This is a tough business and most never make it. That is the sad reality.
most businesses are tough and mo.st do not make it:why?
because they give up too soon,or because of something forces them to give up too soon:like running out of capital, running out of time because too busy looking after job family etc.
those who succeed are not smarter but have just been more persistent:Einstein once said:"i am not smarter than others, i just stay with the problem longer" [trying to solve it,being more persistent].
that is my personal experience: persistence is the holy grail, i started ten years ago to learn to day trade and have just turned profitable.
if you lose 95% of your trades, then you are doing the reverse of what you should be doing.It has taken me 10 years to do just that.
you cannot sell the top or buy the bottom so putting tight stops is not being sensible.
do you think traders like Goldman Sachs
trade with stops:they never go all in and never get a margin call.
But it is also true that they understand the market and rarely buy the top and sell the bottom:most traders trade without trying to understand the market and think they can operate with risk reward and stops.
It took me ten years to understand the market and how to position myself and i only use wide or 'gigantic' stops just in case of any 'black swan ' event.
