I see you're omitting two swing high tails? Why is that?
There's many ways to draw such a line and that just illustrates the subjective nature of this stuff. Solution? Work out some definite rules for how to draw them.
I think this is how Victor Sperandeo suggested to do it for a down trend line:
1. Determine trend line starting point, i.e., start of trend.
2. Draw trend line between the starting point and the last minor high preceding the lowest low such that the trend line contains all prices.
So, even with this in place you need to determine what exactly is the start of the trend. My interpretation if I use the same starting point as you then would be this:
Using the same rules for the up trend line - it looks not quite correct.
Still, you're at a disadvantage as price may very well retrace back down to that blue trend at the bottom.
Maybe it's better to buy swing lows and sell swing highs instead?
Personally, I don't use trend lines. Only if they're very, very obvious.
