In that article I was using poocoin.app. Sometimes you can just enter the name of the token, but sometimes you have to enter the token address. it uses Tradingview, but by entering the token address, you can use Tradingview's charting indicators for lesser known cryptos that cannot be found on TradingView.com. with poocoin, there is no limit to the number of indicators you can use, but unfortunately, I do not believe that it saves your settings if you were to bring up a new chart in the same tab. Thanks for reading!
