Forex trading is the process through which you buy and sell various currencies. There is a global foreign exchange market where this buying and selling process occurs. It's done in currency pairs, where traders speculate on the exchange rate fluctuations between two currencies, aiming to profit from those changes.

In Forex trading, the entire process is done when you buy one currency and sell another simultaneously. The goal is to predict currency pair movements accurately, earning a profit when the value of your bought currency rises compared to the sold currency.

A currency pair represents the exchange rate between two currencies. It indicates how much of the quote currency is needed to buy one unit of the base currency.

The spread in Forex represents the difference between the buying price (ask price) and the selling price (bid price) of a currency pair. It is essentially the transaction cost for trading currencies, expressed in pips.

Several key factors impact Forex prices, including interest rates, inflation, economic growth, political stability, and the supply and demand of currencies driven by international trade and investment flows.

In Forex, a pip (percentage in point) represents the smallest price increment a currency pair can make. It's typically the last decimal place in a currency quote. For most pairs, a pip is 0.0001 (or 1/100th of a cent).

Leverage in Forex trading is like a loan from your broker, allowing you to control a larger position with a smaller amount of your own capital. It magnifies both potential profits and losses.

Margin in Forex is not a fee but rather the amount of money required in your account to open and maintain a leveraged trading position. It acts as collateral, enabling you to control larger positions than your account balance.

A stop-loss order is an instruction to a broker to sell a security when it reaches a specific price, limiting potential losses in a volatile market. It acts like an automatic safety net for your investments.

Forex trading can be profitable, but it's highly risky. Success demands significant knowledge, skill, and discipline due to market volatility and leverage. Many lose money, so it's crucial to approach it with caution and realistic expectations.
