It depends on the person. People with good physical tactility do this easily with practice it seems to me. I know a small few traders like myself who knock off 3-10 contract scalps all day for 1-5 ticks. We will take more if we can get it.
Dom or chart does not matter in my experience, it is the bounce of price on the right one tunes into along with obvious levels to the left.
Personalities vary wildly however being drawn to dangerous sports, climbing, racing and whatnot is 100% in the small sample I know. There is a subconscious skillset built from such, you always have a way to step back from the heat in mind (or you would be dead already).
The snag is there are low(ish) revenue ceilings with scalping? You should make money every day, only a few losing days a year (sick days) however averaging much past 8-9k a day is damned difficult (tough on the heart) and 3-5 is common as I understand from discussions with my friends.
Then once you are doing well for a couple of years, you have more capital than you can deploy efficiently scalping so swing trading becomes necessary to push through the scalping ceiling.
That might seem like good remuneration, who is complaining right? but compared to a CEO job these days? decent but not not spectacular for the effort and few if any cocktail parties. It is a lonely job. Being in the market in swings over weekends / holidays etc. is stressful to the subconscious for me anyway, I rarely relax properly. And you have to be the kind of sharp person who could be a CEO or director anyway to scalp like this as a solo retail trader. It is only one way of many to make money for the quick.
Two cents anyway. I love scalping though. I run back to momma whenever I feel lost. Once you are past building capital, its like dealing a game of patience or a 'meditation' as Sting said
