Sure. Everything keys off of XAverage1. As it moves, touches or crosses any other XAverage, the cells light. Green means it is above it, red below it and yellow for the same as it. Then, the +,-, and = signs tell you which way between each Xaverage the Xaverage1 is pointing.
Some say trade when a 4 EMA crosses an 8 EMA (or the 3 and 6 or whatever). This indicator is more sensitive than that on the first few EMAs and less sensitive on the later EMAs at default settings. It is up to you to decide how many greens or reds it takes for you to make a trade. One green? Three greens? Five? That is up to you. Also, just say you are in a long trade and all your lights are green. Price has a pullback, and the first 2 lights turn red. You know you should stay in the trade for more profit because you have previously decided that it takes at least four reds before you make a trade. You can use it to put you in a trade and to take you out. But you have to see it live and decide what your tolerance/risk levels are.
Probably best to watch the the same interval chart and Radar at first to see how it behaves. Then make a decision of what works best for you.
And by the way, I started writing this indicator this past Friday afternoon and only had 3 plots at that time. It was after the close of the day, last night, when I decided to add 3 more so I haven't even seen this in action yet, in all it's glory! However, I do feel confident that it will work as intended.
My idea is to use it as a "strength meter". With only 3 plots it was working and looked great. With 6 or 12 it should rock. I tested it on multiple symbols, time frames and looked at magnified charts to make sure it was working properly. If you notice any oddities, let me know and we can adjust it.
One thing I did notice is that when price is flat, you may get all of one color depending on which way price is slightly trending. So you do still need to look at the chart. At those times, note that price is flat and then when price makes a break one way or the other, you'll know what to do. It appears to work best at up and down times. Keep that in the back of your mind.
