$Tesla(TSLA.US) is still nerve-wracking to go long. There were two chances to break even and exit, but based on past experience, as soon as I sell, it takes off. I held back and wanted to wait, but it fell again, and I didn't do any day trading. Every time I sell too early, I only make a few dozen, but holding a bit longer could mean hundreds. The problem is, if I don't sell, it falls, and only after selling does it take off—it's really frustrating. (Missing out on gains is way more painful than being stuck in a losing position.)
