Forex trading works by simultaneously buying one currency and selling another. For example, if you believe the Indian Rupee (INR) will strengthen against the US Dollar (USD), you would sell USD/INR. Conversely, if you think the Rupee will weaken, you would buy USD/INR. The profit or loss is determined by the difference in exchange rates. Each currency pair has a bid price (sell price) and an ask price (buy price), with the spread being the cost of trade. In India, SEBI limits leverage to 1:50 for currency futures, meaning with ₹1,000, you can control a position worth up to ₹50,000. This amplifies both gains and losses, so risk management is critical. Indian traders can access forex through SEBI-registered brokers like Zerodha, Angel One, or ICICIdirect, which offer platforms like NSE NOW or TradingView. A practical example: Suppose USD/INR is trading at 83.50. You buy one lot (1,000 units) at 83.50, expecting the Rupee to weaken. If the price moves to 83.70, your profit is (83.70 - 83.50) x 1,000 = ₹200. If it drops to 83.30, your loss is ₹200. The market is influenced by factors like RBI interest rate decisions, inflation data, global oil prices, and geopolitical events. For Indian traders, the RBI's monetary policy and US Federal Reserve decisions are key drivers. Unlike stock trading, forex offers high liquidity and low transaction costs, but it requires a solid understanding of technical analysis, economic indicators, and discipline.
