ROC Trading Strategy | How to Measure Changes in Trend Speed


Table of Contents

ROC trading actually implements two concepts that study trend strength and possible teleportation. At the end of this inventory guide, you learned how to trade ROC metrics as a standalone system. You need to be able to react very quickly to constant and rapid stock price fluctuations. However, it’s a good idea to objectively figure out where the stock market is going. This objective view comes from what is called the rate of change (ROC).

As you know, the real market environment is very dynamic and you need to adapt to constantly changing market conditions. This is why we use our ROC trading strategy to give you the best signals and starting points for buying and selling.

What is the ROC (Rate of Change) indicator?

Rate of Change (ROC) is a momentum-based technical indicator that measures the rate of change in price between the current price and the price over a period of time. The ROC indicator is displayed as relatively zero, whereas the indicator moves to the positive range when price fluctuations occur and to the negative range when the price falls.

This indicator can be used to identify deviations, overthinking and reversing conditions, and focal intersections. ROC stands for Rate of Change (ROC), a technical indicator that is part of a suite of momentum-based indicators. The ROC Oscillator measures the percentage change in the current price and the price of N over a period of time. In other words, the rate of change tells you how fast the current price is moving compared to last week compared to yesterday or last month. You can simply see the ROC indicator as a speed indicator. The concept of rate of change (ROC) mainly measures two things:

  1. When a change in momentum occurs.
  2. Strengths and weaknesses tendencies.

Combining these two principles can help you find great reverse trading opportunities. The ROC indicator fluctuates above and below the midpoint of the zero levels. Positive ROC values ​​usually identify a bullish trend, and negative ROC values ​​usually identify a bearish trend.

It is important to understand that stocks can only fall 100% in theory. Therefore, the lower ROC limit is -100. Ten dollar shares traded on the New York Stock Exchange (NYSE) can go up to $0 and cannot be negative. However, the same $10 stock can go up to $50, $100, or $1,000.

In theory, there is no upper limit on how much a stock can go up.

As a result, there is no upper ROC limit.

To sum up:

  • ROC lower limit = -100%.
  • Upper ROC = infinity.

I will show you how to calculate the ROC and how to compile the ROC indicator on the price chart.

How to calculate the rate of change indicator

The main step in calculating ROC is to choose the “n” value. Short-term traders can choose a small value (e.g. 9) for n. Long-term investors can choose a value such as 200. The value of N is several periods ago when comparing current prices. The lower the ROC value, the faster it reacts to price fluctuations, but this can also mean more false signals. The higher the value, the slower the ROC will respond, but it can be more important when the signal occurs.

Choose a value for n. It can be about 12, 25, or 200. Short-term traders tend to use lower numbers, while long-term investors use larger numbers.

  • Find the latest closing price.
  • Find the closing price for the n previous periods.
  • Enter the prices from steps 2 and 3 into the ROC formula.
  • At the end of each period, calculate the value of the new ROC.

The Formula for calculating the rate of change (ROC)

The formula for the ROC indicator is as follows:

ROC = [(Closing price-closing price before period N) / Closing price before period N] x100


  • Close = Last Day or Last Close.
  • Close Price Before N Period = N value represents multiple periods after the current price has been compared.

By default, the number of periods for calculating ROC is 9 periods. The 9-tier ROC indicator is more suitable for short-term trading. For long-term trading, stock traders must choose a larger time frame, such as 50 100 or even 200 for long-term real investors.

The multiplier of 100 is used at the end of the price level indicator formula to convert the result to a percentage.

Now that you know what the ROC formula is, let’s see how to trade the ROC indicator.

Below, we will show you some of the most popular ways traders use ROC on the stock market.



How do you trade ROC indicators?

In short, the ROC indicator moves with the price. If the stock price rises compared to the previous N period, the ROC is positive. Conversely, if the stock price falls compared to the previous N period, the ROC will be negative.

The ROC oscillator collapses (rises) with the stock price. At the same time, the faster the stock price declines (increased), the lower (stronger) the stock price declines (increased).

