I have an embarrassing question, Binance?! What does it mean for the market indicators for more than one currency to be similar and equal at the same time?

Does anyone have an explanation for this strange phenomenon or is there a hidden hand manipulating the market?

Are stock trends based on real data recorded by the movement of the seller and the buyer and the indicator drawn according to the principle of supply and demand?

And why is the market of each currency linked to the other!
