New ETF Holdings Functionality

I spend an inordinate amount of time updating & cleaning up data that comes into SwingTradeBot. A good portion of that is removing acquired & delisted stocks and filling in missing data for newly listed stocks & ETFs. So I see a ton of ETFs being added to the market every month.

They explained how shorting worked and actually took a small sum of money and shorted the S&P 500. But they left out some things that I think are very important to fully explaining the risks of shorting.
