The autobiography I wrote cannot be a tragedy

Magic City, a certain quantitative operation team.

In the employee area, rows of screens are filled with constantly changing K-line charts.

But there were not many employees present, only the servers in the computer room were humming with heat...

Why is it that now that the market seems to be getting better and better, it is getting harder and harder for investors to make money?

The answer is simple, stragglers can never defeat regular troops.

In the past, institutions used professional traders to cut leeks, but now they use the program code of quantitative models to cut leeks. Times have changed, and cutting efficiency is higher.

When you think you are still in PVP and your opponent is a big guy in front of a computer screen, you don’t know that your biggest opponent is already a server...

And when you realize that you are in PVE, you will soon find in despair that your highest hand speed is not even a fraction of the opponent's APM (operations per minute).

Ordinary people challenging computers may be able to defeat beginner, advanced, expert, or even hell-level robots.

However, the next second, the programmer will tell you that there is no upper limit to the difficulty of the robot...

The only opponent of robots is robots!

In the future capital market, the opponent of quantitative trading will only be another quantitative trading...

"Mr. Wei, this...this is our income statistics table for this week."

The middle-aged man, wearing a suit and leather shoes and wearing Cartier, looked like an elite, while drinking coffee, he casually took the report carefully handed over by his subordinate.

However, as soon as he glanced at it twice, the coffee in his mouth almost spit out.

"-6.2%!?" Mr. Wei's face turned green.

"Are you sure you're not kidding me?"

"This..." the subordinate said cautiously with a worried look on his face, "I have done the statistics three times, the data must be correct..."

"Pah!" Mr. Wei said angrily as he threw the report directly on the table.

"Are you kidding! I just went to Hainan for a week's vacation, and you're going to give me this kind of result when I come back?

I lost more than 30 million yuan in one week. How do you want me to explain it to investors?

Tell me, what was the company's weekly profit rate before I left? "

"On average -1%~3%, if you are lucky, it can even reach 5%..."

"What about now? Are we experiencing a stock market crash?" Mr. Wei said angrily, slapping the table.

The subordinate smiled bitterly.

"Mr. Wei, we didn't expect this. Everything else is fine. The main reason is that we suffered heavy losses on one stock."

"Huh? Which evil stock is so evil?" Mr. Wei picked up the report and read it carefully with an angry look on his face, and soon found the culprit who caused them heavy losses.

The green “-26.8%” at the back is extremely dazzling.

"Xu's Group?"

The subordinate gritted his teeth and said, "Yes, that's it. Most of our negative returns are on this stock. Even if other stocks have a slight profit, the overall loss will be greatly increased.

To be honest, not only our team, but also our peers who have this stock in several markets next door are also lamenting that we are pretty good, and the quantitative strategy is not that radical.

I heard that Mr. Liu’s 50 million plate was immediately announced to be liquidated yesterday..."

"Hiss~" Mr. Wei gasped.

"What's going on with the Xu Group? Although the real estate industry is in a slump right now, it's not like this, right?

Could it be that there was some unexpected breaking news? "

"That's not true, except that the Xu Group has just issued a positive announcement about repurchasing shares, which shows that the situation is calm, and even the stock price has not fluctuated significantly.

But the evil is here.

Our quantitative model used to be fine before, but recently it has been showing negative returns for a week in a row. "

"Negative returns? What does the technical team do for a living? Since there is a problem with our quantitative strategy, why don't we quickly modify and maintain it?"

"We maintained it, but it would have been better if we didn't. If we maintained it, we would have lost more..." The subordinate smiled bitterly.

Mr. Wei stared blankly for a long time before forcing himself to calm down.

"Have you found the reason?"

"Well... although I can't be sure, looking at the trading volume, this stock should have a new heavyweight quantitative player, and the trading funds mobilized are at least 1 billion and upwards."

"One billion?" Mr. Wei was stunned for a moment.

This amount of funds... is not too much, but too little!

You must know that Xu Group is a listed company with a market value of nearly 100 billion, with more than 30 billion in circulating shares alone.

According to the standard of 30% for mild market control, the amount of funds must be at least about 9 billion.

A person with a capital of 1 billion can only be considered a big player at best, and is far from the level of a banker.

In nature, quantitative trading is the use of short-term high-frequency operations to obtain large spread profits.

Its profitability depends not only on the excellence of the quantitative model, but also on the amount of funds.

Big fish eat small fish, and small fish eat shrimps, even for quantitative teams!

"That's it, you're going to beat us to nowhere? Our technical team, which we support tens of millions of dollars every year, can just come and knock you down?" Mr. Wei said angrily.

"This..." The subordinate was speechless.

Our team was not the only one who was killed. It was almost like killing the wrong ones and not letting them go. They would die if they touched each other, and if they were next to each other, they would die...

This opponent is quite speechless.

In their circle, they used to play PVE very well, and it was great to cut leeks.

