Combining my day trading activities with my business that had nothing to do with stocks should I do it?

I am an owner of a S Corp, my business is about real estate investing and residential rental properties. I want to take the income from the business and day trade with it, or should I create another LLC that is for trading only and not mix?

But wouldn't that be commingling funds anyways if I had the two separate and moved some funds from my real estate business into my trading LLC, then if I needed the money for whatever reason in my real estate business, I move the funds from trading back to my S corp?
