Convert Trading Robots to cTrader cBots

What this Workflow Does

The Convert a Trading Robot workflow translates an existing automated trading strategy from one platform into a cTrader cBot, with the goal of preserving behaviour as closely as possible.

This process focuses on maintaining the original strategy rather than improving it. Entry and exit rules, stop loss and take profit behaviour, and position management are all carried across and adapted to the cTrader Algo API. Platform-specific execution logic is mapped carefully so the converted robot behaves consistently.

This is a conversion workflow, not a redesign or optimisation process.

Xen AI – Convert Trading Strategies

Watch this video to see how a MetaTrader Expert Advisor or TradingView Pine Script strategy can be converted into a cTrader cBot using Xen AI. The demonstration shows how trading logic is translated into clean, compile-ready C# code for cTrader.

Tip: Set the video quality to HD (1080p) for the best viewing experience.

Supported Source Platforms

Xen can convert robots from several common platforms, including:

  • MetaTrader 4 (MQL4)
  • MetaTrader 5 (MQL5)
  • TradingView Pine Script strategies
  • NinjaTrader strategies
  • Other structured algorithmic trading code

The converted result is always a cTrader cBot written in C#.

When to Use This Workflow

Use this workflow when you already have a working trading robot and want to run the same strategy on cTrader. It is best suited for situations where the goal is to preserve the original behaviour rather than change it.

This workflow should not be used to redesign or improve a strategy. If you want to build a new system or significantly modify the logic, use Build an Automated Trading Robot instead.

What You Should Prepare

Before starting, make sure you have the complete source code of the trading robot. Partial snippets are not sufficient, as missing logic will lead to incorrect results.

You should also understand how the strategy works, including:

  • entry conditions
  • exit conditions
  • stop loss and take profit rules
  • position sizing logic
  • any indicators used

If the strategy depends on multiple files or external libraries, simplify it into a standalone version where possible before converting.

Large Strategy Files

Xen supports source-file uploads up to 32 KB for a single direct conversion. This limit applies to the uploaded file size, not the number of lines in the strategy.

Large trading systems often contain connected logic, shared state, dependencies and platform-specific behaviour. Current AI technology cannot reliably convert a large codebase in one request without risking omitted logic, incomplete cTrader code or changes in strategy behaviour.

If your source file is larger than 32 KB, divide the strategy into smaller logical components rather than arbitrary blocks of lines. Convert related areas separately—for example, signal logic, indicator calculations, risk management and order handling—then integrate the converted components and compile the complete cBot in cTrader.

If you need help converting a large or complex strategy, contact our development team at development@clickalgo.com.

Complete-source response limits

Source uploads and AI responses have separate limits. Direct conversion uploads accept up to 32 KB; existing cBot and indicator projects accept uploads up to 512 KB. An accepted upload may still be too large for Xen to return as a complete updated source file. Xen continues to provide complete downloadable source files, so you do not need to assemble code fragments.

A project-size warning appears near the request box when the actual source reaches 24,000 characters. Above approximately 30,000 characters it shows an exceeded-limit message. The warning updates after source uploads, generated changes, project loading, task changes and snapshot recovery, and clears when the source becomes smaller. It applies to tasks that generate source code.

For a complete rewrite, Xen estimates source tokens by dividing the character count by 2.5 and rounding up, then adds 25% for changes and 1,000 tokens for framing and reasoning. The main response ceiling is 16,000 output tokens. This is a conservative estimate, not a guarantee: new requirements can grow the source, and reasoning also consumes output capacity. Requests with an image retain a smaller response allowance.

If the estimated rewrite exceeds the absolute response ceiling, Xen blocks generation before checking credit. Adding credit cannot remove this restriction. Simplify the requirements, ask a question or request analysis without rewriting the file, or contact development@clickalgo.com for developer assistance. Questions and analysis remain subject to the normal input and credit limits.

If the source fits the absolute ceiling but the available credit cannot cover the estimated rewrite, Xen shows a credit-specific blocking message. Adding credit may help in this case. Neither type of preflight block calls the generation provider or uses generation credit, and your last complete source remains available.

A response that stops after generation begins may still consume chargeable tokens. Xen does not save incomplete output as your current source or offer build and download actions for it. Your last complete file and existing recovery tools remain available: use Undo, source history or a saved project version to restore an earlier file. Simplify the next request or seek developer assistance instead of repeatedly asking the AI to continue or retry.

How to Interact with Xen

When using this workflow, keep requests clear and focused on conversion. The objective is to translate the existing strategy, not to change it.

Good examples:

  • “Convert this MT5 trading robot into a cTrader cBot.”
  • “Preserve all entry and exit logic exactly.”
  • “Keep stop loss and take profit behaviour unchanged.”
  • “Do not add new strategy features.”

Avoid requests such as:

  • “Improve the strategy while converting.”
  • “Optimise the trading logic.”
  • “Add new indicators during conversion.”

Conversions work best when the scope is limited to faithful translation.

How Xen Performs Robot Conversions

Xen begins by analysing the original robot logic and identifying how it maps to cTrader. It then adapts order handling, indicator usage, and lifecycle events to match the cTrader API. The strategy is reconstructed as a complete cBot, with the original behaviour preserved as closely as possible. The output includes:

  • a complete, compile-ready C# cBot file
  • an explanation of any behaviour that could not be replicated exactly

If a feature cannot be mapped directly, Xen will highlight the limitation and provide the closest possible alternative.

Common Mistakes to Avoid

Most conversion issues come from unclear or incomplete inputs. Avoid converting partial code or combining conversion with new feature requests. It is also important to understand that different platforms handle orders and data differently. Always verify that behaviour matches expectations after conversion.

After conversion, compile the cBot in cTrader Automate and run a backtest. Compare the results with the original platform to confirm that the behaviour is consistent. Only after validating the logic should you begin making improvements or adding new features.
