"Success?"

In Zekang's office, after seeing that the index began to fall, Xu Fei still couldn't believe all this in front of him, but soon there was a panicked escape on all stocks, which made him realize that the market had indeed reversed as he expected. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"It worked!"

The index plummeted by more than 300 points, and the number on stock index futures was even greater, especially in IC contracts, which was more than 500 points, which made Zhou Chang'an happy and happy, "I really didn't expect that a single program could make the market plummet." It's amazing, it's amazing! ”

He said "magical" twice in a row.

"It's just a measure of extraordinary times."

After finishing the operation, Chi Zhengyi began to pack everything in an orderly manner, took the tools and prepared to open the chassis, "But this method cannot be used frequently, and it will not be good once it attracts the attention of the exchange." In the European and American markets, there are also transactions that specialize in capturing high-frequency transactions, and they use military microwaves as communication tools, which transmit faster than optical fibers. If it is self-defeating once captured by the other party, the consequences will be unimaginable. ”

"What are you doing?"

Zhou Changan's eyes fell on Chi Zhengyi's busy hand, and he asked strangely, "Why are you going to dismantle the computer now?" This...... What's going on? ”

"I'm going to take the hard drive off and take it back and refine my model to be able to work with more stocks at the same time."

Chi Zhengyi also looked at Zhou Changan strangely, and only after a while did he look at Xu Fei meaningfully, and said slowly, "I can't bring the entire chassis back, right?" Are you right, Mr. Xu? ”

Although he said such high-sounding words as optimizing the model, he actually had another purpose, that is, to keep the model firmly in his own hands, so that it would not be copied and deciphered by others.

Among all programmatic hedge funds, the money-making model is the most important secret, so it must not be leaked. Even if it is leaked, the core data will be changed immediately, and the original model will be targeted for attack in the market.

Renaissance Technology, the world's top programmatic trading hedge fund, once had something similar happen. Two math geniuses from Russia joined Renaissance Technology and helped create a lucrative programming model. But later, after the two resigned from Renaissance Technology, they recopied the model based on their original experience, but immediately lost its magic and became worthless. That's why the core data and the whole operating mechanism are changed, and at the same time these models are sniped.

Although he helped Xu Fei, neither Chi Zhengyi nor Luo Tian had the slightest intention of transferring this model to the other party.

"It's better to ......"

Xu Fei knew this, and was about to open his mouth to buy this model, but after thinking about it, he gave up in despair, he knew very well that this model could only be used at critical times, and there was a great risk of exposure, which was completely a chicken rib for him at present.

He didn't speak, and Zhou Changan naturally didn't say much. The two could only watch as Chi Zhengyi and Luo Tian dismantled the chassis and took away the hard drive in a grand manner.

"What now?"

After the two of them finished all this, they said hello to Xu Fei and Zhou Changan, and then left with Shi Ran. Looking at the backs of the two leaving, Zhou Changan sighed and said to Xu Fei, "Mr. Xu, don't mind, the two of them are this temper, I have already understood it." If it weren't for the fact that they still have some money-making skills, I would have let them out of the way in the morning! ”

"Haha, only those who have the ability have a temper!"

Despite his reluctance, Xu Fei still showed his extraordinary bearing, "Forget it, don't worry about them, let's continue our own business." Even without them, we still make our own money. ”

"Alright, gentlemen, let's have a meeting!"

Slapping his palms twice, Xu Fei shouted to the traders in the audience, "Although with the help of some high-tech things, we have achieved our goal." But that's not our style, Zekang has the core secret of making our own money, and that's all of you. Everyone, let's clean up, and in five minutes we'll have a meeting in the conference room to discuss tomorrow's Friday. ”

"I ......"

Zhou Changan was a little hesitant, he really wanted to participate in this meeting, but he was worried about his identity as an outsider, so he couldn't help but say tentatively, "Can you also participate?" ”

"You?"

Xu Fei looked at Zhou Changan with interest, clearly caught the enthusiastic expectation revealed in the other party's eyes, and nodded after thinking about it, but still warned, "You can watch from the sidelines, but don't make a sound." ”

Zhou Changan looked happy and nodded heavily.

Five minutes later, Zekang's conference room was full, and the traders waited quietly for Xu Fei to start, and no one exchanged heads, which made Zhou Changan feel inexplicably nervous.

"I believe you have seen today's market, the market has reversed throughout the day, and it has risen first and then suppressed very obviously."

