Strategy 7: Support or Resistance Trading
Many traders love to draw diagonal trend lines. I’m not one of them. As far as I am concerned, they’re the exact opposite of objective. There’s a very good chance that two traders looking at the same chart will draw trend lines with very different slopes. A person in a mood to buy will be apt to draw a trend line in a way that shows a steep upward movement. On the other hand, if a person feels like shorting, they’ll be apt to draw a downward trend line.
The market only remembers price levels, which is why horizontal support or resistance lines on previous price levels make sense, but diagonal trend lines don’t. Accordingly, horizontal support or resistance trading is my favorite style of trading.
Support
is a price level where buying is strong enough to interrupt or reverse a downtrend. When a downtrend hits a support level, it bounces. Support is represented on a chart by a horizontal line connecting two or more bottoms (see Figure 7.26 below).
Resistance
is a price level where selling is strong enough to interrupt or reverse an uptrend. Resistance is represented on a chart by a horizontal line connecting two or more tops (as also set out in Figure 7.26 below).
Minor support or resistance causes trends to pause, while major support or resistance causes them to reverse.
Traders buy at support and sell at resistance, making their effectiveness a self-fulfilling prophecy.
Using this method, every morning I shortlist the stocks that I would like to trade based on the criteria I set forth in Chapter 4. As potential stocks hit my scanner, I look for significant news events that may explain their price swings, such as an extreme earnings report or a new drug approval. You’ll recall that these are called fundamental catalysts and the shortlisted stocks are what we call Stocks in Play. They’re the ones that I’ll be monitoring carefully and planning to trade.
With these Stocks in Play identified, and before the market opens, I go back to their daily charts and find price levels that have been shown in the past to be critical. Finding price support or resistance levels is tricky and requires trading experience.
For example, let’s take a look at Figure 7.26, an SCTY daily chart without support or resistance lines and another including the lines.

Support or resistance lines on daily charts are not always easy to find, and at times you will not be able to draw anything clear. If I cannot see anything clear, I don’t have to draw anything. There is a good chance that other traders who have shortlisted the same stock will also not see those lines clearly and therefore there is no point in forcing myself to draw support or resistance lines. In that case, I will plan my trades based on VWAP or Moving Averages or other chart patterns that I earlier discussed.
Here are some hints for drawing support or resistance lines on daily charts:
- You will usually see indecision candles in the area of support or resistance because that is where buyers and sellers are closely fighting each other.
- Half-dollars and whole dollars usually act as a support or resistance level, especially in lower than $10 stocks. If you don’t find a support or resistance line around these numbers on daily charts, remember that in day trading these numbers can act as an invisible support or resistance line.
- You should always look at the recent data to draw lines.
- The more of a line that is touching extreme price lines, the more that the line is a better support or resistance and has more value. Give that line more emphasis
.
- Only the support or resistance lines in the current price range are important. If the price of the stock is currently $20, there is no point in finding support or resistance lines in the region when it was $40. It is unlikely that the stock will move and reach that area. Find only the support or resistance area that is close to your day trading range.
- Support or resistance lines are actually an “area” and not exact numbers. For example, when you find an area around $19.69 as a support line, you must expect price action movement around that number but not at exactly $19.69. Depending on the price of the stock, an area of 5 to 10 cents is safe to assume. In the example with a support line of $19.69, the real support area might perhaps range from $19.62 to $19.72.
- The price must have a clear bounce from that level. If you are not certain if the price has bounced in that level, then it is probably not a support or resistance level. Important support or resistance levels on daily charts stand out. They shout at you: “grab me by the face
”.
- For day trading, it is better to draw support or resistance lines across the extreme prices or wicks on daily levels rather than across areas where the bulk of the bars stopped. This is the complete opposite of swing trading.
For swing trading, you need to draw support or resistance lines across the edges of congested areas where the bulk of the bars stopped rather than across the extreme prices. This is because the close price is more important for swing trading than the extreme wicks in daily bars are. The close price of a stock on a daily chart is the price that the market makers and professional traders have agreed on. Previous extreme high and low wicks have been made by day traders, so you should look at those.
Placing support or resistance lines, although difficult when you are first learning how to trade, is actually quite simple once you get the hang of it. For the sake of keeping this book more understandable for the novice trader, I deliberately limited my commentary on how to locate important support and resistance levels. You will find considerably more detailed information and criteria in my other book, Advanced Techniques in Day Trading

Let’s review a trade that I took based on these lines. Please see Figures 7.27 to 7.29 below. On June 21, 2016, CarMax Inc. (ticker: KMX), the United States’ largest used-car retailer, had extreme earnings and its stock gapped down over 3%. That was a perfect opportunity for retail traders like us to find a good trade plan. I quickly found the support or resistance area levels on a daily chart and watched the price action around those levels.

Figure 7.28 - KMX support or resistance lines on a daily chart up to June 20, 2016
.
After reviewing the daily charts up to June 20, 2016, I found four levels of $47.93, $48.42, $48.67, and $49.15. As you can see in Figure 7.28 above, all of these levels are extreme price levels for the previous days and, as I explained, I give more attention to wicks and extreme prices than I do to the open or close prices.
Now, let’s take a look at Figure 7.29, which is the next day intraday chart for June 21, 2016, and see what happened to the price action at those levels. I marked the areas where they acted as support or resistance. Do ensure that you give special attention to the volume of shares traded at or near those levels. Do you see that the volume is considerably higher? A high volume confirms that these levels are significant and day traders should therefore pay attention to them.

.
When the market opened, I watched the stock and realized that the area of around $48.67 was acting as a resistance level. Later, the stock sold off to $47.93 with high volume. I bought 1,000 shares at that support, with a stop loss below $47.93. If the price closed below that, I would be out with a loss, but it didn’t. The price instead quickly bounced back. I sold 500 shares at $48.42. I sold the other 500 shares at the next resistance level of $48.67. I kept monitoring the price action and, in the afternoon, when the price rejected the $49.15 level with high volume, I went short with a stop loss of a new high of the day or a close above $49.15. I covered half of my shares at the level of $48.67 and the other half at $48.42, both for another nice profit.
To summarize my trading strategy for support or resistance trading:
- Each morning, after I make my watchlist for the day, I quickly look at the daily charts for that watchlist and find the areas of support or resistance.
- I monitor the price action around those areas on a 5-minute chart. If an indecision candle forms around one of those areas, that is the confirmation of that level and I enter the trade. I usually buy as close as possible to the support level to minimize my risk. Stop will be a break and a close of a 5-minute candlestick under the support level.
- I will take profit near the next support or resistance level
.
- I keep the trade open until I hit my profit target or I reach a new support or resistance level.
- I usually sell half-positions near the profit target or support or resistance level and move my stop up to my entry point for break-even.
- If there are no next obvious support or resistance levels, I will consider closing my trade at or near half-dollar or round-dollar levels.
A similar approach will also work when you sell short a stock below a resistance level.