Who knew that someone from EVE would come in and attack them, instead of cutting leeks, they would just chop melons and vegetables.

Although they are opponents, as a technical staff, they have to admit defeat, otherwise how can we say that they are skilled and bold.

With 1 billion yuan in funds, they crushed a group of quantitative teams.

That means that the opponent's strategy model is good enough to offset the other party's financial advantage to some extent.

No matter how you look at it, this guy is not someone you can easily mess with…

“Well, Mr. Wei, although I don’t know who this mysterious player is, he seems to be only interested in the stock of Xu Group.

Our technical department’s suggestion is to stop loss in time, bypass this stock, and readjust our quantitative model.”

“Stop loss? With a loss of more than 30 million, how do you want me to write the year-end report to the shareholders?”

“But… there are so many leeks in the market, we don’t have to hang ourselves on this tree.”

“No buts, there are thousands of leeks, I have to cut this one today!

Humph! A player at the 1 billion level, he is a fierce dragon crossing the river, and he has to peel off a layer of skin before he leaves our Huangpu River!”

Mr. Wei does have the confidence to say this. Although their team size is only medium, the investors behind them are not ordinary people.

Pick one out at random, they are all well-known and influential figures in the Yangtze River Delta.

Even Xu Jinsong of Xu Group is considered a person in the same circle.

As far as this stock is concerned, it is definitely their home ground. Whether to release good news or bad news is up to them, and they are not afraid of the other party making a fuss in this regard.

He immediately took out his mobile phone and sent a "jianghu call" in a chat group called "Qilin Club".

That night, the heads of dozens of investment institutions secretly stayed in the most luxurious private club in Magic City until the early morning...

...

Just after 9:30 the next day, Gao Yuan, who was checking the company's development information, suddenly received a reminder from Ling.

"What? The strategies of dozens of quantitative teams have converged..."

Gao Yuan was slightly stunned, and then thought about it for a while, and then reacted.

This is a one-on-one fight, so the six major sects besieged Guangmingding...

If you can't beat EVE, just play EEEEEVE!

This is a bit of negligence on her part. She focused all her attention on dealing with Xu Jinsong. Unexpectedly, the movement was too big and it actually affected innocent people.

Those big and small fish that were affected were obviously dissatisfied with their new player who had come in...

"Is it troublesome?"

[It's troublesome, but it's even simpler. ]

"Oh? How do you say that?" Gao Yuan asked with interest.

[The trouble is that with the opponent's capital, ordinary trading strategies are already difficult to shake the opponent. Whether it goes up or down, the opponent basically has the final say.

From the current situation, the opponent seems to want to take advantage of the good news of Xu Group's share repurchase to raise the stock price.

This morning, Xu Group's stock opened high and went high. The current stock price is 21.9, and the increase has reached 4 percentage points. ]

Gao Yuan nodded. No matter how good the trading strategy is, it is just a matter of using technology to win.

When the opponent's weight is too high and exceeds a thousand pounds, your four ounces can't move it.

"What do you mean by simple?"

[The simplicity is that our biggest opponent has changed from dozens to one, which makes it easier to predict.

And I have reversed the opponent's trading model through the opponent's trading data, and thus found the opponent's trading loopholes.

Do you still remember the British trader named Navinder Singh Sarao that I mentioned to you? 】

Gao Yuan was stunned for a moment, and her eyes twitched slightly.

"You mean... Flash Crash?"

[The answer is affirmative. 】

"How far can it be done?" Gao Yuan's eyes showed a hint of excitement.

Unlike a certain behind-the-scenes boss whose name is wave-like but whose strategy is relatively conservative, Gao Yuan, who seems to be extremely steady in doing things, has always had an uneasy heart.

[I can only say that the maximum limit on the rise and fall has limited my performance. 】

"Well... arrogant! But I like..."

...

Modu.

"What is the other party doing?"

Only one day later, President Wei's face no longer showed panic, and he restored his calm personality. He sipped coffee leisurely in front of his subordinates, and his eyes were full of confidence.

With the entire technical team, his employees were now concentrating on the fluctuating market on the dozen or so screens in front of them.

"Not yet... Wait! There is!"

Mr. Wei leaned forward slightly.

"The other party... The other party is selling the chips in his hands, very quickly! In just a moment, he has sold 30,000 lots, with a total amount of 60 million!"

On the fluctuation curve, the stock price was visibly falling, but it was soon pulled back slowly...

"Mr. Wei, our strategy is bullish, and the quantitative model is constantly eating the chips thrown by the other party to maintain the stock price!"

The trader's forehead was sweating, and his fingers were shaking.

God has mercy on him, he usually only operates 30 or 40 million funds at most, and today's big scene is the peak of his life.

"Let him sell, ha! Does he think that if he sells the chips in his hand, he will have a chance to get them back?

