Use the button in the top left corner to open the menu.
You can draw on charts. Left mouse click to stroke with the cursor. Two right mouse clicks to draw a straight line from point A to point B. The scroll (middle) button click to insert an arrow.
Drawings disappearing when scrolling is intentional behavior. Make a screenshot of the page to save them.
Drawing is disabled on mobile devices.
You can scroll through the symbols using left/right arrow buttons.
Marked charts, color mode, and last selected chart will persist over page close.
You can create a link to a specific chart like this: https://dominikduda.github.io/#MSFT.US
The page will automatically refresh every 10 minutes. You can keep the tab open, and the charts will always be up to date.
All charts come from stooq.com
You can generate such a static page for yourself. Check out the readme of the following repository: https://github.com/dominikduda/dominikduda.github.io Note that stuff persisting over browser close won't work on localhost.
