The application of different indicators is different. For people who speculate in stocks, of course, it is necessary to understand the significance of different indicators. The change of stock price is inseparable from the change of trading volume. The following is a collection of how to set the obv index parameters. Welcome everyone to come for reference.
How to set the obv exponent parameter
Obv energy tide index estimates the trend of stock price by counting the trend of trading volume, and quantifies the trading volume to make it a trend line. Use the trend line of stock price to estimate the market atmosphere from the relationship between price change and trading volume increase and decrease. Its main theoretical basis is that the change of market price must be coordinated with trading volume, and the fluctuation of stock price is closely related to the expansion or contraction of trading volume.
OBV index is a technical index to find active stocks and analyze the trend of stock price movement from the "quantity" factor. OBV index of energy tide was put forward by Grambi in 1960s, and it was widely used. The function of OBV index is mainly used to judge the relationship between volume and price, that is, whether the OBV curve is consistent with the running direction of stock price.
It should be noted that the obv indicator line has no parameters, and there is no need to set parameters when using it, which is different from most technical indicators. But obv index can also choose different average days, and judge the future change of obv index through different obv average lines.
What are the causes of stock index futures risk?
1, price fluctuation
The stock market is a barometer of the national economy. Affected by many political, economic and social factors, the stock price index has been changing. However, the unique operating mechanism of the stock index futures market may lead to frequent or even abnormal price fluctuations, which may lead to greater risks.
2. Leverage effect
Futures trading adopts the margin system, and traders can trade only by paying a certain percentage of the futures contract value, usually 5% ~ 10%. This high leverage effect not only attracts many speculators, but also magnifies the existing risks of price fluctuations. Small price changes can also lead to greater risks. When market conditions deteriorate, they may be unable to pay huge losses and default. The leverage effect of futures trading is the main sign that it is different from other investment tools, and it is also the main reason for the high risk of stock index futures market.
3. Irrational speculation
Speculators are an indispensable part of futures trading. They are not only the undertakers of price risks, but also the participants of price discovery, which not only promotes the reasonable formation of prices, but also improves market liquidity. However, in the case of imperfect risk management system, speculators are driven by interests, and it is easy to use their own strength, status and other advantages to manipulate the market and other illegal acts. This kind of behavior not only disturbs the normal order of the market, distorts the price and affects the realization of the price discovery function, but also causes unfair competition and damages the legitimate interests of other traders.
4. The market mechanism is not perfect.
In the operation of stock index futures market, there may be liquidity risk, settlement risk and delivery risk due to imperfect management regulations and mechanisms. In the early stage of the development of stock index futures market, this imperfect mechanism will produce corresponding risks, and may lead to the decline of arbitrage effectiveness between stock index futures and spot market, thus making it difficult for stock index futures to function normally.
What is the impact of stock delisting?
There are three possibilities for delisting, which have different impacts on investors:
First, under the premise of not violating laws and regulations, the company withdrew from the capital market because of poor management. Due to performance factors, the delisting standard of A-share companies is to suspend listing for three consecutive years (temporarily keep the code and qualification). If they continue to lose money after six months, they will face delisting. Before a listed company withdraws from the market, its stocks will fall one after another. It is difficult to sell stocks at this time. By the time the delisting is completed, investors have lost most of their funds.
Second, listed companies have not completely withdrawn from the capital market, and their stocks continue to trade in the third board market after delisting. The liquidity of the third board market is extremely poor, and most stocks have no trading volume for a day. It is impossible for investors to make a comeback through the third board market.
Third, because listed companies withdraw from the market due to financial fraud, information distortion and other reasons, investors can demand compensation from listed companies here.
For investors, in order to prevent the delisting risk of listed companies, we should actively pay attention to the financial information of listed companies and try to avoid buying stocks starting with ST, which generally have the risk of being terminated from listing. While the reform of the registration system continues to advance, the risk of delisting of listed companies will further increase. At that time, we will try our best to choose high-quality listed companies.
