I loved this game. As soon as I saw the title I knew it would be Wall Street Raider. I play it via dosbox and for me the UI is part of the charm. I’d be interested in tinkering with the pricing simulation but from the article it seems like that’s almost impossible.
Not impossible but a lot of work. But with Custom Data API and Set Game State API you can do a lot of what you may wish you could do from modding the frontend. Not ideal but it goes from impossible to a possible!
