Practise which aspect? Chart reading and TA or risk mgmt, cuz there are many aspects that makes someone a successful trader.
start trading, (on paper or on small account) you want to buy something buy something, you want to sell something sell something eventually you will feel unsatisfactions with your actions start looking for answers, read books, ask at forums etc, but be careful - those answers are just tips, continue trading.. new questions will arise, again look for answers around you then the time will come when you stop looking around, when you will start looking within this the time when you are ready to fill your tabula rasa salvation lies within
Adopt a fast feedback loop. Observe the market in it's basic granularity. Build your distinctions through deduction. Log your observations as per your trading timeframe. Debrief the day. What you first identify as 'noise' can eventually become signal. Few ever do the work required to do this. At some point what was once impossible becomes possible. Beliefs form perception. To increase one's perception, eventually, one will have to examine their beliefs around how markets actually function to get to the truth of the matter. Price migrates, volume leads price, etc. Many a distraction you will encounter of those whom never do the work required. Instead they complain and bray. The fact that you are paying attention to 'things that you didn't know that can be knowable' is the right direction. That information can come through a variety of ways, even books, youtube, educators, forum posts, etc. One can know a thing by knowing what it is not. As you build your capacity for discernment, so to will your capacity to extract the market's full offer.
your name is gamble it all how will you ever become a successful trader the definition of trading is not gambling
I don't think its a qualification required for trading but most trading firms afaik prefer math/comp sci students if they are recruiting for jr positions.
there should be one qualification, can you make money. maybe your goals are too low, not a prop shop i know have a jet? know of any? find a guy who has a jet and work for free if you have to. janitor closets are not all that bad and stairwells are seldom used.
