We assess your EX4, identify the requested output and agree a file-specific quote before work begins. Request an assessment → SCOPE Agree the outcome before work starts. Source recovery and MT5 migration are different requests. Tell us if your end goal is to run the program on MT5, because that needs a separate implementation and test plan.

We help turn those rules into a practical scope for MQL4, MQL5 and related utilities. Request an assessment → SCOPE Agree the outcome before work starts. Separate the core version from optional features. A small, testable first version makes it easier to identify a rule misunderstanding before adding more complexity.

We review the file, environment, inputs and available evidence to define the investigation. Request an assessment → SCOPE Agree the outcome before work starts. Compilation, historical testing and continuous demo operation answer different questions.

ON THIS PAGE Start with the file you actually have Explain the result you need Use a private handoff Start with the file you actually have For an MT4 project, list EX4 executable files separately from MQ4 source and MQH includes. For MT5, make the same distinction between EX5 and MQ5. Keep the original filenames and make a short inventory; a folder screenshot can help explain a package. Explain the result you need Editable source, an expiry repair, a platform migration and a new implementation have different scopes. Say which result matters. Include whether the program is an indicator, EA or script and describe a representative task it currently performs. Use a private handoff Use the enquiry form for the brief, then exchange program files through the agreed private channel. Include companion indicators, presets and setup notes where available.

ON THIS PAGE Inventory the source project Write a behavior checklist Verify in stages Inventory the source project Start with MQ4 and MQH source, any custom indicators, presets and external interfaces. Identify what is missing before asking for a delivery date. An EX4 executable by itself is not an editable source project. Write a behavior checklist For an indicator, record its plotted values, chart objects, alerts and parameter effects. For an EA, document entry and exit rules, order handling and position sizing. Review the target account setup and required dependencies before implementation. Verify in stages Review compilation in the target MetaEditor, then compare selected charts or test periods using the agreed inputs. Continue with demo observations for behaviors that depend on arriving ticks or changing positions. Record differences explicitly instead of using a clean compile as proof of equivalence.

URL: https://mqlfix.top/guides/verification-before-balance/ Language: en Updated: 2026-11-11 PRACTICAL GUIDE What to check before approving a verification build A repeatable acceptance process for source recovery and repair work. ON THIS PAGE Confirm the delivery list first Compare the same conditions Make approval explicit Confirm the delivery list first Your quote should identify the program and version, expected files, included dependencies and any agreed modifications. A program repair and full source delivery are separate outputs. Keep the written scope alongside the reference file. Compare the same conditions Use the same terminal environment, symbol, timeframe, inputs and relevant dates. Compare displays, alerts or EA orders according to the agreed scope. Keep screenshots and logs with timestamps when a discrepancy occurs. One matching image does not cover every possible input combination. Make approval explicit Report either approval or reproducible differences, then confirm the remaining balance and final file handoff.

URL: https://mqlfix.top/guides/indicator-repainting/ Language: en Updated: 2026-11-11 PRACTICAL GUIDE How to brief an indicator repainting check Separate historical appearance from observations made as bars arrive. ON THIS PAGE Define the behavior of concern Keep a timed record Agree what a fix should do Define the behavior of concern A changing current-bar value and a signal disappearing from a closed historical bar are different observations. Identify the exact buffer, arrow, label or alert that matters and the point in time when you expect it to become fixed. Keep a timed record Use a demo or observation environment and save the input settings, symbol, timeframe and observations as new data arrives. Keep the original indicator unchanged for comparison. Record refreshes or restarts, because they may affect what is shown. Agree what a fix should do A proposed non-repainting variant may change when a signal becomes available.

URL: https://mqlfix.top/guides/write-an-ea-brief/ Language: en Updated: 2026-11-11 PRACTICAL GUIDE Write an EA brief a developer can actually implement Replace vague strategy descriptions with rules and worked examples. ON THIS PAGE Specify the first trade Define exits and sizing Create an acceptance example Specify the first trade Describe the signal, the data it uses and whether it is evaluated on a new tick or a closed bar. Show one example where a trade should happen and one where it should not. Name the symbol and timeframe assumptions. Define exits and sizing State stop and target units, partial exits, sizing rules and whether multiple positions may coexist. Describe behavior after a rejected order, terminal restart or manual intervention. List every input that should be configurable. Create an acceptance example Use a short scenario with clear expected actions rather than a profit target. Separate essential behavior from optional panels, alerts and reporting. Confirm whether source, dependencies and installation notes are included in the quote. Need help with this? See the related service → YOUR NEXT STEP Have a file or an idea? Start here.

It is not an automatic purchase or a universal file-conversion promise. 01 / 04 From brief to delivery. 01 Describe & send Identify the platform and goal; share files privately. 02 Agree the scope Confirm feasibility, output, price and delivery window. 03 Review the build Compare against the original under agreed conditions. 04 Approve & receive Settle the agreed balance and receive the final files. SOURCE-RECOVERY REFERENCE A quote for your file. These ranges apply to a single indicator or EA recovery request, not every repair, migration or custom build. Confirm the total and delivery list before payment. One indicator $80–200 USD One Expert Advisor $200–500 USD BEFORE YOU COMMIT Questions worth settling first. Is the first assessment free? Yes. Send a brief to discuss feasibility and the output you need. Project work begins after the scope, quote and any deposit are agreed. Is every EX4 or EX5 recoverable? Do not assume that from a file extension or a general marketing claim. We assess the actual file, version and required output before confirming a project. Is a deposit an extra fee? An agreed deposit is credited toward the project total. Confirm the deposit, remaining balance and cancellation terms in your quote. Can I get MT5 from an EX4? Source recovery and platform migration are separate tasks. Tell us what files you have and whether MT5 is the end goal. The local file tool does not perform an automatic conversion.
