You're right. It is not only time and it is not only bad experience. I have been trading since 1997 but I start to be consistently make profit last one year and I have friends who started to trading in high school, he is mid 40's now and he is still terrible trader. My brother is trading last 15 years and still he is losing money and every time he lost badly. His motto is 'all or nothing' so many bad experience.
You would ask; if you are good at trading and they are bad why you didn't help them? Answer of this question is also answer of your question. I did; I recommend to them books after they ignore me and still they were losing I bought the book (remittances of a stock operator) and send them as gift. My bother has never read it. My friend read it and ignore it. Recently my friend start to write to me on whatsapp. I put him such a situation that he can not ignore his mistakes but result wasn't became better on trading, result was escape from me. We were close to break 30 years friendship. I understand that, for him it is not about trading it was another something. As Ed Seykota said 'everybody find what they are looking in market'
So what it makes you experienced trader in my opinion is being open mind, critical mind and self aware person. You have to be honest to yourself. You have to search for true not what is in your mind as true but real true. You have to have passion not addiction of gambling. If your character is not improve itselves that way you would always be like a child in front of markets. This is nothing to do with time. What about bad experience, it is not about experience but how you deal with that experience. If you blame broker, your wife your children, your computer or birds on air than you will never get something from that bad experience next time when it is repeat.
It takes a lot of hard work to gain experience in trading. Forex trading is not an easy thing to do as you come into the market and make a profit easily. First, you need to get an idea about the price movement through demo trading. You need to gain a lot of knowledge from YouTube, Google, and various brokers while doing demo trading. You can learn any experience from a complete mentor. And you also have to learn from your mistakes.
EXPERIENCE CAN BE GOOD OR BAD AND IT ALWAYS COMES WITH TIME AND PRACTICE,BUT IT CAN ALSO BE GOOD OR BAD OR NONE BECAUSE I BELIEVE THE EXPERIENCE WE ARE TALKING ABOUT IN FOREX WHICH IS THE ONE WE WANT IT COMES WITH A FACTOR OF TIME ,PROGRESS AND A CONSISTENT APPROACH OF DOING THE SAME THING AGAIN AND AGAIN LEARNING FROM MISTAKES AND CORRECTING THEM AND GETTING BETTER HENCE MORE EXPERIENCED. IT CAN BE BAD IF YOU ARE STUBBORN AND FAIL TO LEARN FROM MISTAKES AND DOING THE WRONG THINGS OVER AND OVER AGAIN ,OR IT CAN BE NONE.
Good question ... Sorry to write directly without reading all the pages. My answer could be already written here ...
My personal history for gaining experience is like this ... 'Never ask a question about forex before you did big search to find the answer'. This means, you will work harder, learn more things while searching for answers. In case, you can't find the answer you are looking for, you may ask for it. The reason for doing this is to gain more knowledge and also to make the answer stick in your memory because you spent more time to get it. Easy come is easy to go.
If you follow this rule, sure, by time you will have more experience by time.
As a beginner, the best way to get some experience of trading is by opening a demo account. Once you have learnt how to use trading platforms and have a clear picture of what your broker offers, you can go live but use a small amount, because you are yet to discover how the live forex market looks. This is the best way to build your experience in the forex market and learn step by step.
