I've been watching Flare for quite some time plotting a potential entry for a long-term hold. (See my previous posts on Flare.)
This chart shows that each time the histogram on the MACD is green, once the green bar turns white it signals a downturn in the price (as indicated by the red arrows), and those signals thus far have acted as a barrier that present significant resistance to future price movements above those areas (represented by the red lines).
