1. What is Resistance?

Resistance is a predetermined level from where the prices stop rising.

It can also be referred to as a level on the chart where the traders expect maximum supply for the stock.

The logic behind this is that as the price advances towards resistance, sellers become more inclined to sell and buyers become less inclined to buy.

Whenever the prices touch the resistance level it begins to fall and if the prices break the resistance level then it continues to rise.

Resistance is one of the most important tools which the market participants analyse when the market is rising. It often acts as a trigger for selling.

As the process of identification of S&R is same, first let us discuss about support then we will discuss the procedure to identify both S&R .

2. What is Support?

Support is a predetermined level below which the price stop falling further down.

It is a level at which the traders expect maximum demand for the stock.

The logic dictates that as the price declines towards support and gets cheaper, buyers become more inclined to buy and sellers become less inclined to sell.

Whenever the prices touch the support level it bounces back and begins to rise and if the prices break the support level then it continues to fall down.

Support is one of the most important tool which the market participants analyse when the market is falling down. It often acts as a trigger for buying.

Now that we have understood the concept of S&R , let us understand the procedure for drawing S&R levels

3. How to draw Support & Resistance Level in a chart?

Let’s go through three really simple steps for drawing S&R levels.

Step 1: Selecting your timeframe

If you want to find S&R for a short time frame, then you should load price chart of at least 3-6 months. If you want to find S&R for a longer time frame, then you should load price chart of at least 12- 18 months.

The reason for selecting the above-mentioned timeframes is that:

The chart will get compressed and it will be easier for you to identify
(S&R) levels.

From the below charts we can see that 12 months’ price data chart looks more compressed than the 6 months’ price data chart

Step 2: Identify highs and lows

After loading the price charts according to your timeframe as mentioned in step 1, mark the areas of low and highs in the chart as shown below:

Step 3: Connecting the highs and lows

After identifying the highs and lows as mentioned in Step 2, join the highs with a line which will act as a resistance and similarly join the lows with a line which will act as a support as shown by the red lines below:

One should note that when drawing a support or resistance line, one should identify atleast 2-3 price zones from where the price has showed the below behaviors:

  • Not able to move further up or down

  • Reversals have occurred at that point

4. What is the difference between Support and Resistance?

If the price of an asset does not go below a level, then it is known as the support.

Whereas if the price of an asset does not go above a level and reverses from there then it is known as the resistance.

One should just remember support level as a floor and resistance level as the ceiling

5. Understanding S&R Reversal and how to use this concept?

One of the most interesting facts about S&R is that when the price is finally able to break the support or resistance, then it forms a new support or resistance level.

The previous resistance becomes the new support level whereas the previous support level becomes the new resistance level.

Example of Support becoming Resistance:

6. Practical Concept: Trading based on S&R levels

One also need to understand how does the prices move of a particular asset to interpret S&R from this framework.

One should know about the major and minor S&R levels.

Minor S&R can be broken whereas strong S&R may stop the prices to move in the ongoing direction and cause reversals.

7. Reliability of Support and Resistance

One should remember that the S&R lines only indicates possibility of reversal of prices.

This by no means should be taken for granted.

Like any other indicators of technical analysis, one should analyse the possibility of an event occurring based on the price patterns in terms of probability.

Thus one should keep the first rule of technical analysis in perspective which is: “History tends to repeat itself” and so will the S&R levels.

Key Takeaways

Here are the 5 important Rules of S&R which you should remember while analyzing the same:

  • Support and Resistance often act as decisive trend changers. When an existing trend line meets resistance, be prepared for a dynamic shift.

  • If support is violated, that same level will act as future resistance.

  • The more often a trend line is tested, the more valid it becomes.

  • If a resistance or support level is associated with increasing volume, the trend becomes more valid.

  • The more recently a level has been established, the more useful it is.
