My Side Job is a Trader

　　 "If you write a profit with a probability of 80% or more, wouldn't it be a profit?"

Wang Shen looked at Zhang Xin like an idiot, and said: "How can you say such ignorant things? As far as I know, in the world of quantitative trading, no one has a trading strategy with a profitability rate of more than 60%. This is a trading method that relies on probability to win. Every increase in the winning rate of one point by one point means that you can earn millions, tens of millions or even hundreds of millions of dollars in profits. What I am looking for is a 55% winning rate. Once this is reached Numbers, I will start quantitative trading without hesitation."

　　 Although Zhang Xin is also very curious about quantitative trading, he is not particularly yearning.

　　 He knows that quantitative trading must have some flaws, such as relying on the Internet. If the Internet speed is delayed, it will definitely have a great impact on the transaction.

After the excitement, Wang Shen sighed lightly: "Hey, it's a pity that a reliable trading strategy is too difficult to develop. A qualified trading strategy requires studying a lot of historical data, and finding a regular index among countless technical indicators. Indicators or a combination of several indicators, and then through repeated runs, modify and adjust the parameters until they are qualified, the workload is too much, far beyond the scope of my personal ability."

　　 Zhang Xin suddenly thought of something and said: "This quantitative trading is only applicable to ultra-short-term trading or even over-frequency trading, right? And it only applies to those T+0 trading varieties."

　　 "Of course, after all, it depends on probability to obtain profit. The more transactions, the more profit."

　　 "Like you said, don't those fund companies with team support have the advantage? Then someone will have a dedicated person to formulate a strategy, and then let the programmer write it out, even without the need for a trader."

"Theoretically, this is the case. After all, machines have no emotions. You also know that when trading, the emotions of traders have a great influence on traders. Therefore, quantitative trading completely eliminates human emotions, and the machine will only follow the set strategy. Trading. From this point of view, completing a transaction through a program is simply an explosion of humanity."

Zhang Xin also knows that not mixed with emotion is the biggest advantage of programmatic trading, but everything has advantages and disadvantages. The program is written by humans. It is inevitable that there will be loopholes. Moreover, there are sometimes extreme market conditions in the market, and the program will not act on these extreme market conditions.出处理。 Out processing.

"Of course, even if a reliable strategy is formulated, everything is not going to be all right. A strategy is time-limited and may be applicable for a certain period of time. Once the market trend is different from the history, the strategy will fail, and the market trend is ever-changing. , Just like there are no two exactly the same leaves in the world, the market will be different every day, maybe just similar. So the strategy needs to be adjusted in real time."

　　 "Well, it seems that I overestimated quantitative trading. It seems that there are too many restrictions on quantitative trading, and it is far less flexible than my own trading."

Wang Shen closed the computer and said, "Of course, quantitative trading is only relatively mature abroad. It was brought back from Wall Street two years ago. Therefore, there are not many domestic institutions doing quantitative trading, and the varieties that can be done are limited. More of them are the same as I am now. Although they are in China, they are all international varieties."

　　 Although quantitative trading is good, Zhang Xin has little interest after getting a general understanding. As Wang Shen said, he really opened his eyes today, but he does not want to switch to quantitative trading.

　　 One is that the hardware conditions are not up to standard, and the other is that short-term trading does not conform to Zhang Xin's trading habits.

　　 Zhang Xin is a trader, and has always only done bands. This kind of market is calculated in the sky, which is also in line with his current situation.

　　 Short-term trading requires sitting in front of the computer and watching the market every day, and Zhang Xin can only do trading as a sideline at present, and cannot watch the market all day.

　　 Seeing that the phone is fully charged, Wang Shen washes his face and then prepares to go out.

　　Although I have visited the Bund during the day, the most beautiful scenery of the Bund is still after nightfall. You can only see the prosperous scene of Shiliyangchang after the lights are up.

　　 Back to the Bund again, it was almost five o'clock, Wang Shen proposed to settle the supper first, after eating, just go to the Bund and take a walk along the river.

　　 At noon, Wang Shen said that he would take Zhang Xin for an authentic Western meal, so he checked on his phone and found a Western restaurant on the Bund.

　　 After Zhang Xin's strong opposition, Wang Shen finally took off his socks before going out. Although wearing sandals did not look very elegant, at least it was not a catastrophic aesthetic.

　　 The waiter in the restaurant did not show any slack because of their ordinary clothes. He soon brought the red wine and dessert before the meal according to Wang Shen's request. After agreeing, he helped them unwrap the red wine for sobering.

　　 Waiting for the waiter to walk away, Zhang Xin said distressedly: "You are crazy, a bottle of red wine is several hundred, we only have a few hundred yuan for this meal."

　　 Wang Shen said with a look of contempt: "This bottle of wine is only a few hundred yuan, at most it can be considered a mid-range wine. At any rate, we are also future financial tycoons and capital predators. We can't lose our value."

　　 Zhang Xin was a little speechless, pointing to Wang Shen's clothes, and said: "You also know that you can't drop the price, then you can dress like this to eat Western food."

　　 "This is personality, you don't understand."

　　 "The personality of the fart, I think you have a problem with your aesthetics. Where can girls like you like you?"

　　 After a while, the sirloin steak ordered by the two came up. UU reading www.uukanshu.com

　　 Fortunately, Zhang Xin had eaten steak before, so he would use a knife and fork, otherwise he would be embarrassed if he was appointed.

　　 After eating a large steak, the waiter began to bring other dishes one after another.

　　 Zhang Xin and Wang Shen ate and drank while chatting. Unknowingly, an hour passed, and a bottle of wine was almost drunk.

　　 Zhang Xin is okay. Although he usually doesn't drink alcohol, he is genetically influenced by his natural drinking volume, so if he drank half of the bottle, nothing happened at all.

　　 Looking at Wang Shen again, it's a different situation.

　　 Wang Shen's entire face turned red, and he even had a big tongue when he spoke. A discerning person knew that he was a little drunk.

　　 But fortunately, he is still conscious and can still chat with Zhang Xin.

　　 After eating dessert, drank a cup of sober tea. When Wang Shen was in a little better condition, Zhang Xin settled the bill and helped Wang Shen to walk to the observation deck on the Bund.

　　 Wang Shen refused Zhang Xin to help him, saying: "Don't worry, although my head is a little dizzy, but it doesn't affect walking, let's go to the riverside to blow a hair."

　　 There are a lot more people on the Bund at night, and many of them are taken by tourists from other places.

　　 The two found an empty place, with their backs leaning on the guardrail, looking at a piece of the Republic of China-style buildings along the river, as if they had returned to the era of intoxication.

　　 "It's Citibank over there, right?"

　　 Wang Shen pointed to a Western-style building at the intersection of Jinling Road and asked.

"Yes what's the matter?"

　　 "Remember Zheng Xue from our class? She is now working at Citibank."

　　 "Huh? So amazing? Are you still so concerned about people?"

　　 Zhang Xin was surprised at first, but then he developed a heart of gossip.
