I follow this thread for a while with interest. The roofs and floors concept is a bit strange for me, because it depends on the "screen size", although it is true that these structures are horizontal supports and resistances, so they can work well.
(I hope) soon I will get an MT4 currency-index offline chart generator from the creator of CurrencyActivity (and LaserForks (https://www.forexfactory.com/showthread.php?p=11232440#post11232440)!) indicator, I will try these currency charts if these give some advantage vs. pair charts in my trading. Currency chart + support/resistance can be interesting.
