bookTicker returns markets with price 0.00000000 - inactive?

542 out of 2005 symbols returned by /api/v3/ticker/bookTicker have all values (prices and quantities) of 0.00000000

I checked a few symbols on the website and they don’t seem to exist. Is the 0.00000000 value used to show the market is inactive? (Seems plausible, but I don’t want to assume.) Thanks.

Is the 0.00000000 value used to show the market is inactive?

This is correct. A symbol’s price is set to 0 when the symbol is no longer tradable on the Binance Exchange.
