AFAIK, Tradingview lists only those tokens/coins that are listed on the exchanges that they are tracking (e.g Binance, Bitfinex, Coinbase etc). As seen
in this article, 30 exchanges are supported by now and PancakeSwap is not yet among those. From what I can see, no DEX exchanges are supported yet, not even the most popular one, Uniswap.
Regarding the alternative, I can suggest you
Coingecko which I prefer over more popular CMC.
