Forex trading works by speculating on the price movements between two currencies. For example, when you trade EUR/USD, you are buying the euro and selling the US dollar. If you believe the euro will strengthen against the dollar, you go 'long' (buy); if you think it will weaken, you go 'short' (sell). Profits or losses come from the difference in exchange rates. For Argentina traders, the most common base currency is USD, as it offers stability compared to the peso. You can trade major pairs like USD/JPY, GBP/USD, or even exotic pairs involving the Argentine peso (USD/ARS), though the latter is highly volatile and often restricted by brokers. Trading is done through a broker platform, where you deposit funds using local methods. For instance, you can deposit $500 USD via USDT, then trade with leverage up to 1:30 (for retail traders under ESMA rules, though Argentina has no specific cap, so be cautious). Each trade has a 'pip' (percentage in point) movement, and your profit or loss is calculated based on the lot size. A standard lot is 100,000 units of currency, but most retail traders use micro or mini lots (1,000 or 10,000 units). For example, if you buy EUR/USD at 1.1000 and it rises to 1.1050, you gain 50 pips. With a micro lot, each pip is worth $0.10, so you'd earn $5. In Argentina, this can be significant given the peso's depreciation.
