相對離散指數(Relative Volatility Index,簡稱RVI)又稱“相對波動率指標”,用於測量價格的發散趨勢,由著名分析家唐納德·多西(Donald Dorsey)於1993年提出。其原理與相對強弱指標(RSI)類似,但它是以價格的方差而不是簡單的升跌來測量價格變化的強度。
相對離散指數(RVI)主要用作輔助的確認指標,即配合均線系統、動量指標或其他趨勢指標使用。用於RVI綜合了多種不同的因素,通常比其他輔助指標要好。
RVI 公式
相對波動率指數的計算方式與 RSI 的計算方式類似。回想一下,RSI 是使用以下公式計算的:
RSI = 100 – 100 / 1 + 相對強度
這個公式分為三個部分。首先,您必須計算相對強度。您可以通過首先計算第一個平均收益和第一個平均損失來做到這一點。
這些是通過在一定時期內進行收益總和並將總收益除以時期來計算的。第一次平均損失的計算方法相同。然後計算平均收益和平均損失。
相對波動率的計算方法類似。但是,不同之處在於,如上所述,它使用標準差。
通過首先計算平均值來計算標準偏差。這是通過將所有值相加並除以 period 來完成的。然後減去每個數字的平均值,然後將結果平方。然後,您應該計算這些平方差的平均值並找到它們的平方根。
對於大多數交易者來說,這聽起來可能很困難。但是,正如我們之前所寫,您只需要知道如何應用和解釋該指標。
在 MT4 等許多平臺中,該指標未作為默認設置。但是,它可以在這些平臺上下載和安裝。
如上所示,相對波動率指數只是一條上下移動的線。在圖表中添加它時,您只需選擇它並選擇所需的設置。您只能更改指標的顏色、長度以及超買和超賣水準。
如何在交易中使用相對波動率指數
有兩種主要的解釋 RVI 的方法。應用時,RVI 值從零移動到 100。主要看線 的是 20 和 80。
1、當RVI大於50時,可以買入。
2、當RVI小於50時,可以賣出。
3、RVI指標一般作為輔助指標使用。
RVI指標的標準差週期可設置為10天,RVI週期可設置為14天。
對流方法是分別使用 20 和 80作為超賣和超買水準。這意味著您應該在資產價格升至超賣水準時買入,並在價格升至超買水準時做空。
還有其他交易者使用不同的方法。
他們在 RVI 向上移動時買入,即使達到超買水準也繼續持有交易。他們在 RVI 走低時賣空交易,即使達到超賣水準也繼續持有。
這樣做的原因是,他們認為當達到這些超買和超賣水準時,勢頭不會停止。
與相對強弱指數 (RSI) 一樣,您也可以使用 RVI 來查找資產的背離。當資產價格上漲而指標朝相反方向移動時,就會出現背離。當它發生時,通常是價格即將反轉的信號。
使用 RVI的另一種方法是將其與其他動量、成交量和趨勢指標結合使用。組合很重要,因為它有助於消除錯誤突破的可能性。
相對波動率在金融市場上不是一個流行的指標。事實上,在 MetaTrader 4 和 MetaTrader 5 等大多數平臺中,該指標並未作為預建工具提供。

What is Forex?
Foreign exchange trading (or Forex for short) refers to the exchange (also called buying and selling) of currencies in different countries. The foreign exchange market is one of the fastest growing markets in the world in recent years. Forex trading is open 24 hours a day, 5 days a week, trading uninterruptedly.
In fact, Forex trading is very similar to stock trading-buy low and sell high. But the advantage of foreign exchange trading is that you do not need to screen thousands of industries and companies. Forex trading is much simpler than choosing good stocks.
If you have just entered the Forex market, you can trading based on your views on the economy and future development of specified countries you want to invest in. Buying and selling currencies is as simple as buying and selling ordinary commodities.
At the same time, the trading hours of the foreign exchange market are not limited. The foreign exchange market is open 24 hours a day, 5 days a week. For traders all over the world, flexible transactions can be carried out at any trading time, not limited to computers, web pages, and mobile phones.
