There are lots of apps for that. Search for “demo account” or something. The ones with a real stockbroker are going to be the most realistic, and will probably use real market data delayed by 15 minutes. My favorite trading application so far is the desktop version of thinkorswim (TD Ameritrade owns it at the moment, but Schwab might be buying them.) It’s scriptable and has some nice analysis tools.
