what is your opinion?
Yes, patience is one key to success when it comes to trading. Also depending on how you trade like If you are a daily trader you would likely spend most of your time in trading. Spending too much time in trading is good as long as you are learning from it. Analyzing the market will be an advantage if you spend time on it.
It is just depends on how you feel comfortable whether you do spend a long time or just for a while until you feel it is enough.
I personally don't like to spend too much time without enough rest to think more reasonable in trading , all i can get when do it is a feeling underpressure to get more profit .
