Mr. Lindloff buys shares in Patterson-UTI Energy, because he thinks it looks ripe for an uptick. Instead, it dives a few cents, and because Mr. Lindloff has an automatic stop on the trade — which sells the shares if they dip below a certain threshold — they are sold for a loss. A moment later, the shares shoot up.

Mr. Lindloff thinks he has been juked and jived by a robo trader.
