One focused product for gold traders
Retail gold traders are buried in generic tools built for every market. Gold (XAUUSD) moves on its own drivers: the US dollar, real yields, central-bank flows, London and New York sessions, and high-impact data releases. The brief was to build one focused product that:
- Explains what gold is doing and why, in plain English
- Connects to real broker accounts safely
- Keeps the trader in control, with risk controls that cannot be bypassed
- Works on desktop, mobile web and a native Android app
- Pays for itself through subscriptions, with costs kept under control
Five principles we built on
Narrow and deep
Gold only. Every feature, data source and AI instruction is tuned to one instrument.
Safety first
Every order goes through one guarded route. When a check fails, the order is blocked, never allowed through.
AI with boundaries
The AI analyst separates known facts, calculations and its own interpretation, and never places trades on its own.
Measure everything
Funnel, ad and engagement tracking from day one, so product decisions follow real data.
Ship weekly
Run as a live product, not a one-off project.

Six systems, one team
Max, the AI gold analyst
- Chat with threaded conversations, folders and search
- Live market context: price, sessions, economic calendar and the user's own positions and journal
- Chart reader: upload a chart screenshot and get a structured, advisory read
- Trade and journal review, risk and position-size maths
- Voice mode
- Usage metering: monthly reply allowance enforced on the server (free and paid tiers)
- Consistent persona and branded identity across app, emails and film
Trading infrastructure
- MT5 broker connectivity through MetaAPI: provisioning, sync and multi-account positions
- Automatic handling of broker symbol differences (e.g. XAUUSD vs XAUUSDm)
- One central order route enforcing fail-closed daily P&L limits (London trading day), per-account kill switches and circuit breakers, duplicate-order protection, mandatory position caps, and momentum and regime blocks
- Hash-chained decision ledger for AI model decisions (tamper-evident audit trail)
- Cost control: broker connections need a paid plan, with automatic notices and clean disconnection that keeps history
Android app (live on Google Play)
- Capacitor-based native shell, published as "Gold Hunts: Gold Trading App"
- Native animated splash, adaptive icons, biometric app lock
- Push notifications with preferences, quiet hours and dedupe
- Google Play Billing with server-side verification and real-time developer notifications
- Repeatable versioned releases through Play Console
Web platform
- Modern full-stack React (TanStack Start) running on the edge
- Stripe subscriptions on web, Google Play on Android, both resolving to one entitlement
- Desktop trading desk, mobile web experience and public site
Data, content and growth engine
- Around 258 search-focused public pages: calculators, education, research and data studies
- Gold economic calendar with AI-written gold impact briefs
- Session edge map and market-hours and holiday engine
- Cross-platform signup funnel tracking (web, mobile, Android) with live admin alerts
- Meta Conversions API, ad-link attribution and per-ad spend matching
- Automated nurture email sequence and a branded transactional email system
- Live user presence analytics and a daily Google Search Console intent digest
Governance and security
- Role-based access with a strict super-admin back office
- Row-level security on user data
- Consent-gated email, with per-type preferences honoured by every sender
- Dedupe ledgers so no customer gets the same alert twice
Live on Google Play
The trader stays in control
- Traders stay in control. Max is advisory, can be wrong, and never places a trade on its own.
- Every order passes one guarded route; if any check fails, the order is blocked.
- Daily loss limits, kill switches and position caps cannot be bypassed from the app.
- AI decisions are written to a tamper-evident ledger for review.
- Copy separates known facts, calculations and AI interpretation.
