This code snippet demonstrates how to implement a robustness tester for trading strategies based on conditional trading days, months, and years using the ProBuilder language. The purpose is to test the strategy under various temporal conditions to assess its performance consistency.

Explanation of the Code:

• The code starts by defining variables to determine whether the current day, month, or year is odd or even.
• A variable tradeon is initialized to 0 (false). This variable will control whether a trade should be executed based on the specified conditions.
• Multiple conditional statements check the value of choice (which is set during optimization) to determine under which conditions trades should be executed. For example, if choice is 1, trades will only be executed on odd days.
• Each condition modifies the tradeon variable to 1 (true) if the current date matches the criteria set by the choice variable.
• This setup allows the strategy to be tested under various combinations of day, month, and year conditions to evaluate its performance across different temporal segments.
