Will contracts affect the market situation? Digital currency

1. 1. digital currency contract, also known as futures contract. In short, it's business in the future. A standardized contract uniformly formulated by the exchange to deliver a certain quantity and quality at a specific time and place in the future. The vast majority of users use the margin system of futures contracts, add 10 or even 20 times leverage to leverage big funds, and then use the index fluctuation to buy low and sell high trading contracts, so as to earn double profits< 2. Perpetual contracts are derivatives. From the perspective of trading, it is similar to the traditional futures contract, but there are some differences. First of all, it has no maturity or settlement date. The perpetual swap contract is similar to a margin spot market, so its trading price is close to the underlying reference index price, which is different from the futures contract. Due to the basis, the trading price difference of the futures contract may be significantly different. Secondly, the main mechanism of anchoring spot price is capital cost< At present, rolling spot futures is the main form of perpetual contracts. Rolling contract is a kind of futures contract settled on the same day and automatically extended. Profit and loss are settled on each trading day, and the contract position held by traders will be automatically extended at the end of the trading day. In addition, the cash flow of assets will be exchanged, and the long investors will pay the capital cost to the short investors to compensate the capital cost of the short investors
3. Option contract is a kind of agreement, which can give traders the right to buy or sell assets at a predetermined price before a specific date or on a specific date. Option contracts are trading derivatives that can be based on a wide range of underlying assets, including stocks and cryptocurrencies. These contracts may also come from information such as financial indicators. Generally, option contracts are used to hedge the risk of existing positions and speculative transactions.

The contract transaction of digital currency is not safe. There are still many loopholes in the digital currency trading platform, for example, the most common are the following six kinds:

1. Denial of service attack

denial of service attack is the most important attack against the digital currency trading platform at present. Through denial of service attack, the attacker makes the trading platform unable to access normally, Because users can not accurately distinguish the degree of attack, it often causes panic asset transfer, which brings some loss

2. Phishing incident

even the best technical measures at present can not make the digital currency trading platform avoid phishing attacks. Some hackers and criminals can confuse digital currency investors by means of fake domain names or fake pages, while ordinary investors can't identify the authenticity, so it's easy to cause asset losses

Many digital currency trading platforms use a single private key to protect the hot wallet. If hackers can access a single private key, they can crack the hot wallet related to the private key. For example, in the attack on yapizon of Seoul stock exchange in 2017, the attackers stole hot wallets from the trading platform twice in a year, resulting in a total loss of nearly 50% of the assets of the trading platform and eventually leading to the bankruptcy of the trading platform

Fourth, e to the lack of perfect risk isolation measures, or ineffective supervision on the rights of employees, some employees who have the operation rights of the platform use internal trust to seek unjust wealth for themselves. For example, in 2016, the event of employees stealing bitcoin on shapeshift caused a total loss of US $230000 to the trading platform by stealing and reselling sensitive information to others

Fifth, the software vulnerability of digital currency trading platform includes single sign on vulnerability, OAuth protocol vulnerability and so on. At present, all countries have laws requiring banks or other financial institutions to implement information security measures to protect customers' deposits. However, e to the fact that the blockchain field is still in its infancy, there is a lack of such specifications for encrypting digital assets. Therefore, it is not accidental that many trading platforms have a large number of loopholes in the absence of security constraints

6. Transaction malleability the technical supporters of blockchain often think that blockchain transactions are highly secure because they are recorded on records that are said to be unchangeable, but each transaction needs to have a corresponding signature, and the records can be forged temporarily before the final confirmation of the transaction

rules of contract transaction

1. Transaction time

contract transaction is 7 * 24 hours transaction, which will be interrupted only ring the settlement or delivery period of 16:00 (UTC + 8) every Friday. In the last 10 minutes before delivery, the contract can only be closed, not opened

