What to consider when making a live trading system

As a large-scale real-time trading system, customers have put forward very high demands on the system, and their needs are mainly focused on the following three points:

1) Real-time: The transaction system is a system with very frequent business processing and large data exchange throughput, and the speed of business processing is directly related to the company's economic benefits and customers' evaluation of the company. Under objective conditions, the entire WAN system must maintain rapid real-time response capability while maintaining large traffic to ensure the smooth operation of the entire business system.

2) Security: The security issue is mainly reflected in the security of the trading members' funds and transactions and the security of the internal network of the business department, but with the establishment of the company-level WAN system, especially in the local currency trading system, the security of the system is more important, and the security of the entire system is fully considered in all aspects. In addition, all important operations in the system must be absolutely traced to standardize management.

3) Reliability and robustness: Customers require continuous and trouble-free trading in the process of system trading, because once the transaction is interrupted, it will bring losses to the trading members. The system checks the correctness of the user's sequence of operations, the data entered, and displays error messages in a conspicuous manner.

The system error handling mechanism must be used, and when an error occurs during the operation of the application software system, the system will clearly prompt the error message and guide the user to deal with it. It provides the operation monitoring and fault recovery mechanism of the system, generates log information of the system operation, and tracks all the operations of the system, so as to facilitate the immediate detection and troubleshooting.

Through the acquisition of system characteristics, it can be seen that every large-scale real-time system has its common requirements, such as real-time requirements, reliability and robustness requirements. However, due to the particularity of the local currency trading system, customers also put forward high requirements for the security of the system. From this point, it can be seen that when obtaining the requirements of the system, it is not only necessary to grasp the common requirements, but more importantly, to explore the hidden requirements, which may often be ignored by the requirements analyst or the customer, but are very important.

Relatively speaking, this step is the easiest, because the change is simplified into two directions. If you go in one wrong direction, you will go in the opposite direction. Some people think that there are three directions, in addition to ups and downs, there are also sideways.

But the flat is only relative and temporary. Only the ups and downs are absolute and eternal. The problems caused by sideways trading can be solved by timing and money management.

Timing Timing and money management are inextricably linked. To understand the timing decision is to understand that the market is essentially an opportunity market. The success of speculation depends largely on your ability to judge opportunities.

The stronger this ability, the less frequent the trades. Many investors tend to "use all the tricks and attack all the way", like headless flies scurrying around, going in and out several times a day. Masters will never take an easy move before the opportunity comes, and once they find an opportunity, they will make a move.

Opportunities in trading occur only at the moment when the long-short balance is broken, i.e. the "tipping point" in the chart. A good timing decision can be done: First, the entry and exit points are very clear, the stop loss point is not only easy to find, but also the stop loss range is very small, and the order eaten at this price is easy to handle.

The second is that if this transaction fails, the next step should be very clear, that is, what to do after the stop loss is out should be easy to choose. A good time is the time when you can attack when you can attack, and when you can defend when you retreat. Money Management Money management is the question of how much to do.

In actual trading, the single volume control is to achieve two effects: to make a large profit when you do it right in trading, and to lose a small amount of money when you make a mistake. To do this, you need to have a good timing to make a decision, and set the *** and take profit levels strictly.

At the same time, it is necessary to pay attention to two aspects: first, insist on using pyramid increase in trading; Second, it is necessary to properly deal with the choice of whether the order volume should be increased or decreased after successive profits and losses. A master is always able to make the profit of a correct trade cover the loss of multiple mistakes; Weak hands tend to eat up the profits of multiple correct trades with a single mistaken loss.

Mind Control The ability of an individual to control their mind is important. In fact, the quality of the mentality is related to the personality and experience, with the enrichment of experience, the psychological control ability will gradually strengthen, but once it comes to the personality reasons, it is not possible to solve the problem by experience. Many times, trading requires guts, such as when facing a breakthrough after a long period of consolidation, it is best to keep increasing the order volume when there are continuous errors.

However, few people have the courage to increase the order volume when there are continuous mistakes in actual trading, because this requires a strong psychological tolerance. The vast majority of traders will unconsciously reduce the size of their orders when they make mistakes.

Trading rules, money management, and psychological quality are the 3 elements of the system. The classic view is that among the three, psychological quality is the most important, accounting for 60; The second is money management, which is also very important, accounting for 30; Finally, and least importantly, there are systematic trading rules, which account for 10

A system is a group of connected individuals who work according to pre-programmed rules, and can do the work that individual elements cannot do alone. A trading system is an integrated software or platform suitable for the management or execution of buy and sell transactions, which is a combination of multiple single functions that are pre-programmed. As****.

