One of the reasons why traders loose money everyday in their trading is 'greed'.
beside greed,they also have no skill to put they order in market. by analizing chart and set money management such as stop loss or any thing else it could avoid us from lossing money .greed maybe happen for whom have profits in their trades but still expecting more till price fallen and profits become loss. having big position and didnt applied money management also be why reason why alot traders liquidate.
Greed remains in the first place that makes many traders lose money, making themselves aware not to be greedy when trading is something that all traders need, when it is successfully mastered, the trading knowledge and market analysis that has been done will definitely be effective. i can say that trading includes emotional management.
