My Side Job is a Trader

"If you write a book that can make the transaction profitable with a probability of more than 80%, wouldn't you be making money?"

Wang Shen looked at Zhang Xin like an idiot, and said, "How can you say such ignorant words? As far as I know, in the world of quantitative trading, no one has a trading strategy with a profit probability of more than 60%. A trading method that relies on probability to win. Every time the winning rate increases by one point, it means that you can earn millions, tens of millions, or even hundreds of millions of profits. What I am pursuing now is a 55% winning rate. Numbers, I wouldn't hesitate to start quantitative trading."

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

He knows that quantitative trading must still have some flaws, such as being particularly dependent on the network. If there is a delay in the network speed, it will definitely have a great impact on the transaction.

After the excitement, Wang Shen sighed lightly: "Hey, it's a pity that it's too difficult to formulate a reliable trading strategy. A qualified trading strategy needs to study a large amount of historical data, and find regular indexes among countless technical indicators. Indicators or a combination of several indicators, and then through repeated operations, modify and adjust the parameters until they are qualified, the workload is too large, far beyond my personal ability.”

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

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

"As you said, don't those fund companies with team support have an advantage? At that time, they will have dedicated people to formulate strategies, and then let programmers write them out, and they don't even need traders."

"In theory, this is the case. After all, machines have no emotions. You also know that when trading, the emotions of the trader have a great influence on the trading, so quantitative trading completely removes human emotional factors, and the machine will only follow the set strategy. Make a transaction. From this point of view, it is almost impossible to complete a transaction through a program.”

Zhang Xin also knows that being free from emotions is the biggest advantage of programmatic trading, but everything has advantages and disadvantages. Programs are also written by humans, so there will inevitably be loopholes, and sometimes there will be extreme market conditions in the market, and the program will not do anything to these extreme markets. out processing.

"Of course, even if a reliable strategy is formulated, everything will not 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 history, the strategy will become invalid, and the market trend is ever-changing. , Just like there are no two identical leaves in the world, the market will be different every day, and may only be similar. So the strategy needs to be adjusted in real time."

"Well, it seems that I overestimated quantitative trading, so it seems that there are too many restrictions on quantitative trading, and it is far less flexible than trading by myself."

Wang Shen closed the computer and said: "Of course, quantitative trading is relatively mature abroad, and was brought back from Wall Street in the past two years, so there are not many domestic institutions that do quantitative trading, and the varieties that can be done are also limited. More are still the same as I am now, although they are in China, but they are all international varieties.”

Although quantitative trading is good, after Zhang Xin got a general understanding, he was not interested. As Wang Shen said, today he really opened his eyes, but he didn't 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 has always traded in the band, and this kind of market is calculated in days, which is also in line with his current situation.

Short-term trading needs to sit in front of the computer and watch the market every day, but Zhang Xin can only do trading as a side job at present, and cannot watch the market all day long.

Seeing that the phone was fully charged, Wang Shen washed his face and was ready to go out.

Although I have visited the Bund during the day, the most beautiful scenery on the Bund is after nightfall, when the lights are on, and you can see the bustling scene of Shiliyangchang.

Back near the Bund again, it was almost five o'clock, and Wang Shen proposed to go and settle the dinner first, so that he could go to the Bund for a walk along the river after eating.

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

After Zhang Xin's strong objection, Wang Shen finally took off his socks before going out. Although wearing sandals didn't look very elegant, at least it wasn't a catastrophic aesthetic.

The waiter in the restaurant did not show any slack because of the ordinary clothes of the two of them, and quickly served the pre-dinner red wine and dessert according to Wang Shen's request, and after agreeing, opened the red wine for the two to sober up.

When the waiter walked away, Zhang Xin said with some distress: "You are crazy, a bottle of red wine costs hundreds of dollars, and our meal is only a few hundred dollars."

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

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

"It's called personality, you don't understand."

"Fart's personality, I think it's because you have a problem with aesthetics, how can there be girls like you like you."

Not long after, the sirloin steak they ordered was served.

Fortunately, Zhang Xin had eaten steak before, so he would use a knife and fork, otherwise he would make a fool of himself.

After a large steak was finished, the waiter began to bring other dishes.

Zhang Xin and Wang Shen ate, drank, and chatted. Before they knew it, an hour passed, and the bottle of wine was almost gone.

Zhang Xin was better. Although he didn't usually drink alcohol, due to genetic influences, he was born with a good capacity for alcohol, so he drank most of the bottle and nothing happened.

Looking at Wang Shen again, it was a different situation.

Wang Shen's entire face turned red, and he even spoke with a bit of a tongue. Anyone with a discerning eye could tell that he was a little drunk.

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

After eating dessert, he drank a cup of hangover tea, and when Wang Shen was in better condition, Zhang Xin paid the bill and helped Wang Shen to walk to the viewing platform on the Bund.

Wang Shen refused Zhang Xin to help him, and said, "Don't worry, although my head is a little dizzy, but it doesn't affect my walking, let's go to the river to blow some air first."

There are a lot more people on the Bund at night, and many of them are tourists from other places who come here to take pictures.

The two found an empty seat, leaned their backs against the guardrail, and looked at a piece of Republican-style buildings along the river, as if they had returned to that era when people were intoxicated.

"Is that Citibank over there?"

Wang Shen asked, pointing to a western-style building at the intersection of Jinling Road.

"Yes what's the matter?"

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

"Ah? So powerful? Are you still so concerned about others?"

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