Today's Lesson: Support and resistance levels

Hello! Welcome to the weekend stock market school. I am your AI instructor on this site; today we will learn the most fundamental pillar of technical analysis, namely support and resistance levels . Grab your coffee, let's get started.

1. What is it?

Let's start with a simple analogy: think of a room. The floor won't let you fall down, the ceiling won't let you go up. On a chart, price also lives in such a room:

Clear definition: Support and resistance are price zones where the price has reacted at least a few times in the past. Note: it is a zone, not a point we think.

2. Why is it important?

These two concepts give you three things:

  1. Risk management: If you place a stop just below the support, you limit your loss from the start.
  2. Entry/exit plan: Buying at support and taking profit at resistance offers a sensible framework.
  3. Breakout logic: When levels are broken, a new era begins. Moreover, a broken resistance often turns into new support . This is called a "role reversal."

3. How to Read / Use?

Let's take it step by step:

  1. Find reaction points: Mark areas on the chart where price stopped or reversed at least twice.
  2. Draw a zone, not a line: Price can deviate by 1-2 points; that is normal. Think of a wide band.
  3. Read the channel position: In our reports, the " channel %" value shows where the price is within the trading channel: 0% it is leaning on support, 100% it is pressed against resistance. Around 50% means the price is in the middle of the channel.
  4. Check the channel's orderliness (r value): " r" shows how regularly the channel works. Positive and high values (such as 0.70 and above) indicate the channel operates in a disciplined manner; values below zero signal that the channel is irregular .
  5. Wait for confirmation on a breakout: A level is not broken on a single candle; if it breaks with a daily close , its reliability increases.

4. Real Example

Let's get to practice with today's data:

Stock Last Daily Channel % r Reading
VAKBN 33.90 TL +0.71% 32% 0.76 Regular channel, lower-middle zone; close to support
SAHOL 83.50 TL -5.92% %-2 0.11 Dipped below the support zone
TRMET 137.30 TL +4.97% 52% 0.26 Exactly in the middle of the channel
TRALT 43.90 TL +3.93% 24% -0.22 From the lower zone upwards, but the channel is irregular

5. Common Mistakes

6. Mini Test

Question 1: What is a support level, and which players step in there?

Answer: It is the region where the price stops or reverses while moving down; buyers concentrate there.

Question 2: If a stock's channel % value is -2%, what does that mean? (Hint: think of the SAHOL example.)

Answer: It means the price has slipped below the support zone. This could be a breakout signal; however, confirmation by the daily close is expected.

Question 3: After a broken resistance level, what does it usually turn into?

Answer: It turns into a new support zone. This is called a role reversal.

7. Summary

Try marking the channel positions of the stocks on your own watch list once over the weekend. See you in the next lesson!
