The short answer
There are two ways to build a trading strategy with AI today.
- The AI writes the code. A language model turns your words into MQL5 for MetaTrader 5 or Pine Script for TradingView. Then you, or a compile loop, check that code. General chat assistants, the assistants built into MetaEditor and TradingView, and several Pine Script tools work this way [2][1][3].
- The AI fills a form, and tested generators write the code. This is how AlfaTactix works. Tactix Studio, our AI, fills the same 7-step form you can fill by hand. You read the strategy in plain words and save it yourself. The code then comes from our MQL5 and Pine Script generators, and those have a test record.
The first way is more open: it can try any idea the language allows. The second is narrower, but you can check it without reading code. For example, all 29 golden Expert Advisors from our generators compiled in MetaEditor with 0 errors and 0 warnings.
Neither way tells you whether a strategy will do well in the market. This page compares how the code is made and what you can check. It does not compare results.
Two ways to build a strategy with AI
AI that writes the code
You describe a strategy in a chat. A language model writes the program: an Expert Advisor in MQL5 for MetaTrader 5, or a Pine Script for TradingView. You get source code, and you can ask for any change.
What happens next depends on the tool. With a general chat assistant, users describe copying the code into MetaEditor, compiling it there, and pasting the errors back into the chat [9][11]. Newer tools close part of that loop themselves. LuxAlgo Quant fixes errors in code it wrote [3]. PineGen AI states that it checks its code against TradingView's v6 compiler before you see it [6]. Pineify's agent can use syntax diagnostics when they are available and enabled [4]. The platforms now have their own assistants too: MetaEditor's AI Assistant since MetaTrader 5 build 6060, released on 23 July 2026 [2], and TradingView's AI Copilot [1].
In every case, the model writes the program. A new request can give new code, and checking what that code does is your job.
AI that fills a form
AlfaTactix puts the AI one step earlier. Tactix Studio reads your message and writes a short list of changes to the strategy: the same fields you fill in the form. The server applies them with the same library as the form and checks them with the same validator. Studio never writes code and never saves. You check the strategy on Studio's sheet and save it in the form. More on how Tactix Studio works.
The code is written afterwards by our generators, for the platform you chose in Step 1: MetaTrader 5 or TradingView. A strategy you build by hand and a strategy Studio fills go through the same generators. More on how the generators are tested.
We are not the only tool that keeps the AI away from most of the code. EA Builder's AI edits a validated configuration over a runtime that was tested in advance, but it still writes some small functions itself [7].
The comparison table
The first table compares the two designs. The second names tools and says what each vendor states on its own page. We read every page. We did not test these products ourselves.
The two designs side by side
| AI writes the code | AI fills a form (AlfaTactix) | |
|---|---|---|
| Who writes the code | A language model, for each request | Our generators; the AI writes no code |
| What the AI can build | Anything the language allows | Only what the form offers: 47 indicator types, up to 3 timeframes, up to 8 filters |
| Can the code call a function that does not exist? | Users report that it happens [9] | The AI writes no code, and it never writes a value the form's schema refuses |
| Compile check | Depends on the tool: none in a plain chat, a compile loop in some tools [3][6][7] | 29 of 29 golden Expert Advisors with 0 errors and 0 warnings in MetaEditor; every Pine Script we checked with 0 problems in the Pine Editor |
| Can the same request give different code? | Yes: a language model writes the code again for each request | The AI can read you differently, but the strategy you save is what counts: the code generators are fixed programs with no AI model inside, and the same strategy document and the same generator release always produce the same file, byte for byte |
| Can you read the code? | Yes, you get the source | Yes: no platform indicator built-ins, every indicator is written out in the file |
| What you check | The code, and what it does | The strategy, in plain words, on Studio's sheet and in the form |
| To change a stop or a period | Ask again, or edit the code | Change the field in the form; no AI needed |