The trading system is the materialization of systematic trading thinking. Systematic trading thinking is a concept, which is embodied in the overall observation and continuous observation of the movement in the judgment analysis, and the comprehensive embodiment and adoption of the three elements of the transaction object, the transaction capital and the transaction investor in the decision-making characteristics.

To put it simply, a trading system is a system of trading rules with complete buying and selling signals.

There are several problems to be solved in this system: 1. When to buy; 2. What to buy; 3. What is the proportion of positions; 4. When to stop loss; 5. When to play.

The trading system will make people's investment behavior more objective and rational.

To put it simply, it is your best technique, habits, and ways.

A complete trading system consists of two main categories: entry strategies and exit strategies, and then it is necessary to ensure the strict and effective execution of the trading system.

A complete trading system must be both offensive and defensive. Catch opportunities when they arise and reduce them when they arise**.

1 is the first part, you can see the trend of the related market varieties you need, and you need to see the general trend when using arbitrage hedging.

2 is fundamentals, as much real data as possible, not stock reviews and recommendations. It includes both corporate and economic fundamentals.

3 statistics of exchange transactions, gambling with others, at least to know who is on the table, how much silver, don't know anything, dare to go into the water is looking for death.

4. Complete transaction channels to ensure that the distribution of accounts is reasonable and timely transactions are smooth.

What is a trading system? A trading system's judgment on the finger is objective.

The trading system can be understood as a set of operational guidance that includes the sum of a series of rules such as variety selection, ** size, opening positions, adding and reducing positions, closing positions, and capital management.

The content contains the entire trading logic of the trader and appears in the form of specific execution.

Through the fixed rule, each order in the trading order becomes a sample of the entire probability event, so that the logical probability advantage can be brought into play.

A trading system is a set of rules that can achieve stable profits in the market. It includes scientific money management, effective analytical techniques, and good risk control. Its ultimate goal is to achieve or vertical stable profits for traders.

It can be divided into subjective trading systems, objective trading systems, and trading systems that combine both. A trading system is the brainchild of a trader, and it embodies the trading philosophy of a trader. Therefore it does not have.

Universality, i.e. a trading system can only be most effective in the hands of its creator. Therefore, for traders, only by creating their own trading system can they embark on the road of stable profit profit.

The importance of the trading system is now more and more concerned by investors, with the development of China's first market, investors from the original blind trading is gradually turning to rational investment, from the passive to follow the market to the trading system to guide their own trading. Judging from the fact that there are some people in the market who make long-term profits, a long-term profitable trading system should exist, but the trading system is just a trading tool for trading, and not everyone will get the same trading results with a trading system. Obtaining a trading system and making a profit through a trading system are not the same thing at all, the ability to use the trading system is far more important than the trading system itself, just like the key to determining the outcome of a war is people rather than **.

I think that judging a trading system should include at least the following aspects: 1. Whether there is a clear trading signal 2, whether the risk can be effectively controlled 3, whether it is operable 4, whether it has profitability, rather than the number of profits is greater than the number of losses 5, whether it is suitable for yourself.

It is not difficult to find or buy a trading system now, the trading system itself is not a secret, you can have one or even several trading systems if you want, but how to make a profit is still a real secret. For most investors, there is not much difference between trading with a trading system and the trading results they have explored, and long-term profits are still out of reach. He will find that the system works well in demo trading, but it doesn't seem to work so well once it is in practice.

The reason for this is that the investor may not really understand the trading system, or the trading system is not suitable for him, and the key factor may be that the investor does not have the ability to use the trading system at all, and he cannot digest and absorb the trading system.

If you want to make a profit through the trading system, you must first have a correct understanding of the trading system, and at the same time, your trading ability must match the trading system. Don't try to get a three-year-old to fly a space shuttle, and don't think that a three-year-old is useless just because he can't fly a space shuttle. In fact, most investors are like a three-year-old child in front of the market, but their desire to make profits is the same as that of adults, which leads to a high level of trading.

When you recommend a proven trading system to him, like a three-year-old recommending a space shuttle, he is excited and willing to accept it, but that doesn't improve his trading. Again: the ability to use the trading system is far more important than the trading system itself!
