Thanks for sharing.
I like it better than a single line, coz we can adjust the width of it, which act as a range rather and a level.
What i mean is, how sup/resitance is not always a single level, but a small range, the width of tool defines the range.
Like how in YOUR lupin chart above, the support is a range from 920 to 924. and one needs two lines(not one) to cover the double bottoms
Same goes with the trendlines.The width help to cover lot more spikes and smooth out the pattern
