Bollinger bands to provide insight into the normal volatility of the asset. An oscillator is a tool that creates high and low bands in between two extreme values, with an indicator that fluctuates inside these bounds to determine the trend. What works in stocks might not work in commodities like, for example, oil or natural gas.

The “slow” stochastic, or %D, is computed as the 3-period moving average of %K. In this article, we explain what the stochastic indicator is, how it performs, show some stochastic trading strategies, and how stochastic compares to the more famous Relative Strength Indicator. Divergence-convergence is an indication that the momentum in the market is waning and a reversal may be in the making.
