@Ibbraar, Yes i know, but i dont think that you can rely on that. Because the strength of a parabola can be very different. For a normal trendline you got a linear line to see as support. But a parabola can be seen in different ways with a different slope. Ofcourse a parabola is something that can get you a lot of money, but you cant really set your buy order on that line for example.
