Convert Pine Script to MetaTrader 5

Use HorizonAI to transform Pine Script into MT5 (MQL5) code

Follow these steps to convert an existing Pine Script strategy or indicator into MetaTrader 5 (MQL5) using HorizonAI.

Before you start

  • Create a free HorizonAI account and sign in.
  • Have your Pine Script ready to paste.

1) Create a new script in HorizonAI

  • Click New Script.
  • When asked for a language, choose MetaTrader 5 (MQL5) — this is the target language you want to receive.

You always select the language you want to end up with. For Pine → MT5, pick MetaTrader 5.

2) Choose “I have existing code”

  • Select Existing code (instead of starting fresh).
  • Paste your existing Pine Script into the input.

3) Ask HorizonAI to convert

  • In the prompt, say: “Please convert this Pine Script into MetaTrader 5 (MQL5).”
  • Click Go.

4) Review and download

  • HorizonAI will produce MT5 (MQL5) code based on your input.
  • Review the output, then copy or download the generated file for MetaEditor.

Open the result in MetaEditor and compile. If you need changes, adjust your prompt in HorizonAI and regenerate.

Tips for better conversions

  • If your source is a Pine strategy, mention it so trade logic maps to MQL5 orders.
  • Include timeframe, symbol assumptions, or broker specifics if relevant.
  • If you have custom inputs, mention defaults so they become input parameters in MQL5.

FAQs

  • Does it work for indicators and strategies? Yes. Clarify whether your Pine code is an indicator or strategy.
  • Can I keep iterating? Yes. Paste revised Pine code or update your prompt and regenerate.
  • What if it doesn't compile? Check MetaEditor errors, then paste them into HorizonAI and ask it to fix.
