// Step 1: Create a 9-period momentum indicator of the 14-period RSI
rsiValue = ta.rsi(close, lenRSI)

// Step 2: Create a 3-period RSI and a 3-period SMA of that RSI

// Step 3: Add Step 1 and Step 2 together to create the Composite Index

// Step 4: Create two simple moving averages of the Composite Index
