The Rate of Change (ROC) is a price-based indicator designed to measure the rate at which the price changes from one period to another. The measure of the current price in relation to a defined look-back period is the typical rate of change definition. However, when expressed as a percentage, ROC can help traders determine not only momentum, but also overbought and oversold conditions as well as the trend direction. ROC is a momentum oscillator; other indicator types similar to ROC include MACD, RSI and ADX. Any financial asset can theoretically advance indefinitely, but the maximum drop is to zero. This essentially means that while negative ROC values have a limit, positive ROC values are unbounded.
ROC is calculated in such a manner that traders can assess how the price has changed compared to a defined look-back period. The rate of change formula is as described below:
ROC = [(Current Close – Close n periods ago) / (Close n periods ago)] X 100
*Where ‘n’ is a ‘user’ defined number representing the number of periods ago that the price is being compared to.
The default ‘n’ on most platforms is 14, but 9 and 25 are also common among many traders. In many cases, longer-term traders usually select a period as large as 200. While a smaller number will react to prices faster, it may lead to choppy or false signals. On the other hand, a larger number will react slowly to price changes (the ROC will be smoother), but this may lead to more reliable signals when they occur. It is important to understand the volatility nature of the underlying asset to be analysed. As well, traders can also use shorter ‘n’ values on higher timeframe charts, such as daily and above; and longer ‘n’ values on lower timeframe charts, such as 1 hour and below.
Reading the ROC Indicator
With ROC seeking to compare prices from a past defined period, the indicator values will either be above zero or below it. Zero will act as the centreline. When indicator values hover around zero, it will denote a consolidating market. A reading above zero will imply a bullish sentiment in the market; whereas a reading below zero will imply a bearish sentiment in the market. Although used as an oscillator, the ROC has no defined overbought and oversold levels. Traders pick out such zones by observing the prior extreme levels the ROC printed in relation to the price of the underlying asset.
ROC and Momentum
ROC and momentum are two different indicators designed to help traders decipher a similar price element – momentum. Both indicators tell a similar story and can be used interchangeably. The main difference between the two lies in their calculation. ROC values are expressed as a percentage, while Momentum Indicator values are absolute values. Also, ROC has 0 as the centreline, while the Momentum Indicator has 100 as the centreline. Other technical analysis tools that help traders decipher momentum information include MACD, RSI and ADX. MACD traders watch out for its histogram to determine price momentum. A rising slope of the histogram denotes increasing bullish momentum, while a falling slope implies increasing bearish momentum. RSI has a centreline at 50; a cross above 50 indicates that an uptrend is gaining momentum, whereas a cross below 50 indicates that the prevailing downtrend is more momentous. ADX is a non-directional momentum indicator that quantifies trends. ADX prints values of between 0-100; with values above 25 indicating that the prevailing trend is gaining momentum, whereas values below 25 show that the prevailing trend is weak.
Using ROC in Trading
Here is how to trade the signals generated by the ROC indicator:
- Overbought and Oversold Conditions
Momentum indicators are particularly ideal for trading ranging markets because they help forecast turning points accurately. Momentum generally refers to a trend continuing its course, and in a ranging market, if a trend starts to lose momentum, it is best to start looking for opportunities to trade in the opposite direction. Peaks and troughs can occur after a certain time has elapsed or when a certain percentage move has been made. As an unbound indicator, ROC gives a clear picture of when to anticipate such turnarounds based on previous printed indicator levels.
Breakouts occur with strong momentum, and what better indicator to qualify breakouts than the ROC. When the price is consolidating or ranging, ROC will print flat values. A sustained sharp rise or fall will confirm that the breakout trend will be sustained going forward.
- Zero Line Crosses
A zero-line cross on the ROC is an indication that a new trend is forming. A cross of the zero-line from below indicates that a bull trend is now in place, whereas a cross from above indicates that a downtrend is now in place. As mentioned above, it is important to consider the asset volatility and timeframe chart to minimise false or whipsaw ROC signals that come from zero-line crosses.
Divergences are great for timing market turning points, and with the ROC being a momentum indicator, it can deliver accurate and compelling divergence signals. Bullish divergence will occur when the price is forming lower lows, but the ROC is printing higher lows. This will be a signal that the downtrend lacks momentum and a trend change to the upside is about to occur. Similarly, a bearish divergence will occur when the price is forming higher highs, but the ROC is printing lower highs. This will be a signal that the uptrend lacks momentum and a trend change to the downside is about to occur. It is important to note that sometimes, a divergence signal may take a little longer to play out, and it is important to seek confirmation from other tools or even price candlesticks to identify optimal trade entry points.
ROC and Other Technical Analysis Tools
As pointed out above, ROC may sometimes deliver early or late signals. It is, therefore, important to seek effective indicator combinations with the ROC that will help generate confluence signals.
Here are some of the best ROC indicator combinations strategies:
- ROC and Stochastics
This combination is best for timing trend reversals. When the ROC delivers a divergence signal, traders can watch out for stochastic crosses in overbought or oversold zones to pick out optimal entry points in anticipation of a trend change. For instance, in the case of a bullish divergence, the best entry point would be a stochastic cross in oversold territory.
- ROC and Moving Averages
The ROC zero-line cross can sometimes deliver vague signals to confirm a trend change. To confirm trend reversals, traders can combine the ROC with two moving averages. For instance, when the ROC has just crossed the zero-line from above to signal a downtrend, additional confirmation will be received when the faster-moving average crosses the slower moving average downwards.
Main ROC Trading Strategies FAQ
- What is the ROC indicator?The ROC indicator is shorthand for Price Rate of Change Indicator. It is a momentum based indicator that measure the percentage change in price, thus giving traders insight into how rapidly price is rising or falling. The obvious takeaway is that the faster price is changing the stronger the momentum of the trend. The indicator is commonly used to spot overbought and oversold conditions, divergences, and centerline crossovers. Because the indicator is prone to whipsaws it is best used as a confirming indicator.
- How to trade with ROC Indicator strategy?Since the ROC indicator is a momentum indicator displayed as a histogram it is very easy to read and interpret. When it is above zero it shows upward price momentum, and when it is below zero it indicates downward price momentum. The further away from zero the indicator moves, the stronger the momentum of the price move. Traders can use this information either to confirm trend changes, or to inform them when a trend is gaining or losing momentum. The ROC is considered to be a confirming indicator and is typically used in conjunction with other indicators.
- How do you read the ROC Indicator?The ROC Indicator is typically used to confirm price moves or detect divergences, as well as being used to determine when markets are overbought or oversold. Reading the ROC indicator is fairly simple. When it is above the zero line and moving higher it indicates the trend is getting stronger. However if it rises too far, say to the +3 level, that could indicate an overbought market. If it is falling back towards the zero line it indicates slowing momentum and a potential change in trend. The same is true but reversed when the indicator is below zero.
