I have shared the indicator in XARD thread as well... I am sharing it here again for anyone interested.... Instead of drawing ZZ/semafor dots, arrows, diamonds, or whatever you choose to call them - it draws a straight line which becomes kind of support/resistance line for future price action.... The indicator is very flexible in the choice of timeframes, length of lines and color combinations..... Good stuff. Salute to the unknown warrior/coder who coded it....

In the 2nd screenshot I have extended the lines manually for a clear view on how these lines act as S&R, and how these flip from one into the other..... Helps you form a clear picture of price movement and let you establish patterns that can be traded with the right kind of confirmation.... See the pin bar/hammer forming on one line that flipped form being Resistance to support.... Could be traded - Nah?
