What are Support/Resistance Lines? (How to draw and read them?)

When you see a stock chart, there is hardly any chart which moves only in a linear fashion. Usually there will be ups and downs, hence it will be wise to find all this bounce points also known as support and resistance points. Lets see some examples of those lines and what do they mean to investors.

1. Support/Resistance Lines

Support lines comes in 2 main forms
– Uptrend support Line
– Downtrend support Line

Uptrend Support/Resistance Line
Support lines are the lower limit set for graphs. They normally provide guidance to indicate if am uptrend, downtrend or consolidation phase is still going on or not.
The green line is a weekly chart uptrend support line

From the screenshot above from investingnote.com, we can see the Green line which guides the upward trajectory of the company’s shares. This uptrend support line indicates the company’s growth and performance over time. This is only accurate insofar as there is stability in the business and the overall economy.


Resistance lines are the upper limit by which share prices hits and falls from. They normally provide guidance to indicate if am uptrend, downtrend or consolidation phase is still going on or not.
The orange line is a weekly chart uptrend resistance line

From the screenshot above from investingnote.com, we can see the orange line which guides the upward trajectory of the company’s shares. The uptrend resistance line “limits” the growth in terms of the share prices amidst volatility in the market. This line will be a good gauge of how high would the price rally towards.

2. Moving Averages

Moving Averages are basically lines drawn based on previous days or weeks share prices. This lines are weighted hence the latest share price should gravitate to the moving average unless there are major news or updates about the company or markets causing the large deviation.

Moving averages provides you with a best fit line which shows how the trend of the price movements are compared to previous trading days or weeks, as defined by the user of the instrument.
The Blue Line is a 20 days Moving Average

From the screenshot above from investingnote.com, we can see the daily candle sticks hovering around the 20 days moving average (Blue line). Using this instrument you will be able to observe how far is the share price from its moving average. Judging based on past share prices and MA, you can then compare them to have a better idea on when you should buy or sell a share.

I encourage young investors to play around with the charts on Investingnote.com to have first hand understanding of support and resistance lines.
