Convert a TradingView Strategy to an MT5 Expert Advisor

TradeSmithy Team4 min read

Short answer: there are two ways to run a TradingView strategy on MT5. A bridge sends TradingView alerts by webhook to an EA that places the trades — fast to set up, but dependent on TradingView, the bridge service and a paid TradingView plan. A native rebuild recreates the Pine Script rules as an Expert Advisor that runs on its own and can be backtested in MT5. There is no reliable automatic Pine-to-MQL5 converter; the languages work too differently.

Option 1: A TradingView-to-MT5 bridge

Your Pine strategy stays on TradingView. Each entry or exit fires an alert with a webhook; a bridge service receives it and passes it to an EA on your MT5 terminal, which places the order.

Good for: strategies that depend on TradingView-only indicators, or traders who want to keep editing in Pine.

Costs and limits:

  • TradingView webhooks need a paid TradingView plan.
  • A bridge subscription, usually monthly.
  • Three services in the chain — TradingView, the bridge, your terminal — and a failure in any one means a missed or orphaned trade.
  • Latency between the alert and the fill.
  • No MT5 backtest: you are testing on TradingView's data, trading on your broker's.

Option 2: Rebuild the strategy as a native EA

The rules are recreated as an Expert Advisor that runs entirely in MetaTrader.

Good for: anything built from standard indicators and price rules — which is most strategies.

What you gain: no external dependencies, one bill fewer, and a strategy you can backtest on your broker's own data in the MT5 Strategy Tester.

Why there is no reliable automatic converter

Pine Script and MQL5 disagree about how a strategy runs, not just syntax:

  • Series versus events. Pine evaluates the script once per bar over the whole history; MQL5 reacts to ticks and you choose when to evaluate.
  • When orders fill. By default a Pine strategy decides at the bar close and fills at the next bar's open. An EA can do the same — or fill mid-bar — and the choice changes results.
  • Indicators without an MT5 equivalent. Supertrend, many community scripts, and anything built with request.security tricks need custom work.
  • Different data. TradingView's feed is not your broker's feed; prices, spreads and session times differ.

AI tools can draft a translation, but they inherit every one of these gaps and add their own.

Translating Pine concepts to EA building blocks

ta.rsi, ta.macd, ta.bb, ta.atrTechnical Indicator → RSI, MACD, Bollinger Bands, ATR
ta.crossover(a, b)Two Comparisons: a > b now and a ≤ b on the previous bar, into an AND

strategy.exit(stop=, limit=)Stop loss and take profit on the order, in points
strategy.closeClose Order

Most Pine strategies map onto ten or fifteen nodes. Custom Pine indicators with no MT5 twin need an MT5 version compiled as .ex5, which you can then wire in as a custom indicator.

Checking the conversion

Do not expect identical results — expect explainable ones. Pick a period, export the trade list from TradingView's Strategy Tester and from the MT5 tester, and compare the first twenty trades. Entries a bar apart usually mean a bar-close versus intrabar difference; small price differences are the data feed. Anything else is a logic difference worth fixing before going further.

Rebuild your TradingView strategy natively

Start free on TradeSmithy: recreate the rules on the canvas and export MQL5 (or MQL4) with no bridge in the chain — one export a month is free. On Pro, paste your rules into the AI assistant as a description and let it build the graph, then queue a backtest on our servers. Then test it properly in MT5.

Frequently asked questions

Can I automatically convert Pine Script to MQL5?

Not reliably. Execution model, indicator implementations and data all differ, so a converted strategy needs rebuilding and retesting either way.

Is there a free way to trade TradingView signals on MT5?

Bridges generally need a paid TradingView plan for webhooks plus a bridge subscription. Rebuilding the strategy as a native EA avoids both.

Why do my TradingView and MT5 results differ?

Different data feeds, spread, and when orders fill relative to the bar close. Compare trade lists to see which.

Can I convert a TradingView indicator to MT5?

Standard indicators already exist in MT5. A custom Pine indicator must be rewritten in MQL5 and compiled; the EA can then call it through iCustom.
