After trying to use a demonstration, you should be able to practice directly in the market. I agree with your advice. Because when we are in exchange, we will feel a different sensation in trading, because this is real not a demonstration anymore. And we can always practice to have good skills, because analysis and strategy are needed in trading such as advice from many people.
It is not a must to try directly into the market. We should ensure that we already have enough knowledge before we try the real trading. But if we feel confident with our knowledge, we can start the real trading in the market. It is true that using a demo trading is very different with real trading. Even if we may use the analysis both in demo and real trading, but the risks are different. In the real trading, we may lose the money if we aren't careful with our trading strategies.
It's all about trying directly or not. It depends on the readiness of each individual, because everyone will definitely be different in responding to the readiness that will be carried out, and it is impossible for it to be the same.
If you feel that you already have the knowledge to trade, of course you can try it directly, but what is expected is that you are not wrong in anticipating trading, so you are accustomed to doing it with the trading method with the smallest value first, so that when you are ready, there is nothing wrong with increasing it.
