You are not waiting for the ATH before selling? I think we all could see it when its overbought already which if you wait for it, you can maximize the profit.
But why do you have to make it a ladder, is there any special about it where you will buy back every time price dips? I have no idea how this strategy works for you. Although I wanted to sell and wait for anther dip, the dip isn't enough as deep.
