That is not fundamental analysis because volume and reading orderbooks are part of technical analysis. Volume is a important indicator because it tell something where it can give a glimpse where there will a reversal or if there will be another momentum. There are many uses of volume, I usually use it if I will trade a coin especially if I will range trade it. Fundamental analysis is all about tips, news and rumors around the internet. the analysis that you should use depends on what is suitable for you.
A little bit scroll down to this thread would be good.
I already explained how i used the volume and order book itself, fundamental analysis is a speculate using a various data. From a stock perspective we got this information from the outcome and income financial from the company to make a conclusion analysis. But since fundamental analysis on crypto doesn't have this data then the data was taken by the news and other things.
On TA we have some tools for volume and order book, but i used a volume/order books from information exchange not from tools from TA went the accuray more good on tools TA than exchange information that's why i put this to my fundamental analysis method.
