Currency trading, also called foreign exchange trading (forex), is the process of buying one currency while simultaneously selling another, with the goal of profiting from fluctuations in their exchange rates. This market operates globally and is the most liquid financial market in the world, with a daily turnover exceeding $7 trillion.
In currency trading, all transactions occur in pairs, meaning you are trading the value of one currency relative to another.
Currency Pairs Explained
Each currency pair has:
Base Currency: The first currency in the pair
Quote Currency: The second currency in the pair
The currency pair shows how much of the quote currency is needed to buy one unit of the base currency.
Example:
If USD/INR = 83.00, it means 1 US Dollar is equal to 83 Indian Rupees.

How Currency Trading Works
Currency trading is driven by movements in exchange rates. Traders speculate whether a currency will appreciate or depreciate relative to another.

If you expect the US Dollar to strengthen against the Rupee, you may buy USD/INR
If you expect the Rupee to gain, you may sell USD/INR
This movement presents opportunities for traders to profit from both upward and downward shifts.
