Still working on the zoom function but here’s a go-around until then: Most (or all) browsers have a zoom function. On Firefox, click the hamburger menu (3 stacked lines in upper-most RH corner of page just below the X close button) to access the settings. Then click “Customize” and then drag the zoom icons up to your toolbar for quick access. You access the zoom function on Chrome via a similar settings menu.

Using Firefox, click any chart on RSOTC.com to expand it (or leave it as is) and then right-click anywhere on the chart & select “view image” which will open it in a new window. From there, you can click the zoom + button to zoom the image & use the scroll bars below & to the right to move the expanded image sideways or up & down.

On Chrome, you can either click the image to expand (or not), right-click on the image & select “Open Image In New Tab” & then use the zoom feature on Chrome to enlarge the image. I’d image the process would be similar on Safari, IE, etc.

True, limited risk.
What I meant is : derivative of a derivative.

Quite the opposite. When I buy an option I know that the worst thing that can happen is that the value of the option goes to zero.
With futures my risk is practically unlimited.

options on future, youre a brave man.

No options on /PA either. :-(