| Platforms | Whatever the tool supports | MetaTrader 5 (MQL5) and TradingView (Pine Script v6); no MetaTrader 4 |
Tools that use AI, by name
| Tool (platform) | Who writes the code | Checks the vendor states | Source |
|---|---|---|---|
| General chat assistants, for example ChatGPT or Claude (any platform) | The model writes the code in the chat. | Users describe compiling it themselves in MetaEditor and pasting the errors back. | [9][11] |
| MetaEditor AI Assistant, build 6060 (MetaTrader 5) | Generates MQL5 programs, analyses code, finds errors and suggests fixes, helps refactor. | The release notes do not say that it compiles the code for you. | [2] |
| TradingView AI Copilot (TradingView) | Writes, edits and saves scripts; indicators and strategies are applied to your chart. | Its help page lists checking scripts and reading strategy reports. A paid add-on. | [1] |
| LuxAlgo Quant (TradingView) | Writes Pine Script that you can open and edit. | Sees runtime errors and fixes errors in code it wrote; a one-line backtest summary for strategies. | [3] |
| Pineify (TradingView, MetaTrader 5 and others) | An AI coding agent writes Pine Script; MQL5 source too. | Syntax checks give the agent diagnostics when they are available and enabled; the MQL5 page calls the output a draft to review and test. | [4][5] |
| PineGen AI (TradingView) | Writes Pine Script v6 from a prompt. | States that the code is checked against the TradingView v6 compiler before you see it. | [6] |
| EA Builder (theeabuilder.com) (MetaTrader 5) | A hybrid: the AI edits a validated configuration and fills small functions; a pre-tested runtime does the rest. | A loop compiles in MetaEditor and fixes the AI-written functions, up to 3 rounds. | [7] |
Each row says only what the vendor's page states, or, for chat assistants, what users report. Prices and plans change, so they are not in this table: see each vendor's page.

Why "it compiles" is not "it does what you said"
A compiler checks that the code is valid MQL5 or Pine Script. It does not check that the code does what you asked. A strategy can compile, run, and still read the wrong bar, compare a value with itself, or never open a trade.
A compile-and-fix loop, which several tools now run [3][6][7], answers the first question: is this valid code? The second question stays with you: does it do what I meant?
What users and researchers report
These are reports by others, each with its source. We did not measure them, and they are not about any one product.
- In December 2022, TradingView wrote that GPT-written Pine Script was unreliable: it often did not compile or did not do what was asked. It stopped taking requests to fix such code in its Q&A forums [8].
- In a thread started in March 2023 on the MQL5 forum, a moderator listed typical errors in ChatGPT-written code: MetaTrader 4 calls in MetaTrader 5 code, functions that were never defined, and two OnInit functions in one program [9].
- In May 2025, a user asked why an EA placed no trades; fixes from ChatGPT and Claude had not helped [10].
- In a test published in May 2026, a ChatGPT-written EA needed three rounds of fixes, about 35 minutes, before it compiled, and one fix added new errors. Then an RSI cross compared the value with itself, so the EA made only 2 trades in 12 months. The author sells his own tools [11].
- A January 2026 guide counts about twelve choices that a one-line RSI prompt leaves the model to guess. It also shows how a higher-timeframe call with look-ahead lets a backtest use later prices [12].
- A benchmark of 400 tasks, published in April 2026, found that the main limits of current models are not syntax but turning trading logic into correct code [13].
Where we put the risk
Studio can misread you too. Its feature groups switch on at 90% or more of the facts right, not 100%. What changes is where a mistake shows up and who can see it:
- A misreading shows up in the form, in plain words. Studio's sheet lists your strategy line by line and marks the values it assumed as "Assumed". Each line opens its field in the form. You fix a wrong value by changing a field, not by debugging code.
- Code decides when to ask. Studio asks at most 3 questions a turn, chosen by code, not by the model. When code sees a mismatch, a second model call compares your words with the strategy.
- Nothing is filled in silently. If you ask for something the builder does not have, Studio says that it is not available yet and writes nothing in its place.
- The code side is tested once, for everyone. The same generators turn every form into code, and that translation is what our tests check: indicator values bit for bit, clean compiles, the same signals as the MetaTrader 5 tester. The next section has the numbers.
