Technical Analysis from A to Z Stochastic Oscillator

stochastic oscillator definition

In contrast, a buy signal is initiated when the oscillator shifts below 20 and then back above 20. The RSI is generally more useful for trending markets and stochastic oscillators in sideways or choppy markets.

  • In most trading platforms like MetaTrader, the default period is usually 14.
  • This shows less upside momentum that could foreshadow a bearish reversal.
  • When a divergence occurs between an indicator and prices, the indicator typically provides the clue as to where prices will head.
  • 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.
  • The Stochastic indicator shows an overbought condition when the chart is above level 80.

Stochastic oscillators tend to vary around some mean price level since they rely on an asset’s price history.

Recap: How to use the Stochastic indicator

The stochastic indicator is a two-line indicator that can be applied to any chart. The indicator shows how the current price compares to the highest and lowest price levels over a predetermined https://www.bigshotrading.info/ past period. The fast stochastic line is the 0%K line, and the slow stochastic line is the %D line. A bullish scenario is when the %K line intersects the %D line and goes above it.

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. A reading above 80 indicates that the instrument is trading near the top of its high-low range. A reading below 20 signals that the instrument is trading near the bottom of its high-low range.

How to read the Stochastic indicator with an additional level 50 is:

It gives readings that move between zero and 100 to provide an indication of the security’s momentum. The primary limitation of the stochastic oscillator is that it has been known stochastic oscillator definition to produce false signals. This is when a trading signal is generated by the indicator, yet the price does not actually follow through, which can end up as a losing trade.

What is the stochastic oscillator used for?

The stochastic oscillator is a valuable indicator for overbought and oversold conditions. Typically, readings above 80 indicate that the instrument is in the overbought range, and readings under 20 suggest oversold conditions. Furthermore, oversold and overbought levels can be used to forecast trend reversals.

Divergences form when a new high or low in price is not confirmed by the Stochastic Oscillator. A bullish divergence forms when price records a lower low, but the Stochastic Oscillator forms a higher low. This shows less downside momentum that could foreshadow a bullish reversal.

Limitations of Stochastic RSI

For example, the period% K is 5, then the formula is 100 x (the closing price of 5 days – lowest price of 5 days) / (the highest price of 5 days – lowest price of 5 days). So, how to trade using a good stochastic oscillator strategy, what is the secret of the stochastic indicator? The STOCHASTIC indicator shows us information about momentum and trend strength. As we will see shortly, the indicator analyses price movements and tells us how fast and how strong the price moves.

  • In this fast version of the oscillator, %K can appear rather choppy.
  • Keep in mind though, that when using it as a signal generator (especially for divergences and bull/bear setups) it is best when used going with the trend.
  • A stochastic indicator reading above 80 indicates that the asset is trading near the top of its range, and a reading below 20 shows that it is near the bottom of its range.
  • Much like with any range-bound indicator, Overbought/Oversold conditions are a primary signal generated by the Stochastic Oscillator.
  • Find the approximate amount of currency units to buy or sell so you can control your maximum risk per position.
  • It would not be unwise to use Stochastic along with other means of technical analysis such as trend lines to confirm the market direction.

Lane noted that the Stochastic Oscillator indicates the momentum of a security’s price movement. It is not a trend indicator for price as, for example, a moving average indicator is. The oscillator compares the position of a security’s closing price relative to the high and low of its price range during a specified period of time. In addition to gauging the strength of price movement, the oscillator can also be used to predict market reversal turning points. A longer look-back period and longer moving averages for smoothing produce a less sensitive oscillator with fewer signals. Yahoo was trading between 14 and 18 from July 2009 until April 2010.