02
What is Currency Pairs?
When we trade Forex, we are actually buying one currency and selling another currency at the same time. This is why Forex is traded at the exchange rate of a "currency pair".
As the name implies, major currencies refer to several currencies that are frequently traded in the world, including Euro (EUR), U.S. Dollar (USD), Japanese Yen (JPY), British Pound (GBP), Australian Dollar (AUD), and Swiss Franc (CHF), etc. . The figure below lists several major currencies and their issuing countries and symbols.

03
What is Spread?
Each currency pair listed has an exchange rate, which consists of a "sell" price and a "buy" price. The sell price is the price at which the broker sells a given currency pair, and the buy price is the amount the broker is willing to pay for buying this currency pair. The difference between the selling price and the buying price is called the spread. The smaller the spread, the more fees you will save per transaction.
In JRFX, we have dozens of tradable currency pairs, and the spread is as low as 0.0 pips.
04 What’s the relationship between Forex market and interest rate?
Have you noticed that experienced Forex investors often pay attention to the interest rates?
*High interest rates will help a country attract foreign investment, thereby increasing the demand for money, which in turn will cause the currency to increase.
Interest rates are like a barometer of a country's economy. As a country's economy strengthens, consumers will have more disposable income, and prices will rise accordingly, causing inflation. The central bank of each country will take measures to raise interest rates to ease inflationary pressure before it gets out of control. The result of high interest rates is that economic growth slows down until the central bank starts to lower interest rates to encourage economic growth and expansion.
The trend of interest rates is generally speculated based on the central bank’s statements and meeting minutes. This is why investors tend to analyze word by word to determine what possible interest rate moves the central bank will make at the next meeting. Therefore, the direction of interest rates is often more important than the interest rate decision itself.
05
What’s Other Factors affect Forex?
Apart from interest rates, there are many other factors affecting the medium and long-term trend of Forex market, including gross domestic product (GDP), US non-farm payrolls (NFP), consumer price index (CPI), producer price index (PPI), durable goods orders, claims for unemployment benefits, industrial production index, trade balance, unemployment rate, retail sales, etc. Differences between published data and expectations will have different impacts on currency pairs.
06
Types of Forex Trading Market
The foreign exchange market (FX Markets) is usually classified according to the time of the transaction, and there are spot market (Spot), forward market (Forward), swaps (Swaps) and futures markets(Futures).
Spot foreign exchange transaction (Spot), also as known as spot transactions, refers to the fact that after the transaction of foreign exchange transactions, both parties to the transaction conduct delivery on the same day or within two business days. Currency prices are determined by supply and demand, macroeconomics, and national policies.
On the other hand, contracts traded in forward and futures market represent a demand for a certain currency type, with a specific price and future settlement date for each unit.

What is Bitcoin-halving?
The so-called "halving" is a unique issuing mechanism of bitcoin. According to the Bitcoin white paper, this mechanism was designed when Bitcoin was born. Halving Bitcoin means that the reward for producing a new block is halved about every four years. This means that every time a Bitcoin miner validates a transaction, Bitcoin's revenue is reduced by 50%.
02
Why halving bitcoin?
After successfully mining a bitcoin, the bitcoin miner will receive a block reward-essentially a bitcoin payment. However, the process of halving Bitcoin follows the theory of cryptocurrency economics. Because the quantity of Bitcoin is limited and its supply decreases over time, it is possible to keep the price of Bitcoin "stable" and deflationary by reducing the total supply, which is why Bitcoin is halved.
03
Historical bitcoin-halving date
Halving Bitcoin is a quadrennial event. On November 28, 2012, Bitcoin halved for the first time, rising 77.65 times from $13.49 to $1047.5; the second halving occurred on July 10, 2016, when Bitcoin soared from $620 to $18711, a more than 30-fold increase. Bitcoin was halved for the third time on May 12, 2020, and the Bitcoin Block Award was reduced from 12.5 Bitcoins to 6.25 Bitcoins as Block 630,000 was dug up. The third official halving of Bitcoin did not lead to the bull market expected by the market, closing the day at $8821.43, up 2.9 per cent.
