What should the Beginners category cover next?

This category grows by request. The threads so far cover mechanics, risk, brokers and habits — but there are gaps only beginners can see.

Reply with:

• the question you couldn't find a thread for
• a topic you think beginners need before the ones covered here
• which existing threads helped you most

One topic per reply, so members can vote with the up arrows. The Learn section and the thread list both get shaped by this.
