I just realized an interesting thing: most people who lose money in the market aren’t losing due to poor analytical skills, but because they don’t know whether they’re a Trader or a Holder. That’s the life-or-death boundary that very few people explain clearly.

Stock trading isn’t gambling, even if it looks similar on the surface. It’s a real profession built on probability, statistics, and psychology. Traders don’t wait for a company to spend 5 years building a factory before they can profit—they take advantage of psychological fluctuations within the day and within the week to make money.

There are two completely different ways of playing: Holders (long-term investors) treat stocks as part of the company’s ownership; they care about financial reports, management, and competitive advantages. Traders, on the other hand, only see a stock as a “string of moving characters,” don’t care what the company sells, and only care whether cash flow is flowing in or being withdrawn. Holders use fundamental analysis, while Traders use technical analysis (charts, indicators, price behavior). This difference determines 80% of trading outcomes.

In terms of methods, stock trading has three main schools. Scalping is ultra-short-term trading—enter and exit within a few seconds to minutes, earning very tiny spreads but placing hundreds of orders per day. It’s extremely stressful, and transaction fees quickly erode profits. Day Trading holds a position during the day, looking for stocks with hot stories to take advantage of strong intraday ranges. The trap is overtrading—trading too much after consecutive losses. Swing Trading (trading based on waves) is the most suitable for 80% of investors who have a 9 to 5 job. Hold for several days to a few weeks, wait for a clear trend, look for pullback timing to enter, and take profit at the next wave’s peak. You capture thicker profit segments (5–15% per trade) with less psychological pressure.

But technique accounts for only 20%; the rest is psychology and capital management. The market is driven by two emotions: Greed and Fear. FOMO makes you buy at the top, while FUD makes you sell at the bottom. What really matters is how much you’ll lose if you’re wrong, not how much you can make.

Golden rule: never let the risk on a single trade exceed 2% of your total account. For example, with 1 million in capital, your maximum risk is 20k. Always look for opportunities with a minimum Risk/Reward ratio of 1:2 (willing to lose 1 to gain 2). With a Winrate of only 40%, a 1:2 strategy is still profitable in the long run.

What’s F0’s most deadly mistake? Chasing falling knives—buying more when the price drops to lower your average cost is the shortest path to going bankrupt. Recklessly abusing Margin—it’s a double-edged sword: profits double, but the risk of account blow-up increases exponentially. Revenge trading—after being cut from a losing trade (stopped out), anger makes you re-enter with a larger volume, breaking all risk management.

When you start stock trading, you need a strong trading foundation (an intuitive interface, fast order matching, low fees), proficiency with analysis tools (TradingView, MA, Volume, support/resistance), and most importantly, a trading journal—writing down why you entered, why you exited, and what you felt at that moment. That’s the greatest teacher.

The standard order-entry process: first, look at the daily chart (D1) to identify the main trend—never trade against it. Find strong support/resistance zones, then wait for the price to retrace. Watch for triggering signals (reversal candles, volume surges). Finally, calculate your order size and set a hard Stop-loss immediately.

A specific feature of Vietnam’s market is the T+2.5 regulation—after buying, you have to wait more than 2 days for the stock to arrive in your account before you can sell. That’s why Day Traders in Vietnam often switch to derivatives (VN30 futures) or international CFDs, because the T+0 mechanism is more flexible.

In the end, what distinguishes a person from a gambler is psychological discipline and risk management. You don’t need to be right all the time—just keep the amount you lose when you’re wrong as small as possible, and capture the whole move when you’re right. The person who survives the longest in the market is the winner, not the one who makes the most money in a single month.
