It's obviously an answer that has a dozen ifs buts and maybes and could be anything from 1 to never, but I thought it would make an interesting 'finger in the air' poll for a quiet winter's day. I've given the choices in #markets rather than time for obvious reasons. The idea is to give some of the new guys a realistic timeframe of what it takes to join the 5-10% who eventually stop losing. Clearly 'stopping losing' and 'paying the bills' are very different.
If you have a timeframe in mind, I thing a reasonable full-time target would be about 20 a day, 120 a week, 500 a month. You could trade more per day but it's probably best not to encourage people to trade every race. Maybe 500 is a bit high especially at this time of year....but it's only meant to be a very rough guide.
I've thrown my hat in the ring at a min of 9 months, which I've estimated at about 4500+. I've also allowed 2 votes per person so you can represent a range.
