if you are expert or skillful then you can be a good and successful trader and i am very skillful trader and earning a huge profit from trading and sometime i think that trading is depend on your luck.
i agree with you that if someone skillful and expert in trading and have a good knowledge about trading then surely who is a successful trader and these trader will be never face to lost in trading and they get a big profit from trading.
You are completely wrong every trader will loose some money because trading is not completely depend by one person, there many people who are trading for their benefits,you have to plan according to that and you have to take right decision at that point in order to make profits.
Every time it is not possible to make profits because many traders have lot of plans to implement you need to prepare for every thing and try to concentrate you trading what ever the skills you have in order to make profits.
but i think for every tine you must have your own strategy for every time you need to have good knowledge about the market, and for every time you need to put risk to make good money.
