Verdict

REJECT

Fails on real spreads

A good backtest can still be overfit, cost-blind, or tied to one market period.

A promising result is a reason to test further, not proof that an EA is ready for live use.

Illustrative test pathNot Operator test data
  • A strong in-sample result is only a starting point.
  • Spreads and costs can change the result.
  • A different market period can expose fragility.

From AI-generated idea
to a tested deployment decision

One sequence checks the code, the data, and the assumptions before you decide whether to run an EA.

This is an illustrative animation, not a live or recorded Operator run.

  1. Stage 01

    Research

    Start with your rules or explore a strategy hypothesis.

  2. Stage 02

    Build

    Turn the written strategy rules into an MQL5 EA.

  3. Stage 03

    Optimize

    Test parameter choices against your broker's real ticks.

  4. Stage 04

    Break

    Check whether results hold up outside the optimization sample.

  5. Stage 05

    Risk

    Stress costs, spreads, and drawdown before a deployment decision.

  6. Stage 06

    Deploy

    Review the evidence and decide what, if anything, to run next.

A decision aid, not an auto-trader

Build the idea with AI. Make it earn your confidence through evidence.

Operator helps you review a strategy. You decide whether to deploy it, and no test can promise future results.

Illustrative example

A promising EA can fail its next test.
That is the point of testing it.

This scenario shows how a strong optimization result can weaken under other years and tougher cost assumptions. It is not a recorded Operator run or performance proof.

Illustrative tester verdict

Example assessment: unsafe for live capital

Example reasoning: in-sample performance can be an artifact of regime overfitting, and real-tick decay can exceed risk thresholds.

REJECT
Example revision workflow

A rejection can identify what to review next.

This illustrative review attributes losses to slippage on wide spikes and proposes possible follow-up checks; it is not a result claim.

1. Tighten regime gating

Example: filter trades when ATR exceeds 1.2x baseline.

2. Revise exit management

Example: compare ATR-bar stops with a fixed take-profit.

3. Automated re-sweep

Example: re-run a Tester check on a revised specification.

Planned Operator workspace
Delivery is not available yet

The workspace ZIP has not been published or asset-checked, so checkout and delivery remain unavailable.

  • Operator Workspace: START_HERE.md, 9 skills, broker data, templates
  • The complete PivotReaction example run, uncut
  • 3 pre-filled strategy templates: London Breakout, Trend Pullback, Asian Range Mean-Reversion
  • setup.bat one-click prerequisite and MCP check
  • Strategy Spec Prompt + 7-Point Backtest Kill Checklist
  • Edge PDFs: Competition Access; Challenge-to-Payout Guide; Alternative Capital Method
  • Deployment Fit and Prop-Firm Fit skill, unlocked
  • 12 months of live workspace updates
  • An isolated user/ folder that updates never overwrite

You do not need to write MQL5 by hand.

Describe the rules in plain English or start from a template. Your AI agent drafts the EA; you still review its logic and test results before deciding whether to trade it.

Frequently asked questions

Operator is not available for checkout or workspace delivery yet.

The workspace ZIP is not published and verified yet, so there is no Operator checkout to open. The questions below still describe what the product does and does not cover.

Yes. You can ask an AI agent to write MQL5 from your rules without buying Operator.

Operator is for traders who want a repeatable research, build, and testing workflow instead of stitching prompts and checks together themselves.

The final word
One workspace for the full EA review, from written rules to a final verdict.

The planned €297 workspace includes 9 skills, 3 templates, and a full example run. Checkout opens only after the delivery ZIP passes release checks.
