since they do not have losing years, so 66% is equivalent to compounding. but each year they have to pay tax, etc. so no one can really compound. i read somewhere that one investor with 10k would have 5400k after 30 years.
a successful professional trader told me that stock and future observes support and resistance, while forex does not. so he only trades futures. do not have first-hand experience.
it looks like thinkorswim
when thinkorswim say "online stock", does it mean all US traded around 7000 stocks? does thinkorswim provide api to trade stock? 0-commission IB lite does not have api.
if thinkorswim charges free commission, i guess lots of pro traders will move there given ibpro does not give in. but it looks like thinkorswim offers 0 commission on etf only.
