>>13154654Xylo...>>13155244You are right. It's mathematically incorrect since you should compare the closing price (taking it as 100%) to the current price (as a Current/Closing Price ratio times 100%), subtracting the former from the latter.
So, say, a 50% drop should mean that the price dropped by 50%, so by half.
There, a 50% drop means that yesterday's price was 150% of this day's 100%. It's mental.
Change it already, devs.