As soon as the rate of reduction (rate of change) decreases, the ROC reaches the lower limit and the negative ROC value decreases. When a stock falls, the stock’s ROC value starts to rise because the stock no longer collapses.

If the stock price rises slightly, the ROC value will be positive depending on how long ago (a few years ago) the ROC was calculated. As the ROC rate increases, the stock price will rise faster as well.

And as the stock approaches the peak, the ROC oscillator will collapse again as the price change slows down. In short, here’s how to interpret ROC behavior.

Here is a brief summary of how to trade ROC indicators for beginners.

  • A sharp rise in ROC shows that the stock is rising faster.
  • A sharp decline in ROC indicates a faster decline in stock prices.
  • If ROC fluctuates above and below the zero limits, those prices may be consolidated.
  • Crossing the zero line ROC may indicate a change in the current trend.

As ROC metrics tend to convert quickly, your conversion strategy can be a bit riskier.

ROC indicators can give us overthinking and exaggerated signals. However, without a strong ROC trading strategy, overthinking and exceeding ROC signals are not as accurate as RSI indicators or probabilistic indicator signals.

Another less common use of the RSI indicator is trading conversion signals.

The ROC conversion signal occurs when the stock price moves in one direction and the ROC oscillator moves in the opposite direction.

Why buy ROC?

You may be wondering why you should use the RSI oscillator, the Williams %R indicator, or any other non-oscillator ROC. Although these measurements are not mutually exclusive, it is important to understand the unique characteristics of each.

First, ROC is a major oscillator that can be used to identify high momentum stocks that will typically outpace the market in the short term. Choosing ROC stocks allows you to buy quality stocks for a positive return. Some inventory screeners can track ROC inventory and set up rate-of-change alert notifications.

The wrap-up

Breaking the trend and studying its movement reveals that the rate of change or the rate at which the trend is moving is changing. The basic idea is to use ROC metrics to identify areas where the market is starting to slow down or accelerate. The pace of change can tell you how strong buyers and sellers are in the market.

Let’s take a look at how to trade with ROC indicators along with other technical indicators.



ROC trading strategy

This ROC trading strategy helps everyone learn how to trade with a volatility indicator to predict future stock price movements.

We don’t want to discriminate against a particular trading style.

So, to make everyone happy, I’ll explain two approaches.

  1. ROC trading strategy for short-term traders (Scalpers and day traders).
  2. ROC trading for long-term investments in stocks.

First, let’s think about long-term stock investors.

ROC Trading and long-term investment in stocks

It’s no secret that the momentum oscillator is the day trader’s best friend. However, the ROC indicator is a good tool for long-term equity investments. Trading on long-term stock charts delays changes in market sentiment. So you are inevitably late to the party.

To avoid this pitfall, you need to analyze trends over multiple time frames. There are 250 trading days per year, which can be divided into:

  • 125 trading days in 6 months.
  • 63 trading days per quarter.

A transaction on the 21st of the month.

Of course, the trend reversal occurs first, appears on a lower schedule, and gradually moves to a different schedule. Now there is a way to see the initial changes in market development.

If 250 ROC and 125 ROC are positive, the long-term trend is bullish. At the same time, it can be seen that the shortest period (ROC-21) will lead to many sharp bends due to the ebb and flow of the market.

Rule of thumb: We use two schedules to check for a trend reversal.

In this case, you want to set 21 ROCs and 63 ROCs to negative to identify handicap changes early. If it’s still below zero, the ROC of the intervals 125 and 250 should also actually be negative to see the trend change.

Short-term ROC trading

It also displays a 40-year sliding period to determine the overall intraday trend. If the slope of the moving average rises, you can see that the overall trend of the stock is rising.

When Tesla’s share price rises, you can see that its ROC fell just below zero. On an uptrend, when the ROC leaves the negative zone and moves above zero, Tesla’s price will drop, giving you a great buying opportunity.

