What is Foreign Exchange Trading?

Foreign exchange trading, also known as Forex trading, is the exchange of one currency for another on the foreign exchange market. This is done in order to take advantage of the perceived value of one currency over another. The Foreign Exchange market is the largest financial market in the world, with an estimated daily trading volume in excess of US $5 trillion. It is one of the most actively traded markets in the world, with traders taking positions in currencies from all major economies. The Forex market is open 24-hours a day, five days a week and is accessible from anywhere in the world.

What is Percentage Change?

In Forex trading, percentage change is used to measure the relative strength or weakness of a currency against another currency. The formula for calculating percentage change is simple: (previous price – current price) / previous price x 100. This measurement is useful for traders when trying to identify trends. A trader can quickly identify if the value of one currency is increasing or decreasing compared to another.

How To Use Percentage Change?

The percentage change formula allows traders to quickly determine the value of a currency in relation to another currency. By using this formula, traders can identify the direction of the market and decide whether to buy or sell. For example, if the percentage change of a particular currency is increasing against another currency, the trader may decide to buy it. Conversely, if the percentage change of a particular currency is decreasing against another currency, the trader may decide to sell it.

When a trader decides to take a position in a currency pair, they must also consider the implications of FX risk. Potential losses due to unanticipated changes in exchange rates should be calculated. This is an important consideration when trading currencies.

In conclusion, Forex trading is particularly complex due to the presence of multiple currencies and the risk associated with exchange rate fluctuations. The use of the percentage change formula is a key tool which allows traders to quickly assess the direction of the market. By understanding the basics of the percentage change formula, traders can better manage their risk and make more informed decisions when trading.

What is Percentage Change?

Percentage Change refers to the shift in value expressed in terms of a percentage due to a change from one number to another. Percentage change can denote a decrease in value as well as an increase in value. This shift in value can be measured in the form of points, decimals, and percentages depending on the amount of change. It is a crucial concept to understand in economics, particularly when calculating the rate of inflation and deflation.

How Can We Measure a Change in Percentage?

Calculating the change in percentage requires knowledge of the current number and the old number. Subtracting the prior index value from the later one is the primary method in finding the percent change. That difference should then be divided by the earlier index value to reveal the percentage of change. Alternatively, it can be found by dividing the changes in values by the earlier index directly.

Formatting the Percentage Change Formula

The formula for calculating a percentage change will often look something like this:

% Change = (New/Old -1) x 100

In this formula, you are entitled to use either a positive or a negative number for both the new and the old numbers. A good rule of thumb to remember when calculating a percentage change is to always subtract the earlier number from the later number.

This formula can be used to both increase and decrease in value. It requires knowledge of prior and current values in order to get an accurate representation of the percentage change.

How to Calculate a Percentage Increase

The percentage increase formula is used to tell us how much a value has increased from its previous value. To calculate the percentage increase formula, you will first need to determine the difference in values between the prior and the current. Then divide the increase by the prior number. Finally, convert the result to a percentage by multiplying it by 100.

For example, if the prior value was $800 and the current value is $1,000 the percent increase can be calculated by subtracting the prior from the current: $1,000 – $800 = $200.
The percent increase is then determined by taking the difference and dividing it by the prior value. In this example, $200/$800 = 0.25. Then multiplying by 100, the percent increase to $1,000 is 25%.

How to Calculate A Percentage Decrease

The percentage decrease formula works much like the percentage increase formula. It will tell us the percent decrease of a value from its previous status. To calculate a percentage decrease, you will first need to determine the difference in value between the prior and the current number. Then divide the decrease by the prior number. Finally, convert the answer to a percentage by multiplying it by 100.

For example, if the prior value was $800 and the current value is $500, the decrease can be found by subtracting the prior from the current: $500 – $800 = -$300. The percent decrease then would be determined by taking that difference (-$300) and dividing it by the prior value. In this example, -$300/$800 = -0.375. Then multiplying by 100, the percent decrease to $500 is 37.5%.

Conclusion

Finding the percent change between two numbers is an important part of economic analytics. It can be used to calculate the rate of inflation and deflation, and is necessary for understanding market trends. The percentage change formula is simple to use and easy to understand, simply requiring knowledge of the prior and current values, and the application of basic math operations. By calculating the difference between current and prior values and then dividing it by the prior, you can find both increases and decreases in percentages successfully.
