MT5 EA Builder: Specify and Validate MQL5 Rules
An MT5 EA builder assists creation of MQL5 Expert Advisor source from a specification. Pineify can help draft and revise that source, but compilation, strategy behavior, and account execution are separate validation steps.
How Pineify Helps
Describe the intended MQL5 program in Pineify’s Coding Agent and inspect the generated source and compilation feedback. Compile the source in your target MetaEditor and run MT5 Strategy Tester locally. Pineify’s TradingView parameter optimizer and CSV backtest reports are not MT5 EA execution or report-import services.
Define events and state explicitly
Specify whether decisions use ticks, completed bars, timers, or trade events. Name the indicator inputs, bar shifts, position constraints, and the action after a restart. An EA can contain order logic, while a custom indicator primarily calculates or displays values. A generic generation request does not ensure every needed error or recovery path exists.
Separate requested features from defaults
Ask explicitly for any spread filter, partial close, trailing stop, session filter, or loss threshold. Check the source for each requested behavior; do not assume every generated EA includes ATR trailing, Kelly sizing, or drawdown protection. Define numeric units against the broker symbol specification, especially for index CFDs with varying point and contract conventions.
Compile and inspect trade results
MQL5 source uses MQ5 and compiled output uses EX5. Review MetaEditor diagnostics and dependencies. Confirm account mode, valid volumes, stop distances, permissions, and server results. OrderSend returning true is not confirmation of a completed fill. Syntax checking can identify language errors but does not certify the strategy or risk controls.
Run controlled MT5 tests
Record source version, symbol, timeframe, data, model, costs, and inputs. Inspect individual trades and the Journal before ranking summary metrics. Reserve independent evaluation data and test interruptions and manual position changes in a monitored demo setup. This guide contains no first-compile benchmark or measured win-rate/profit improvement.
Treat cross-platform output as an adaptation
A Pine Script strategy and an MQL5 EA have different event, fill, and hosting models. Generating both does not establish identical behavior or automatic live execution on TradingView. Compare timestamps, signals, sizing, and fill assumptions explicitly before describing the two programs as equivalent.
