Headway's line drawing tool is like a draftsman with a compass. The trend lines I draw automatically snap to highs and lows, making them much more accurate than my previous platform. Last time, when I was drawing a rising gold channel, it helped me pinpoint two key lows, and the market subsequently followed the channel. However, the tool can be a bit stubborn, making fine-tuning the lines difficult. I have to click and drag several times. A bit more flexibility would be much easier.
