Advanced Script Converter

Translate any indicator. Across six dialects.

Paste a script in Pine, MQL4, MQL5, EasyLanguage, MetaStock Formula, or AFL. Pick a target. ASC returns a structurally faithful translation in seconds with approximations called out up front. Free: 5 conversions per month.

What ASC does well

Structure first, semantics second

  • Preserves intent

    Control flow, indicator wiring, signal logic and variable names are mapped one-to-one. The shape of your script is recognisable on the other side.

  • 1,404 built-in mappings

    SMA, EMA, RSI, MACD, ATR and the full standard library translate to native equivalents. Pine covers 437, MQL4 270, EasyLanguage 295, AFL 230, MetaStock 172.

  • Any direction

    Six languages, thirty pair combinations. Pine to MQL5, AFL to EasyLanguage, MetaStock to Pine. Same engine, same review workflow.

How it works

From paste to compiled in four steps

  1. 01

    Paste the source

    Drop the original script into the converter panel inside the terminal. ASC auto-detects the language; you can override.

  2. 02

    Pick the target

    Choose where the script needs to live. ASC normalises the AST and re-emits in the target dialect.

  3. 03

    Read the diff and the warnings

    Every approximation, missing built-in, and manual-review hotspot is annotated inline. Nothing is hidden in the translation.

  4. 04

    Review, backtest, deploy

    Run the output on sample data in the target platform before any live use. Adjust the flagged spots; this is the part the converter cannot do for you.

Your job, not ours

What you sign up for when you press Convert

  • Review the diff

    Read every flagged line. ASC tells you which substitutions are approximate. Whether they are acceptable for your strategy is your call.

  • Verify on sample data

    Compile the output, run it on the same dataset as the original, compare signals tick-by-tick. Divergence after translation is normal; ignoring it is not.

  • Know the target platform

    MQL5 is not Pine with different keywords. Order types, account-info APIs, event handlers — understand the target semantics before relying on the translated code.

  • Confirm your license to convert

    ASC translates structure and logic. If the source script has a license, your right to convert and use the output is your responsibility.

Does ASC guarantee converted scripts run identically?
No. Conversion is automated code analysis and transformation. Language semantics, built-in function differences, and platform behaviours can produce divergent outputs. Treat every conversion as a starting point that needs verification.
How many free conversions do I get?
Free tier includes 5 conversions per month. Pro and Premium subscribers get unlimited conversions. The converter is inside the charting terminal — open it from the tools menu.
Can I sell or redistribute the converted script?
Only if the original script's license allows it. ASC translates code; it does not grant rights. Conversion rights and downstream distribution are entirely on the user.
Does TradersWeek claim ownership of the output?
No. We do not take ownership of converted code and we do not take responsibility for IP disputes that arise from someone converting code they did not have the right to convert.
What about alerts and chart drawing?
Platform-specific UI elements — alert delivery, plot styles, chart objects — often translate partially or not at all. ASC flags the gaps; you finish the job in the target environment.
Can I use the converted script for live trading right away?
Do not. Run it on the same sample data as the original, compare results, then paper-trade it for long enough to surface regressions. ASC is a translator, not a quality stamp.
Who do I contact if something looks wrong?
[email protected] with the input script, the chosen target language, and the diff. Bug reports with reproduction steps beat vague reports every time.
The Advanced Script Converter is offered for educational and research purposes. TradersWeek makes no warranty that converted code is functionally equivalent to the original and accepts no liability for losses, damages, or claims arising from converted-script usage — including trading losses from incorrect translations, missing features, or misinterpreted logic. The user remains responsible for confirming the right to convert the source, reviewing the output, verifying behaviour on sample data, and understanding the target platform constraints. Questions: [email protected].
