I have written some axioms that are widespread in trading platforms Which relates about currencies exactly:
1. Volume is really high, but price is still low?
the whales are accumulate the coin
2. Volume is high and the price is high?
the buyers are too much and the coin is top gaining
3. Volume is low and price is high?
a pump is happening here
4. Volume is low and the price is low?
this coin is dead , dont buy it .
simple but i hope i helped ,good luck
I did some space fixtures as it's confusing while reading those answers with the questions you have for example.
I appreciate the help that you're doing. #4 if the there's no actual volume anymore and it's not a lot, the coin is about to be dead but there is a possibility that some groups will pump it or any individual.
