Thats why profesional trader which living from trading. They dont wacth chart whole day. They only take 2-3 hours to analyze market and making decision at what price they want to enter market. And then they set the stop lost after calculating the risk factor. They wont use very big matgin. They have good risk management base on their money.
You wont last if you arent really good on that risk management thing because you do really need to sustain yourself and you cant be called a good trader or who do live because of trading if you arent really that good. Everything should be balanced from the time you spent on trading and the time you
do deal up with your daily living because making things unbalanced would really result into this kind of common scenario where you are compromising
both health and social aspect.Always consider if you do like to live long where everything should be organized and time management.
