according to one study, most traders lose because they kept trading after they have met their target. (either daily target, mental target, or percentage target, etc.)Quote from forex-forex:
The Hillary trades were odd. I read that she turned $1000 into $100,000 in less than 1 year. She had no losing trades and suddenly stopped trading when she reached $100,000, no explanation why she would stop trading after such a good run.
