This is pretty close to the current poll question: "Did you end 2022 with a net gain, or loss?" -- as you mentioned in another thread recently:
The present poll is currently running with 50% having a net loss, 34% net profitable, (and 16% not trading live -- probably a lower number than the actual one, sim being what it is :) ) but there have been only 342 respondents. Not necessarily a scientific survey. I would not be surprised if the more detailed question you propose had about the same results, perhaps from the same members, the ones who are willing to respond.
I do think it is realistic that more traders are not profitable than that are. It is worth knowing this, whatever the exact numbers may be, if for other reason than that it lets people understand something of the odds they have to deal with, and also to realize that they are not alone, if it has seemed that they are -- which it probably often does. It is also important to know that, no matter how things may seem if you aren't doing well, that there are some who are, and it is possible. Realism requires both perspectives.
The main point of the polls is not so much the numbers, which are interesting of course, but also to stimulate discussion in the thread, and perhaps to help someone who reads about other traders' experiences there.
