My two best returning trades I let go away from me by >30% before getting profitable.
There is a lot of truth in what the OP states.
In a volatile / ranging / mean reverting environment - you will get away with it - obviously you did
In a relentless trend move against one's position - you'll get your nuts cut of..., and a margin call to boot
Longs - near the end of 07 = decimated
Shorts - mid 09 = decimated
These 3 - volatile / ranging / mean reverting environment - mask piss poor trading skills
As OP has said more than once
get right
