How do you auto-sell resources?

Its currently only available in next version (beta 11).

Here's how you can access next version: http://offworldtradingcompany.gamepedia.com/Next_version

Otherwise just wait a couple of weeks till the game is released to access it.

Thanks, that's really helpful.

I believe there is a small bug with the Auto-Sell Hotkey option.  I changed mine manually, but it doesn't seem to work, the only thing that works is Ctrl+Shift+ click on the sell button for a specific resource, If I use my custom hotkey and click, nothing happens.

what Auto-Sell Hotkey?

popsursocks, I do not believe adjusting the combination of buttons + mouse to auto-sell is an option. The only option in the hotkeys section is the "toggle selected auto-sell" which is different from the ctrl+shift+click toggle and works for me just fine. Now, if you want to be able to change how ctrl, shift, alt + click work, that's something certainly worth leaving feedback about.

You might be referring to one of the "Selected" set of hotkeys. Those are basically there for the Steam Controller to hook onto. I wouldn't expect anyone to use them with the keyboard.
