Electrocardiography (ECG)

"Simple. Let's begin right away." Gu Feifei nodded and began drawing lines on the stock curves like an ECG. "Watch carefully. We have to find the median line. This opening price will do."

Then, she removed the thresholds below and sold 20,000 lots at the opening price of 21.21 at once. At the same time, she bought 30,000 lots at 21.20.

At this moment, the stock price fell to 21.21. It was difficult for it to fall below this price—the curve on the stock's graph began to move horizontally…

"Then, we will lock the highest and lowest point." Gu Feifei touched her chin. "The fluctuation of the stock market is generally about 15%. If it's higher than that, it will be suspended. We will set it to 6% below and 6% above. This is easier to calculate."

She locked 50,000 lots at 22.40 and bought 50,000 lots at 21.00.

At this time, the curve of the stock's graph was placed in the middle position.
