If you are a more experienced trader, the advanced options allows you to view more detailed statistics. For example, if you were interested in the price movements between Bitcoin and Ethereum, there are more advanced graphs you can view. Candlestick bars allow you to view the opening, highest, lowest and closing price of a cryptocurrency over a specific time period.
Just remember, if you are just getting started with cryptocurrency trading, it is probably best that you use the basic option until you feel more comfortable!
