Switches among TQQQ, SQQQ, UVXY, and BIL using QQQ’s heat, trend, and recent surge. Ride uptrends with 3× QQQ, fade “too‑hot” spikes with 3× inverse, jump to volatility at extremes, and sit in T‑Bills when the trend is weak.

- First, it checks if QQQ (Nasdaq‑100 fund) is “too hot” on a 0–100 heat score (RSI>79). If yes → buy UVXY (a volatility fund that jumps when markets wobble). - Else, if QQQ is in an uptrend (above its 160‑day average): buy TQQQ (3× QQQ) unless recent gains are huge (1d>2% or 10d>15% or 100d>60%); then buy SQQQ (3× inverse). - If not in an uptrend: buy BIL (T‑Bills). Hold until rules change.

Out-of-sample: ~18.4% annualized return vs S&P ~16.9%, leveraging Nasdaq trends with smart hedges and volatility triggers. Higher upside potential with risk-managed downturn protection—though drawdowns can be larger in stress periods.
