cTrader Custom Indicators (How to Find, Install, and Use Them)
While cTrader comes with over 70 built-in indicators, you can extend its capabilities with custom indicators created by the community. These are written in C# using the cTrader Algo development environment. In this guide, we explain how to find, install, and use custom indicators on cTrader.

What are custom indicators on cTrader
A custom indicator on cTrader is a program written in C# that adds extra visual information to your chart. Like on other platforms, custom indicators do not place trades. They only display data such as lines, zones, arrows, or other visual elements to help with your analysis.
Because cTrader uses C#, a modern and widely-used programming language, custom indicators can leverage the full power of the .NET framework. This means they can be quite sophisticated in their calculations and visual output.
Where to find cTrader custom indicators
cTrader Marketplace. The official cTrader website hosts a marketplace where developers share free and paid indicators. Each listing includes a description, screenshots, and sometimes source code. This is the safest and most reliable source.
cTDN (cTrader Developer Network). This is the official developer community where members share code, ask questions, and collaborate. You can find many free indicators here along with documentation and tutorials.
Trading forums and communities. Some forex forums have dedicated cTrader sections where traders share custom indicators. The community is smaller than MetaTrader's, but the quality of shared tools is often high.
Freelance developers. You can hire a C# developer to build custom indicators based on your specifications. Since C# is a mainstream language, finding qualified developers is not difficult.
Installing custom indicators on cTrader is straightforward
- Download the indicator file. It will typically be an .algo file or a .cs (C# source code) file.
- Open cTrader and navigate to cTrader Algo (you can access this from the left sidebar or the bottom panel).
- In the cTrader Algo section, find the Indicators folder.
- If you have an .algo file, double-click it and cTrader will install it automatically.
- If you have a .cs file, copy it into the Indicators source folder, then open it in the cTrader Algo code editor and click Build to compile it.
- Once installed, the indicator appears in your indicators list and can be dragged onto any chart.
The cTrader Algo development environment
cTrader Algo (formerly called cAlgo) is cTrader's built-in development environment. It is where you create, edit, compile, and manage custom indicators and cBots.
Key features of cTrader Algo
- Code editor with syntax highlighting, auto-complete, and error detection
- Built-in compiler that turns your C# code into a working indicator
- Debugging tools for finding and fixing problems
- Access to the .NET framework for advanced programming
- Template projects to help you get started quickly
Even if you have never programmed before, cTrader Algo provides a gentle introduction. You can start by examining the source code of existing indicators to understand how they work, then make small modifications before building your own from scratch.
Configuring custom indicators
When you add a custom indicator to a chart, a settings panel appears where you can adjust its parameters.
- Input values like periods, multipliers, and calculation methods
- Visual settings like colors, line styles, and widths
- Display options like which timeframes to show the indicator on
Each indicator has its own set of configurable inputs defined by the developer.
Building your own indicators
If you know C# or want to learn, building your own indicators on cTrader is a rewarding experience.
- Open cTrader Algo and create a new Indicator project
- cTrader generates a template with the basic structure already in place
- Write your indicator logic using the cTrader API (the set of functions and data that cTrader provides to your code)
- Click Build to compile. If there are errors, the editor will highlight them.
- Test the indicator by adding it to a chart
- Share it with the community or keep it for personal use
The cTrader API is well-documented, with examples and reference materials available on the cTrader website.
Tips for using custom indicators
- Start with the built-in indicators. With 70+ options already available, make sure you have explored the built-in library before looking for custom tools.
- Download from trusted sources. Stick to the official cTrader marketplace and cTDN for the safest experience.
- Test on a demo account. Always test new indicators on a demo account before using them for real trading decisions.
- Understand the logic. An indicator is only useful if you understand what it is calculating and what signals it produces. For example, learn how the RSI works before relying on it.
- Keep performance in mind. Complex indicators can slow down chart rendering. If cTrader starts feeling sluggish, check if a custom indicator is the cause.
- Check for updates. Developers sometimes release updated versions of their indicators. Keep yours up to date for the best performance and compatibility.
