Daily rotation among 3× US stocks (UPRO, TQQQ), 3× long Treasuries (TMF), or T‑Bills (BIL) using volatility filters, a simple momentum gauge, and buy‑the‑dip rules to ride calm uptrends and step aside when markets turn rough.

Each day it checks if markets are calm (past 14–42 days volatility under set caps). If calm, it “surfs” between 3× S&P 500 (UPRO) and 3× Nasdaq‑100 (TQQQ), favoring the one with stronger recent momentum (RSI = a simple recent‑strength gauge) and sizing them by recent volatility. If markets are jumpy or in a bigger sell‑off, it moves to T‑Bills (BIL) or uses buy‑the‑dip rules (enter 3× funds only after ~−5% 5‑day drops; don’t chase if a 1‑day +5% spike just hit). In healthy phases it may run ~55% UPRO/TQQQ + 45% 3× Treasuries (TMF). Rebalanced daily.

Out-of-sample: ~50% annualized return vs SPY ~22%, with Calmar ~1.0. Dynamic 3x equity exposure and Treasuries/cash aims to ride uptrends and curb risk, offering higher upside than the S&P—note larger drawdowns in crises.
