Understanding the meaning of setting stop-loss points: why should all investors set them?

In stock, cryptocurrency, or other asset trading, not setting a stop loss is often the direct cause of beginners incurring losses. Many investors watch helplessly as their positions turn from small losses into huge ones, only to realize too late—that a simple stop loss could have changed everything.

What is a stop loss? What exactly does the stop loss point mean?

Stop Loss (Stop Loss) is about stopping losses. Simply put, it means that when a position’s loss reaches a predetermined level, the system or trader actively closes the position to prevent further losses.

The stop loss point refers to the specific price level that triggers this closing action. Once the asset price falls to the stop loss point, the order will automatically execute (if a conditional stop loss is set), so the investor doesn’t need to monitor the market constantly.

Here’s an intuitive example: You buy a stock at $100, setting the stop loss at $95. If the stock price drops to $95, the system will automatically sell, locking in a loss within 5%, rather than allowing it to fall further.

Why is it necessary to set a stop loss point? Practical case explanation

Malicious cycle of loss mentality

The main reason many investors suffer huge losses is not due to misjudgment but because they lack discipline in executing stop losses. Consider the following scenario:

Using $10 million to buy Apple stock at $100. If no stop loss is set, a significant drop might look like this:

• Drop 10%: account remaining $9 million, investor thinks “It might rebound, hold on”
• Drop 30%: account remaining $7 million, starting to panic but still hopeful
• Drop 50%: account only $5 million, needing a 200% increase to break even

More brutally, most people break down psychologically after losses exceed 50%, admitting defeat at the worst moment, causing losses to escalate from 50% to 90%.

Key advantage: reduce losses, improve capital efficiency

Compared to holding on, if you execute a stop loss at a 10% loss (losing $1 million), the remaining $9 million needs only an 11% return to recover $1 million. This is far more realistic than waiting for a 200% increase.

The core value of a stop loss is: first, to limit the maximum loss per trade; second, to preserve sufficient capital for subsequent trading opportunities.

Four main methods to set a stop loss

Method 1: Percentage or amount setting

The simplest and most straightforward method—set a stop loss at a 10% loss or a $100 loss. This is friendly for beginners, with clear rules that are easy to execute.

Method 2: Using technical indicators to find support levels

Resistance and support levels: During a downtrend, prices often repeatedly encounter resistance at certain levels (unable to break through). When the price breaks below a support level, setting a stop loss just below this level can effectively catch reversal signals.

MACD indicator: When the short-term line crosses below the long-term line, forming a death cross, it indicates downward momentum. The stop loss can be set below this signal level.

Bollinger Bands (BOLL): When the price breaks below the middle band from the upper band, it often signals the end of an uptrend. Setting a stop loss here can help cut losses timely.

Relative Strength Index (RSI): When RSI drops below 30, the asset enters oversold territory. While this doesn’t necessarily mean an immediate rebound, combined with other signals, it can serve as a stop loss reference.

Method 3: Conditional stop loss

Set a predefined price condition; when the market reaches this level, the system automatically executes the close. Investors don’t need manual operation, fully relying on the platform mechanism, avoiding human delays or emotional interference.

Method 4: Trailing stop (moving stop loss)

This is a more advanced application—setting a stop loss that automatically moves up as the price rises, but stays put if the price falls. The advantage is maximizing upward trend capture while automatically exiting at turning points.

For example, if the trailing distance is 2 points, and the price rises from $100 to $105, the stop loss will automatically move up to $103 ($105 - 2), locking in some profits while leaving room for further upward movement.

Practical steps: How to set a stop loss on a trading platform

Most legitimate trading platforms offer stop loss functions. For common trading software, the basic steps are:

1. Open the trading interface, select the asset to trade
2. Fill in order details (buy/sell quantity, direction, etc.)
3. Click the “Stop Loss” button, input the stop loss price
4. Confirm and submit the order

For trailing stops, additionally set the “trailing distance” (e.g., 2 points, 5 points from current price). The platform will automatically adjust the stop loss based on this distance.

Combining stop loss and take profit strategies

Don’t forget, stop loss is often paired with take profit. Take profit means automatically closing the position when the price reaches a preset target to lock in profits. For example:

• Stop loss at $95 (5% loss)
• Take profit at $110 (10% profit)

This setup provides a clear risk-reward ratio, with a risk of 1% for a potential reward of 2%, fostering healthier trading.

Summary

A stop loss point is essentially your “escape hatch”—it defines the maximum loss you are willing to accept before exiting. No one can predict market movements with 100% certainty, but by setting a reasonable stop loss, you can ensure that one bad decision won’t wipe out your entire account.

Whether using simple percentage stops, technical indicator-based stops, or automated conditional and trailing stops, the key is discipline—set the rules and stick to them, avoiding emotional decision-making. For anyone serious about investing, mastering the correct use of stop loss points is not just a skill but a survival essential.
