Choosing support and resistance can be time consuming and subjective. Personally, I don't want to spend too much time manually marking up charts. Credit to video I saw, forget the producer, that demonstrated how multi-time frame Bollinger Bands can act as support and resistance. I suggest reading up on Bollinger Bands (en.wikipedia.org/wiki/Bollinger Bands) and how to use them in your trading. This indicator draws support and resistance lines based on Bollinger Bands on three time frames. You can select 1 or all three time frames to display on your chart. Enjoy.
Updated...Added option to set S&R line colors by time frame.
