Seems to me the notion of "day trading" came from the dream of "sitting in front of the computer screen, making a few mouse clicks... and making bank".... you know, easy money. Turns out, not so easy.
Nevertheless, some day trading has the potential to make the effort worthwhile. (If you can learn to "trade well"... build your capital up to the point where you can day/swing 20-lots on the ES and average 2 points per day... that's $250K/year. If that's not a worthwhile goal, I don't know what is. And that's not the ultimate goal. If you can do the above, you can lever up and make multiples of $250K/year... but the key is "learning to trade well".)
but the effort is still there and a trader can trade successfully without making it; the additional profit would be welcome, but for the fact that the 'effort' is also ill health and self-enforced slavery; you are selling your hours, one hour at a time, in exchange for money; a truly talented trader surely seeks to have possession of the bulk of the hours of their life, minimising contact with 'the machine' as far as possible
obvious exceptions exist, presumably george soros - but is he really untainted by what he does? the fact is that day trading is just painful. it is mathematically impossible not to have bad days, indeed bad weeks, indeed bad months. and even the good ones are amazingly stressful, potentially, with every twist of anxiety
and automation doesn't save you, just numbs you a little; because no trader, least of all an automation-seeking trader isn't "unautistic" enough to actually not even watch or check or see what their trades are doing; knowing the trades are open is enough to have stress from them; trades which involve waiting, rather than winning a battle, those are surely the only thing a 'wizard' has time for - a 'wizard' is not, surely, supposed to be someone who wants to work rigidly many hours a day and have a routine.
but maybe i'm wrong. maybe somewhere there's a trick so easy that you can do it and be making money as unanxiously as someone investing over 3 or 6 or 9 or 12 or 15 months with modest % gain goals
we're traders to make money, not to conform to any pre-conceptions about what we're supposed to be or how we're supposed to make the money; the real rule of good trading is surely: "do very little, get loads back". and day-trading simply isn't what anyone wants to be doing when they're 80. george soros is obviously jaded.
