A stop loss is actually a remote instruction to the broker, telling them at what price the trader wants to close the position, even if the trader is not in the room.
In reality, a stop loss is an order that remains in effect even if you do not touch your computer or smartphone through an app after opening it. You could, for example, open a position in the morning before work or in the evening before bed, specify a rate that will trigger your stop-loss, and start trading. A trade will be closed at this level at the right time: of course, if the prediction does not come true and the price moves in the opposite direction.

A stop-loss order is a risk management tool used in financial trading to limit potential losses by automatically selling or buying an asset once it reaches a predetermined price. This mechanism is designed to protect investors from significant downturns in the market.

For long positions, a stop-loss order is set below the current market price, triggering a sell order if the asset's value falls to or below the specified level. Conversely, for short positions, the stop-loss order is placed above the current market price, initiating a buy order if the asset's value rises to or surpasses the predetermined threshold.

The primary purpose of a stop-loss order is to prevent emotional decision-making during volatile market conditions. By establishing a predetermined exit point, traders can mitigate the impact of adverse price movements and limit potential losses. This risk management strategy is particularly crucial in highly volatile markets, where prices can fluctuate rapidly.

It's important to note that while stop-loss orders provide a level of protection, they are not foolproof. During extreme market conditions or gaps in trading, the execution of a stop-loss order may occur at a different price than anticipated. Traders should carefully consider market dynamics and set stop-loss levels based on their risk tolerance and overall trading strategy.
