How to open-close multiple lots on Metatrader?

Thanks in advance for everyone. My question is, how to open say 3 lots at the same time, and close say 1 lot when a target is reached and let the other lots run etc.
I am using metatrder and cant find an option to do it.

Thank you

You can open one 0.3 lot for example, and when you close, select 0.2 lots before hitting close button. You are left with 0.1 lot. Just remember, that the mt4 will always remember the last lot ammount you have selected from the pulldown menu. So be carefull

Ohh i se..How about if i want to close 1lot in a pending order? Like take profit 1 lot etc? Is it possible or must i manually do it?
Thanx
