Which guide is missing from the learn page for your trading style?

The learn page groups the site's guides into beginner lessons, in an order meant to build one skill on the last. A guide in the wrong place is often one that assumes knowledge the reader has not yet built. Trying the order from the top is the quickest way to find that gap. The question for this thread is which guide you wish existed, or which one you think is in the wrong place.

The order may suit a complete beginner better than someone who already trades. Someone who already trades may want to reach the risk guides first, while a complete beginner may need the basics before any of them. Tell us which guide you missed, and where it would have helped you most in the order.

We would like to hear your view:

• Which guide is missing for your trading style, and what would it cover?
• Which guide would you move earlier in the learn order, and why?
• Did a guide help you avoid a mistake? Which one?
• What would make the learn page easier to start from if you already trade?

Please share your own view and reasoning. Posts that promise a direction or sell signals will be removed.
