#### Used margin calculation

Dollar settlement:

Used margin = market price at the time of the contract * contract unit * margin ratio * contractsize

Non-US dollar settlement:

Used Margin = Current Market Price * Contract Unit * Margin Ratio * Number of Contracts * Settlement Currency to US Dollar Exchange Rate

An example is as follows:

1. UKOUSD (UK Brent OIL)
UKOUSD which sells 10 contracts at a certain time on a certain day of the month, the selling price is 55.100, and the market price is 53.100/54.100 at some time on the next month. Used Margin = Market BID Price * Contract Unit * Margin Ratio * Contract Quantity = 53.100*1000*2%*10 =\$10620

2. SPXUSD (S&P 500)
The SPXUSD that buys 10 contracts at a certain time on a certain day of the month, the purchase price is 1400.00, and the market price is 1480.00/1481.00 at a certain time on the next month. Used Margin = Market ASK Price * Contract Unit * Margin Ratio * Contract Quantity = 1481.00 * 100 * 2.00% * 10 = \$29620

3. 100GBP (UK100)
buys 2 contracts of 100GBP at a certain time on a certain day of the month, the purchase price is 5700.0, the market price is 5799.0/5801.0 at a certain time on the next month, and the British pound exchange rate is 1.58540. Used Margin = Current Market Price * Contract Unit * Margin Ratio * Contract Quantity * GBP / USD Quote = 5801.0 * 10 * 4.00% * 2 * 1.58540 = 58010 * 4.00% * 2 * 1.58540 = \$7357.5

4. D30EUR (DAX30)
sells D30EUR for 5 contracts at a certain time on a certain day of the month. The selling price is 6900.0. The market price is 6998.0/7002.0 at a certain time on the next month, and the euro exchange rate is 1.33547. Used Margin = Current Market Price * Contract Unit * Margin Ratio * Contract Number * EUR / USD Quote = 6998.0 * 10 * 4.00% * 5 * 1.33547 = 69980 * 4.00% * 5 * 1.33547 = \$18691.2

*Margin used has nothing to do with long positions or short positions

#### Point value calculation

Valuation currency description:The currency in the currency pair is the denomination currency. For example, CHF in USD/CHF is the denomination currency.

Base point description:For the regular currency pair, the fourth digit after the decimal point is the base point (0.0001), for example: EUR/USD 1.10669
Japanese currency pair, the second digit after the decimal point is the base point (0.01), for example: USD/JPY 120.664
spot gold, after the decimal point The first place is the base point (0.1), for example: XAU/USD 1138.13
spot silver, the second place after the decimal point is the base point (0.01), for example: XAG/USD 15.299 In short, in the DTFOREX five-digit quotation system, the penultimate is base point.

Point value calculation formula:
Point value = Contract Size * Tick Size * Quote Currency Rate

An example is as follows:

1. Take USD/CHF as an example: Assume that the current exchange rate of USD/CHF is 0.95268, then the customer trades one standard lot per transaction. The point value is: USD/CHF point value = 100000*0.0001*(1/0.95268) = \$10.496

2. Take GBP/JPY as an example: Assume that the current exchange rate of GBP/JPY is 184.092, and the current exchange rate of USD/JPY is 119.289. The customer trades one standard lot per transaction. The point value is: GBP/JPY point value=100000*0.01 *(1/119.289 (USD/JPY))= \$8.383

3. Take GBP/NZD as an example: Assume that the current exchange rate of GBP/NZD is 2.27219, and the current exchange rate of NZD/USD is 0.67925. The customer trades one standard lot per transaction. The point value is: GBP/NZD point value=100000*0.0001 *0.67925 (NZD/USD)= \$6.7925

4. Take AUD/CHF as an example: Assume that the current exchange rate of AUD/CHF is 0.69072, and the current exchange rate of USD/CHF is 0.95268. The customer trades one standard hand per transaction. The point value is: AUD/CHF point value=100000*0.0001 *(1/0.95268(USD/CHF))= \$10.496

5. Take EUR/AUD as an example: 8:05 AM 2015-11-05 Assume that the current exchange rate of EUR/AUD is 1.56823, and the current exchange rate of AUD/USD is 0.72511. The customer trades one standard lot per trade, the point value is: EUR /AUD point value = 100,000 * 0.0001 * 0.72511 (AUD / USD) = \$7.2511

6. Take USD/CAD as an example: Assume that the current exchange rate of USD/CAD is 1.29256, and the customer trades one standard lot per transaction. The point value is: USD/CAD point value=100000*0.0001*(1/1.29256) = \$7.736

7. Take USD/TRY as an example: Assume that the current exchange rate of USD/TRY is 2.89330, and the customer trades one standard lot per transaction. The point value is: USD/TRY point value=100000*0.0001*(1/2.89330) = \$3.456

8. Take EUR/SEK as an example: Suppose the current exchange rate of EUR/SEK is 9.35928, and the current exchange rate of USD/SEK is 8.23098. The customer trades one standard lot per transaction. The point value is: EUR/SEK point value=100000*0.0001 *(1/8.23098(USD/SEK))= \$1.214

Take USD/CNH as an example: Assume that the current exchange rate of USD/CNH is 6.36370, then the customer trades one standard lot per transaction. The point value is: USD/CNH point value=100000*0.0001*(1/6.36370) = \$1.571

10. Take D30EUR as an example: Suppose the current price of D30EUR is 10121.0, the current exchange rate of EUR/USD is 1.13719, the customer trades a standard lot per trade, the point value is: D30EUR point value=100000*0.0001*1.13719 (EUR/USD ) = \$11.3719
