What is the trend line?
The trend line is a line that connects price highs or lows to show the prevailing direction of price on the chart. Trend lines are graphical representations of support and resistance and can be rising and falling.
In case of an increasing trend, the line will show the trade is in an uptrend and opposite.
How to draw a trend line?
To draw a trend line, we need to connect either highs or lows using a diagonal line. To draw an upper trendline, we need to connect successive price reaction lows. To draw a down trendline, we need to connect successive price reaction highs (peaks). The trendline importance depends on the number of lows and highs that are connected. For example, the upper trendline that connects 5 lows has greater significance (stronger support) than the trendline that connects 2 lows.
Valid trendlines need to connect at least 3 lows for the upper trendline or 3 high for the down trendline.

Trendline drawing tips
If you go for bigger frames such as monthly, daily, weekly, four-hour charts, you will find them the best line trends.
There are times you have to face situations such as the cylindrical sticks overlapping the trend lines. You can manage it by making the stick a bit low or high. However, you must avoid cutting the cylindrical lines from between.
You must not use force to adjust a trend line in the chart. If it isn’t the right fit, then you must leave it there.
You have to utilize points one and two to draw the trend lines, but there must be proper space between them. Traders will not accept lines that are nearby.
When you use the breakout process on the trend line, you have to hang there for the price to break on the line. The trend lines will guide you to choose the buying and selling chances, and sometimes you can even do business with the top and purchase at the bottom of the trend line. If you have larger frames, they will have more importance than the smaller ones.
