RE:I'm getting old I know but what is an algorithm machinealgorithmic trading is just software written to execute trades in fractions of a second according to set variables such as price or volume of shares sold. I don't think it accounts for what's going on with VET myself, but maybe it does. Who knows?
stop loss orders, margin calls, and plain fear are more likely causes of the price dips on most days. short squeezes and greed drive it up just as fast.
