Stop Losses: A Trader's Best Defense

24 พ.ค. 2023

In a perfect world, every trade would go our way, but alas this is usually not the case. A stop loss is a risk management tool used by traders and investors to minimize their losses when trading. It is a predetermined price level at which a trader's position will automatically exit the market, causing the loss to be realized. Stop losses are crucial to any trading strategy, as they help traders limit their losses and stay disciplined. In this blog, we will look at what stop losses are, why they are important, how to set realistic stop losses, and five different examples of stop losses with a description of how to set the stop loss.

What are Stop Losses?

A stop loss is an order to sell a security when it reaches a particular price. It is a predetermined price level at which a trader's position will automatically exit the market, causing the loss to be realized. This means that if the price of the security falls to the stop loss level, the trader's position is automatically closed, and any losses incurred are limited to that level. Stop losses are essential because they help traders limit their losses and stay disciplined.

Why are Stop Losses Important?

Stop losses are important because they help traders limit their losses and stay disciplined. In trading, it is easy to become emotional and let your losses run. Stop losses help traders avoid this situation by automatically exiting the market when the price reaches a predetermined level. This ensures that losses are limited, and traders can move on to the next trade without being emotionally affected by the previous loss.



Setting Realistic Stop Losses

Setting realistic stop losses is crucial to any trading strategy. A trader needs to consider the volatility of the security, the trading style, and the risk-reward ratio when setting stop losses. The stop loss should be set at a level where the loss is acceptable but not too close to the current price level, as this may result in the stop loss being triggered prematurely. A stop loss should also not be set too far away from the current price level, as this may result in the trader losing more than they are willing to risk.



Stop Loss Examples

Below we will list five examples of setting effective stop losses. For consistency, we are going to use the same long stop loss example, but these same examples can be set for stop losses for short positions as well.

Percentage-Based Stop Loss: A percentage-based stop loss is a stop loss that is set at a specific percentage below the purchase price. For example, if a trader wants to place a long at $0.088602 and sets a 0.5% stop loss, the stop loss would be triggered at $0.88160. For a short stop loss at 0.5%, you would add the value instead and have a 0.89035 stop loss. To set a percentage-based stop loss, the trader needs to determine the percentage they are willing to risk and place the stop loss order at that level.



ATR-Based Stop Loss: An ATR-based stop loss is a stop loss that is set based on the average true range of the security. The average true range is a measure of volatility and is calculated by taking the average of the high and low prices for a particular period. To set an ATR-based stop loss, the trader needs to determine the number of ATRs they are willing to risk and place the stop loss order at that level. For a long stop loss, you would subtract the ATR times its multiplier from the current price. For a short-stop loss, you would add the ATR times its multiplier to the current price. The unique upside to this stop-loss style is the ATR accounts for market volatility which can aid your risk management and help set more appropriate stop losses.



Using Moving Averages or Super Trend: Moving averages and super trend are technical indicators that can be used to set stop losses. Moving averages are calculated by taking the average price over a specific period, while the super trend is a trend-following indicator that uses the average true range to calculate the stop loss level. To set a stop loss using moving averages or super trend, the trader needs to identify the period and place the stop loss order at the appropriate level. The Moving Average or Supertrend can then act as a moving stop loss as it trails the price.

2. SuperTrend:



Donchian Channels: Donchian channels are a technical indicator that can be used to set stop losses. Donchian channels are created by taking the highest high and lowest low over a specific period and plotting them on a chart. To set a stop loss using Donchian channels, the trader needs to identify the period and place the stop loss order at the appropriate level. In the example below we use a more standard 20-period Donchian level to identify areas of lowest low interest that would be a good place for a stop loss. If we were setting a short order we would look to recent highest highs as potential stop-loss areas



Conclusion

Stop losses are crucial to any trading strategy, as they help traders limit their losses and stay disciplined. When setting stop losses, traders need to consider the volatility of the security, the trading style, and the risk-reward ratio. Stop losses can be set using many different techniques, including percentage-based, ATR-based, using moving averages or super trend, and Donchian channels. By setting realistic stop losses, traders can minimize their losses and stay disciplined, which is essential for long-term success in trading.
