Quantastral builds rule-based strategies and runs them in the open on Collective2 — every trade timestamped by a third party, every drawdown on display.
Fully systematic, rebalanced on schedule, and published only once we run it live ourselves.
Holds the 20 strongest US stocks, sized by two dials — market breadth and a volatility target. Levers up in healthy tapes, steps toward cash when conditions break.
Growth of $10,000 · hypothetical backtest, 2020 – Aug 2026
*Hypothetical backtest at a 1.5× leverage cap, gross of costs. Full disclosure below.
Every position comes from a written system. No discretionary overrides, no "feel" — which also means no quietly changing the rules after a bad month.
Volatility targets and regime signals size the book down automatically — before drawdowns compound, not after. Cash is a position.
Live records are tracked trade-by-trade on Collective2, an independent platform running since 2001. We don't grade our own homework.
Takes about a minute. No payment details needed to watch or simulate.
See every rebalance, every position, every leverage change as it happens — with nothing at risk.
When the live record has convinced you, mirror it automatically at the size you choose. Your funds never leave your custody. Cancel any month.
