I$\text{'}$m currently working on developing an MQL $5$ Expert Advisor script. In this script, I$\text{'}$m implementing a functionality where I initially set the end time for a graphical object, specifically a rectangle, to the current time $($TimeCurrent$()).$ Later, I need to dynamically update this end time based on certain conditions.

In a 'Gap up$\text{'}$ scenario, if any subsequent bar closes below the lower boundary $($price$\_$dn$)$ of the rectangle, I must adjust the end time of the rectangle to the time of that bar.

Similarly, in a 'Gap down' scenario, if any subsequent bar closes above the upper boundary $($price$\_$up$)$ of the rectangle, I need to update the end time of the rectangle to the time of that bar.

Provide the updated complete code to incorporate these functionalities? Ensure all components of my current code are retained during the update process.

Donot use Chatgpt. Accuracy of the code will determine the rating. Take note of this.

My current MQL$5$ EA Script is $"$