The 20-year moving average is designed to avoid major problems and potentially large losses. This is another application of the 20-year moving average along with the ROC indicator. The flattening of the moving average indicates that the market is in a consolidated position and the ROC will inevitably strive for zero levels. This means that the ROC crosses back and forth at the zero levels, resulting in a lot of false signals.

In this market scenario, it’s best to look for other stocks that aren’t out of the way and are clearly trending.


What is the ROC indicator?

The rate of change (ROC) is a technical indicator of speed.

It measures the rate of change in price between the current price and the price before a certain period. This indicator is displayed based on zero, and the indicator moves to the positive range when a price change occurs and moves to the negative area when the price decreases.

ROC indicator calculation:

Track the relationship between the closing price over the two periods. In standard calculations, the period is 12 days.

The 12-day closing price is taken into account and deducted from the current closing price.

Differences are expressed or used as ROC.

Sometimes it can be positive and sometimes negative.

ROC = [(nearly before episode) / (nearly backward period)] * ​​100

Therefore, the center baseline is displayed as 0.

Trading rules and interpretation:

  1. If the ROC is above the zero lines and continues to rise, it indicates not only the trend is rising, but the rate of rising is also accelerating.
  2. If the rate of change crosses the zero line, but decreases, it indicates that the uptrend is slowing.
  3. If the rate of change is above zero and starts to increase again and crosses the previous high, it indicates that the trend is highly dependent on speed.
  4. The rate of change is less than the zero lines, but a decrease indicates that the rate of decrease increases.
  5. If the rate of change is less than zero but starts to rise, it indicates that the rate of decline is slowing.
  6. If the rate of change is less than zero and starts to decrease, it means that the rate of decrease has increased again.

Trading strategy using ROC indicators

ROC is a very simple strategy that shows positive momentum whenever the rate of change rises above the zero lines from the bottom and whenever the ROC goes down the zero lines with respect to r-top. This creates negative price dynamics.

However, you can include a moving average to generate a stronger signal. It uses a combination of 5 and 30 moving averages and ROC to carry out the transaction.

When the ROC rises above the 0 line

Case 1: When the ROC rises above the 0 lines, you take a long position at 410, and when the rate of change below the 0 line drops to 440 (approximately), you gain 30 points.

Case 2: When ROC rises above the zero lines and five DMAs exceed 30DMA, a buy signal is generated again at 445-450 (approximately), and when the rate of change falls below the zero lines, the output is 555-560. …

Case 3: Then, when ROC falls below the zero lines and 5DMA falls below 30DMA at 550, a sale signal is generated. Here “R.

Case 3: Then, when ROC falls below the zero lines and 5DMA falls below 30DMA at 550, a sale signal is generated. This position is squared to 440 when the rate of change rises above the zero lines.

ROC limit:

A potential problem with using the ROC metric is that it gives more weight to determine future price movements, but gives recent prices the same weight as the price they received some time ago.

Indicators tend to rotate quickly, especially around the zero lines.

ROC deviations sometimes give false signals, so traders need to confirm the trade if there are other inverse signals and other analysis methods of the indicator.

Conclusion ROC trading

Therefore, ROC trading is about discovering changes in the momentum of the stock price. As with all technical indicators, it is advisable to supplement the ROC indicator with other equipment. It is important to remember that ROC indicators have their own limitations and for this reason, the ROC trading strategies presented in this guide combine trading methods or other technical indicators.

Here is a summary of what we learned:

  • ROC refers to how fast the price moves compared to the previous period.
  • The upper ROC range is unlimited and the lower range is limited to -100.
  • ROC goes up and down with the price.
  • Stock prices are consolidated when ROC fluctuates around zero.
  • ROC indicator is good for inventory collection.
  • For long-term investments, analyze trends across time scales.

ROC monitors whether the trend rate increases decreases, or maintains the same rate. If the rate of change is higher than the zero lines but decreasing, it indicates that the uptrend is slowing.

When the rate of change is above zero and starts to rise again and crosses the previous peak, the increase shows that it is highly dependent on speed. ROC is a very simple strategy that means a positive rate whenever the rate of change exceeds the zero line. Few traders use ROC to identify extremes and predict turning points.
