This ProBuilder code snippet calculates the body of a candlestick as a percentage of its total range and classifies it based on a specified threshold. The result is used to determine if the body’s percentage is less than or equal to 20%.

level = 20
perc = (abs(close-open)/range)*100
result = 0
if perc <= level then
    result = 1
endif
return result

This code snippet is designed to help users understand how to compute relative sizes within a dataset, in this case, financial candlestick data. Here's a breakdown of how the code works:

• Variable Initialization: The variable level is set to 20, which acts as the threshold percentage.
• Percentage Calculation: The variable perc calculates the absolute difference between the close and open prices of a candlestick, divided by its range (high minus low), and then multiplied by 100 to convert it into a percentage.
• Result Initialization: The variable result is initially set to 0.
• Conditional Logic: An if statement checks if perc is less than or equal to level. If true, result is set to 1.
• Output: The result is returned, which will be 1 if the body's percentage is less than or equal to 20%, otherwise 0.

This example is useful for understanding conditional statements and basic arithmetic operations in the ProBuilder language, particularly in the context of analyzing financial data.
