CLOSE ORDER SCRIPT

I want to know if it is possible to create a script that closes open orders at the same time. For example, I have 20 open orders opened at the same time, and want to close ALL the orders at same time. I have tested SEVERAL scripts , and ALL closes the orders ONE BY ONE, they are not closed at same time. It is possible ?

In the video below, you can see what all scripts usually DOES and I DONT want : close order by order.

If you have dozens of orders, it will take seconds or minutes to close all.

Thanks
