Yes, you are right, it is impossible for someone who is trying to trade for the first time directly to apply their experience, because experience is something that is obtained when we have done it. Except maybe learning from other people's experiences, and in my opinion that's not enough, because what other people feel will be different when we experience it directly. We will really gain experience after we trade.
This is different from knowledge, we can learn it at the beginning or even long before we actually start trading. However, this knowledge is usually in the form of theory only, when we want to test our knowledge with direct practice, we can first use a demo account.
They might try it for the first time but believe me they won’t make any single thing out of the first experience trying to trade, Experience Matter A lot because without experience, you cannot trade. A lot of people usually have misplaced priority, you have your own experience and learning from other people’s experience is also not a bad idea. The truth is that we need to embrace learning, others peoples experience. Their to many things when it comes to trading. To avoid unnecessary drama the best thing is just to go for the knowledge, that when you will be able to know exactly what you are suppose to do, so that you don’t wonder aimlessly in the market. And for people that wants to go into trading they should give value to knowledge. And they won’t have too worry to much about losing money.
