Systematic·Rules-based·Published live

A systematic strategy that trades in your own brokerage account.
Don't trust our backtest. Watch it trade live.

Quantastral builds rules-based strategies and publishes every trade on Collective2 as it happens. Signals execute in an account you own — your broker, your custody, cancel any month. Simulate it free for as long as it takes to convince you.

Explore Strategies How this works

No card required to watch or paper-trade. Every figure on this site is labelled as backtest or live.

How this works

You keep your account. We just send the trades.

Quantastral is not a fund and never takes custody of anything. You subscribe to a strategy, and its trades execute inside a brokerage account that stays entirely yours.

Open a free Collective2 account

About a minute, no payment details. Watch the strategy trade on paper for as long as you want before anything is connected to a broker.

Connect your own broker, once

AutoTrade routes each signal to your brokerage as an ordinary order. Monthly rebalances and daily exposure changes then happen without you.

Your money never leaves your custody

We never hold, see or touch your funds. Collective2 handles billing, and you can resize, pause or cancel in any month.

Approach

Three rules we don't break

Rules, not opinions

Every position comes from a written system. No discretionary overrides, no "feel" — which also means no quietly changing the rules after a bad month.

Risk before return

Volatility targets and regime signals size the book down automatically — before drawdowns compound, not after. Cash is a position.

Verified in public

Live records are tracked trade-by-trade on Collective2, an independent platform running since 2001. We don't grade our own homework.

The principles behind the strategy — why it stays simple, why it holds risk steady instead of bet size, and the clever ideas we tested and threw away.

Monthly memos

What the system did, every month.

A short written record of each month — what HELIOS bought, how far it levered, and what the dials were reading. Published whether the month was good or bad.

October 2, 2026

September 2026 — the first full month

The first full month: +21.6% in September and +16.6% since inception, well ahead of both benchmarks — alongside an −8.05% drawdown, a 40.6% win rate, and why five weeks proves almost nothing.
