Algorithmic trading uses computer programs to automatically execute trades based on predefined strategies, while manual trading requires the trader to analyze the market and place trades themselves. Algo trading removes emotion, allows 24/7 trading, and reacts to signals faster than a human could.
You can start forex trading with as little as $100, though many brokers recommend $500–$1000 for more flexibility and lower risk per trade. Always start with money you can afford to lose and test strategies on a demo account first.
Forex trading is legal in most countries when done through regulated brokers. However, it's a high-risk market. Safety depends on your broker’s credibility, your trading knowledge, and your use of proper risk management.
