No, but we just had a more than 20% drop 64900 -> 47500.
Everyone using more than 5x leverage near the highs is now liquidated (if they did not close the position early enough).
The daytraders usually use something like 5x-50x leverage.
And the liquidation already starts when you are using 85-90% of your avbailable margin (depending on the platform you trade).

So I don't need any metric to tell you that alot of daytraders got rekt hard. Even harder in altcoins... you just need simple math and a good understanding of how leveraged trading works.
