From what can I see here. It is just showing that a trader doesn't have a goal or plan before entering a trade. I already experienced this like in the scenario I am catching a dump and longing it without planning at all.
In that case, you entered on a trade without stop loss or a price target for that trade, which is really bad practice for a trader.
