How It Trades
- Compute three weighted moving averages over 7, 20 and 50 bars.
- Buy when they stack bullishly: fast above mid above slow. The 7-bar leader makes this the fastest of the stack strategies: earlier entries, at the cost of more false starts.
- Sell when the fast average drops back below the mid.
