Ilakku
A self-hosted intraday trading cockpit built around one guarantee: your broker keys never leave your machine.
At a glance: Ethereal built and runs Ilakku, its own app for active day traders. The key idea: it runs on your own computer, so your broker login never leaves your machine, unlike typical tools that keep it on someone else's server. It's proven on live trading and checked by 223 automated tests.
07The Problem
Disciplined intraday traders lack a secure execution cockpit. Typical SaaS trading tools force users to hand highly sensitive broker API keys to a third-party server — a massive security and liability risk.
Typical SaaS trading tools require handing your broker API keys to a third party.
Disciplined intraday traders lack a rule-enforcing execution cockpit that removes emotion from the entry.
Renting someone else's server means renting someone else's access to your capital.
The Solution
We engineered a hybrid SaaS: a hosted licensing control plane paired with a fully self-hosted trading engine, so broker keys never leave the user's machine. Credentials are Fernet-encrypted locally, auth uses headless TOTP, and the engine ships two strategies (ORB Retracement, R-Factor Pullback), an NSE screener across ~2,763 symbols, one-command Docker install, daily backups, and a real-time dark dashboard.
License Control Plane
A hosted plane issues and verifies licenses — the only surface Ethereal ever touches.
NSE Screener
A ~2,763-symbol NSE screener ranks the universe and feeds the day's watchlist.
Strategy Engine
Two coded strategies — ORB Retracement and R-Factor Pullback — drive every automated decision.
Self-Hosted Engine
The trading engine runs on the user's own machine; Fernet-encrypted broker keys never leave it.
automated tests passing
A 49-symbol live universe runs against real broker tokens.
Daily encrypted backups keep every install restorable.
Broker API keys never leave the user's machine — full stop.
Every stored credential is sealed with Fernet encryption.
Broker sessions authenticate via headless TOTP with no manual OTP handoff.
A single Docker command stands up the whole self-hosted stack.
The database backs up automatically every night.
A dark, info-dense dashboard streams positions and signals live.
The Outcome
Broker-key isolation as a core security guarantee — verified with 223 automated tests passing and a 49-symbol live universe running against live broker tokens.
