After making trouble for a while, the three of them also leaned on the sofa, Luo Tian looked at the two beauties beside him, not to mention how beautiful they were.

Then Mia asked, "Luo Tian, can you teach me to look at stocks? ”

Mia didn't want to speculate in stocks, she just wanted to learn more, so that she and Luo Tian would have more topics in common.

"You were going to strangle me just now, let me teach you now?Aoxue is an expert, why don't you let him teach you. Luo Tian also pretended to be unhappy.

"Oh, Aoxue is too busy every day, and she is tired when she comes back from work, how can I let her teach me, it's you, I want you to teach me now. ”

Mia ran to the side and grabbed the laptop that Luo Tian had brought home.

"Okay, but it's not open yet, and the trend won't move, so I'll teach you to take a look. ”

Luo Tian took the computer and said it to Mia little by little from the basic place.

Although Yan Aoxue is very familiar with stocks, listening to Luo Tian's explanation, it is also very innovative, as if she can listen to it very clearly, Mia is already smart and clever, coupled with Luo Tian's careful explanation, she quickly understands it thoroughly.

"I understand that now, but what's going on here?" Mia pointed to the closing price of one of the stocks.

"According to what you just said, the closing price is 16.05, if the rise and fall limit is ten percent, and then rounded, the limit for the next day should be 1.61, that is to say, the rise and fall of the next day should be 17.66, and the limit price should be 14.44, but the actual situation does not seem to be like this?" Mia pointed to the price and said suspiciously.

"Yes, yes, you can see it, you go on. Luo Tian nodded.

"The actual situation is that this stock has fallen at 14.45, but according to the data above, it shows that the price limit is indeed 17.66, why is this?" Mia leaned on Luo Tian and asked seriously.

"Come, Aoxue, you can talk about it and explain it to Mia. Luo Tian pulled Yan Aoxue down to his side.

Yan Aoxue looked at it for a minute and said: "According to the increase calculation, the current price must first subtract yesterday's closing price, and then divide it by yesterday's closing price to equal the rise and fall." ”

"The increase is 16.05 times 1.1 equals 17.665, rounding is 17.66, the decline is 16.05 times 0.1 equals 1.605, and finally 16.05 minus 1.605 equals 14.445, rounded to 14.45, if you look at it unilaterally, there is no doubt about the increase calculation, the difference in the decline is 0.005, and the rounding caused by division in the calculation is biased. ”

Yan Aoxue was already an expert, so she could see at a glance where Mia's question was.

"Ao Xue is right, if you want to be bullish now, in addition to the calculation formula, there are also some external factors, including positive and negative news, if you calculate alone, we can also accurately judge. ”

"Suppose the rise and fall is N%, the closing price of the previous trading day is A, and the current price is B, so that you can get A plus A multiplied by N% equal to B after finishing to get N% equal to B divided by A minus 1, here is a point to remember, if N% is equal to 0, it means that the stock has not risen or fallen, if N% is greater than 0, there is a great probability that the stock should rise, otherwise N% is less than 0, that is, the stock should fall. Luo Tian said seriously.

"But you have to remember that calculation is just calculation, can not be generalized, the stock market is unpredictable, there are many traps but also many opportunities, these are all need to be slowly explored, slowly to understand, investment is risky to enter the market need to be cautious. Luo Tian touched the hair of the two girls.

"Husband, you're such a genius. Mia hugged her and kissed Luo Tian the cheek.

"You're just getting started, it's normal to don't know this, you'll know in the future, these are elementary knowledge, you see, Ao Xue is not surprised, do you know why?" Luo Tian said with a wicked smile.

"How do you know that Aoxue is not surprised, maybe she just didn't express it!" Mia winked at Yan Aoxue.

"No, look, you kissed me when you were surprised, and if she didn't kiss me, it means that she wasn't surprised. Luo Tian said cheekily, and turned his head to point to Yan Aoxue's face.

"If you don't take advantage of me for a day, will you die?" Yan Aoxue pinched Luo Tian again.

"Ouch, hey, if you're pinching me, I'm going to spank you. Luo Tian wanted to cry without tears, pulled up his clothes and looked at both sides, he felt a little purple, these two girls were really ruthless.

Yan Aoxue also saw Luo Tian's somewhat purple waist, and also pouted: "Whoever made you always like this, if you don't say a few words and are not serious, you are a scoundrel." ”

"Wow, you're still talking back, aren't you? It looks like you're really going to be served on a large scale. Luo Tian rubbed his hands and shook them in front of Yan Aoxue.

"Don't ...... No, no, no. Yan Aoxue moved back, unconsciously protecting herself with her hands.

"If you don't, then you come and pinch my shoulder, and this matter will be over. Luo Tian hooked his fingers at Yan Aoxue, and then moved his shoulders.

"I don't ......," Yan Aoxue turned her head.

"Why do you always bully Aoxue, if you do this again, I will ....... Mia was on the side to fight for Yan Aoxue.

"You just, what are you doing? You can't run away, this is what you're pinching, right?" Luo Tian picked up his clothes and pointed to a reddened place.

Yan Aoxue and Mia were silent, Luo Tian continued to rub his hands and said, "Now, Aoxue pinched my shoulder, and Mia beat my leg." After saying that, he couldn't help but let himself laugh.

The two women glanced at each other, and really pinched Luo Tian's shoulders and pounded his legs.