Transaction types are divided into two types, opening and closing. Opening and closing positions are divided into two directions: buying and selling:

buying open long (bullish) refers to buying a certain number of contracts when users are bullish and bullish on the index. Carry out "buy open more" operation, match success will increase long position

selling pingo (multi order closing) refers to the selling contract that the user makes up for when he is no longer bullish on the future index, offsets with the current buying contract and exits the market. Carry on "sell flat much" operation, match after success, will rece long position

short selling (bearish) refers to the new sale of a certain number of certain contracts when the user is short or bearish on the index. Carry out the operation of "sell short" and increase the short position after successful matching

buy close (short single close) refers to the buy contract that the user will not be bearish on the future index market and make up for, offset with the current sell contract and exit the market. Carry out "buy short" operation, after matching successfully, short position will be reced

3. Order method

limit order: the user needs to specify the price and quantity of the order. Limit order can be used for opening and closing positions

order at opposite price: if you choose to order at opposite price, you can only enter the order quantity, not the order price. The system will read the latest competitor price at the moment of receiving the entrustment (if the user buys, the competitor price is the selling price of 1); If it is a sell, then the counter price is buy 1 price). Issue a price limit order for this counter price

4. Position

the user owns the position after opening and trading, and the positions in the same direction of the same contract will be merged. In a contract account, there can only be 6 positions at most, that is, multiple positions of current week contract, short positions of current week contract, multiple positions of next week contract, short positions of next week contract, multiple positions of quarterly contract and short positions of quarterly contract

5. Order restriction

the platform will restrict the number of single user's positions in a certain period of contract and the number of single open / close positions, so as to prevent users from manipulating the market

when the number of positions or entrustments of users is too large, the platform has the right to require users to take risk control measures, including but not limited to cancellation of orders, closing positions, etc. The platform has the right to adopt measures including but not limited to limiting the total number of positions, limiting the total number of consignments, limiting the opening of positions, withdrawing orders, forcibly closing positions, etc. for risk control

3. For many people, the concept of digital currency is a mystery. But there is no doubt that digital currency is different from virtual currency. Virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency. In 2013, the central bank, together with five ministries and commissions, issued the notice on prevention of bitcoin risks, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, which do not exist in the form of currency and legal currency. At the same time, digital money is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes.

6. Because this is a game played by swindlers and leeks. At present, the country's digital currency has not been released at all. All the digital currencies on the Internet are fraud!

7. The relationship between the stock index futures and the market index is complementary... The impact must be, as for the size, it depends on the position... For example: the bull market top in June 2015... The market has been obviously weak, just short of the last straw to fall... At this time, the stock market futures lightly touched, the index and indivial stocks desperately fell down... At this time, the influence is the strongest. At this time, we should pay close attention to the trend of stock index futures
similarly, in other times (volatile market), it also has an impact.. but the impact cycle is very small, and there are often inconsistencies between the stock index futures and the market index. At this time, the impact of stock index futures on the market index can be ignored
back to the issue of stocks, there are more than 3000 stocks, some of which are highly consistent with the trend of the market, and some of which are indifferent to the market. The specific operation is mainly indivial stocks
compared with stock index futures, we should pay more attention to the rhythm of plate rotation and the position of indivial stocks in the plate.

8. Whether the purchase of stock index futures will affect the market index, in fact, is mainly to study the relationship between stock index futures and the market index

the relationship between stock index futures and market index:
1. Stock index futures is actually a kind of futures, and its target is market index. The introction of stock index futures provides a hedging mechanism for the stock market. Its biggest function is to make hedging bilateral
2. Generally speaking, when the market goes up, the stock index futures will go up, and when the market goes down, the stock index futures will go down. On the other hand, we can also think that if stock index futures go up, the market will go up, and if stock index futures go down, the market will go down. If we are based on the market, it is helpful for us to study the short-term trend of the market by studying the trend of the main contracts of stock index futures and inferring the attitude of the main funds towards the future market
3. For futures investors, the investment of stock index futures is closely related to the market index. Timely attention to the trend and dynamics of the market index will be a required course for stock index futures investors every day

figurative metaphor: the stock market index is equivalent to football, while the stock index futures is equivalent to a bet (gambling ball) on the outcome of a football match.
