Losing is part of successfully trading. If you treat losing as part of trading then you are an experienced trader.
Fear of losing money in trading is normal and greed for taking high profits is normal too, what we need for overcome them are focus on our system trading/trading plan/rules of trading that be made by our self before entry to markets, we must follow the rules of trading that give us profit consistently and the system trading. just for my opinion
We cannot avoid any losses as long as we take risk. It is part of it and we are the one who control it. We cannot move away our fear, it is always their to control us but we can overcome everything. Experience will make you stronger and teach you a lot of things to do so. There are no person that become successful because who do not do a mistake and never lose their money in trading or investing, they are just good in handling their lose and continue to make it grow again.
