That is right.
Trading statistics is discouraging actually, but still it doesn't deny the fact people cease joining this industry. I guess if we look at the statistics of yearly growth of new traders in the market, it grows year by year, but of course the numvber of those eliminated by the market increases too. Nobody treat trading seriously, a lot of guys fail during the very first steps, that is what I see discouraging.
For staying afloat it's enough to comply with those things you mentioned.
