One handle, several portfolios

I’ve added a few changes to Wall Street Game) to make it easier to test different investment ideas with virtual money.

You can now create and name several portfolios under the same handle: Oil, AI, or whatever you want to explore. Each handle still starts with $100 million in total, which you can divide between portfolios by moving available cash. Your existing portfolio keeps its holdings and recorded history, and stays named after your handle until you rename it.

In addition I have added another leaderboard. The old one ranks handles by the combined value of their portfolios; the other ranks individual portfolios by profit or loss in dollars, with allocated capital shown alongside.

Click a name or total value to see the performance curve, the change over the last seven days where history is available, and every current holding. You can also open a handle and look through its individual portfolios.

A portfolio might still be $8 million ahead after losing $2 million in the last week. The curve makes that direction visible, so we can follow how an idea develops over time.
