Hence my question.
I don't use lines that go through things, or lines in general, so I can't comment much.
I did do some research on pitchforks and learned a bit about it, it seems to work quite well.
Was curious about your discoveries. Test it, and post results, maybe you have something good, but you'd need to be very specific with the application to not be fooled by hindsight biases. Also, you'd need to define how to apply it to trade with it.
My 2 cents.
