Converting an MT4 trading strategy to TradingView normally means rewriting the strategy from MQL4 into Pine Script and then checking that the original trading rules still behave as expected. With Xen AI for TradingView, it can handle much of this process automatically.
In the demonstration below, we start with an existing MT4 strategy, select the strategy conversion task in Xen, choose an AI model and paste in the original MQL4 source code. Xen then converts the strategy into Pine Script and uses its build process to check the generated code before copying it into TradingView.

Converting an MT4 strategy to TradingView
MetaTrader 4 strategies are generally written in MQL4, while TradingView strategies use Pine Script. The two platforms also handle orders, bars, and strategy execution differently, so a useful conversion isn't simply a matter of replacing one programming syntax with another.
The aim is to identify the original entry conditions, exits, stop losses, take profits, filters and other trading rules and reproduce them using TradingView's strategy functions. For this example, we selected the strategy conversion task in TradingView Xen and chose the AI model that would handle the conversion. We then pasted the original MT4 strategy code directly into Xen.
We didn't need to manually describe every part of the strategy because Xen could analyse the MQL4 source code and identify the trading logic in the existing program. The conversion request instructed Xen to recreate the strategy as Pine Script for TradingView while preserving the original trading behaviour wherever possible.
Auto Build Check
Once the conversion started, Xen generated the TradingView strategy and used its automated build process to check the code as it was produced. This is an important part of the workflow because generated Pine Script can contain syntax problems, unsupported functions or other issues that prevent it from compiling. Rather than simply returning a block of code, Xen can work through these issues during the build process.
Publishing the strategy to TradingView
We opened the Pine Editor, created a new strategy and replaced the default code with the Pine Script generated by Xen. We then saved and compiled the strategy in TradingView. In the demonstration, the converted code compiled successfully without requiring any manual corrections. After compilation, we attached the strategy to the chart so we could visually check the entries, exits, and overall behaviour. Once the converted strategy was running on the chart, you could use TradingView's Strategy Tester to view the historical backtest results.
This is where you should check the conversion, rather than assuming a successful compile means the job is complete. Inspect individual trades to confirm the entry and exit rules match the original strategy, and that stop losses, profit targets, and other conditions behave as intended.
Backtest results between MT4 and TradingView will not always be identical. The platforms can differ in areas such as order execution, bar processing, intrabar behaviour and multi-timeframe calculations. The key is to verify that the original trading logic is reproduced correctly.
This demonstration shows the complete workflow from an existing MT4 strategy to a working TradingView strategy. We selected the conversion task, chose an AI model, pasted in the MQL4 code, and let Xen generate and check the Pine Script.
The resulting code was then copied into TradingView, saved, compiled and attached to the chart before the backtest results were reviewed.
For traders with existing MT4 strategies, this provides a practical way to move trading logic onto TradingView without manually rewriting the entire strategy in Pine Script.
