If you go to study trading rules, greed and fear are mentioned as two most common enemies of a trader. When there is a null market and a trader is running into 100% profit he does not sell there and does not even lock his profit rather he goes for searching of next target as he wants to make it 500% greed does not stop him there even it touches 500% and one day it drops like anything and trader keeps on waiting for this recovery but unfortunately it does not happen and in fear of losing all his amount he closes the trade in loss. This is the story of most of the traders. Trade should be taken with a proper plan so that no factor like greed, fear or emotions effect it.
