As soon as the phone was connected, the other party said bluntly after hearing the meaning: "Risk audit is indeed set up to prevent invalid orders and wrong orders from interfering with the system...... In the next step, we will improve, mainly for the sake of stability. ”

Chang Tianhao heard it clearly next to him, so he said, "Can you temporarily cancel the account and try it?"

When Wang Huiling told the other party about this request, the other party agreed, but reminded that it was impossible to cancel for a specific account, and that if you want to cancel, you will cancel it all, but it may lead to system instability, and they are still making improvements and attempts, but they agreed to run it for 20 minutes.

So after the other party announced the cancellation, Chang Tianhao used the account to try to order, this time the signal delay was compressed to 2 seconds, this is normal logic, after all, the current network transmission speed and operation mechanism are still relatively primitive, there is a normal delay, no delay is abnormal.

Even when the technology matures, the delay still exists, only how much, and the delay of the exchange to the interface of each market is not exactly the same, which does not matter to ordinary people, but for capital predators and high-frequency automated trading, delay is a matter of life and death.

Especially in stock trading, this delay is even more prominent because of China's unique reporting mechanism and price limit restrictions. Therefore, the rent of some office buildings near the computer rooms of the two exchanges in Shanghai and Shenzhen is very expensive, and there are still securities companies that are happy to rent and install servers.

If you travel 0.3 kilometers in microseconds and send a signal at the same time, can the time taken from Urumqi to the computer room of the Shanghai Stock Exchange be the same as the speed from another street in Shanghai to the computer room of the Shanghai Stock Exchange?

This is the reason why you can't grab the food in front of the price limit or list the goods before the price limit when the stock is placed every day - when the price is consistent with the price limit, the time priority is to distinguish to the microsecond or at least the millisecond level! You may be lower than the channel speed of other large customers within the brokerage, and the brokerage company that provides services for you is likely to be lower than the channel speed of other brokers.

Don't think that microseconds are great, the speed of computer memory is nanoseconds, one nanosecond = one billionth of a second, and in the era of Chang Tianhao's rebirth, most SDRAM speeds are no more than 10 nanoseconds.

After the second test, Chang Tianhao was relieved: the current ISDN network data transmission speed is not as good as in the sales department, coupled with the review of the order signal, 4-5 seconds is still relatively smooth, he said, "So I have the bottom of my heart......

Wang Huiling asked, "Did you suspect anything at first?"

"It's a bit skeptical, indeed...... But now doubts can be ruled out. ”

"What were your initial suspicions?"

"I'm worried that someone has obstructed the Dadi Futures software and buried a backdoor or Trojan horse program......"

Wang Huiling was puzzled: "What is this picture for? Eat your price difference? This is also impossible, you basically use limit orders." ”

"You can't eat anything from the price difference, it's ......the trouble to eat the data," Chang Tianhao said in a low voice, "If I'm a big guy and need to place thousands of orders in one go, and my competitors get my instructions 3-5 seconds in advance, guess what will happen?"

Wang Huiling gasped and muttered, "Isn't that ...... Isn't it ......?"

"So you can't hurt people, you can't have the heart to prevent people, the ghost knows if there is a problem with the software, I need to take a small account to test it first, and now it seems that everything is normal, it's completely technical reasons......"

"How do you know everything?" Wang Huiling looked adoring, "I don't feel like there's anything you don't know, obviously in your 20s, but you look old and cunning......"

Chang Tianhao thought to himself: If you pay too much tuition, you will naturally know! But you can't tell the other party, so he smiled: "I also don't know, for example, I don't know how heavy you are......"

"You hate it, people have been sitting on your lap for so long, how can you not know?"

"Well, that looks like 118 pounds. ”

"Nonsense, how can I be so heavy, people don't even have 100 pounds!"

"This is not scientific, 100 pounds is very thin, how can it be so big?"

This teasing meaning can no longer be heard, then it is really in vain to be a woman, Wang Huiling blushed shyly, and drilled into his arms tighter with a "uh-huh" sound, a pair of eyes were confused, and deliberately twisted his waist, as if to say: "Whether it is real or not, you will know if you try it." ”

Chang Tianhao smiled, hugged her straight, and scraped her nose playfully: "Okay, you wear so little, don't you just want me to see more clearly......?"

"You hate it!"

"Well, then I'll let go quickly......"

He was just about to let go, but Wang Huiling took the initiative to stretch out her hand and hug him tighter: "It's Christmas soon, how are you going to spend it?

"I almost forgot, I have a friend from Beijing in two days, and we will receive the next ...... together when the time comes" Chang Tianhao leaned over, his lips were already on her ear, and the heat sprayed on the face of the goblin in his arms as soon as he spoke, "On Christmas Eve and Christmas, you can arrange it in the company, and then send you some New Year's gifts and benefits, my girlfriend may also come to the company, and then have a meal with friends in Beijing, and everyone will go shopping together in the evening, sing songs, and feel the festive atmosphere......"

