MQL5 development · Pineify guide

Generate an MT5 Expert Advisor, then verify it in MetaTrader

A plain-language prompt can start an EA project, but it does not remove the setup and testing work. Pineify provides editable MQL5 source and requested compiler checks. Your MT5 environment is where you verify dependencies, inputs, and runtime behavior.

Open Pineify

Open the Coding Agent and select MQL5. Account and plan usage limits apply.

Know what you need before installation

An explicit EA specification

Document the symbol, timeframe, closed-bar or tick behavior, entry and exit rules, position scope, and sizing units. Ask the assistant to identify missing decisions before it generates order handling.

The source and its dependencies

Keep the final .mq5 source and list of required includes or custom indicators. Pineify’s current remote check submits one source file; it may not have files installed on your computer.

MetaEditor and an MT5 test environment

Compile locally with the correct dependencies and examine diagnostics. Select a suitable demo account and verify its symbol settings and account mode. A browser coding session is not an installed EA.

A reproducible test record

Retain the exact source version, inputs, symbol, dates, and tester settings with each result. If a rule changes, the previous test no longer describes the current program.

Ask for a reviewable first version

Illustrative request for your own development workflow, not a tested trading strategy.

Draft an MQL5 EA that only logs the proposed entries and exits from my rules. Do not submit orders. Expose the relevant parameters and explain the dependencies, account-mode assumptions, and duplicate-signal handling. List the tests I should run before requesting an execution-enabled revision.

1. Generate and request checking
Open the Coding Agent, choose MQL5, and review the generated source. Explicitly request a syntax check or a fix. Resolve errors or a failed check before treating the file as verified.
2. Save and compile in MetaEditor
Save the EA in the appropriate MQL5 Experts location and provide its required files. Compile in MetaEditor and review the diagnostics. Do not assume a web checker has produced a deployable EX5 for you.
3. Inspect in Strategy Tester
Choose the program, symbol, dates, inputs, and modeling settings. Use the visual result and logs to compare decisions with your specification. Test a separate forward period rather than relying on the development sample alone.
4. Assess demo operation
Check inputs, permissions, symbol constraints, and logs in a demo environment. Confirm how the EA behaves after a restart and how to stop it. A VPS is an operational hosting choice, not proof of strategy quality.

What still needs verification

No-coding describes how you begin the draft; it does not mean no MetaEditor, no review, or no maintenance. If you cannot judge a change to order handling, obtain a qualified review before using that revision.

Generated code is not guaranteed to work on every broker or account. Netting and hedging behavior, symbol rules, permissions, and dependencies can affect execution. Compilation and historical results do not guarantee live performance.

Questions about this workflow

Can I create an EA without typing the initial MQL5 code?

Yes, you can describe the requirements and ask Pineify for a draft. You still need to inspect the result and complete the MT5 compilation and testing workflow.

Do I need MetaEditor?

Use MetaEditor to compile the final source in your local environment and inspect its diagnostics. Pineify’s remote syntax check does not replace dependency and runtime verification on your installation.

Do I need a VPS?

A VPS can keep a configured terminal running when your own computer is off, but it is not required to draft or locally test an EA. Hosting, broker access, and ongoing operation are separate from source generation.

Is the generated EA ready for a live account?

That cannot be established by generation or a compiler pass. Review its rules, test failure cases and historical behavior, and assess demo operation. None of these checks guarantees future returns.
