How to Use the Rate of Change Indicator to Uncover Momentum Secrets in Market Prices

Rate of Change (ROC) indicators can be an extremely powerful resource for investors. Securities with positive ROC indicators tend to outshone their market peers over short time horizons.

The Relative Order Condition Index, or ROC, measures the difference between current price and its previous level over a given time interval. Often placed against zero, an increasing ROC indicates an uptrend while decreasing ones indicate downward ones.

Identifying Trends

The ROC Indicator is an effective momentum tool designed to assist traders in identifying market trends. It employs a simple calculation to compare current price with price of prior period; any difference is displayed as a percentage difference and displayed visually on screen. This method makes the indicator more reliable than similar momentum indicators that use different formulas and methodologies, rendering results less accurate.

This indicator can be used to detect price momentum changes, including when trends change direction or reverse. Furthermore, the ROC can also be used to detect overbought and oversold conditions without experiencing whipsaws – unlike its rival momentum indicators such as Relative Strength Index (RSI). Unfortunately it does not provide clear definition of overbought/oversold zones so traders will need to manually define these zones on their chart themselves.

If the indicator line moves away from zero level, this indicates a market is moving into a downward trend and should be followed by a significant decline in price of security (confirming it ). Conversely, when it moves above the zero line it signifies the opposite trend and confirms it as such.

Another method of detecting trends is analyzing an indicator’s value over multiple periods. If an overbought indicator persists for extended periods, this suggests the trend could soon reverse itself and traders should anticipate price reversals to enter short positions.

Traders can adjust their return-on-capital (ROC) by choosing an “n” value; shorter-term investors might select a smaller value, while those planning long-term investments might opt for larger ones. Once this parameter has been set, an investor can examine its history to spot patterns within its ROC history.

Dependent upon the value chosen, ROC indicators provide rare but accurate signals. However, it is wise to avoid trading during key news or economic data releases, which could significantly impact price movements quickly.


When the ROC line moves upward, this indicates a positive trend with buyers gaining momentum and buyers increasing purchases. When values decrease however, sellers gain strength as bearish momentum rises – this provides another confirmation signal and helps traders identify overbought/oversold zones more accurately.

The ROC indicator does have some drawbacks that traders should be wary of. One significant problem is its extreme sensitivity to price changes; since its values do not average out over time, sudden price surges or sharp reversals may cause drastic fluctuations in its values; although this effect can be partially counteracted by setting an extended calculation period.

One major drawback of indicators is their tendency for whipsawing on short-term time frames, an effect caused by their centerline crossings being determined using an approximate calculation formula that may give misleading signals when calculation periods become shorter.

Traders can lessen the negative impacts of such drawbacks by employing longer calculation periods or applying additional filters to an indicator’s values – both will reduce its effects while simultaneously improving accuracy of its signals.

Additionally, it is wise to combine the ROC indicator with other tools, such as Stochastics or Relative Strength Index (RSI), for maximum effect. Together they will help identify and confirm trends while pinpointing entry points for trades.

Additionally, traders should avoid trading around key economic data releases and news events as these can have a dramatic effect on price in the short-term. An indicator could give false signals and lead to losses; to minimize this risk and ensure more profitable trades wait for market stability before trading again.


As the ROC indicator can generate false signals around its zero line, traders should avoid trading simply because an indicator line reaches an overbought or oversold level. Instead, traders should rely on additional reversal indicators and analysis methods to confirm these signals before acting upon them.

When the Relative Odds Ratio (ROC) line climbs and crosses over into positive territory, market participants have shown they are optimistic about an asset and that its price should increase in the near future. On the contrary, when the ROC line drops below zero it indicates market participants’ loss of optimism for it and suggests its price may drop in the near future.

To calculate Return On Capital (ROC), traders use a formula that compares the current asset price with its price from “n” periods ago. This number can be selected at random; long-term traders might select 100-200 days while shorter term traders might opt for 5-10-20 periods as their measure.

ROC (Risk Of Change) is a momentum indicator used to track price changes quickly and predict where they might head in subsequent periods. Easily understood and offering ample opportunity for profits, the ROC makes an invaluable tool for both novice and seasoned traders alike.

Combine the ROC indicator with other technical analysis methods for increased success when trading. They should examine its dynamics over multiple time frames, comparing it with that seen over longer-term time frames; if these patterns match up strongly this serves as confirmation that other indicators or analysis methods have produced valid signals.

Consideration should be given to an asset’s volatility when selecting indicator settings; this can significantly impact its resulting signal. In addition, Tuned offers an auto-scaling feature which automatically adapts the settings according to your currency pair’s volatility level.


Traders use the rate of change indicator to spot divergences, identify overbought or oversold conditions and confirm trends. It does this by comparing current price with that from an earlier timeframe (by default 9 periods back); you can easily change this value so as to match any timeframe – 9 months, weeks days or hours! Additionally, its n value plays a key role in how volatile its reading will be; small numbers produce more signals while higher ones produce fewer.

Rate of change indicators are momentum oscillators, meaning they can move either direction and be subject to whipsawing around the zero line. Therefore, these tools should only be used as filter or confirmation tools rather than primary trading signals.

To determine the Return On Capital (ROC), first identify an asset’s daily volatility. Next, choose an applicable timeframe – be it 9, 12, 25, or 200 periods; shorter-term traders often opt for lower numbers while long-term investors often go with larger ones. Finally, find the most recent price and one from an arbitrary period back and plug them into a formula: ROC = (closed – opening)/volatility

Utilising the Relative Momentum Index (ROC) indicator can be immensely valuable to traders when used alongside other indicators and analysis methods. If prices are rising while their ROC value drops, this could indicate that upward momentum has peaked and markets may reverse direction. Comparing readings on various timeframes is also important; if its value reversing within one timeframe but not another could serve as an early reversal signal.

However, traders should exercise extreme caution when using this indicator, as it can often give false signals during periods of high volatility and whipsawing around zero level. Therefore, it is necessary to use a trading system with additional filters as well as analyze multiple timeframe charts in order to achieve optimal results.