Wang Huiling nodded in agreement, although he politely rejected his proposal, but at least he also took into account his emotions, and of course, more importantly, took it to gently remind himself of the fact that he had a girlfriend. Ambiguity is ambiguous, and the nature of exceeding the bottom line is different, she can understand this truth - the more Chang Tianhao is like this, the more she feels that this villain is charming.

Isn't this a kind of "first ...... But...... Of course" what about the narrative structure?

At the end of the day, Chang Tianhao clapped his hands with satisfaction: "Okay, the first goal has been achieved, 400 orders have been placed, I have a class tomorrow, you go to other sales departments to continue, just keep in touch with me during the next process." ”

"How much?"

"The strength is controlled by yourself, the disk trend is not large, less down, if the trend is violent, it will be more, not more than 2000 ......"

Chang Tianhao expected that the trend on the 22nd should be a steady rise, but his prediction was completely wrong, as soon as the morning opened, the price pulled straight up, and he opened a position yesterday with a loss of 32 yuan / ton of 400 hands GN05 contract, which was reflected in the account is a loss of 120,000. With the rise in prices, the market fell into a white-hot state again, and the overall position of the three main contracts exceeded 600,000 in one fell swoop, and Feng Yimou had another 20,000 short orders, and at least two-thirds of these 20,000 short orders were eaten by Han Jun, and the other third fell into the hands of Nanyang Gang.

Chang Tianhao is just a small loss, Feng Yimou's loss is big, the short position he has established has exceeded 60,000 orders, the use of margin has exceeded 110 million, and the floating loss has exceeded 40 million, converted to a loss of 70 yuan per ton - today's wave of 32 yuan growth is the main source of his loss.

Not only is there a crisis in his margin account, but more importantly, there is a crisis in his confidence and reputation: others respect him as the leading brother because of his brilliant past performance, but this time he insisted on going short in the rising stage, which caused many people to be puzzled and unsupported. This crisis of confidence is more harmful than a liquidity crisis on the market!

At this time, the benefits of Chang Tianhao's light position on the left side were reflected, Wang Huiling easily increased the position to 1,500, and at the end of the day, the overall book loss was more than 300,000, compared to the total amount of 18 million, the proportion was indeed very small, and it was not as uncomfortable as Feng Yimou at all.

As for the suspicious voices in the sales department, she didn't bother to pay attention to them, just smiled and ran away: Chang Tianhao is right, you don't have to blow up the warehouse to educate them, they will never understand the truth, and the lesson that you don't need to exchange for real money is not a lesson, it's just a theory - what's the use of just understanding theory?

On the 23rd, the price rose by more than 10 points again, but the increase in positions on the disk was not large, Wang Huiling increased the overall position to 2,000 according to the requirements, and the book floating loss expanded to more than 500,000, she was a little anxious, but Chang Tianhao relieved her not to worry, this loss is a drizzle, the important thing is that he confirmed that the market is indeed in a state of the end of the strong crossbow.

In fact, Hua Rong also severely criticized Feng Yimou's actions, thinking that he was too anxious and reckless, and said that he would add slowly and take small steps, you have taken a position to more than 60,000 in less than 5 days, what do you want to do?

Feng Yimou lowered his head and accepted the criticism, and there was no way not to accept the criticism, because his margin had been in crisis, and the shocking floating loss on the book had made him dare not look at it, he knew in his heart what the number was, but he just didn't dare to face it directly. For the sake of his sincere attitude, the military advisor gave him an idea, and Feng Yimou was suspicious, but he still agreed to do it.

December 24 is Christmas Eve, and it is Friday, which coincides with the last trading day of the week, and the market has shown a rare sign of reducing positions - Feng Yimou closed more than 10,000 orders according to Huarong's suggestion, reduced his position to more than 40,000 yuan, and maintained vital room for maneuver - otherwise if he continues to pull it hard, his position may be liquidated next week.

Because the main force of the bears reduced their positions, the market price continued to rise, and Chang Tianhao quietly asked Wang Huiling to increase the position to 3,000.

Now his overall loss is nearly 900,000, Wang Huiling herself is a little worried, and everyone in the sales department thinks that she is making a big mistake, but Chang Tianhao didn't take it to heart, and told her very firmly: "Don't panic, you will change the market next week, this is the last madness!"

"But I'm a little scared. ”

"Don't be afraid, I'm here...... Isn't it 900,000 yuan? It's only a 5% loss!" Chang Tianhao smiled, "It's closed, you send me all the cars, and I'll pick up people......"

"I'll go with you!"

"You don't want to go, you're the boss, how can you do it? I'll go almost, you have to be reserved, and you'll leave early in the evening." ”

She coquettishly said: "But people want to stay with you for a while, Christmas Eve......"

Chang Tianhao scratched his scalp: "Linda, my girlfriend is here, it's hard for me to do you like this." ”

"Then you'll have to compensate me ......"
