This snippet demonstrates how to implement a break-even function in the ProBuilder language, which is commonly used in trading strategy development. The function calculates the break-even point for a trade, helping traders understand at what price level a trade neither makes a profit nor incurs a loss.

// Define initial parameters
priceEntry = 100 // Entry price of the trade
stopLoss = 95 // Stop loss price
targetProfit = 110 // Target profit price

// Calculate break-even point
breakEvenPoint = priceEntry + (priceEntry - stopLoss)

// Output the break-even point
RETURN breakEvenPoint as "Break-Even Point"

The code snippet above is structured to calculate the break-even point based on predefined trading parameters:

• Define initial parameters: Variables such as priceEntry, stopLoss, and targetProfit are initialized. These represent the entry price, the stop loss price, and the target profit price, respectively.
• Calculate break-even point: The break-even point is calculated using the formula priceEntry + (priceEntry - stopLoss). This formula assumes that the break-even point is reached when the gain equals the potential loss prevented by the stop loss.
• Output the break-even point: The calculated break-even point is then returned and labeled as “Break-Even Point”. This output can be used to visually confirm where the break-even price lies in relation to other trading strategy elements.

This function is essential for traders who need to manage their trades and understand the minimal favorable conditions under which they neither lose nor gain money.
