What rationale are you using to think that someone might have to sell for a lose at some point in their trading career? ECDC is moving between 1's and 2's now; whereas, last month it was moving between 1's and 3's.
If people bought into ECDC in the 3's and wanted out now before it drops further, they would have to sell in the 2's. That's called a loss. They didn't buy with the intent of selling at a loss it is just the way it happened. Failure to understand such a simple concept as this is just ridiculous, as is, the condescending attitude used in a question that most non-traders could answer.
Consider yourself enlightened.
