Hello everyone, I would like to ask you how to become a stable profit trader, what aspects should be learned from it, I have read some books, such as price behavior, but still at a loss in the real market 
even a professional trader will not always be able to make a profit in trading. maybe you can start accumulating the trades you make weekly or monthly. if you are a day trader, then you will find how you can profit today but lose on another day.the step that I think is quite important is how you will limit and determine the risk of loss that you can accept in each trade. like you try to minimize losses as much as possible.
so you may later be able to see whether you get consistent profits every period you specify or not.
It's need a lot of patience and continually studying how the market works, just like what you mentioned better to have that certain limit where you can minimize your loses, you need to continue finding the right patterns and better strategy that will going to fit your attitude towards this venue of investment.
You need to always be open with adjustments and changes which will allow you to compensate in each sessions that you place your investment.
