Price Action Guide -Part 5: How To Draw A Trendline


Technical chartists always assume that stock prices prices trend.

To figure out support and resistance levels, chartists draw trendlines.

A trendline, therefore, is a sloping line (that you draw) which helps you identify levels of support or resistance.


how to analyze trendlines

a. If the price moves up and pierces the trendline, it is a bullish signal. In the figure above (RIL, 1-Day Candlesticks Chart, price adjusted for bonus), you can see that so long RIL’s price remained below the trendline, it moved in a range. But the minute it rose above the trendline (Ex Bonus 470, CB 940) it raced all the way to 533 XB (1066 CB).

Here is one more figure to chew on, a continuation of RIL’s trend. After hitting 533 XB, it fell to 409 XB, and then in October 2017, it broke out of the new trendline at around 430 XB. Then on there was no stopping it as it went on to more than double in the span of 2-3 months.

b. Here is the 1-day Candlestick  chart of PFC. So long the price was above the trendline, it remained in a range. However, once it pierced 121 and fell below the trendline, it went into a free fall. Today, it’s in the 80s, a 50% fall.

c. If the stock price does not violate the trendline support or resistance, it remains in a range/trend.

If prices remain above the upward sloping line it means the stock is in a bull trend and money is chasing the stock. But when it pierces below the trendline, it implies that either bulls are tired or bears have taken over or there’s some adverse development in the market or in the company.

If prices remain below the downward sloping line it means the stock is in a bear trend and supply exceeds demand. But when it crosses the trendline upwards, it implies that either bears are tired or bulls have taken over or there’s some very favorable development in the market or in the company.

VERY IMPORTANT: After the price breaks either side, up or down, do not jump into the stock. wait for one more confirmatory candle.

ALSO: Pay attention to the volumes. If the breakout is not supported by volumes, it can be a false positive. 


Trendlines tend to favor investors. Though some traders do use trendlines, the general rule is that trendlines favor short-long term investors.


Investors should ideally use a 1-Day or 1-Month candlestick chart to draw trendlines.

Traders typically use 15-minute-to-30-minute candlestick chart on days of extreme fluctuations. But it works best for investors.




You should join AT LEAST 2 candle wicks or candle bodies. My trendline touches about 5 candle wicks as you can see in the image above. This is the Tata Chemical chart. Once the stock price broke out of the trendline at 465, and was followed by a confirmatory candlestick, it flew all the way to 781.

It’s very similar to how you draw the downward sloping line.  In the example above (JaiPrakash Associates), you can see the price has violated the trendline at 23.90, and the violation accelerated the fall. However, you also will see that a bearish engulfing candle was formed on 8-8-17, when JPA was around 27.

The bearish engulfing candlestick is also a very potent sign of an impending fall.

  1. Drawing trend lines is one of the few easy techniques that really WORK. Prices respect a trend line, or break through it resulting in a massive move. Drawing good trend lines is the MOST REWARDING skill.

    The problem is, as you may have already experienced, too many false breakouts. You see trend lines everywhere, however not all trend lines should be considered. You have to distinguish between STRONG and WEAK trend lines.

    One good guideline is that a strong trend line should have AT LEAST THREE touching points. Trend lines with more than four touching points are MONSTER trend lines and you should be always prepared for the massive breakout!

    This sophisticated software automatically draws only the strongest trend lines and recognizes the most reliable chart patterns formed by trend lines…


    Chart patterns such as “Triangles, Flags and Wedges” are price formations that will provide you with consistent profits.

    Before the age of computing power, the professionals used to analyze every single chart to search for chart patterns. This kind of analysis was very time consuming, but it was worth it. Now it’s time to use powerful dedicated computers that will do the job for you:


    • Joining 3-4 wicks or bodies can give a delayed signal. However, if you want to enjoin 3-4 wicks/points then it would be best to work with a leading indicator such as DMI.

      Also, the site that you are trying to popularize does not have an About Us page. Please don’t spread links of sites belonging to anonymous people on my blog.

    • You’re trying to look for RSI breakouts/breakdowns from trendline? If so, you can do it on daily charts. Because sales start from day and later snoball into a month’s breakdown or breakout
