What is a trading indicator and how it helps you as a trader


Trading has to do with having the right information when needed at the right time. To grasp how prices move, traders use a trading indicator. Think of it as a helpful tool that can tell you when it's a good time to buy or sell stocks or other assets. It gives you data-driven clues about when a price might change direction, how risky a trade might be, and how strongly the market is moving. 

Whether you're a beginner or an experienced trader, using trading indicators can be valuable in pursuing your financial objectives. So, take the time to explore and integrate these tools into your trading approach for more informed and confident decision-making.  

What is a trading indicator?

Trading indicators are also known as technical indicators. A trading indicator utilises information about price volatility, mathematical equations, and trading patterns to help you generate a visual signal based on the market’s behaviour.

It is a market analysis tool that helps you determine if a market is bullish or bearish, giving you insight into future price movements for shares, stocks, commodities, foreign exchange, etc.

6 common trading indicators


What is a trading indicator and how it helps you as a trader


A trading indicator can help you to craft your strategy as a trader. Here are six of the most popular and highly effective indicators that you can use:

  1. Simple moving average (SMA)
  2. Exponential moving average (EMA)
  3. Moving average convergence divergence (MACD)
  4. Relative strength index (RSI)
  5. Stochastic oscillator
  6. On-balance volume (OBV)


1. Simple moving average (SMA)

The simple moving average is one of the most commonly used technical trading indicators. This sums up a set number of closing prices and divides the sum by the number of periods chosen. Say, for instance, the price of an asset you have traded is consistently above the SMA. This suggests an uptrend, while a consistent price below the SMA indicates a downtrend.

The SMA indicator guides you to assess whether the current price deviates significantly from the average, potentially signalling a reversal direction.

2. Exponential moving average (EMA)

Let’s briefly compare the exponential moving average and SMA for you to understand it better.

The EMA indicator focuses more on recent changes in data, especially short-term price movements. On the other hand, the SMA treats all data points within a specific time frame equally.

Since the EMA focuses on recent changes in data, it can help you spot new trends more quickly than the SMA. The EMA indicator has a shorter delay than the SMA.

Note that moving averages can guide your trades along the trend, but there might be a delay when you are deciding when to start or stop a trade.

3. Moving average convergence divergence (MACD)

MACD indicator has two parts: the MACD line and the signal line. The MACD line is derived by subtracting the longer-term EMA from the shorter-term EMA.

During an analysis, let’s say you notice that the MACD line intersects above the signal line. You can interpret that as a bullish signal as it indicates that the upward momentum might be gaining strength.

But if the MACD line goes below the signal line, it’s seen as a bearish signal, suggesting that downward pressure could increase.

4. Relative strength index (RSI)

You have probably heard of or seen this indicator in trading books or articles.

This trading indicator is a momentum oscillator used to assess the speed and magnitude of price movements.

By using this trading indicator, you can identify overbought and oversold conditions of the asset you’re trading.

It is calculated based on the average of recent price gains and losses over a specified period, typically 14 periods.

5. Stochastic oscillator

This trading indicator doesn’t track price movements or volume. Instead, it monitors the velocity or momentum of price changes.

Typically, speed changes occur before changes in price direction. These enable you to identify potential reversals through bullish and bearish divergences.

Similar to the MACD lines, the stochastic oscillator consists of two lines. One of these lines is quicker than the other, mirroring the arrangement found in the MACD indicator.

6. On-balance volume (OBV)

The on-balance volume is a trading indicator that predicts the changes in an asset's price using volume.

This indicator turns buying and selling volume in your trade into a cumulative measure by adding volume on days when prices rise and subtracting volume on days when prices fall.

The entire day's volume is labelled up-volume if your trade concludes higher than the prior close.

Conversely, if your trade ends lower than the previous close, it is categorised as down-volume.


How a trading indicator generally works


What is a trading indicator and how it helps you as a trader


Have you ever wondered about how a trading indicator works on a trading platform? How does it operate before you click the tool, and how can you use the visual signals?

Here’s a quick breakdown:

1. Trading indicators collect various types of data

It uses historical price action patterns such as open, high, low, and closing prices, and volume data. Some indicators make use of other data such as moving averages, volatility measures, or momentum.

2. Indicators execute mathematical calculations

A trading indicator uses mathematical formulas and algorithms to process the collected data and generate a numerical value or trading pattern. The calculations vary depending on the specific indicator being used.

3. It generates signals for traders to interpret

Once a trading indicator’s calculations are complete, its signals will suggest potential trends, reversals, or momentum shifts in the market based on your asset's price volatility or volume.

4. Signals are analysed

Next, you can analyse the signals in connection with other factors such as fundamental analysis, news events, and market sentiment.

5. A trading strategy then follows

As soon as you have analysed the signals of the indicators, you can now develop a trading strategy based on the indicator you used. For example, the RSI trading strategy indicates that if the market begins to turn bearish, a trader might consider selling or buying a new particular asset.

Using a trading indicator isn’t just a small part of trading. It’s a crucial step you should include to move closer to improving your chances of trading success.

  • Trading indicators provide you with objective data-driven insights that may help you avoid making emotional decisions and instead rely on quantifiable information. When you are calm, you are less likely to make common trading mistakes.
  • A trading indicator may improve your timing and consistency for executing trades and maximise capital gains.
  • Different indicators are designed to capture momentum, volatility, and trend strength. They can sharpen your analytical skills and provide a more comprehensive view of market conditions.
  • They can filter out market noise and highlight key price movements – making it easier to identify significant trends and patterns.
  • A trading indicator automates the process of analysing complex market data, saving you from manually sifting through charts and information.

But even though trading indicators can offer useful information, they should be combined with other analysis techniques and risk management plans.

Be sure to take the broad market situation and your trading objectives into account when you’re making trading choices.
