The rules
Hold while the 50-day average is above the 200-day; step aside when it crosses below (the death cross).
- WHEN the market opens · IF not invested AND SMA(50) > SMA(200) · THEN buy with 98% of the sleeve
- WHEN the market opens · IF invested AND SMA(50) < SMA(200) · THEN sell the whole position
The most famous trend filter in markets. When the 50-day simple moving average sits above the 200-day, the asset is in a long-term uptrend and the strategy holds; when it crosses below, the strategy moves to cash. It trades rarely — a handful of signals per decade on an index — and its value is skipping the deepest bear markets, not beating every rally.
Good for: long-horizon investors who want to hold trends but sidestep multi-year bear markets.
Watch out: crosses lag badly at turning points — the strategy always gives back the first leg of a crash and misses the first leg of a recovery; choppy sideways markets whipsaw it.
Build it from blocks (or type it in English), backtest it on 5.5 years of minute data in seconds, tweak any parameter, then paper trade it on live data. No card, no broker needed to start.
