Object over and under price

[timmyhanke]

My idea is to draw two lines , one above price with x pips and one below price with x pips , and if price goes above the upper line it buys and when it goes below the lower it sells.
I made it so far .

But when for example the buy trade is triggered i want it to delete the upper line and make a new one yet again x pips above price .
But is there a way to check if the object isnt there and then make a new one , have it to once per bar but its now what i wanted
