How To Create Custom Indicator MT4

MetaTrader 4 (MT4) is one of the most popular trading platforms used by traders across the globe. It offers a wide range of technical analysis tools, including customizable indicators. These indicators are essential in helping traders analyze price movements, identify trends, and make informed trading decisions.

While MT4 comes with a vast array of built-in indicators, some traders prefer to create their own custom indicators. This allows them to fine-tune their trading strategies and gain an edge in the market. In this article, we’ll take a look at the steps involved in creating custom indicators on MT4.

Step 1: Understand the Basics of MT4 Indicators

Before you start creating custom indicators, it’s essential to understand the basics of how indicators work on the MT4 platform. An indicator is a mathematical calculation based on price and/or volume data that appears on a chart. MT4 has three types of indicators:

  1. Trend Indicators: These indicators help traders identify the direction of a trend. Examples include Moving Averages and Bollinger Bands.
  2. Oscillators: These indicators help traders identify overbought or oversold conditions in the market. Examples include Relative Strength Index (RSI) and Stochastic.
  3. Volume Indicators: These indicators help traders determine the strength of a trend by analyzing trading volume. Examples include On-Balance Volume (OBV) and Volume Price Trend (VPT).

Step 2: Determine the Type of Indicator You Want to Create

Once you understand the basics of MT4 indicators, you need to determine the type of indicator you want to create. This will depend on your trading strategy and the information you want to analyze. Some popular custom indicators include:

  1. Pivot Point Indicator: This indicator helps traders identify support and resistance levels.
  2. Moving Average Crossover Indicator: This indicator helps traders identify when a short-term moving average crosses above or below a long-term moving average.
  3. MACD Divergence Indicator: This indicator helps traders identify when the Moving Average Convergence Divergence (MACD) indicator diverges from price action.

Step 3: Write the Indicator Code

Once you’ve determined the type of indicator you want to create, it’s time to write the code. MT4 uses a programming language called MetaQuotes Language 4 (MQL4) for coding indicators.

Step 4: Compile the Indicator

Once you’ve written the code, you need to compile the indicator. To do this, open the MetaEditor within the MT4 platform and select “New” to create a new script. Copy and paste the code into the editor, save the file, and then click on “Compile” to generate the indicator.

Step 5: Add the Indicator to MT4

Once you’ve compiled the indicator, you need to add it to MT4. To do this, go to the “Navigator” panel on the left-hand side of the platform and select “Custom Indicators.” Then, right-click and select “Refresh” to load the newly compiled indicator. You can now find the indicator in the “Custom Indicators” folder.

Step 6: Apply the Indicator to a Chart

To apply the newly created indicator to a chart, simply drag and drop it from the “Custom Indicators” folder onto the chart. You can then adjust the settings of the indicator as needed by right-clicking on the chart and selecting “Indicator List.” From there, select the indicator and click on “Edit” to adjust the settings.

Step 7: Test the Indicator

Once you’ve applied the indicator to a chart, it’s time to test it. You can do this by backtesting the indicator on historical data or by using it in real-time trading. Make sure to thoroughly test the indicator to ensure that it performs as expected and aligns with your trading strategy.

Tips for Creating Custom Indicators on MT4

Here are a few tips to keep in mind when creating custom indicators on MT4:

  1. Start with a simple indicator: If you’re new to coding indicators, start with a simple indicator and work your way up to more complex ones.
  2. Use existing code: Don’t reinvent the wheel. Use existing code as a starting point for your custom indicators.
  3. Test, test, test: Thoroughly test your indicator before using it in live trading. This will help you identify any bugs or issues with the indicator.
  4. Document your code: Documenting your code can make it easier to maintain and update in the future.


Creating custom indicators on MT4 can be a powerful tool for traders looking to fine-tune their trading strategies. By understanding the basics of MT4 indicators, determining the type of indicator you want to create, writing the indicator code, compiling the indicator, adding it to MT4, applying it to a chart, and testing it, you can create custom indicators that align with your trading strategy and help you gain an edge in the market. Keep in mind that creating custom indicators takes time and effort, so don’t rush the process and make sure to thoroughly test your indicators before using them in live trading.
