Stochastic Oscillator
Following the RSI oscillator, another type of indicator that helps traders determine whether an asset is currently overbought or oversold is the Stochastic oscillator. Its strength lies in comparing the current closing price with the price range over a certain period, most often 14 days. This provides signals about potential price reversals, which can be valuable when deciding whether to enter or exit a trade.

How the Stochastic Oscillator Works
The indicator also moves within a range from 0 to 100 and consists of two lines – %K and %D. The %K line represents the current value of the oscillator, while the %D line is its smoothed average, often used as a signal trigger. Traditionally, values above 80 are considered overbought, and values below 20 are considered oversold.
How to Interpret the Signals
The most common way to use the Stochastic is to observe the moment when the %K line crosses the %D line. If %K is rising and crosses %D upward in the oversold area, it may indicate a buying opportunity. Conversely, if %K is falling and crosses %D downward in the overbought area, it may be a signal to sell. Just like with RSI, traders also monitor divergences between the price and the oscillator itself—for example, if the price reaches new highs but the Stochastic does not, it may be a warning that the uptrend is losing strength.
Limitations of the Indicator
The Stochastic oscillator is very sensitive, which means it can generate many false signals. For instance, if the price of the underlying asset is in a strong trend, the Stochastic will likely remain in the overbought or oversold area for an extended period without the expected correction occurring. Therefore, it is always advisable to look for additional confirmation and view the situation in a broader context. An illustrative example might be when the price is above the 50-day moving average, which implies that only buy signals would be valid.
Conclusion
In conclusion, it can be stated that the Stochastic is a type of oscillator that can simply and clearly help better time trades. It highlights situations when the price may be temporarily too high or too low and provides signals of a possible reversal. However, it works best when combined with other analytical tools and with thorough risk management, making it a reliable addition to a trading system.
