Support and Resistance are the Most Powerful Indicators in the Stock Market Trading

Updated: Aug 30, 2021

Support and Resistance are the key price levels in which major bulls or bears present and sometimes they fight with each other to give a decisive move in one direction.

What is Support?

Support is the price level at which demand is assumed strong enough to prevent a further fall in the price.

At this level, buyers are more inclined towards buying and sellers are less inclined towards selling.

Why do Support and Resistance Occur?

Prices have memory. In other words, people do remember the important levels of any instrument, which makes them important for their psychology and supply & demand in the market.

As the price rises from support levels, traders who took a long position already feeling happy and will think to add a position, in case the price comes back to support level.

The next category is traders who missed the previous trade and will be eagerly waiting to take their new position if the price shows a pulls back to the original support level.

The last category is traders who took a short position and will not be happy when the price is going up. They will be looking for a price point to exit their positions asap with less loss.

When the price gives a pulls back to the original level, their loss is less, so they will try to close their short positions. Hence, they will indirectly turn as buyers.

The combination of efforts from these 3 types of traders creates the buying force at the support level, which stops the fall in price and instead pushes it upwards. How far it will go in the north direction depends on the buying force created at the support level at that point in time.

However, it is not mandatory for the price to stop falling and trend in the upward direction whenever it reaches any support level, because it depends on many factors, including the importance of the particular support level, overall market sentiments, and level of buyers’ participation based on their perception of supply and demand.

Similar logic is also applicable to resistance, and when the price reaches any resistance levels.

Support and Resistance concepts also work well in intraday trading. Trading opportunities do exist in all the timeframes in the market. An intelligent trader has to wait and spot the right opportunities to make profits in the stock market.

Support Turning into Resistance

Another important point to note is that support can turn into resistance and vice versa.

Once the price breaks an important support level, the broken level can turn into resistance. The break of support signals that the forces of supply have overcome the forces of demand.

Therefore, if the price returns to this level, the chance of more supply is high, hence causing resistance.
