Here's a basic structure for a Pine Script strategy:

//@version=5
strategy("My Strategy", overlay=true)

// Define inputs
length = input(14)

// Calculate indicators
sma = ta.sma(close, length)

// Define entry and exit conditions
longCondition = ta.crossover(close, sma)
shortCondition = ta.crossunder(close, sma)

// Execute trades
if (longCondition)
    strategy.entry("Long", strategy.long)

if (shortCondition)
    strategy.entry("Short", strategy.short)
