Introduction
A true professional trader relied on macro analysis aided by fundamental analysis and microanalysis on the back of technical analysis. Generally, short-term trades depend on technical analysis and long-term trades extract more data from fundamental analysis. Both types of information have their pros and cons, making neither type better or worse than the other. Technical analysis is performed with the help of many useful indicators like support and resistance, Bollinger Bands , Fibonacci Retracement , and relative strength index (RSI). RSI is either simple or stochastic.
What Is RSI?
Relative strength index (RSI) tells you whether a stock or a crypto coin is overbought or oversold, by measuring the speed and magnitude of price changes. As you can view a chart of any asset on different time frames, you can also apply RSI indicators on different time periods. The standard or default settings is on 14 candles. It means if you choose 1D time frame, you can view last 14 days of price data and relative price changes projected by the chart. Similarly, last 14 1H, 4H, 1W candles are also shown when settings are adjusted accordingly. Instead of 14, you can view less or more candles for RSI.
What is Stochastic RSI?
Stochastic RSI can be defined as an indicator of an indicator that measures the strength of RSI. Where simple RSI measure the price momentum, stochastic RSI measures the changes in RSI, so it is called a second order oscillator. By oscillator, we mean that the indicator fluctuates to and fro around a line. Traders regard it as far more sensitive than simple RSI because it swing rapidly between 0 and 1 (or 0-100, depending on plot conventions).
Comparison of the Two
Major differences between the two indicators is that simple RSI is a relatively weak indicator when it comes to taking actions for a trade or inside a trade. The main reason of tis weakness is that simple RSI extracts data from the price action, which is highly volatile and hardly predictable. During a strong uptrend, RSI consistently remains well above 70, which is universally considered an overbought state. However, no reversal results as someone may predict from the readings of the indicator.
On the other hand, stochastic RSI is based on the movement of RSI line. This is where Stochastic RSI offers a practical advantage. Since it measures the momentum of the RSI itself, it responds more sharply to even minor shifts in buying or selling pressure. This increased sensitivity enables traders to detect early signs of trend weakening or reversal before they become visible in price movements. Moreover, by normalizing RSI within its recent range, Stochastic RSI highlights subtle overbought or oversold conditions that a simple RSI may overlook. In this way, it refines timing, improves entry and exit precision, and helps traders act more confidently within fast-moving or volatile markets.
How Stochastic RSI Works
Since the basis of Stochastic RSI indicator is the simple RSI, the only thing you need to do is to apply stochastic formula. The result is a single numerical rating that swings around a centerline (0.5), within a 0-1 range. The formula takes into account the closing price of an asset, but it also considers the highest and lowest points of the selected candles. The formula is given below:
Stoch RSI = (Current RSI – Lowest RSI)/ (Highest RSI – Lowest RSI)
As you can see, the formula is not concerned with the price action. Rather, it is related to the RSI indicator movement.
Interpreting the Data
Once you have set the stochastic RSI indicator as per your requirements, the next step is to interpret the data projected in front of you. The StochRSI indicator takes on its greatest significance near the upper and lower bounds of its range. Therefore, it helps you decide your entry and exit points in a trade. Moreover, trend reversals can also be predicted using this indicator. The indicator typically moves above or below the line that is drawn at 0.5. So, lower readings like 0.2-0.3 indicate oversold condition of the asset you are analyzing. Similarly, higher readings like 0.7-0.8 show that the asset is in the overbought territory and it should not be surprising if a red candle is formed next.
Pitfalls of Stochastic RSI Indicator
1.Frequent False Signals in Sideways Markets
The first major pitfall of using Stochastic RSI is the high number of false signals it generates during sideways or choppy markets. Because the indicator is extremely sensitive, it reacts to even the smallest fluctuations in price, frequently swinging between overbought and oversold zones without any meaningful change in trend. Such movement may be taken as false triggers of entry or exit by traders. Not only do traders lose money in the form of loss and trading fees but also suffer emotional setbacks. Losses can make them fall prey to revenge trading, which multiplies their losses.
2. Misleading Overbought and Oversold Readings in Strong Trends
The second weakness of stochastic RSI is shared by the simple RSI indicator, too. Strong uptrend is taken as a sell signal and strong downtrend as a buy signal. But keeping in view this interpretation, $BTC went flashed many buy signals during its consistent downtrend from November 2021 to December 2022. Yet, none of those signals was reliable. Similarly, Bitcoin has been in uptrend on higher time frames since it touched $15,500 region. Apart from a few healthy correlations, no real downtrend occurred so far. The digital gold has been making new ATHs every other month or so.
3. Inconsistent Performance Across Assets and Timeframes
The third pitfall is the absence of consistency across different assets and timeframes. The same parameter settings that work efficiently for one asset, such as $BTC/$USDT, may produce unreliable results when applied to another. This happens because volatility and market rhythm differ from one financial instrument to another. Many traders ignore this and assume that standard settings will fit all scenarios, which often leads to distorted and misleading readings.
Bottom Line
In a nutshell, stochastic RSI is a useful TA indicator that you can use to decide about the entry and exit points of your trades. The indicator is a great oscillator as it is based on another indicator instead of being dependent on the volatile price actions. However, as in any other tool, caution must be exercised while relying on it blindly as it is not without its drawbacks, which may ruin your trading journey.
