Maybe I should post another version which shows 'Has your bias (or no bias) made you money consistently over the last 3 year period?'
What is your definition of good return? if your job has flexible hours you don't need to quit your dayjob or evening job to make money trading.
And the 2nd half of 08 you are down all the gains you made + how much more. If you never sell you don't see any return on your paper portfolio
