The short answer

On Analyze, choose Fib or Box. Click two points. The desk paints the levels.

Hide a layer when you want a cleaner read. The drawing is still there.

Fib

Click swing A, then swing B. Levels land at 0, 0.236, 0.382, 0.5, 0.618, 0.786, and 1.

Use it to check a pullback you already care about. Not as an engine input.

Rectangle

Click two corners. Asia range. A news spike. A level you want to remember while you scrub the day.

It is your mark. Not an order block from a card.

Hide without deleting

Each drawing kind can be toggled off. Undo and Clear still remove. Hide only stops the paint.

What this is not

These tools do not change the card or the run. They help you see history the way you already think about it.
