A simple, two-layer “surf the wave” strategy: in calm markets, buy the most oversold levered equity proxy (UPRO or TQQQ) based on a 21-day RSI; guard the choice with a volatility check derived from SPY; if volatility is too high, switch to SHY. No regular rebalancing, one-asset-at-a-time exposure, and a built-in damping to reduce noise.

What it does in plain language: - It watches three investments: UPRO (3x S&P 500), TQQQ (3x Nasdaq), and SHY (short-term Treasuries). - For each, it prints a 21-day RSI value. The asset with the lowest RSI (the most oversold recently) is the candidate to own. - Before you buy, it checks recent volatility. It looks at SPY price moves to estimate how wild the market has been, and combines two volatility checks (think of them as two “speed limits” at 1% and 2%). If volatility is low enough (below the thresholds), it proceeds with the chosen asset; if volatility is too high, it instead holds SHY (the safer option). - When a signal fires, it allocates cash equally but, in practice, selects just one asset (the one with the lowest RSI). So you’re effectively “all in” on that asset rather than spreading across multiple assets. - The system does not rebalance on a fixed schedule. It uses a small corridor to avoid whipsaws and change signals only when the risk-and-signal thresholds are met. - The intended behavior is to catch rebounds from dips in leveraged equity proxies during calmer markets, while stepping into a safer bond proxy when volatility ticks up.

Out-of-sample, this strategy targets far higher upside than the S&P 500 (≈47% annualized) with a disciplined volatility gate and single-asset focus. Expect larger drawdowns (≈55%), but Calmar ~0.85 and Sharpe near 1 balance risk and reward.
