My Tradingview charts say QTUM $48 but coinmarketcap and everywhere else it's $61. Am I missing something? Same with Monero $365 on Tradingview charts vs $394 on coinmarketcap and other sites. LTC seems to be ok on the charts though.

Is it simply because of different exchanges? I know Korean exchanges are thousands higher than other exchanges for BTC for example but I'm just comparing TradingView and average exchanges.

Coinmarketcap is getting an average I guess but how does that affect your trading when the charts you use are not the same charts as the exchange?

I mean 99.99999% of the exchanges have crappy charts.
