Why there is no system to set an order during sleeping time in advance?(529.sabzwari

i think that there are stop loss and take profit option in MT4 and other terminals and we can apply it and our positions are automatically closed on our desired prices....so i just want to know that why there is no system where we can do sitting and when price touches that point , then our desired positions are automatically placed and open....i think that if we have such a position, then forex will be more easier and we do not have to sit in front computer all the time....what do you people think?

bhai ap iske liye pending orders laga sakte hain aur wo apki kafai help karenge kiunke un mien stop loss aur take profit bhi set hosakta hai.
