If 5% of traders are successful, meaning they report trading as the majority of their income, why would you even bother?
5% means 5 out of 100 and its only the majority not all of their income. Meaning they can make 20k a year from trading and 10k a year from something else. That would be eligible for part of that 5% but is that what you expect, if! You are successful?
If you are part of that 5% is that what you envision? Also how many hours do you work, technically? If you are successful, meaning you are in that 5%, and you work 80 hours a week would you be happy with, 20, 30,40 or 50 thousand a year?
Your gatekeeping is a bit arbitrary. Success is whatever one calls it. If just "beating the market" is success, if simply outperforming the major indices is success, then I will hazard to say that there are a lot more than 5% of traders in the "successful" category. If successful means they can quit their "day job", then I think the statistics are probably still a bit higher than 5%, if you only count those who set out to be full time traders. And are you talking about swing traders, or day traders, or both?
And it is okay to TRY to do something with a low expectation of success. I buy my powerball ticket twice a week without fail. Yeah it is a bad bet. The actual payout is way less than the odds would have it in a fair game. I play anyway, for the dream. One thing is certain: You can't win if you don't play. Let me say that again. YOU CAN'T WIN IF YOU DON'T PLAY.
Not all rewards are strictly monetary. Myself, I get a great deal of enjoyment out of day trading. I enjoy testing my acumen against the thundering herd. I enjoy the interplay between risk and reward. I have often compared trading to Poker, and for me it is a similar rush, with less hassle. Plus I can see now that my trading will be profitable, and a welcome addition to my income, possibly making up the majority of it before long. As much fun as a hobby, but a money maker instead of a money consumer. I don't know that I could have ever become a successful full time professional poker player. I think perhaps my awe and respect for the real pros kept me thinking small, thinking I would not in the long run beat them. There is always somebody better than you. Kinda like being a gunfighter in the 1880s West, I suppose. Trading is less intimidating. The market appears faceless, at least at first. It is just a wall that can presumably be climbed or dismantled or undermined or flanked or a door found through which to pass.
My initial goal was to work with $10k and not lose it while I learned the ropes. In that, I was successful. In not "blowing up" my account, or even dipping very low before climbing back up to the initial amount, I can say that I was successful. Now that I will be playing with 5x my initial account, I believe that I will be able to trade 3 or 4 mornings a week and turn a profit, and see a bigger profit as time goes by and I develop myself as a trader. I consider that to be success. I beat the odds. I didn't fall into the 80% or whatever who fail or quit. I never thought I would fail and I didn't. Success. Got that, yeah. My goals were reached and my ongoing goals will also be reached.
If you only consider those who are determined to become full time traders, especially if you include swing traders, I would guess that the success rate by the standards of the subjects themselves is probably nearer to 50% than 5%. Most of the punters you run across in forums or chat rooms do not have that determination. They want it handed to them and don't see why they should make a vigorous effort to learn. That nearly all of them will fail is pretty much a foregone conclusion. This is an endeavor where a reasonably intelligent and disciplined person makes it on grit and determination. Those who won't make a genuine effort are food.