Keep pushing up the stock price. If the other party leaves, it means he knows what's good for him. If he still wants to buy it, then sell it back and let the other party take it at a high price!

I will tell him today that in the face of absolute strength, all resistance is futile! "

The stock price continued to hit new highs with the influx of huge funds, and soon reached a high of 22.6. As soon as the market opened in the afternoon, it continued to rise, and the increase soon reached a high of 8%, as if it was about to hit a daily limit for you to see.

However, just when Mr. Wei saw that the other party had not taken any action and thought that the other party had finally given up, the stock price suddenly began to fall slowly again.

It fell directly from 8% to 7% in just a few minutes.

"What's going on?" Mr. Wei frowned.

The technicians quickly made several calls and replied quickly.

"Mr. Wei, someone is shorting this stock through securities lending and options. It should be the other party's hand! "

Mr. Wei was stunned.

What the hell, not only did he throw away the chips in his hand, but he also shorted them. How confident are you?

However, before Mr. Wei could react, the stock price slowly pulled back by 8%.

Obviously, it was their quantitative strategy that was continuously buying in.

"How much money have we used so far?"

"About 30%." The trader answered immediately.

With enough bullets, Mr. Wei was relieved and sneered.

"Ha! Okay, okay, you won't cry until you see the coffin, right? Take it for me, we will buy as much as they sell, and pull the stock price to the limit!

I want to see how much money they have to fight against us! ”

In the face of "absolute strength", the stock price on the market is like a rocket, rushing straight to the 10% daily limit!

Looking at the rising stock price, President Wei finally showed a smug smile.

This wave of daily limit, the other party must lose at least 2%, do you think that's the end?

As soon as the market opens tomorrow, he can directly pull another daily limit, or even several consecutive daily limits!

You must know that securities lending and options are leveraged. A loss of more than ten points, if placed on the other party, may directly lose half of the principal.

The boldest gambler would probably be scared to death at this time, and run away.

And the biggest winner is undoubtedly them who ate the other party...

This wave, at least several hundred million will be earned, cool!

"Hehe! Today they are smart, knowing that they can't beat them, and they didn't even use quantitative models to confront us.

It's still you, President Wei, who are superb, one move and one force to defeat ten skills, and you made this difficult opponent embarrassed and returned in defeat. "

When his subordinates saw that Mr. Wei was in a good mood, they immediately flattered him, making Mr. Wei's chubby face smile even more.

It was almost 3 p.m., and the stock market was about to close.

Before Mr. Wei could consider whether to celebrate with champagne or Maozi in the evening, he just glanced at the screen casually...

"Swish!"

A straight green column suddenly appeared in his retina without any warning...

Mr. Wei's smile stopped abruptly.

His eyes were wide open, almost popping out.

He rubbed his eyes hard with an incredible look on his face, and then continued to be stunned.

The whole person just opened his mouth, as if petrified and motionless.

Others also noticed Mr. Wei's abnormality, looked at the screen in confusion, and then...

A group of stone sculptures of the same style appeared on the scene.

"What's going on? How could it drop to the limit in an instant! ”

Mr. Wei, who had reacted, grabbed his subordinate’s collar and shook him madly.

Flash crash! This is the first time I’ve seen it in my life!

But I don’t want to witness such history!

A trader on the side was busy checking the background data and was immediately scared out of his wits.

“Mr. Wei…Mr. Wei! It’s…it’s our quantitative model. Our quantitative model is selling madly.”

“What?”

Mr. Wei, who thought it was the opponent’s huge order, was petrified again when he heard this.

I thought it was the opponent who was too cruel, but it turned out that I was the murderer?

“What’s going on? Our model is crazy?” Mr. Wei roared.

“No…no, someone used a huge amount of pending orders to mislead our model, which made our model have the illusion of a stock price collapse, so it sold madly.

Because the speed of placing and withdrawing orders was too fast, the stock price was instantly hit to the limit.

The opponent…the opponent seems to have found a loophole in our model! ”

“What? ! "

Mr. Wei is so Spartan, there is such an operation!?

Life is full of ups and downs.

When you think you are in EVP, they quietly switch you back to EVE, and let you feel what despair is...

Yes, your own funds have an absolute advantage.

However, the opponent tells you what absolute strength is on another technical level...

"Why don't you quickly close the model and switch to manual operation! Pull the stock price back to me!"

There was no time to be shocked, Mr. Wei roared and wanted to remedy it.

Calm down, as long as your funds still have an absolute advantage, then the limit down is only temporary...

When the time comes, the stock price will be brought back the same way it fell.

However...

"It's too late. The other party took advantage of our mistakes and closed all the previous short positions. We have already generated a huge amount of transactions near the limit down..."

The next sentence the trader said with a sad face made him fall into his chair, as if he was falling into an ice cellar.

It's over...

It's all over...

"Click!"

At this moment, the clock hand on the wall also jumped and pointed to three o'clock...
