For me because I'm not online all day and I have an offline work. What I do is set the price I want to sell. And I'm looking at it when I'm home tonight. There is also a win.
Good strategy, the only drawback is that you need to keep the money in the exchanges instead of the wallets...
it is always feels good that when you come back to check the exchange account the orders are all filled. you don't need to worry about the ups and downs by placing these orders
