Currencies are traded in pairs in order to express the relative value of one currency against the value of another. The first currency in the pair is refferred to as the base currency while the second currency in the pair is the quote one. The relation of the two values is the quotation of the currency pair.

In Forex you capitalize on currency rate fluctuations. The more the rate changes the bigger your profit or loss is.
It is important to understand that a decreasing rate may be just as benefitial as the rising one.
Such actions in both cases constitute a complete trading operation in which you first open a trading position by whatever action you take and then subsequently close your open position by taking an action that is offset to the original one and at a newer price.
At every moment of time a currency pair is always quoted double price: Bid for sale and and Ask for purchase of a base currency in a pair for the quote one.

This quotation means we may immediately:
The complete trading operation involves both prices Bid and Ask because opening and closing a position means carrying out trasnactions that are offset to one another:
IMPORTANT Do not forget that charts are only constructed using the Bid price. Ask price is always spread-distance higher than what the chart shows.
Spread is the difference between Bid and Ask prices. It is the size of the transaction cost which varies from pair to pair. Spread volume is measured in pips. In our case the EURUSD spread is 2 pips.
Pip (percentage in point) is a volume unit and equals the smallest currency rate increment (0.0001 for most currency pairs that are quoted to the fourth decimal point). Pips are used to measure rate fluctuations and spreads.
The monetary value of a pip depends on the volume involved and expressed in units of quote currency.
Example A: 1 pip volume in EUR/USD is 0.0001
| Trading position volume | Calculation | 1 pip value |
| 100,000 EUR | 100,000 * 0.0001 | 10 USD |
| 10,000 EUR | 10,000 * 0.0001 | 1 USD |
| 1,000 EUR | 1,000 * 0.0001 | 0.1 USD |
| 100 EUR | 100 * 0.0001 | 0.01 USD |
Example B: 1 pip volume in USD/JPY is 0.01
| Trading position volume | Calculation | 1 pip value |
| 100,000 USD | 100,000 * 0.01 | 1000 JPY |
| 10,000 USD | 10,000 * 0.01 | 100 JPY |
| 1,000 USD | 1,000 * 0.01 | 10 JPY |
| 100 USD | 100 * 0.01 | 1 JPY |
As you can see, a pip value (price) goes down as a position (trade) volume decreases and is nominated in a second currency in a pair (Quoted Currency).
A concept of pip value allows to measure the monetary value of the smallest possible rate change in relation to the volume of a specific trading operation.
Once completed a trading operation always results in either profit or loss.
Buy 200,000 USD/JPY:
A differential between the initial Ask and the last Bid prices is 75 pips.
There are two ways of calculating our profit:

Our profit is 150,000 JPY (or 1,555,5325 USD)

Forex Trading is trading on margin. WIth trading leverage offered by broker you only need your margin to cover positions you open.
If you have 1,000 USD in your account and your maximum available leverage is 1:100, you are able to trade 100 times the volume of your balance which is 100,000 USD.
