Its greatest value comes when incorporated into a comprehensive trading system that includes other forms of analysis. As with any technical indicator, the ROC should never be used in isolation. A falling ROC reading that remains in positive territory still reflects upward momentum, and vice versa.
The indicator is an unbounded momentum indicator used in technical analysis set against a zero-level midpoint. Traders can also pay close attention to the speed at which one price changes relative to another. It can also be used in finance and investing to describe the change in the value of an asset or index over time. Graphically, the rate of change is represented by the slope of a line. ROC is often used by analysts when discussing momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another.
Who invented ROC indicator?
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.
- Because of this, ROC can sometimes appear to be unbalanced.
- Momentum oscillators are ideally suited for sideways price action with regular fluctuations.
- ROC crossing above centerline, indicates upside momentum is accelerating and a new uptrend may be starting.
- If the current price is greater than the previous price, the ROC increases.
- Rate of change is a technical indicator of momentum that measures the percentage change in price from period to period.
ROC crossing below zero indicates downside momentum is accelerating and entering a sell position could be considered. The ROC crossing above zero indicates upside momentum is accelerating and entering a buy position could be considered. The ROC indicator is also used to spot crossovers at the zero line. Look for divergences between the price and the ROC. Look at the ROC during previous price swings to identify important highs and lows. Price keeps falling but ROC begins rising signifies downside momentum is weakening and a rebound could be approaching.
It is used primarily to identify overbought and oversold conditions, but some analysts use it to confirm trends and identify possible reversals. Short-term overbought signals were ignored because the bigger trend was up. For example, if price makes a higher high but ROC makes a lower high, it signals weakening momentum and the potential for a reversal.
How does the Rate of Change (ROC) Indicator used in Trading?
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 it crosses below zero, it indicates price momentum is decelerating and signals a sell.
- Look for the ROC to make higher swing highs or lower swing lows to confirm the trend.
- A positive ROC can confirm a bullish trend, while a negative ROC indicates a bearish one.

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.
This works best in conjunction with other signals like trend strength or reversals. This signals an acceleration or deceleration of momentum and trend reversal. When ROC crosses below a previous swing low, it signals momentum has weakened and could foreshadow a trend reversal. A high negative ROC signals an oversold market where the price fell too rapidly, indicating a relief rally could soon start. A cross below zero signifies downside momentum is increasing and signals an opportunity to sell short or close long positions, as a downtrend could be beginning. Conflicting signals between time frames suggest the trend may be losing steam and a reversal is more likely.
The Price Rate of Change Indicator
A rising ROC above zero indicated increasing buying momentum while falling ROC below zero indicated increasing selling momentum; crossing over from either extreme resulted in buy and sell signals. Initially Return On Capital (ROC) was calculated using closing prices and displayed as an oscillator with its centerline set to zero. Morton Baratz invented the Rate of Change (ROC) in the late 1940s during his career as an American technical analyst who pioneered momentum indicators as an analysis method in financial markets.

Below uploaded chart is an example of how ROC can be utilized to generate market information. A ROC reading near zero shows a lack of directional momentum, while an extreme reading signifies momentum may be overstretched. ROC is an oscillator that fluctuates above and below a centerline, usually at zero.
The first was up as the 250-day Rate-of-Change was largely positive until September 2008 (1). Chart 2 shows IBM with the 250-day, 125-day, 63-day and 21-day Rate-of-Change. This can be broken down into 125 days per half year, 63 days per quarter, and 21 days per month. The blue cells show the 12-day Rate-of-Change from May 7th until May 25th.
This simple strategy helps you catch new trends early. The ROC shows up as a line below your price chart. Unlike other indicators like RSI, the ROC doesn’t have upper or lower limits. By the end, you’ll be able to add this tool to your trading toolkit with confidence. The higher this number, the more decimal points will be on the indicator’s value.
What Are Other Terms for Rate of Change?
Divide the difference by the previous period’s closing price. The indicator works well on higher time frames like Daily, weekly and monthly. An example of how crossing above or below zero line generates buy and sell signals. High volatility means the trend is becoming unstable and prone to reversal. A sudden spike in ROC upside volatility sometimes precedes a downtrend. Reversal is more likely when ROC reaches extreme overbought or oversold territory.
Extreme high or low ROC levels indicate the trend may have become overextended and is prone to reversal. An ROC reading near the centerline shows a lack of clear directional momentum. ROC below the centerline signifies that selling pressure is intensifying and the downtrend is accelerating. ROC provides useful insights into the momentum behind price moves.
Shorter look-back periods create a more sensitive ROC line while longer lookback periods create a smoother, less volatile line because more data points are used. If the current price is greater than the previous price, the ROC increases. ROC has a similar “drop-off effect” to the simple moving average because older data points are removed from the calculation and replaced with new rate of change indicator data points.

The table above shows the 12-day Rate-of-Change calculations for the Dow Industrials in May 2010. Strike, founded in 2023, is an Indian stock market analytical tool. Stay informed with Strike’s guide on in-depth stock market topic exploration. Used together, ROC and RSI provide both confirmation and warning of when trends are strong or ready to reverse. This makes divergences easier to identify with RSI compared to visually spotting loss of momentum with ROC. The effectiveness of any indicator depends on several factors.
The distance of the ROC from the centerline represents how strong the momentum is rising or falling. It was one of the first momentum oscillators created for analyzing price charts. The ROC indicator was developed in the late 1940s by market technician Morton Baratz. ROC oscillates above and below a centerline at zero.Readings above zero indicate bullish momentum, while readings below zero indicate bearish momentum. Rate of change (ROC) is an important concept that tells us not just that things are changing, but how fast things are changing.
