recently there is a demand to make a transaction K chart
Day K is understandable, and the meaning of each square is relatively clear
however, K or even minute K is more difficult to understand. The top and bottom of the box is the opening and closing price according to different circumstances, and the highest and lowest point of the shadow line is always the highest and lowest price. So take the minute K line as an example, should the corresponding square, opening price and closing price per minute be understood as the first and last transaction in this minute, and the highest and lowest prices are the highest and lowest prices in this minute?
A front-end person is not familiar with this aspect. If you have used tradingview or echarts to do relevant requirements, can you introduce it? I feel that it is too difficult to understand the relevant materials.
