Close automatically at the same time that I established the expiration date when creating the trade

Hello,

I am looking for a solution so that my trades are automatically closed at the same time that I established the expiration date when creating the trade.

An example, if I established that the expiration date for a new trade was on 01/23/2019 at 2:00 p.m. and the trade opens, i want it to close the same date and time that I established as expiration (regardless of whether there are losses or gains).

Can anybody help me?

I also need to know how to implement the code.

Best regards
