In the futures, stock trading, because the directions in the wrong position and the stop cut is quite normal, but many people clearly go against the direction of, and are often due to excessive opening the granary can not afford the price of capital caused by repeated forced to cut positions, This is a very unjust. To avoid this situation, it should be from the beginning to enter a position based on risk control requirements, unlocked the cells and limit the amount of a reasonable scope, and this is a risk control system, the first step in the transaction. However, this step should be how to get it?
Transactions in the system under the premise of opening the granary is proportional to the amount and risk (of course, and earnings are also proportional to). Under the premise of setting stop-loss, risk control mainly through unlocked the cells and the amount of control, control of the unlocked the cells and thus control the amount of risk.
To futures trading, for example, in the Jiancang opening the granary for calculating a reasonable amount of data required is as follows:
The total investment, opening the granary price, stop-loss price, risk-control rate.
No explanation is needed before the number of data, mainly to explain what is meant by risk-control rate.
Risk control rate = total amount of investment to allow the loss amounted to ÷ × 100%
To risk investment in terms of trade, science and psychology of investment should be in every transaction there is a loss should be prepared for a loss of how to prepare, is a relative ratio of the number of investment capital is a relatively stable indicator of the formula should be used to said. So much for setting the rate of risk control is good? Certainly can not be 100%, if it is a loss of 100% of the investment put all Kuidiao, and it can not be emancipated, then 50% can not? If your trading system or trading system, there is no possibility of mistakes in a row, you should ensure that the number of loss intervals not too close, and, in case you lost, you even with 50% of the surplus capital could soon be put Principal re-Zhenghui Lai, rather than a loss encountered, otherwise the set of risk control rate of 50% is larger. From the above analysis shows that the rate of risk control settings have a scientific method to calculate this calculation should be based on their own to determine the level of transactions. From another point of view, risk control rate is still a subjective indicators established under the premise of the scientific, investors are also characteristics of their own choice of the conditions of human nature, for example, aggressive type of investment were obviously than conservative investors who prefer a more high-risk control rate. With regard to the formulation of risk-control rate to explain briefly here so much, then, I will be at an appropriate opportunity to give a thematic analysis.
The following is the reasonable and unlocked the cells and the amount calculated as follows:
(Risk Control) unlocked the cells and the amount of = to allow the loss of investment capital amount ÷ hand unlocked the cells and the expected amount of loss for each
Of which: to allow the loss of investment funds, investment funds, the total amount of = × risk-control rate
Each hand unlocked the cells and the amount of expected losses = | unlocked the cells and Price - Stop Price | × for each standard size of lots
For example: at 9:28:12 on June 28, 2002 Dapeng trading system signals, soybeans, September tendency to rise, the system purchase price of the signal unlocked the cells and 2086 yuan / ton, stop-loss price is 2062 yuan / ton and soybean futures standard contract capacity of 10 tons / hand, the existing total capital of 500,000 yuan, risk control rate of 5%, please ask for public assistance calculating the amount of risk control.
Solution:
Allowed amount of the loss of investment funds
= Total amount of investment funds rate × Risk Control
= 500,000 yuan × 5%
= 25,000 Yuan
Each hand unlocked the cells and the amount of expected loss
= | Unlocked the cells and Price - Stop Price | × for each standard size of lots
= | 2086-2062 | × 10
= 240 Yuan / Hand
(Risk Control) unlocked the cells and the amount of
= Amount of investment funds to allow the loss of ÷ hand unlocked the cells and the expected amount of loss for each
÷ 240 = 25,000 Yuan RMB / Hand
�104 Hand
�104 Hand × 2086 dollars (the amount guaranteed for each hand) "500,000 yuan
�the decision-making instruction: According to the terms of 2086 yuan to buy unlocked the cells and September soybean futures 104 hands.
In accordance with the above method to calculate the amount of opening the granary, not only the fluctuations in the future if the loss is not greater than 5% of the intended level of control, even if the actual losses in the future there will also be within a predetermined level of control.
