There are people who have learnt how to trade, practiced on demo accounts for long but have not had the money to try trading on the market, and so they have abandoned trading to try search for money first. While there are others who have too little income, that they cannot profit from the market trading, they are always worried about loosing and because of that they make mistakes with their technical analysis and end up loosing the little money they have. Should trading be exclusive to financially comfortable and rich because of how risky it is?
Free trading is carried out by anyone who has the ability and is not limited only to the financially rich. Trading can be done by anyone, but without money, how can anyone trade? That's why trading requires capital because there are many risks involved, especially if you don't have any knowledge about trading. Many people have money but do not have the ability to trade because they do not have the knowledge and that is why trading is not only limited to people who have money.
Trading requires knowledge and money to be involved in it, without both we cannot do it. Logically, trading always looks at how someone can make a profit, but if people don't have the knowledge, we will actually be faced with the problem of losses. When someone wants to get involved in trading then one must have some knowledge and money without that never get involved in it.
