A stop-loss point is the price at which a trader will sell a stock and take a loss on the trade. This often happens when a trade does not pan out the way a trader hoped. The points are designed to prevent the "it will come back" mentality and limit losses before they escalate. For example, if a stock breaks below a key support level, traders often sell as soon as possible.

On the other hand, a take-profit point is the price at which a trader will sell a stock and take a profit on the trade. This is when the additional upside is limited given the risks. For example, if a stock is approaching a key resistance level after a large move upward, traders may want to sell before a period of consolidation takes place.
