I can't find how to double investor account leverage

I’ve read I can double the leverage of my investor account in the “investor view” tab “chart” but I can’t find it there. May be there were changes and it’s not possible to do so?
Thanks in advance and congratulations for your platform.

The option is still available.
There is an article about it here:

If you don’t see the prompt, you may have already enabled it (the prompt disappears once activated)
It only applies to trades placed after activation, existing trades (if any) remain unleveraged.
