Workfusion Trading AI

Workfusion Trading AI is a SaaS MVP for MT4/MT5 automation builders.

It helps traders:

• Generate EA drafts from plain-English strategy ideas.
• Debug MQL4/MQL5 code and compiler errors.
• Govern prop-firm payout readiness with target, drawdown, trading-day, exposure, and warning checks.
• Analyze trading reports and identify risk issues.
• Export PDF governance reports before changing risk or requesting payout review.
• Optimize prop-firm settings before demo or live testing.
• Download generated code artifacts.
• Save projects through a local storage adapter.
• Pre-check generated code, optionally compile MT5 .mq5 files through MetaEditor, and estimate backtest readiness.
• Prepare Stripe/PayPal billing with explicit live-mode guardrails.

Product Positioning

Workfusion is a software tool. It does not manage accounts, execute trades, custody funds, or guarantee profits.

Core offer:

Generate, debug, and risk-check MT4/MT5 Expert Advisors for prop-firm traders.

Updated offer:

Build, debug, and govern MT4/MT5 automation.

Local Development

npm run dev

Open:

http://localhost:3000

Verification

npm run lint
npm run build

Optional Real MT5 Compiler

POST /api/workers/compile always returns a static MQL pre-check. To make it run a real MetaEditor compile on a Mac/VPS with Wine and MT5 installed, set:

WORKFUSION_COMPILER_WORKER_URL=http://127.0.0.1:8787
WORKFUSION_COMPILER_WORKER_TOKEN=change-this-long-token
WORKFUSION_METAEDITOR_ROOT=/path/to/MetaTrader 5
WORKFUSION_WINE_BIN=wine
WORKFUSION_METAEDITOR_TIMEOUT_MS=180000

Start the Mac/VPS worker:

npm run compiler:worker

The worker root folder must contain MetaEditor64.exe. When configured, the API posts the submitted .mq5 to the worker, the worker writes it into MQL5/Experts/WorkfusionCompilerJobs/, calls MetaEditor, and reports whether an .ex5 artifact was produced. Vercel deployments normally run in static_precheck mode until WORKFUSION_COMPILER_WORKER_URL points to a reachable HTTPS worker endpoint. If WORKFUSION_COMPILER_WORKER_URL is not set, the API can still run local MetaEditor compilation directly via WORKFUSION_METAEDITOR_ROOT.

PayPal Sandbox Test

Use sandbox credentials only:

PAYPAL_API_BASE=https://api-m.sandbox.paypal.com
PAYPAL_CLIENT_ID=...
PAYPAL_CLIENT_SECRET=...
NEXT_PUBLIC_PAYPAL_MONTHLY_PLAN_ID=...
NEXT_PUBLIC_PAYPAL_YEARLY_PLAN_ID=...
PAYPAL_WEBHOOK_ID=...

Then run:

npm run paypal:sandbox -- preflight
npm run paypal:sandbox -- create sandbox-buyer@example.com starter
npm run paypal:sandbox -- verify I-SUBSCRIPTIONID

Premium activation is completed by /api/billing/paypal/activate after PayPal redirects back with subscription_id. Renewals and payment receipt evidence are handled by /api/billing/paypal/webhook, which verifies PayPal webhook signatures and records PAYMENT.SALE.COMPLETED events.

Launch Checklist

• Connect Stripe price IDs or PayPal order capture before public paid launch.

• Add user accounts and persistent project storage.
• Use a dedicated Mac/VPS compiler worker before marketing browser-only SaaS outputs as guaranteed production-ready.
