Gloria: I've been studying trading for a few years (getting round to doing it is my problem...), and I've met all types of people in it. A common one is the trading educator who teaches with great confidence but doesn't actually trade - walk away. Next is the Sure Thing Get Rich Quick System - same. Trouble is, how do you know which is which in advance? Then there are a lot of disembodied egos floating around in the tradernet who are full of strong opinions but strangely short on proof they can do it. I reckon most of us here (or on ny other trading forum) are either aspiring traders or modestly successful ones - surely the message to anyone spending time in this forum who has made billions would be 'have you really nothing better to do with your time'?
The people I know who have made a long term living from personal trading do so in a range of different ways, but there appear to be some common attributes. Humility in accepting they don't claim to know what's going to happen next, stoical calm in the face of losses, an unusual attitude to money as just numbers on a page, interest in the process rather than the outcome, and the ability to disregard what the rest of the world is saying are some I've noticed. Big ego and flashy lifestyle is uncommon from what I've seen, some are really pretty boring 'grey men' - it seems like trading is mostly glamorous in the movies.
In relation to a degree to get a job in trading, a friend of mine is an actuary (a job most accountants regard as terminally boring) who until recently worked in setting up trading algos for a well known merchant bank. He didn't have the stress of trading, but he got paid trading size bonuses. My impression is that economic or other theoretical systems played little part in setting up the algos - he sat next to an experienced trader for 6 months and asked him to explain what he did. He disliked his job for as long as I've known him, but I think he got stuck in it for 20+ years because of the money - so, is life long enough for that?
On the other hand, a few of the personal traders I know who make it work for them trade for lifestyle - they're keen amateur sportsmen, or hobbyists, or similar, and trading is just a way to pay for and make time for the rest of life (none of them sit at their desk 12 hours a day). Sounds good enough to me. However, what few trading coaches tell you is that few of these people started with a $1,000 account - most had enough to start trading at low % risk so they didn't blow their account when they first started out for real.
