How It Trades
- Measure two trailing returns each bar: a quarterly one (90 bars back) and a yearly one (252 bars back), a fast clock and a slow clock for the trend.
- Buy only when both are positive: the market is up versus last quarter and versus last year, so the short and long views agree the trend is real.
- Sell as soon as either turns negative: one clock disagreeing is enough to step aside. Requiring agreement enters later than a single-window momentum strategy but avoids trades where a short rally fights a longer downtrend, or an old uptrend is already rolling over.
