1. In the stock market, the lightning diagram, also known as the minute transaction diagram and the dot matrix diagram, is a graph that lists and displays every transaction in the futures trading market. Mainly used for ultra-short-term speculation in the day, there are basically no technical indicators, mainly relying on the sense of speculators. Tick chart means that every transaction is displayed on the chart, which is often used for intraday short-term trading. But it doesn't make sense to stocks, because stocks are T+ 1 transactions, so it is useful to make futures reference tick charts. 2. The lightning chart is the displayed price of each transaction in the connected transaction chart. This price change is due to the record of the price of each transaction. So it's pretty fast. On the time-sharing interface, press F8 to switch to the lightning diagram, and then press F8 to switch back to the time-sharing diagram. Remember to press F8 in the time-sharing interface. If it is in the K-line interface, F8 means cycle switching. The switch between time-sharing chart and K-line interface is to press F5.
