Many novice traders have misconceptions as regards how to draw trendlines. You need to pick a timeframe to draw trendlines that work for your strategy. As a beginner, you should pick a high timeframe as it gives you time to plan and reduces the emotions of the volatile market.
Look for swing points, either highs/lows of at least two points; if it is tough to get, zoom out or take a few distances from your screen to view them.
Haven found these points, draw your trend line, and do not force trendlines if they are not fitting in.
