3. You can search for POBO or China financial investment decision-making software on Thunder. I think POBO is better! Changjiang securities Futures Investment Software Recommended!

4. Option pricing model, I don't know if you can understand it, but after careful study and careful decomposition, you should be able to understand it:

C=S？ N(D 1)-L？ E-γT？ North D2

These include:

D 1= 1NSL+(γ+σ22)Tσ？ T

D2=D 1-σ？ T

C- initial reasonable price of option

L- option delivery price

S- the current price of the financial assets traded.

T- period of validity of option

R- risk-free interest rate h of continuous compound interest.

σ2- annualized variance

N()- cumulative probability distribution function of normally distributed variables, here are two points to explain:

Make the following supplement to your answer!

1. Why can I only buy (partial) stocks when buying futures?

Because mock websites have rules! Some are that you can only use the percentage of all the assets he gave you, which is stipulated by them, so you can only buy a part, that is, shares!

2. Why is the system set at 25,000 yuan each, and you can only buy 10!

Because the problem lies in the quota of 25,000 lots set by the system, that is to say, you can't buy more than 25,000 lots of each futures product! Then you can only buy 10 lots, which means that the unit price of futures you buy must be above 2272 lots! So you can only buy 10 lots, which is the unit of 10 you said, and this is the restricted operation of the simulation system for you!
