Why does Tradingview say sell?

Here is a screenshot taken tonight. At 7100, I’m thinking

BUY!

My guess is it’s following the trend, and it’s on a downtrend.

Its telling you whats happening; the trend is at that instance there is a larger volume of BTC being sold than bought. Thats all… from a trader prospective its time to buy… buy whne other are fearful…
Kind regards,
