Trend lines are drawn on charts to help predict the general direction of price.It also help to determine good entry and exit point.they also help to see the reversals.
yes, my dear, for me I personally do consider that trend line is a line illustrating the price of a specific thing or currency pair on the graph is called trend line and mostly used for the technical analysis because prices may also be indicated in digits, The main object of the graph is to analyze the market prices first and then make any order. It very best method.
