I think it's pretty easy: there are NO WHALE MOVES on the market, so there's nothing to identify. Some price fluctuations are natural, others happen due to bad/good news, FOMO, FUD, and other similar things. Usually when something writes about a whale move is then turns out that an exchange decided to move their funds or something like that. There's nobody able to make a significant difference, and if some rich people can make these tiny changes, should we really bother looking into that? And in any case, it's not like we can do anything with such people or we should act differently when we are trading and the price changes because of a whale rather than because of bad news, right?
