4 Stop Loss Approaches to Keep Your Capital Intact

Sharing is caring!

Exits are as important as entries. A stop loss can protect you from a potential collapse in the stock market. No one likes to be stopped out prematurely, missing a massive trend.

How do you know where to place your stop loss to catch the bulk of the trend? This question has been haunting me for a long time. This topic gave rise to my previous article.

If you are new to trading, you may identify with my struggles and thoughts as described in the screenshots below. The screenshots are the conversations between Jay and myself.

Should I place my SL to get a 1:1 risk to reward ratio? Should I place it farther to increase my win rate?

These are some captures of my struggle in 2017. I learnt that it is best to select a stop loss level that is based on price action and volatility.

The 4 approaches

1) Previous previous day’s low: If you were to go long on BSX tomorrow, then a good place to put your stop loss level is where the previous previous day low as shown by the red arrow.

2) Market structure: Looking at support and resistance zones, place your stop loss below those zones. Here, the immediate support zone of BSX is too near for my comfort level. I’d prefer to move the stop loss level down to just below the previous support zone (red zone).

3) 1 ATR (Average True Range) below recent low: ATR is an indicator that measures the volatility of prices. The default duration is 14 periods. Add 1 ATR to the latest support zone and place your stop loss there (red line).

4) Percentage change: At times, prices may pullback and pierce through the support zone. This will trigger your stop loss if you use Approach 1. To add salt to your wound, the price rebounds and takes off without you. To avoid this, I use the percentage change indicator to tell me where to place my stop loss.

My mistakes

I used to change my approach when it was not working for me, as you can see in my chat with Jay.

I used to set my stop loss level based on the previous previous day’s low. When I get stopped out, would switch to Approach 2.

This reduces the number of shares I purchase (position size). This means that I make less money when prices go my way. Frustrated, I revert back to Approach 1 and get stopped out easily again.

As an idealist, I took trades that had a reward to risk ratio of 1:1 or better, combining it with Approach 4. This approach also reduced my profit, given the small position size.

Keys to note

Now as I set my stops, I do not worry about making money, I ask myself, “am I okay with losing/risking this amount of money?” If the answer is yes, I go ahead with the trade.

Sometimes a risk to reward ratio of 2:1 is fine with me when it comes to buying stocks. I am comfortable with holding on to the stock until the market proves me wrong. The main idea is to be comfortable with your plan.


Remember that a stop loss is where you believe prices should not hit in a given market. If it does, take the loss and move on.

If it gets hit too often, review your trades and adjust/reflect.

I would recommend getting a mentor. Personally I review my trades with Jay every quarter/half a year.
