People become aware of their mistakes only when their mistake was made. So it is unlikely they will be aware of possible damage before they make the mistake. People also make mistakes due to differences in the UI of different trading platforms. Sometimes people get confused with the terms the platforms use. For example, leverage trading and Future trading are technically the same thing. However new traders may get confused because different platforms use different terms.

Now, all I wish is that whenever people make some mistake, I wish they learn from small mistakes with minimal damage. People should not start trading with thousands of dollars. I remember not knowing about cross leverage which actually drains your spot funds as well.
