Yours is a time-sharing chart of individual stocks. In the time-sharing of individual stocks, the yellow curve (your market chart is blue) indicates the average transaction price of the stock in real time, that is, the total turnover of the day divided by the total number of shares traded.

White curve: indicates the real-time trading price of the stock.

Red-green bar line: below the yellow-white curve, it is used to represent the turnover per minute.

In the time-sharing chart, the red bar represents the buying quantity and the green bar represents the selling quantity.

Volume-refers to the number of shares traded on that day. In general, stocks with large turnover and rising prices are often better. When the trading volume continues to be low, it usually appears in the bear market or stock consolidation stage, and the market is not active.

Beginners can buy some books to read first, like when I first started to learn, and then study with simulated stock trading. The bull stocks I could use at that time were synchronized with the firm offer, and my knowledge was comprehensive, which would be very meaningful to learn. Wish you success!
