PINE SCRIPT TO MT4/MT5 EA CONVERSION PLANNER

Pine Script to MT4/MT5 EA Conversion Planner

This is a lightweight conversion architect. It analyzes your TradingView script, detects Pine features that do not map cleanly to MQL, recommends MT4, MT5, webhook bridge or full native rewrite architecture, estimates engineering effort, and generates a developer-ready conversion brief.

Trading Logic & Pine Semantics

Uses strategy.entry/order/exit/close/close_all Needs pending orders: limit, stop, stop-limit, OCA-like behavior Needs pyramiding or multiple same-direction entries Opposite signal should close/reverse an existing position Partial closes or multi-stage TP1/TP2/TP3 Trailing stop: fixed, ATR, candle, MA, Supertrend or Chandelier Break-even trigger and SL offset Exit is indicator/time/session based, not only SL/TP Uses percent-of-equity, ATR risk, custom lot formula, grid/martingale

Why Pine Script Cannot Be Converted Line by Line to MQL

Pine Script is a time-series language running inside TradingView's chart engine. MQL4 and MQL5 are event-driven languages running inside MetaTrader, where code reacts to ticks, chart events, timer events, order events and broker execution rules. A professional conversion is a behavioral translation: signal engine, risk engine, order manager, state manager, logging and tester support.

Pine idea:
close[1]
ta.ema(close, 20)
strategy.entry()
request.security()

MQL architecture:
price-series access
indicator handles / buffers
OnTick / OnCalculate lifecycle
order and position API
broker constraints
explicit state management

Common Conversion Problems This Planner Checks

RepaintingFuture-dependent pivots, ZigZag, current HTF candles, lookahead and bar-0 logic may not behave live like they look historically.

MTF synchronizationA H1 value requested on a M5 chart must define whether the forming or completed H1 candle is used.

Synthetic candlesHeikin Ashi, Renko and Range backtests can diverge sharply from broker candles used for execution.

Strategy semanticsstrategy.entry, strategy.exit, pyramiding, OCA and reversal rules need explicit MT order/position behavior.

Webhook latencyAlert bridge projects need authentication, dedupe, freshness checks, logging and disconnect policy.

Broker metadataSuffixes, digits, tick value, lot step, stop levels, freeze levels and margin rules must be normalized.

FAQ

Can Pine Script be converted to MT4?

Yes, if the logic is known. Indicators can become MQL4 indicators and strategies can become MT4 Expert Advisors. Protected or invite-only scripts require functional recreation, not source extraction.

Can Pine Script be converted to MT5?

Yes. MT5 is usually recommended for new conversions because it has stronger tester support, indicator handles, CopyBuffer, multi-symbol capability and clearer trade/position architecture.

Can a TradingView strategy become an Expert Advisor?

Yes. The strategy rules must be rebuilt as an MQL signal engine plus order manager, risk manager, trade manager and validation logic. Exact profit matching is rarely guaranteed because broker data and execution differ.

Can TradingView alerts automatically open MT5 trades?

Yes, through a webhook bridge, local bridge or API relay. This is not the same as converting Pine to a native EA because TradingView remains the signal engine while MetaTrader becomes the execution layer.

Can repainting Pine indicators be converted to MT5?

They can be recreated, but historical visual similarity does not guarantee live similarity. The converted indicator or EA must define whether it uses forming candles, confirmed pivots or closed-bar non-repainting logic.

Why does my MT5 EA backtest differ from TradingView?

TradingView and MetaTrader use different data, spread, commission, intrabar assumptions, order models, sessions and broker rules. A professional conversion targets signal parity first, then realistic execution.

Can request.security be converted to MQL5?

Usually yes. MQL5 can use indicator handles, CopyBuffer and CopyRates for other symbols and timeframes, but candle synchronization and lookahead behavior must be specified carefully.

What is the difference between a webhook bridge and native MT5 EA?

A native MT5 EA runs all logic inside MetaTrader. A webhook bridge keeps Pine logic on TradingView and sends alerts to MetaTrader for execution, requiring server, authentication, deduplication and latency controls.
