For example, if the price of Bitcoin is at $30,000, and after a while, it moves lower to $27,000. Meaning it shed $3000. One could now say that Bitcoin dropped 10% of its price.
Does the explanation help enough?
nope the 10% is
the 5% is if the price is $28.5k it shows how much USD is sitting on buy orders from $27k to $28.5k waiting to be taken
the 5% is if the price is $28.5k it shows how much USD is requested on sell orders from $28.5k to $30k waiting to be given
EG that image shows there was about $45m sitting on buy offers above $27k
EG that image shows there was about $45m requested on sell offers below $30k
