I'm still not sure why I lost money on a sale that should have brought in a fair profit. How much is commission per sale? Again, I'm new here, so I'm not sure how best to be making noteworthy profits. How high should you let the profit on a particular moviestock get until you sell it? Also, when I've bought my stocks, I always just click BUY. I'm not sure what SHORT or COVER mean. And finally, should I not have bought shares in about 20 different films? Should I just have bought a huge amount of shares in only a few films? And should I even be buying stocks in films that aren't coming out for another year or two (such as Hugo Cabret)?
