I just skimmed through a discussion about forex investing and realized that way too many newcomers are entering the market without knowing how to manage risk. In fact, the figure that 90% of new investors lose money in the first 90 days is not random—they simply step onto the battlefield without understanding the rules of the game.

The foreign exchange market is a complex ecosystem. It doesn’t have a physical center like a stock exchange; instead, it operates 24/5 via an electronic network among banks, financial institutions, and individual investors. Daily trading volume can reach up to 7 trillion USD—that’s an enormous number. In this system, where do you stand? You’re Tier 4—a small fish in the ocean. The good news is that you still have the chance to make money from price movements, especially when you use leverage.

When talking about forex investing, people often forget that you’re not buying a physical banknote. You trade the exchange rate between two currencies. For example, EUR/USD = 1.1050 means you need 1.1050 USD to exchange for 1 EUR. It’s that simple—but from there, a whole series of concepts comes into play: Pip, Lot, Margin, Leverage, Spread.

I learned that a Pip is the smallest unit of price movement (usually the 4th decimal place). If EUR/USD rises from 1.1050 to 1.1051, you’ve made 1 Pip. A Lot is the trading size—1 Standard Lot equals 100,000 units of the currency. Leverage is leverage that lets you borrow money from the broker to trade a larger volume. But this is a double-edged sword—it can help you make big gains or suffer big losses.

Compared with traditional stocks, forex investing clearly has advantages: extremely high liquidity, trading 24/5, the ability to short-sell, and low costs. But the price you pay is that the risk is also higher. The market can turn its back on you at any moment.

The most important thing I’ve learned is risk management. Never risk more than 2% of your total account balance on a single trade. If your account has $1,000, your maximum risk is $20. Always use a Stop Loss—there’s no such thing as a “Mental Stoploss.” Set it firmly on the system as soon as you open the trade.

The Risk:Reward ratio also matters. You don’t need to be correct 100%. Professional traders only need a win rate of 40%, and they still get rich because of the R:R. If you lose 1 when you’re wrong and gain 2 when you’re right, then after 10 trades (losing 6, winning 4), you’re still up 2.

On analysis, I realized you need to combine both fundamental (fundamental) and technical (technical) analysis. Fundamental news creates trends—FED interest rate policies, inflation data, employment reports. Technical analysis helps you find the optimal entry points—support, resistance, and price behavior. Never gamble on the market before the NFP or CPI release time if you don’t have a profit buffer. Your order can slip, and your Stop Loss can be triggered in an instant.

There are 4 main trading styles. Scalping is ultra-short-term trading (a few seconds to a few minutes), requiring quick screen reaction and a very high level of focus. Day trading means holding positions for a few hours, always closing before going to sleep. Swing trading catches big swings, holding for days to weeks. Position trading is long-term trading, measured in months or years. Each style has different requirements for time, psychology, and capital.

By the way, I want to warn you about Prop Firms (funding firms). In 2026, many of these will appear, but there are also many “junk” firms that only make money from failed applicants. Avoid firms with hidden rules, system errors, or delayed payouts. Some firms look for unreasonable rule violations, cause extremely heavy slippage, or freeze funds without paying. Before taking a prop challenge, you need a trading system with consistently stable profitability.

In terms of legality in Vietnam, as of 2026, the State Bank has not licensed any forex exchange within the country. But the law also does not prohibit individuals from opening accounts at international exchanges. However, behavior such as soliciting others, multi-level marketing, or promising “guaranteed profits with guaranteed returns” is a serious violation of the law.

Stay away from scam exchanges. Warning signs: promising huge profits (20-30%/month), lacking international licenses from ASIC, FCA, CySEC, CIMA, or having deposit/withdrawal issues (fast deposits but delaying withdrawals). When Gold prices jump sharply, many “shady” exchanges have already blocked withdrawals and changed prices to save themselves. Choosing a reputable exchange with negative balance protection is essential.

If you’re busy with an administrative job, the best trading sessions are the European session (14h00 - 23h00 VN time) and the US session (19h00 - 04h00 VN time). These are the times with the largest ranges—when it’s easiest to make money.

Finally, if you’re planning to start, spend at least 1 month learning Japanese candlesticks in depth, support and resistance, and Dow theory. Then open a demo account and follow a 2% discipline rule for at least 3 months. Keep a trading journal—write down why you entered each trade and what your psychology was like at that time. Finally, deposit a small amount of capital to truly experience that “psychological pain.” That’s when you learn the most valuable lessons about forex investing—not from textbooks, but from your own decisions.
