The graph analysis for candlesticks is very important to understand. It shows the opening price and closing price in the solid green (gain) red (loss) bar. The high and lows are the lines protruding from the candlestick graph. The open is below the close if it is green (gain) and the open is above the close if it is red (loss).

This allows us to track the progression of the price of a cryptocurrency. Analyzing trends is a whole other beast which requires quite a bit of practice and studying.