As for the volatility before halving, several industry insiders said in an interview that the main reason was that the expectation of halving Bitcoin was realized ahead of time. "the impact of the third halving of Bitcoin and the wider audience, the market is actually more concentrated and unstable." However, a halving of Bitcoin is bound to lead to a rise in the price of the currency, and the third halving may lead to a bull market in a year's time. As you can see, in each halving event, the number of bitcoins dug up and block rewards have been halved. By 2032, more than 99% of bitcoins will be mined, and it is estimated that 100% of bitcoins will not be mined until 2140.
The next half of Bitcoin is expected to happen on May 9, 2024. Halving the bitcoin this time will reduce the mining bonus from 6.25 bitcoins to 3.125 bitcoins.
04
Advantages and disadvantages of Bitcoin-halving
Halving in nominal value could be seen as a negative event, especially for bitcoin miners. However, the halving event may have a positive impact on investors and traders. As the price of Bitcoin rises after each halving, Bitcoin owners will benefit from a rise in the value of their assets. Halving demand for Bitcoin is often a good thing because of reduced supply, which is often seen as a major factor driving up the price of Bitcoin and other knockoffs in the future. But traders must also recognize the possible negative impact of halving bitcoin. Some analysts predict that halving could cause losses to other counterfeit coins. As mining costs suddenly double and miners may sell their reward bitcoins, Bitcoin may face a huge risk of collapse.
Halving bitcoin is often accompanied by price fluctuations, which can be positive or negative. Price volatility usually increases before and after the halving event. Traders can take advantage of fluctuations to make a profit. However, sharp price fluctuations may also make the pricing model elusive, thus affecting the implementation of trading strategies.
05
How to use Bitcoin-halving to make a profit
Previous halving events have led to a rise in the price of bitcoin. However, the environment for each halving is different, and demand for bitcoin is likely to fluctuate sharply, especially during the current pandemic. This has proved to be an economic test for even the most "stable" assets. For the encryption market as a whole, Bitcoin is often a bellwether of the market trend. When Bitcoin rises, most major cryptocurrencies usually keep rising for quite a long time, so counterfeit coins are positively correlated with the Bitcoin bull market. The term "a rising tide lifts all boats" is the most appropriate way to describe the impact on coins, which have been in a bull market after each halving in the past. Although the global economy is in turmoil and almost all assets are suffering losses, Bitcoin owners are likely to reap the benefits of halving again.

01
What are commodities?
A commodity is an economic good, usually a resource, that has full or substantial fungibility. Most of commodities are raw materials, basic resources, agricultural, or mining products, such as sugar, grains, coffee bean, tea and iron ore.
Note: According to Bloomberg News on 18 September, 2015, U.S. regulators formally define cryptocurrencies, such as Bitcoin, as commodities, which are the same as crude oil or wheat.
02
Why do we trade commodities?
Markets for trading commodities can be very efficient. These markets will respond to changes in supply and demand to find an equilibrium price and quantity quickly. Moreover, investors can gain passive exposure to the commodity markets through a commodity price index.
Because inflation hurts ordinary investment products, trading commodities can protect investors from inflation. This is because when the prices of goods or services rise, the value of the commodities needed will also rise. Accordingly, if your portfolio includes certain commodities, you may be able to reduce losses owing to inflation.
03 What are main commodities in financial market?
In the financial market, commodities are homogeneous, tradable, and widely used as industrial basic raw materials, such as crude oil, non-ferrous metals, agricultural products, iron ore and coal.
Commodities are divided into three categories: energy commodities, basic raw materials and agricultural products.
Commodities can be designed as futures and options as financial instruments to trade. Since commodities are mostly industrial basic raw materials, which are in the most upstream, the changes in futures and spot prices that reflect their supply and demand relationships will directly affect the entire economy. For example, rising copper prices will increase industries such as electronics and construction. Investors should pay close attention to the supply and demand and price changes of commodities.
