Backtest Lab.

Run any S&P 500 name through a real, rule-based strategy and see how it would have behaved over the last decade — including the drawdowns. The point isn't to beat buy & hold; it's to see how the rules manage risk.

⬡ Backtests run through 2024-12-31 (recent data is held out so results can't be cherry-picked). Trading frictions and gap-stops are modeled.

Illustrative sample — not actual trading. Read it right: similar return, far smaller drawdown — the rules sat in cash through the worst of the crashes. That downside protection is the point, not a bigger number.

⬡ How much does the "machine" actually add?

Same stock, same costs — AEGIS's full rule stack vs. the raw rules vs. the benchmarks. This is the part most tools never show you.

Illustrative sample. The full rule stack trades less, sits in cash more, and takes much smaller drawdowns per unit of return (higher Calmar) — that's the risk-management profile it's designed for.

Backtest is free.
Watching it live is the upgrade.

Backtested results are hypothetical, illustrative samples and do not reflect actual trading. Past performance — real or simulated — does not guarantee future results. AEGIS Cloud is market-data & analytics software — not investment advice, not a trading-signal service, and not a broker-dealer or investment adviser. "Strategy" here means rule-based logic (Donchian/RSI/ATR), not a machine-learning model.
