•RSI calculates average upward and downward price changes over a period of time. It expresses momentum on a scale of 0 to 100 based on the relationship between the average gain and average loss. ROC uses a simpler percentage calculation while RSI provides a normalized scale. The limitations of the ROC indicator  be mitigated by ising other indicators like moving averages, RSI, trendlines to confirm ROC signals and trend direction. Use ROC to determine the strength and sustainability of the current trend. An uptrend accompanied by increasing ROC shows momentum is accelerating and indicates the trend should continue higher.

In the second instance, while the moving averages were still bullish, the PROC indicator falls below the zero-line. Look to buy when momentum is at the weakest in the uptrend, or sell when momentum is starting to weaken. At the area marked by the square, you can see that the moving averages are aligned bullishly. As you can see in the above chart example, the PROC indicator moves within the fixed 0-line and indicates rising and falling momentum in price. This can be used as a technical oscillator to buy the dips in the uptrend or to sell the rallies in the downtrend. Another valuable aspect of the ROC indicator is its ability to identify overbought and oversold conditions in the market.

These new buy positions can be found using one of the most popular ROC signals, a zero line crossover. Traders in an uptrend will wait for the market to retrace, allowing the ROC oscillator to move below the zero line. As momentum returns with the trend buy signal may occur when ROC closes back above the zero line.

Limitations of the ROC Indicator

While it might look easy in hindsight, it is important to note that the ROC oscillator will be difficult to pick up the tops and bottoms or in other words, rising and falling momentum in price. The volatility of the price of the asset being analyzed is of course of utmost importance. Using too small a number can lead to very choppy readings while using a higher configuration setting could potentially smooth the ROC to the point that signals can be very delayed.

Crossing above the centerline generates a buy signal, as it shows upside momentum is accelerating. Crossing below the centerline generates a sell signal, indicating downside momentum is intensifying.

The “n” value has a great impact on how often the indicator crosses the centerline. Smaller values often result in more frequent crossovers or signal an early trend change. The rate of change is plotted in a separate window below the price chart.

ROC’s long history and continued popularity show that momentum is a key factor driving price changes in the market. By measuring the rate of change, ROC helps traders anticipate when trends may start or end. The ROC indicator fluctuates around the zero line, with positive values indicating bullish momentum and negative values suggesting bearish momentum.

These standard levels provide an easier interpretation of when a security may have become overextended. Its readings need to be analyzed relative to historical values to determine when momentum may have become extreme. This requires visual assessment and comparison to determine when a reversal could be signaled.

What Is Rate of Change (ROC)?

While ROC focuses purely on price changes, MACD’s use of moving averages makes it less sensitive to sudden price changes. Due to the aforementioned limitations, ROC signals often need confirmation from other indicators or tools to increase reliability. Solely relying on ROC for trading decisions could lead to misinterpretations and potential losses.

A positive ROC indicates an upward momentum, while a negative ROC suggests downward momentum.
