Back in the dormitory, Wang Nuo continued to think on his own.

The four elements of technical analysis are price, volume, time, and space.

Retail investors generally focus on the price, but many professionals will put the volume in the first place, and OBV is the indicator of the volume.

According to 1 to 100, OBV plus or minus 1, representing the trading volume of the underlying stock plus or minus 100, trading volume plus or minus 200, Wanli Financial Research Institute often uses OBV to cooperate with other indicators, and some areas are often dyed red, so Yao Shuliang and these people call OBV a big aunt.

"The more the eldest aunt comes, the more red she becomes. Wang Nuo remembered the words of Yao Shuliang and other seniors, and smiled inexplicably, but he still put his thoughts on the selection target.

From Ma Lin's report, Wang Nuo can see that the views of the Shanghai University of Finance and Economics Research Institute on road and railway transportation also remain volatile.

Coupled with a lot of data and information, it is obvious that the stocks of the transportation industry will be biased towards maintaining a volatile pattern, which means that there is no chance, but OBV also has a small name called the catcher.

And although Wang Nuo can't know the direction and steps of the Blue Sky Fund's operation, he can see its position distribution like everyone else, and there is an article here.

"It seems that in addition to shipping, the Blue Sky Fund also holds a few stocks here in road and rail transportation. Wang Nuo opened the file and saw the status and analysis reports of several stocks held by Blue Sky Fund.

Finally, Wang Nuo focused his attention on the Shuchuan Expressway, a stock with a total market value of more than 20 billion yuan and a closing price of 12.64 yuan today.

The reason for choosing this is very simple, the analysis report of this stock was made by Wang Nuo and Yao Shuliang, and Zhou Minghai did not make any changes.

"The OBV change number of Shuchuan Expressway this week is between 1400 and 1600. Sitting on the chair, watching this sentence stay on the paper, and then looking at the OBV of -300 points in the first two days of the Shuchuan Expressway, Wang Nuo rubbed his forehead.

That said, it's likely that it's all down this week, and the market hasn't come yet. Wang Nuo was a little helpless.

The calculation of OBV, if it was 10,000 the day before and the trading volume is 30,000 hands today, but it is falling, then after today's closing, OBV is 9700, and if it is up, it is 10300.

The OBV indicator of Shuchuan Expressway has fluctuated for a while, from a technical point of view, it has the possibility of big changes at any time, Wang Nuo knows that the Blue Sky Fund holds a lot of stocks, and is very familiar with its analysis report, he originally had two plans.

If the OBV change data of Shuchuan Expressway this week is not around 1500, it means that after it fell in the first two days, it is likely that there will be some rebound in the next three days, if the speculation of the amplitude is about 1500, it is more likely to be a small shrinkage shock downward in the case of more than 600 in the first two days.

"If you don't make money in vain, you can't make money, but if you want to sell short, you have to borrow securities, I should ......" After determining the plan a little, Wang Nuo took a shower and fell asleep.

The next day, Wednesday.

After a little lazy sleep, it wasn't until almost nine o'clock that Wang Nuo arrived at the research institute, and when he saw him with two dark circles under his eyes, Zhou Minghai didn't blame him for being late, but counted him down a few words with some concern.

Compared with Wang Nuo, Yao Shuliang, who also has dark circles under his eyes, enjoys completely different treatment, he arrived earlier than Wang Nuo, but was severely reprimanded by Zhou Minghai.

"This is the so-called intergenerational parent. When Zhou Minghai returned to the office, Yao Shuliang said a little sour and shameless in everyone's ridicule: "Brother Hai is my master, I am Arnold's master, and my master always dotes on his apprentices, I understand." ”

"So, master, do me a favor. Wang Nuo came up.

"What's the matter with the apprentice?" Yao Shuliang was a little alert.

"Help me open margin financing qualifications for my funding account. Wang Nuo scratched his head.

"Fuck off, I don't want to be pressed to the ground and rubbed by Brother Hai. Yao Shuliang was taken aback, and didn't dare to agree to this matter at all, "Arnold, don't be crazy, you still want to finance and lend securities with that little money, do you want to go to heaven? There is no such contract in the industry." ”

Thanks to Yao Shuliang's guarantee, Wang Nuo's allocation leverage is 1 to 10, and then he is qualified for margin financing and securities lending, doesn't it mean that he can use a maximum amount of nearly 20 times, and if it falls by 5%, he will directly lose the principal.

Yao Shuliang really wanted Wang Nuo's good, of course he didn't want to agree to this matter, he had a way to give face to the capital allocation company that didn't open margin financing and securities lending, but he didn't want to do it, the risk was too high.

Wang Nuo knew that Yao Shuliang would not agree, but he also guessed that Yao Shuliang would help in another way.

"Do you want financing or securities lending, and how long will it take?" Yao Shuliang really rolled his eyes and asked.

"Securities lending, at most two or three days. Wang Nuo blinked, if he didn't know how to sell cuteness, he would definitely have to sell cuteness to Yao Shuliang.

Unexpectedly, Yao Shuliang immediately took care of the whole package and said: "Use my account, you also know, Brother Liang, I have recently cleared my position, and I will definitely wait and see this week, and the money will not be used in vain." ”

"Thank you, master. Wang Nuo agreed without the slightest hesitation, so that Yao Shuliang obviously realized that he was calculated, and immediately "angry", and after a good "reprimand", he pretended to say that he had nicknames such as Tuhao Liang and Shi Yu.

Under Yao Shuliang's questioning, Wang Nuo had no intention of concealing it, and even handed over the operation to the other party, just asking to sell the Shuchuan Expressway as short as possible.

This is actually a harmless calculation, if Wang Nuo is allowed to operate it himself, the amount of securities lending is not appropriate, if it is only required to try to hand over the amount to the "local tyrant Liang" to decide, then Yao Shuliang will definitely not be stingy.

Yao Shuliang knew that Wang Nuo had nearly 100,000 yuan in his account, and he was very aware of the market of Shuchuan Expressway, so he helped Wang Nuo look at the market by himself, and slowly used up all the more than 800,000 yuan in the account, and then asked Wang Nuo to add one more to the number of times he agreed to treat.

The daily trading volume of Shuchuan Expressway is now swaying above 30,000 hands, according to the price of more than 1,200 yuan per hand, Yao Shuliang helped Wang Nuo to borrow 659 hands, in order to raise the price to 12.62, he was busy until noon.

Since Wang Nuo's previous operations were very smooth, this time he entered again, and the group of people in the research institute, such as Lu Chang and Chen Man, were very concerned, and even had a willingness to follow the operation.

People who speculate in stocks believe in luck very much, and Wang Nuo's luck is undoubtedly very good.

On Wednesday, the volume of Shuchuan Expressway shrank and fell, closing at 12.51, down exactly 1%, and OBV lost more than 300 yuan.

The next day, April 19th, Thursday, just opened, Shuchuan Expressway did not surprise everyone at all, and then shrank and fluctuated, but unlike some time ago, at the price of 12.5, it was very strong.

If this important support level is broken, there is a danger of flooding on the Shuchuan Expressway, but if the eldest aunt OBV comes, the situation will be very complicated.

Wang Nuo knows that this week's OBV will be added or subtracted by 1500 to 1600, and in the case of almost 1,000 reductions in the first three days, it is very likely that it will shrink today, after all, the stock price has fallen, and the eldest aunt OBV does not need to be a guest.

However, the OBV data of the Shuchuan Expressway was completely unexpected by Wang Nuo, it broke out, and the eldest aunt came.
