How to control the position of digital currency contract

1.

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

2. The premise is to choose the right stock, position according to the trend, price to set. I'm usually a fifth.

3. This kind of thing is of course your own control, do not suoha, look at the market is not right, stop profit and stop loss in time, learn more books.

4. 1. Why control the position? From a negative point of view, it is to control the total amount of risk, especially to control accidents. Even if you look at the right market direction and choose a better position, there will always be small probability accidents in the market. For example, one or two stops will suddenly reverse, and then the trend will recover. I have encountered such things many times in recent years. Fortunately, the position is well controlled, No matter how many times you succeed, an accident will cost you 10 years. In the field of venture capital, you must stare at the 5% fatal accidents, If you can't control your position, no matter how well you do, it doesn't make sense, And you can expand profits. If you do the middle line, once you do it right, you can increase your position by decreasing every time you conquer a resistance level. You can make your position when you make a profit always greater than that when you make a mistake. 2. How to control your position? I think the following points must be adhered to: first, the total position should not be more than 50%; Second, the position of each variety should not be more than 30%; Third, the positions are scattered on unrelated varieties; Fourth, build warehouse in batches; Fifthly, never increase the position on the loss position; Sixth, only when the new resistance level breaks through and is confirmed, can we add positions; Seventh, the increase of warehouse should be carried out in a decreasing way; 8. Don't add positions more than twice. Controlling the profit and loss rate of positions is another key to the success of futures trading. The first is the problem of stop loss. Those who don't know the stop loss will be eliminated of course, but those who know the stop loss will also be eliminated, because stop loss means making mistakes. If you keep making mistakes, what else will not be eliminated? Therefore, the core problem is not that you know the stop loss, but that you should try to avoid the ending of the stop loss. You must put the stop loss into all your trading strategies. First, you should strive to make the success rate of the opportunity you seize more than 50%, and choose a more favorable position to build a position in the trend process; In other words, if you trade ten times, you'd better end up with a stop loss of less than five times; Second, your position should not be too large, because if you have too large a position, even if you only meet one stop loss in ten trades, you may lose completely; Third, you should ensure that your stop loss position is less than your success position, otherwise it will lead to more stop loss and less profit; I don't understand short-term trading. From the perspective of medium and long-term trading, I feel that stop loss can only be made when it is really wrong, or when I don't know whether it is right or wrong, because the establishment of middle line positions is based on trend + withdrawal or turning + confirmation. Therefore, stop loss should be made when the trend is destroyed or the turning is unsuccessful; But there is also a problem of capital bearing capacity. My experience is: the loss position is based on the trend line / neck line / moving average, plus the absolute stop loss amount of about 5% of the total capital. As my single proct position is only less than 30%, and I try to build a position when withdrawing, the stop loss environment is relatively loose, which can resist the general shock; Fifth, if the stop loss is wrong, we should build back the lost position in time; Sixth, we must stop loss when we encounter false breakthrough; Seventh, in the formation of the form, we only build the position in the original direction, increase the position when the form breaks through, and break through the stop loss and backhand when the form breaks through

5. Hello, when making an order, you should make an order according to one third of the position, and then increase or decrease the position according to the change of the market. Hope to adopt!

7. There are three forms of trend: upward trend, downward trend and horizontal trend. The most tangled should be the horizontal arrangement
at this time, we can actually look for indivial stocks with a large range of top and bottom volatility, and cooperate with channel indicators to do short-term high selling and low absorbing. We don't have a fluke mentality, and we can take it when it's good. There are still opportunities to make a little money. I used the "three three system" method to control the warehouse, which won the short-term speculation and the overall market
the so-called "three three system" position control method is to control the position according to the trend. When you don't know whether you are going up or down, you can only hold 1 / 3 of the position in the shock or early adjustment. If the stock continues to be bullish, as long as the increase is more than 4%, we should consider making up 2 / 3 of the position. If the increase is more than 8%, we can hold the full position. Once the stocks held by full positions rise by more than 20%, the conservative approach is to close them when they are good and sell them all. If the full position falls sharply before it is bullish, with a decrease of more than 4%, the position will be immediately reced by 1 / 3, which is the part that has made profits. If the decline is more than 8%, you can rece your position by another 1 / 3. This part is equal to the flat part, no loss, no profit. This is equivalent to free up 2 / 3 of the funds, you can wait for the opportunity to fill positions. If the position of 1 / 3 of the stock falls by more than 4%, you can make up 1 / 3 of the position, which is used to spread the 1 / 3 of the stocks covered. At this time, if you have been in the doldrums, you will generally keep 2 / 3 of your position. In case of sharp rise and fall, you can leave your position in time when it is high, and make up for it when it is low

the following two points should be paid attention to when using this method:
1. Seize a few stocks that you have long been concerned about and optimistic about. These stocks will be selected as optional stocks, while other stocks, whether recommended by institutions or stock reviews, should be cautious and not easily followed

2. When the decline is more than 15%, we must cut the position and cut the flesh to get into the strong stocks in the market. We should also use the "three three system" method to buy new stocks to offset the losses of the former with profits. Of course, if the market falls at this time, has been in the doldrums, short wait is the safest way
3
the market is in the consolidation period, so it is good to adopt the "three three system" to control the position. I think that every time 1 / 3 of the warehouse weight can be replaced by 1 / 4, 1 / 5, flexible use of this method can achieve certain results.

8. There is a position horsepower table in my stock trading software. I usually make a position strategy according to my actual situation. I use Yimeng operator Qiankun version. As for other software, I don't know.

9. Position control:
position control, investment term. Simply assume a model, a straight trading cycle is 3-5 trading days, the risk and profit expectations are within 10%,
the approximate proportion of positions is set at US $20000 1 standard hand or US $2000 0.1 standard hand, that is to say, the loss and profit expectations are within 200 points

the position control should be as follows:
1. When the market rises steadily, keep 70% of the position. When the stocks in hand are profitable, increase the position and hold the full position
if the stocks bought later are jacketed, you can sell some of the stocks that have made a profit, free up funds to cover the position, spread down the cost of the jacketed stocks, and make them unwind as soon as possible
Second, the market is in the box shock or the early stage of adjustment, maintaining 40% to 60% of the position, timely losing weight when the stock in hand is high, decisively buying when it falls sharply, closing when it gains, fast in and fast out
Third, when the market is in a downturn, don't take chances, cut the flesh with pain, and wait for the opportunity
investors should be reminded that full positions are not recommended at any time
in addition, adjusting the position structure is also a way to control the position. Investors can sell some stocks that are not active, have a large plate, lack of subject matter and imagination space at high prices, and choose some stocks that have Xinzhuang's position and are likely to evolve into mainstream and leaders in the future

10. Of course not. There's a saying in the contract that a full warehouse will die! 58coin exchange reminds investors that nothing is absolute, and even the fund can not completely control the impact of emergencies and policies or news. The accumulation of wealth is proportional to time, which is the consensus of masters at home and abroad. It is hoped that small funds can make profits in large bands. The large fluctuation of capital curve itself is an abnormal phenomenon. The only way to success is to advance, retreat and steadily pull up.
