Rising in an uptrend and falling in a downtrend, the ROC shows momentum is strengthening. The ROC indicator works with stock indexes to confirm the prevailing trend. The ROC indicator is also useful in forex markets. Enter a trade in the direction of the ROC breakout in anticipation of the price also moving out of its range. This indicates momentum is building up and the price could soon break out of its range. A downtrend with falling ROC indicates momentum is slowing and the trend could soon reverse higher.
- The ROC indicator is also useful in forex markets.
- Look for reversals when the price makes a new high/low but ROC does not.
- Enter a trade in the direction of the ROC breakout in anticipation of the price also moving out of its range.
- •RSI also highlights divergences, but it clearly shows when it is in overbought or oversold territory based on its scale.
- The main decision for traders using ROC is picking the appropriate lookback period (n).
What Is the Rate of Change Indicator?
The divergence between ROC and price also signals a trend reversal. ROC above the centerline indicates that prices are gaining momentum and the trend is getting stronger. It calculates the speed and acceleration at which prices are rising or falling to determine momentum and trend strength.
We and our partners process data to provide:
They also provide meaningful percentage calculations as opposed to simple averages provided by moving averages. Confirm trend strength by looking for the ROC to make higher swing highs or lower swing lows. Watch for divergences between the commodity price and ROC. Look for the ROC to make higher swing highs or lower swing lows to confirm the trend. Look for the ROC to break above a previous swing high in an uptrend or below a previous swing low in a downtrend.
- Rate of Change (ROC) is obviously closely tied to price.
- Learn how to use the rate of change indicator in your automated trading strategies.
- The plot forms an oscillator that fluctuates above and below the zero line as the rate of change moves from positive to negative.
It detects even small changes in momentum, and it signals a reversal that does not materialize. The Relative Strength Index (RSI) measures price momentum and speed of recent price changes to identify overbought or oversold conditions, oscillating between 0 and 100. Look for reversals or loss of momentum based on the ROC flattening or moving in the opposite direction of the trend. When ROC starts moving in the opposite direction, it often signals a trend reversal. Commodity markets also exhibit strong trends, so the ROC indicator is helpful in gauging trend strength and reversals. In a downtrend, a falling ROC confirms the trend and signals momentum is strengthening, indicating shorting opportunities.
Divergence Signals
ROC works best when combined with other indicators. The chart uploaded below signifies how ROC reacts from extreme points to generate trading opportunities. High ROC levels indicate an uptrend may be overextended, while low ROC levels signify a downtrend may have become overdone.
ON STOCKCHARTS
The price is moving within a trading range indicates that the ROC indicator is used to spot trading range breakouts. When ROC crosses above a previous swing high, it signals momentum has strengthened and indicates an acceleration of the trend. Similarly, when the price makes a new low but the ROC fails to make a new low, it indicates momentum is strengthening and signals the correction may soon end.

The next overbought reading did not occur until April, when the Rate-of-Change again exceeded +10%. The late December high occurred with an overbought reading above +10%. Chart 4 shows Microsoft (MSFT) in a downtrend from November 2007 until March 2009.
When the price is consolidating, the ROC will hover near zero. A positive ROC can confirm a bullish trend, while a negative ROC indicates a bearish one. In this instance, the formula uses the current value of a stock or index and divides it by the value from an earlier period. In finance, the calculation for ROC can also be computed as a return over time. Conversely, a security is more likely to decline if it has an ROC that falls below its moving average or one that has a low or negative ROC. Using the ROC with other indicators can be a leading indicator.
Watch how it behaves with your favorite trading pairs or stocks. Start by adding the ROC to your charts with a 14-day setting. The ROC works best when you use it alongside other tools and your own market knowledge. By watching for zero-line crossovers, divergences, and extreme readings, you can spot potential turning points in the market. For example, if a stock is rising but the ROC is dropping, the uptrend might be slowing down. If a stock hits new highs but the ROC is lower than before, the uptrend may be losing steam.
The Price Rate of Change Indicator
A 10-day EMA was used because it is faster than a 10-day SMA. Furthermore, the 20-day Rate-of-Change is shown with a 5-day SMA to smooth out the fluctuations. Chart 5 shows Abercrombie & Fitch (ANF) within a trading range from October 2006 to February 2008. The next overbought reading occurred in early August 2008.
If we were to calculate this value for each day in a series and plot the results, we would generate the complete ROC indicator line. A trader should consider their holding period and trading style when making the decision. (Most trading platforms include ROC among their standard indicators.)
Indexes cover a basket of stocks, so the ROC captures broad momentum changes in the overall market or industry groups. Stocks often experience strong momentum shifts, so the ROC is useful for spotting trend changes. This indicates weakening momentum and a potential trend reversal. Look for reversals when the price makes a new high/low but ROC does not. The Rate of Change (ROC) indicator is effective in different trading markets. A very low negative ROC reading signifies an oversold market where the price fell too rapidly, indicating a relief rally may start.
But for passive investors, it likely generates too many signals and could lead to overtrading. This makes it very responsive to short-term momentum shifts and turns. This ability to spot momentum changes makes it a leading indicator. The ROC measures momentum and acceleration in price changes. This provides more context and confirms when both short and long-term momentum are aligned. For the best analysis, the ROC should be used on multiple timeframes simultaneously, from short to long term.
For example, rising 10-day ROC combined with rising 20-day ROC shows an uptrend with strong, accelerating momentum. Divergence between price and ROC can also signal an impending reversal. When ROC crosses above/below zero, it generates a buy/sell signal respectively as momentum changes direction. The resulting ROC value indicates the percentage increase or decrease in price over that time period.
Overbought/Oversold Extremes
Extremely high ROC readings signify an overbought market where the price rose too quickly, indicating a correction is likely. The ROC indicator is also helpful in identifying overbought and oversold levels. The price is making a new high/low but ROC does not indicate weakening momentum and a reversal could be forming. The ROC indicator is also used in spotting reversals. ROC also spot potential trend reversals in advance. For overbought/oversold levels, watch for ROC higher than +50-70% (for uptrend) or lower than % (for downtrend).
Take the closing price for the current period and subtract the rate of change indicator closing price for the previous time period. So the 10-day ROC is 20%, indicating the price has gained momentum by rising 20% over the past 10 days. The ROC indicator is calculated by comparing the current price of a financial asset to its price a specified number of periods ago. This signals an opportunity to sell short or close long positions.
