if you can't see blood
don't be a doctor.
if you can't see a temporary loss
don't be a trader!
minor corrections are part of a trade. that's the only way price moves. majority trades experience low blood pressure and abnormal pulse rate at the sight of an adverse price movement. those who are not sure of their trade and those who can't see temporary loss can't hang on.
(caution : don't lose more (blood) than is warranted)
