Zhang Heng looked at the curve of the rebar.

Exactly as predicted by the simulation.

The market is closed!

A ton of rebar has increased by dozens of yuan!

This is only an increase of a few points.

The results of the simulator have already shown that after 10:30 tomorrow, the market will start to skyrocket.

By the time.

Certainly not such a low increase of a few o'clock.

At that time, you can earn thousands of dollars with one hand!

And the same money.

Put it in the stock market.

Even with a daily limit, you can only earn a few tens of dollars per hand.

Hundreds of times the income difference!

No wonder so many people have to enter the futures market one after another.

Some people feel that they have mastered the essence of futures after learning a little on the Internet, and step into the futures market with confidence.

result.

They all threw their hard-earned money into the abyss, expecting the devil to give ten times the return.

in the end.

His wife and children were separated, and his family was destroyed.

Debt collectors come every day, even cutting the waist is not unheard of!

Lost money, lost people.

at last.

When I jumped off the building, I didn't even wear pants!

Everyone knows that it is necessary to treat every fluctuation of the market with a normal mind, and avoid greed and panic.

But.

It's the same as smoking.

Everyone knows that smoking is harmful to health.

But there are still so many people smoking.

Zhang Heng put down his phone.

Take a long breath.

He knew that without a simulator, he would not have stepped into the futures market.

Ordinary people, a lot of information is simply impossible to know.

By the time you know it, the market has passed. Biqu library

Wu Na was almost falling asleep.

Seeing Zhang Heng finally put down the phone, she immediately regained her spirits.

"Zhang Heng, are you done?"

"These curves are crooked, what's so good about them? They're not as good-looking as conic curves and hyperbolas! It's even better to exercise people's imagination!"

Zhang Heng nodded, hummed, and said:

"Where is the imagination trained like this?"

After a few seconds.

He suddenly came back to his senses.

Take a deep breath.

He lowered his head and looked at Keren lying in his arms, showing a look of shock.

Zhang Heng: "..."

"(她c哦)!"

turn out to be.

Is that how imagination works?

I have learned mathematics for so many years, and it was all for nothing?

Conic section?

hyperbola?

In Zhang Heng's mind

, a graph of the two curves emerges.

Compare it with the one in front of you.

really!

Immediately, he said something in his heart!

After studying mathematics for so many years, I didn't realize this!

Mistake mistake!

Shame on fellow men!

Wu Na raised her small face, looked at Zhang Heng's shocked face, and burst out laughing.

"what's wrong?"

"Looking at you, don't you know the real secret of conic curves and hyperbolas? Let me tell you, these two curves are the goals of our girls!"

"There are so many mathematical functions, and most girls learn these two functions best. If you don't believe me, you can ask them!"

Zhang Heng looked at Wu Na in bewilderment.

A burst of shame!

Sure enough, there is a big difference between the boy's world and the girl's world.

He reaches out.

Caught it.

After looking at the range again, he said:

"You are... the standard equation of y2=2px (p>0)!"

Wu Na understood immediately.

laughed and scolded:

"Hate!"

Zhang Heng threw the phone away.

Get up.

"Tonight, let me review my previous mathematics knowledge carefully. Some knowledge points need to be supplemented, or I will forget them all!"

then.

for the rest of the time.

Zhang Heng and Wu Na devoted themselves to studying and reviewing conic sections and hyperbolas.

This review is a whole night!

 …

the next day.

Zhang Heng woke up in the afterimage of curves in his eyes.

Reach out and touch.

around.

The hyperbola is gone, only a single coordinate axis remains.

and.

The ordinate is still with him.

outside the room.

Wu Na's voice came.

"Are you awake? Hurry up and have breakfast, hot milk and fried eggs, you need to make up for the lost nutrition! Otherwise, you won't be able to make ends meet!"

Zhang Heng: "!!"

The gods can't make ends meet!

This little girl, when no one else is around, really let go!

Zhang Heng got up in a hurry.

When he got dressed and came out, there was already a freshly prepared breakfast on the table.

A large cup of steaming milk, he took a look, no less than 500ml!

Zhang Heng is ashamed!

This girl, how many times do you want to mend it yourself?

Next to the milk, on a plate, there are three fried eggs just out of the pan, sizzling, and there is the sound of frying.

Zhang Heng

A face of black lines.

In addition to protein, do you not need anything else?

at this time.

Wu Na is wearing a small apron.

Came out of the kitchen.

Seeing that Zhang Heng hadn't moved her chopsticks, she hurriedly urged:

"Hurry up and eat while it's hot."

"When it gets cold, the taste will change."

talking.

Wu Na sat down herself.

Zhang Heng looked over.

in front of her.

It's a fried egg, and a glass of freshly squeezed vegetable juice, and nothing else.

Zhang Heng said with a bitter face:

"Vitamins, do I need to add some?"

Wu Na tilted her head, looked at Zhang Heng, and said puzzledly:

"What you consume is a lot of protein. Why do you supplement with vitamins? What is missing is what you need to supplement. Is this the truth?"

Zhang Heng: "..."

I actually! Speechless!

It makes sense!

His stomach was already growling, so Zhang Heng picked up his chopsticks and started to eat.

After eating hot milk and hot fried eggs, I immediately felt my whole body was full of strength, and I could fight him for another 300 rounds without any problem!

finish breakfast.

Zhang Heng took out his phone and looked at it.

It's getting late.

Today is January 28th, Friday, the last working day of this week.

If he wants to open an account, it must be today.

Otherwise, we can only wait until the next year.

A futures account needs to be opened.

You can open an account between 8:40 and 17:30 on the trading day.

It is very convenient to open an account now. You can open an account online on your mobile phone with your ID card ready, and you don’t need to go to the business hall to handle it.

Of course.

If you want to open a stock index and crude oil futures account, you can't open it on your mobile phone, but you have to do it at the counter.

What Zhang Heng wants to open now is only commodity futures and metal futures.

so.

A mobile phone will do.

It was already 8:30 in the morning.

Wu Na is clearing the dining table.

Holding his mobile phone, Zhang Heng took out his ID card, bank card and white paper signed photo from his pocket, went to the living room and sat down, ready to open an account.

He had already called Xiao Qinxin in advance and asked her to be his introducer.

Time is up.

Zhang Heng opened the Xiwu Futures app that he had downloaded a long time ago, filled in the information according to the prompts, and chose the Zhengzhou Stock Exchange, the Big Stock Exchange, the Shanghai Stock Exchange, and ordinary investors...
