1 Day MACD with a color coded area style histogram, with a black line indicating the 4H histogram with + markers to indicate true 4H crosses.
The black line is the outline of the 4H histogram, with a floating cross above to confirm that it is above 0.
4H histogram settings = 6, 13, 5 MACD. Not a true 4H resolution, but extremely close. Effectively, the black line is actually a 2X speed MACD. I prefer it over a true 4H indication.
