I trade intraday fluctuations with my own money, and my advice is to stay away. I've become a psychotic retard with no desire to socialize. The money means nothing now that my soul is sucked away. Once you find an edge, and properly manage trades, there is no end to how much data you can analyze. You can have many profitable variations of an approach, but your optimal zones constantly shift. You end up becoming a data scientist. I run a nearly fully automated operation with endless hours of input entry and data priming. One machine trades and ten others run automated data entry tasks round the clock.
Wow...you sound like you're stuck in the "twilight zone".
If any type of trader loses their desire to socialize, they've most likely stopped or decreased doing other things that are a key element to happiness.
I truly believe unhappy traders that stay as such...year after year....they will not last beyond several years even if they are profitable. So yeah, you can be profitable and still be very unhappy just like any other job that people do to make money but are unhappy. Worst, it starts to impact your health...mind and body.
That's another issue traders (including day traders) don't really talk about. If day trading, swing trading, position trading, long-term trading, scalping or whatever is taking away the things that makes you happy or keeps you feeling normal sort'uv speak...
Its best to just walk away from it and find something else to do or get psychological help to find some kind'uv peace with whatever it is that you're doing.
