Convert Pine Script to MQL4 / MQL5
Your strategy works on TradingView but you want it trading automatically in MetaTrader. We port Pine Script indicators and strategies to MQL4 and MQL5 — as a custom indicator or as a full expert advisor — keeping the entry and exit logic identical and documenting every place where the two platforms cannot behave the same way.
How the conversion works
1. Source review
We read the Pine Script source (or your published TradingView chart setup) and list every input, plot, alert condition and entry/exit rule that has to survive the port.
2. Logic audit
Pine constructs that behave differently in MQL — repainting on the forming bar, security() lookahead, per-bar recalculation — are flagged and agreed with you before coding starts.
3. MQL implementation
Indicators are rebuilt with data buffers and graphical objects in MQL4/MQL5; strategies become an expert advisor with order handling, stops, position sizing and logging.
4. Comparison & handover
Signals are compared bar by bar against the TradingView original on the same symbol and timeframe, then the EA is tested in the MetaTrader strategy tester and handed over with sources and a short manual.
What maps to what
| Pine Script | MQL4 / MQL5 |
|---|---|
| ta.* / built-in series (sma, ema, rsi, atr) | iMA / iRSI / iATR handles or custom buffer math |
| plot(), plotshape(), bgcolor() | Indicator buffers, arrows and chart objects |
| alertcondition() / alert() | Alert(), SendNotification(), push and email alerts |
| strategy.entry / strategy.exit | OrderSend / CTrade with SL, TP and trailing logic |
| request.security() multi-timeframe | Explicit higher-timeframe handles without lookahead |
| input.* settings | MQL input parameters with the same defaults |
Before you send a strategy
- • Share the Pine Script source, or the indicator settings and screenshots if the code is closed.
- • Tell us the symbol and timeframe the strategy is meant for — MetaTrader tick data differs from TradingView data, so signals can differ on the forming bar.
- • Say whether you need an indicator with alerts, or a fully automated EA that sends orders.
- • Strategies that rely on repainting signals cannot be automated as-is; we propose a non-repainting variant instead.
