This is how a lot of pros trade. Infact almost all of the pros I know. But it's not as easy as sell the level with a tight stop. Look at the majority of pins you see. Sometimes they occur before the level. Sometimes the nose potrudes well through it. How many hit it to the tick - or even within a few ticks? Certainly some. But they are zones remember. And the problem with this strategy (hitting the level with a tight stop) is, you really need to stick to one market and know it very, very well. Because different markets move in different ways and with different characteristics. To trade this way you need to know how your market reacts to levels and what "squeezes" look and feel like.
This is the other thing about a lot of the traders I worked with. They knew their markets very, very well. I was one of very few that traded multiple markets. The vast majority traded one. Our most consistent trader who hadn't had a single losing day in three years knew his market so well he could tell you who had accumulated what, from where, where they were feeling heat and would have to puke, who was spoofing, where and why and at what times etc.
These guys picked up on things from watching closely. I'm not talking about just levels. I'm talking about market action. Price action. The S&P and YM are selling off sharply into the close but someone is buying the Dax in large lot sizes at frequent intervals. Why? Some guys that noticed this made crazy amounts of money when they found out that someone was trying to artificially hold it up and that it would sell off every morning on the open without fail. It was a pattern that lasted for a few days and then disappeared.
So, yes, studying the market as it comes into high probability turning points and watching the price action and choosing your moment is the pinnacle and it's how the pros trade. But it is certainly not easy. It is very, very hard and if you want to trade like that, cut your markets right down. To one ideally (including its related) and work, work, work at it.