Xu Fei, who was sitting in the middle, pondered for a moment, knocked on the table and said slowly, "Everyone should be very curious, why is there such a market?" Also, what did I just mean by high technology? I'll tell you what the hell is going on. ”

"The two traders just now are high-frequency traders who Mr. Zhou poached from overseas. I believe everyone is familiar with high-frequency trading. A model they just made is to send a large amount of trading instructions to the exchange in a very short period of time, resulting in a rapid rise or fall in the stock price, you should be very clear about the operation mechanism of matching transactions, a large buy or sell order in an instant to sweep the order above or below the price, this is the reason. ”

"But the difference is that the deal doesn't really work out. The wonderful thing about high-frequency trading is that it can change the stock price in the fastest time, but it doesn't actually trade. Because these orders will be taken down quickly before the exchange issues a trade order, forming a false market trend, which is the whole reason why you are seeing the stock price fall so quickly. ”

"This program is revolutionary and disruptive, but similar situations appear in the market again and again, and they will definitely be noticed by the regulators, who will close such a loophole sooner or later in the future."

After looking around and taking in the trader's reactions, Xu Fei nodded with satisfaction, and then said in a fierce voice, "So gentlemen, a program can only be a program, and it can never replace your wise brain." Only when ingenuity and program are used in combination can the power be maximized. ”

"Now that we're on the formal agenda, does anyone say what to do tomorrow? By the way, tomorrow this program will continue to be used. ”

The reason why Xu Fei added such a sentence is to tell everyone here that tomorrow will still be a bearish market.

"Today's strange market will definitely have a plausible explanation."

A tall, Chinese-faced trader stood up and said in a loud voice, "If we continue to use it, I'm afraid it won't have the magical effect it has today." Or even if it had an effect, it wouldn't be as exaggerated as it is today. So we have to create another kind of emotion that will affect the market as much as possible with this process. ”

"Cheng Zhonghua, what do you think?"

Hearing the trader's words, the others nodded in unison, and it was true, Xu Fei even asked by name, "I know you said this, you must have an idea in your heart." Give your opinion and let everyone refer to it. ”

"Good!"

I saw that the trader, who was about 30 years old, nodded, and then said loudly, "The stock index plummeted from 4,700 points to below 4,500, and there was a spectacular situation of 1,000 shares falling to the limit. In the following two trading days, under the positive stimulus and rebound, it returned to around 4700 points. This looks like a surprise attack by the bears, and if we hadn't had our disruption today, maybe the stock index would have been able to get back to where it was. ”

"But unfortunately, we changed all that, and today the index plunged again. Think about it, although there are all kinds of good and bad news in this process, what is the most affected group of people? ”

He threw out a serious question, and everyone couldn't react for a while, and there was a collective speechless stop, and they all fell into deep thought.

"I have some news here, please refer to it."

Cheng Zhonghua held a piece of paper high and said, "There are some contents that everyone should know, there will be 28 newly listed companies next week, and tens of billions of frozen funds will be frozen; Newly opened securities accounts fell by more than 30% month-on-month; Pension listings, continued decline in the crude oil market, and other recent news that may affect the stock market. In addition, there is another market speculation, that is, the RRR cut. But until the news is confirmed, we will not count this news for the time being. ”

"Although there is so much news, there is only one factor affecting the market at present, and that is the financing market."

His voice gradually became louder, "The market crash three trading days ago was triggered by the news that the rumors touched the closing line of the financing order. We don't know the specific situation, but it can be expected that the loss of a large area of 1,000 shares, even if it is a financing plate with twice leverage, will probably be close to 20%, which is a very terrible number whether it is placed on retail investors or between our institutions. ”

"In fact, the two-fold leverage is just on-site financing, and the off-market financing leverage can be higher than this, generally around three times, or even five times the high leverage. In the crash three trading days ago, I believe that most of these financing orders did not escape, and the rumors that triggered the liquidation were definitely not rumors, but everything that actually happened. ”

"If you want to continue to fall tomorrow, the financing market will be a huge force that cannot be ignored, especially after the two-day rebound, the financing market that has narrowed some of the losses may not have the heart to fight in this market. Today's decline at the end of the session is the loudest alarm bell for them, telling them that if they don't leave the market, they will lose to the bottom. ”

"So I think the most important thing for us at the moment is to spread the news in the market that is not conducive to financing, such as some people are financing stock speculation and jumping off the building, Homes is under greater pressure from the regulators, isolating their network interfaces, and even the real-name joint sitting system of umbrella trusts. As long as the financing market is in turmoil on its own, the entire market will collapse. ”

"Among the three nearby provinces, Mr. Xu, you have absolute prestige, enough to convince those super big families. If Mr. Xu comes forward, I believe that these news will spread very quickly, and the funds that can be affected are quite large. We can even pretend to be Xu's name and directly publish articles on the Internet that are worried about the financing market, in short, in this night, the entire market is agitated. ”

"Even I took advantage of it?"

Xu Fei's heart had been convinced, and he humorously pointed to his nose and feigned anger, "Every time Cheng Zhonghua has a good strategy, he always pulls me up, and this time is no exception." ”

"No way, those who can work hard!"

The audience let out a burst of good-natured laughter, and in the midst of the laughter, Cheng Zhonghua touched his nose awkwardly and explained, "Mr. Xu's name is the weather vane of the market, and if such a thing is not used, it is simply a tyrannical thing." (To be continued.) )
