Daily, all‑in switch between tech‑heavy QQQ and gold (GLD). Uses a long‑term market trend and short‑term “heat/oversold” signals to own QQQ most of the time, shifting to gold when stocks look too hot or weak, and buying QQQ on big dips.

Each day: 1) If the S&P 500 (SPY) is above its 200‑day average, hold QQQ unless a short‑term “heat” score (RSI) on QQQ or SPY is very high (>79); then hold GLD. 2) If SPY is below its 200‑day, usually hold QQQ, but switch to GLD when QQQ is weak (below its 20‑day average) or very hot (>79). Buy QQQ on sharp sell‑offs (RSI < ~30).

Strategy rotates between QQQ and GLD using SPY trend and RSI heat signals. Out-of-sample Calmar ≈4.49 signals strong risk-adjusted performance and diversification versus the S&P 500; it seeks tech upside while hedging tops/dips.
