I recently had an old 401k error that resulted me getting an additional about 1k. Instead of rolling it into my main retirement accounts, I decided I would use it to start investing with a self directed account.
One observation that I've seen from the basic charts Merrill Edge provides is that volume of trading is closely correlated with the first derivative (rate of change) of the stock price.
Logically it makes sense that when a price is dropping (or going to drop) people want to sell, and vice versa. In what situations would this to not be true? What kind of information, or variables, should I be looking for to determine when this wouldn't happen?
