any time you can become a trader. but my suggestion, when you start the better the earlier you already have a basic trade and try with a small capital. so you will not lose much in the beginning, and small capital is very good for learning.
Yes. We need to start with a small capital that is not terrible to lose, but also to ensure that the funds remain. Before you start, you need to learn the most important principles of trade.
Actually, there are some platforms that allow you virtual trading, where you can test you knowledge and your skill in trading without spending any dime just so you can get your feet wet in the market, and I found this really helpful especially for those who have no skill in it, because it guides you through the basics of trading, and prevents you from doing bad decisions that otherwise will prove to be a costly lose in the real market.
i do not think that virtual trading can help you so much. you need to have real involvement in trading and only then you can get some good experience in trading. because in virtual trading you do not have any worry about losing your money and therefore you may not be giving proper attention toward t. but if you will invest even a little amount of money in trading then you will certainly show great interest there and will tray to invest your money in such places where you have more chances of making money. therefore it is too much important to take active part in trading, if you want to get some experience.
