The verified build
Code that looks right is easy. Code you can check is the job.
A coder, or an AI, can write an EA that compiles and trades. The hard part is knowing it trades your rules and nothing else. Every build here is made to show that.
Your rules, as decisions
We rewrite your rules as numbered decisions. Every gap, like a touch or a close, gets resolved in writing before any code.
The code
MQL5 for MetaTrader 5, with your limits as settings you can read and change.
A trade-by-trade match
Every trade compared with a reference: a checker written from your rules or your TradingView list. On your broker's tick data.
Your risk rules, one by one
Daily and total loss limits, news windows, sessions and position caps, each one tested in the MT5 Strategy Tester.
A log of every no
When the EA skips a signal, the log records which rule stopped it and when.
Your MT5 first
You run it on your own terminal before the final payment, with the report in hand.
What each project includes is listed in its written quote. The risk-rule checks and the decision log come with the builds that need them.
Measured builds
Three builds. Every trade measured.
Each dot is one trade or signal from the MT5 Strategy Tester, grouped by result, not in time order. The reports show whether an EA follows its rules, not whether a strategy makes money.
520 of 637
TradingView strategy to MT5
A direct conversion matched 280 of TradingView's 637 trades. Ours matched 520 on entry, side and exit. Of the other 117, 85 differ by design, 18 come from the price feed, 9 from spread and ticks and 5 from the warm-up.

A decision log inside the EA
The log inside the EA showed why it stopped 626 of 1,202 signals. The top reason, 465 times, was not a filter: its own trade was still open.

Full report (PDF)The difference
Where a quick code job stops, and a verified build keeps going.
| Topic | A quick code job | A verified build |
|---|---|---|
| Starting point | Your description, read the way the coder reads it | Your rules as numbered decisions, every gap resolved in writing with you |
| Proof it matches | A backtest screenshot | Every trade compared with a reference, each mismatch with its cause |
| Fills | Assumed | Measured on your broker's tick data |
| A skipped trade | You guess why | The log names the rule and the time |
| If it can't be built as written | Built anyway | We say so before you pay, with what can be built instead |
| Payment | Often upfront | Milestones after a written contract, the last one after you test it |
What you receive
A build you can check, not just run.
- The written spec. Your rules as numbered decisions, agreed before coding.
- The EA. The .ex5 licensed for your own use, your limits as settings. Source code with a transfer of rights when your project includes it.
- The verification report. Trade by trade against the reference, on your broker's tick data, with every difference explained.
- Installation guide and settings. So it runs the same on your terminal as in the report.
- A correction period, set in your contract. If the EA departs from the spec in that time, we fix it at no extra cost.
What we don't do
- Promise results. We build software that does what your rules say.
- Sell signals or manage anyone's money.
- Decompile an EA. We only change code you own or have the right to change.
- Tune a strategy to look good in a backtest.
- Ask for your logins, passwords or payment before a written contract.
How an engagement runs
The final payment falls due only after you have tested the EA.
Every project is quoted in writing for your case, after the free diagnosis. A typical build takes 1 to 3 weeks once the spec is agreed.
Free diagnosis
Send your rules, .pine file or EA. Usually within 48 hours of your material, you get every gap we found and what a verified build would involve.
Written quote
Options with scope, deliverables, milestones and dates.
Contract, then milestones
Nothing is paid before a written contract.
You test it
On your own MT5, with the verification report.
Final payment
Only after the build does what the spec says.
Questions
Before you message us.
Do you promise results?
No. We build software that does what your rules say, and we show you that it does. Whether the rules make money is your strategy's question, and a backtest is a simulation of the past.
What do I send for the free diagnosis?
Whatever you have: written rules in any format, a .pine file or your EA's source code, plus the broker you use. Message us on Telegram and send the word shown on this page.
Is my strategy kept confidential?
Yes. Your rules, files and reports are used only for your diagnosis and your build. Nothing is published or reused without your written consent, and the same commitment goes into your contract. You can start with a summary of your rules and send the full detail once you decide to go ahead.
What if my rules can't be built exactly as written?
We tell you in the diagnosis, with the reason and what can be built instead. Sometimes the honest answer is that it can't, and you hear that before you pay anything.
Why not use an AI or a faster coder?
You can get code that compiles that way. What you won't get is evidence that it trades your rules and only your rules. When we converted a Pine strategy directly, it matched 280 of 637 trades. Closing that gap took measuring every trade, and it stays invisible until someone does.
Do you work from Pine or MT4?
Yes. We move TradingView strategies to MT5 with a trade-by-trade comparison, and migrate MT4 EAs to MT5. The published case is a Pine strategy. MT4 builds are checked the same way, against your own trade list.
I already run an EA. Can you help?
Yes. With its source, we can add daily and total loss limits, news windows and session rules without changing its signals, and show you, as part of the delivery, that with the limits set to neutral it takes the same trades as before. With only the .ex5, we can still audit what it does by running it in the tester and reading its history, though not why it does it rule by rule.
Who owns the code?
You get the .ex5 licensed for your own use. Source code with a transfer of rights is available and quoted in writing.
What happens after delivery?
A correction period starts on delivery, with its length in your contract. If the EA departs from the spec in that time, we fix it. Changes to your rules after that, or a rebuild for a new MT5 version, are quoted as new work.
What does it cost?
Every project is quoted in writing for your case, after the free diagnosis, with milestones you can see before you commit.
How do I know it's really you?
Our only official contact is the direct messages of @fundedengineering on Telegram. Anyone else who writes to you as us isn't us. We never ask for payment before a written contract, and never for your logins or passwords.
