This ProBuilder code snippet demonstrates how to calculate the performance of a Buy & Hold strategy over a specific period. The code calculates the percentage change in the price of a stock or asset from the beginning to the end of the data series.
once startPrice = close[0]
once endPrice = close
return = (endPrice - startPrice) / startPrice * 100
This snippet is structured to calculate the return of a Buy & Hold investment strategy using the following steps:
- Initialization of Variables: The once keyword is used to assign the closing price of the asset at the start of the data series to startPrice, and the current closing price to endPrice. This ensures that these variables are set only once and do not change with each new bar of data.
- Calculation of Return: The return is calculated by subtracting the startPrice from the endPrice, dividing the result by the startPrice, and then multiplying by 100 to get a percentage. This formula gives the percentage change in the asset’s price over the period.
This example is useful for understanding how to use variables and basic arithmetic operations to analyze financial data in ProBuilder.
