Multi-asset trend following
Hold only the asset classes in an uptrend, sized by trend strength divided by variance, which maximises the Sharpe ratio if correlations are ignored.
Edit anything; the result updates as you type. Lines like window = 20 become sliders.

Multi-asset trend following (4.6)
Hold only the asset classes in an uptrend, sized by trend strength divided by variance, which maximises the Sharpe ratio if correlations are ignored.
Key equation
Lab formula
r = close / delay(close, 252) - 1
keep = (r > 0) && (close > sma(close, 150))
vol = stddev(returns, 63)
scale(keep * r / vol ^ 2)How the backtest works
The formula is evaluated for every asset on every day. Its values become positions at that day’s close, using the portfolio rule you pick, and earn the next day’s close-to-close return. Costs are charged in basis points on the amount traded. Everything runs in your browser on daily data from Yahoo Finance, adjusted for splits and dividends.