How we test our side
If the AI only fills a form, the code is only as good as the generators. So the generators carry the test record.
| What we checked | Result |
|---|---|
| Indicator values on MetaTrader 5, against our reference library | 1,159 of 1,159 equal bit for bit |
| Indicator values on TradingView | 461 of 461 equal, with zero tolerance |
| The 47 indicator types | All covered by exact test values on both platforms: 29 types in the first set, 16 in the second, the candle and swing patterns in the rule tests |
| Expert Advisors compiled in MetaEditor | 29 of 29 golden EAs: 0 errors, 0 warnings |
| Pine Scripts in TradingView's Pine Editor | Each script we checked: 0 problems. Each check was a manual run, so there is no single total |
| The same strategy, generated twice | The code generators are fixed programs with no AI model inside. The same strategy document and the same generator release always produce the same file, byte for byte |
| Signals against the MetaTrader 5 tester | The same on 29 of 31 golden strategies; the other 2 are strategies MetaTrader cannot run, and we refuse to generate them |
| Restart, crash or removal from the chart | The EA recovers with the same trades as a run without the restart (MetaTrader 5 tester) |
| AI feature groups | A group is switched on only after 3 live runs out of 3 meet every threshold; all 8 groups are on |
| Every change to the product | Tested on its exact commit: 516 recorded test results; the last run of both test suites passed 8,770 backend and 2,165 frontend tests |
What these figures show: the code does what the strategy in the form says. What they do not show: how a strategy would do in the market. Whole backtests are not equal bit for bit either: trades are equal, or differ for a named, listed cause. And nothing was tested on a live account.
The full record is on How we test the AlfaTactix strategy builder. The generators have their own page, and so does Tactix Studio.
When another tool may suit you better
We built the form-first design so that you can check a strategy without reading code. It does not fit every need.
What the other approach does well
- Any idea. A model that writes code can try anything the language allows: your own indicator, unusual order handling, logic no form has a field for. Our builder can only build what its form offers.
- Speed for small things. A quick indicator to look at on a chart can take one message.
- You already write code. If you read MQL5 or Pine Script, an assistant inside MetaEditor [2] or TradingView [1] works where you already work, and you can review every line yourself.
- Some tools now check their own output. Compile loops, fixes for runtime errors and backtest summaries are part of several tools [3][6][7].
Our limits
- Only what the form offers: 47 indicator types, up to 3 timeframes, up to 8 filters, and the builder's exit and risk blocks. Studio calls anything else "not available yet".
- Two platforms: MetaTrader 5 and TradingView. No MetaTrader 4, and no other platform.
- The last AI feature group passed only with Studio's first-choice models: the advanced operands (slope, between, near, arithmetic, previous-period values, the session range). Studio may fall back to other models when those do not answer, so check these parts on the sheet with extra care.
- The AI is not perfect: a feature group opens at 90% or more of the facts right, not 100%. That is why you check the sheet and save it yourself.
- No live trading test: every run in our record is a MetaTrader 5 tester run or a TradingView backtest.
- We did not test the other tools. This page describes their design and what they state about themselves.
For rules the form cannot express, a block builder is one option: fxDreema alternative compares fxDreema, where you connect blocks, with the AlfaTactix form.
Questions and answers
Does Tactix Studio write MQL5 or Pine Script code?
No. It fills the strategy form. The code always comes from the same generators as a strategy you build by hand.
Can I trust code that a chat assistant wrote?
Check it as you would check code from a stranger: compile it, read it, and test it in the MetaTrader 5 tester or in TradingView before you use it. TradingView and members of the MQL5 forum have reported code that did not compile or did not do what was asked [8][9][10].
Is Tactix Studio always right?
No. A feature group is switched on only when 3 live runs out of 3 get at least 90% of the facts right and meet the other thresholds. Every value Studio sets shows on its sheet, the values it assumed are marked, and nothing is saved until you save it.
Can I read the code AlfaTactix generates?
Yes. The code uses no platform indicator built-ins: every indicator is written out in the file, and every file names the generator version in its header (version 1.0.0). Which plans include the download is on the pricing page.
Does it support MetaTrader 4?
No. The builder generates MQL5 for MetaTrader 5 and Pine Script v6 for TradingView.
Will Studio build a grid or martingale strategy?
No. The builder has neither, and Studio never sets risk above 10% of the account per trade.
Does a clean compile mean a strategy will do well?
No. A clean compile and our parity tests show that the code does what the strategy says. They say nothing about results in the market. Studio builds the rules you describe; it does not search for strategies that do well.
Did you test the other tools on this page?
No. We read their public pages and report what they state. The user reports come from public forums, blogs and one research paper, each listed under Sources.
Can I try it without signing up?
Yes. The public demo shows a recorded example of Studio building a strategy from one sentence (no model is called in the demo), next to the same form you fill in yourself.
