Every week, traders search for "Pine Script to EA" with the same goal: a strategy tested for months on TradingView that now has to run on MT5 - because their prop firm requires it, or their broker is not on TradingView. In short: the same trades, on MT5, without rebuilding everything from zero. There are only three real routes, and one of them does not convert code at all.

Option 1: Rewrite the strategy in MQL5 by hand

The "proper" answer: a developer ports your Pine logic to a native MQL5 Expert Advisor. The most flexible result, with real costs:

  • Cost: hundreds to several thousand dollars per strategy, depending on complexity.
  • Time: days to weeks, plus debugging while the EA inevitably behaves slightly differently from the chart.
  • Double maintenance: every tweak to your Pine Script means updating the MQL5 version too. Two codebases, two places to introduce bugs.

A hand-written EA is legitimate if the strategy is simple and final; for most traders iterating on it, it is expensive overkill.

Option 2: Automatic Pine-to-MQL5 converters

Converters promise the dream: paste your Pine, get an .mq5 file. They struggle with exactly the parts that make your strategy work:

  • Missing equivalents: many TradingView built-ins and community indicators have no direct MQL5 counterpart, so the output fails to compile or substitutes different behavior.
  • Repainting: Pine executes bar by bar on TradingView's data; converted code can calculate at different moments, so signals diverge - sometimes only in fast markets, which is when it hurts most.
  • Risk: a converter bug does not crash. It quietly trades a strategy that is not quite yours.

At best, a converter is a starting point for a developer, not an end product.

Option 3: Don't convert the code - bridge the signals

The third option skips conversion completely: keep your Pine Script running on TradingView and execute its signals on MT5 through a bridge. Your alerts go via webhook to SignalForge, and a native MT5 EA executes them on your account with real trade management on top:

  • Multi-TP: split each entry into several take-profit levels.
  • Breakeven and trailing stops: protection moves automatically as the trade goes your way.
  • Drawdown controls: daily and overall loss limits, max lot size - the toolkit that matters on prop accounts; see our MT5 risk management EA guide.
  • Filters: trend and news filters so a signal is not executed in conditions you do not want.

Because your indicator logic never leaves TradingView, what you backtested is what executes - the EA is execution and risk management, not a re-implementation of your strategy. Weighing it against other bridges? The SignalForge vs PineConnector comparison covers the differences honestly.

When each route makes sense

Rewrite by hand if the strategy is final and you want zero dependence on TradingView. Converters only if you will audit and fix the output anyway. The bridge if you iterate on your strategy and want it live on MT5 today, with prop-grade risk management included.

How to run your Pine strategy on MT5 with SignalForge

Setup takes minutes; the full walkthrough with screenshots is in the documentation:

  1. Create the Pine alert: in your TradingView strategy or indicator, add an alert with the SignalForge webhook URL as the Webhook endpoint.
  2. Connect your account: link your MT5 account in the dashboard and download the EA.
  3. Attach the EA: drop it on any MT5 chart and enter your token - it connects back to the bridge.
  4. Set lot and risk: fixed lots or risk-based sizing, plus multi-TP, breakeven, trailing and drawdown limits. Test on demo first.

From then on, every alert your Pine Script fires executes on MT5 automatically - typically in milliseconds end to end.

FAQ

Can I convert Pine Script directly to MQL5?

Not automatically. Pine Script and MQL5 are different languages with different execution models, so there is no reliable one-click compiler. The code has to be rewritten by hand or run through a converter, and both routes need careful testing.

Do I need to know MQL5?

Not if you bridge your signals. Your Pine Script keeps running on TradingView and fires alerts; SignalForge's native MT5 EA receives them via webhook and executes them with your risk settings. You only need MQL5 if you rewrite the strategy yourself.

What happens with repainting or indicators without an MQL5 equivalent?

This is where converters fail: the generated code silently diverges from your script. With the bridge, your indicator logic never leaves TradingView, so it behaves exactly as on the chart - just fire your alert on bar close if your script can repaint.

How much does it cost?

SignalForge starts at $4.99/month with a 14-day free trial, no card required. A hand-written EA typically costs hundreds in freelancer fees, plus maintenance every time you change the strategy.

Does it work for prop firms?

Yes. The EA includes drawdown controls, multi-TP, breakeven and trailing stops - exactly what FTMO-style accounts demand. As always, check your firm's current written rules on automation before trading a funded account.
