Systematic · Automated · Self-directed

Two dozen ideas went in.
One came out.

Tydal runs a single strategy — the one that survived everything we threw at it. Decades of history. Independent markets on three continents. Real execution costs, measured rather than assumed. Everything else we tested died, and we kept the receipts.

A rule, not an opinion

The same decision every session, placed on a schedule by software. No forecasts, no overrides, nothing to second-guess at 3am.

Your account, your money

It connects to your own brokerage with API keys that can trade but never withdraw. Encrypted, revocable, and yours to switch off.

Proof, not promises

Every fill is checked against the official exchange price. Execution quality is a number on your dashboard — not a claim on a website.

Why it holds up

The edge isn't a prediction, and it isn't a pattern we curve-fitted into existence. It's structural — which is why it still works decades after it was first documented, and why publishing it hasn't killed it. What it is, and how it's traded, is for account holders.

How it works

  1. Connect your brokerage account with trade-only API keys.
  2. Set your size — you choose the allocation and can change it any time.
  3. Arm it. The scheduler runs every trading day and handles market holidays and shortened sessions on its own.
  4. Watch equity, positions, and execution quality update as it trades.
Not investment advice. Tydal is self-directed automation software: you choose whether to run it, in your own account, at your own risk. Systematic strategies lose money in some periods — including double-digit drawdowns — and past performance never guarantees future results.
