This is a dumb question, but I was just wondering. Suppose you are using the same account on both MT4 and MT4 mobile, but you left your computer on running MT4 then you leave to go outside for a walk or dinner.

You decide to check your mobile for the status and decides to close the position. Is it possible to close it while the MT4 on your computer is still on?

Another thing. After setting your SL, TP and trailing stop, you shut down MT4, will the SL, TP and trailing stop still be activated upon hitting your target on the broker's server?

Patience with me, I'm a newbie.
