PineScript to MT4/MT5 Conversion

Take your TradingView strategies live. We convert PineScript indicators and strategies into production-grade MQL4 and MQL5 code — Expert Advisors, custom indicators, and utility tools.

Convert Your Script

What We Convert

PineScript Indicators → MQL Indicators

  • All built-in PineScript functions replicated in MQL (ema, sma, rsi, macd, bb, supertrend, etc.)
  • Multi-timeframe indicator panels (e.g., higher timeframe filter on lower timeframe chart)
  • Custom plots, hline, fill, and level lines converted to MQL buffers
  • Input parameters exposed as MQL extern/input variables
  • Bar-color, bg-color, and label/drawing logic preserved

PineScript Strategies → MT4/MT5 EAs

  • Entry/exit logic from strategy.entry, strategy.exit, strategy.close
  • Stop-loss and take-profit mapped to MQL OrderSend/PositionOpen
  • Trailing stop logic converted from PineScript to MQL tick-based trailing
  • Pyramiding and position sizing rules preserved
  • Strategy tester compatibility for MT4/MT5 backtesting

How We Convert PineScript to MQL

PineScript and MQL are fundamentally different languages. Pine runs bar-by-bar on TradingView's servers; MQL runs tick-by-tick on your local machine. A direct line-by-line translation produces fragile code. Our process respects each platform's strengths:

1. Audit

We review your PineScript for TradingView-specific functions (request.security, ta.*, strategy.*) and identify equivalent MQL patterns.

2. Architecture

We design the MQL structure — OnInit, OnTick/OnCalculate, OnDeinit — mapping PineScript's execution model to MQL's event-driven model.

3. Build

We write the MQL code with proper rate-of-change detection, buffer management, and order execution logic — not a naive line-for-line copy.

4. Test

We backtest the converted code against your TradingView results to verify matching signals and performance metrics.

Real Conversion Examples

Example: PineScript RSI Strategy → MQL5 EA

// PineScript (original)
if (ta.crossover(ta.rsi(close, 14), 30))
    strategy.entry("Long", strategy.long)
if (ta.crossunder(ta.rsi(close, 14), 70))
    strategy.entry("Short", strategy.short)
// MQL5 (converted)
double rsi = iRSI(_Symbol, _Period, 14, PRICE_CLOSE);
static double prevRsi = 0;

if (prevRsi != 0) {
    if (prevRsi < 30 && rsi >= 30)
        trade.Buy(lotSize);
    if (prevRsi > 70 && rsi <= 70)
        trade.Sell(lotSize);
}
prevRsi = rsi;

Note the architectural shift: PineScript uses crossover/crossunder functions on bar close; MQL5 requires manual rate-of-change detection on every tick. Every converted strategy accounts for this difference, plus spread, slippage, and broker execution rules.

What Cannot Be Converted

Transparency matters. These PineScript features have no direct MQL equivalent:

  • TradingView alerts — MQL has no built-in webhook system (custom solution required, e.g., WinInet/WebRequest)
  • PineScript drawings (box.new, label.new) — MQL chart objects exist but work differently; we reimplement the logic
  • request.security() — MQL handles multi-timeframe via iClose(Symbol, PERIOD_H1, ...); the pattern changes
  • TradingView-specific broker emulator — MQL backtester uses actual broker rules; results will differ from PineScript's simplified model
  • PineScript tables — MQL dashboard equivalent exists but must be built manually with objects

We flag these before starting so there are no surprises.

PineScript Conversion FAQ

How much does PineScript to MT4 conversion cost?

A simple indicator conversion starts at $100-$200. Strategy conversions with full EA logic (entry/exit, risk management, trailing) range from $300 to $1,500 depending on complexity.

How long does a PineScript conversion take?

Simple indicators: 1-3 business days. Standard strategies: 3-7 business days. Complex multi-symbol or multi-timeframe systems: 1-3 weeks.

Will my converted EA match my TradingView backtest results?

Not exactly. MT4/MT5 backtester uses tick data and broker execution rules, while TradingView uses a simplified bar-close model. Signals will match, but P&L, drawdown, and fill prices will differ. We validate signal alignment during testing.

Can you convert PineScript to both MT4 and MT5?

Yes. We convert to MQL4 (MT4), MQL5 (MT5), or both. MQL5 is recommended for new projects due to better execution model, multi-asset support, and superior backtesting.

Do I need to provide the full PineScript source code?

Yes, we need the complete PineScript source to audit TradingView-specific functions and ensure an accurate conversion. We treat your code as confidential.
