I just noticed that there is an interesting aspect about price movements in the market. Stocks, oil, gold, and even digital assets are all driven by the same principle: supply and demand.

This may sound complicated, but put simply, it’s a clash between buyers and sellers. Once you understand this, you can see why prices move the way they do.

Let’s start with demand, which is the desire to buy. The more people want to buy, the higher the price rises. Its rule is that when the price gets more expensive, demand decreases because people feel it’s too costly. Conversely, if the price falls, demand increases because people think, “The price is lower now—buy now.” There are many factors that affect demand, such as consumers’ income, expectations about the future, or even news that makes people experience FOMO.

Supply is the desire to sell. When prices rise, sellers are more willing to sell more. But when prices drop, sellers won’t want to sell, or they will reduce their selling quantity. Supply is influenced by production costs, technology, and even government policies.

Most importantly, when the supply and demand curves intersect, that point is called equilibrium. At this point, prices tend to stay stable, because if anyone tries to move the price, there will be a pullback force. A clear example is when “ฮอร์มุซปิดตัวลง” due to the situation in the Middle East. The oil that flows through this point makes up about 20% of the world’s total, and it disappears immediately. This causes a massive reduction in oil supply, while demand (demand) remains the same. The result is that prices surge sharply in a volatile way.

In financial markets, this principle also works. When the economy is doing well, demand for stocks increases as people try to seek returns. When interest rates are low, people don’t like to keep money in banks, so they buy stocks instead. The supply of stocks depends on company decisions, such as share buybacks or issuing new shares.

For traders, understanding supply and demand helps you predict prices better by looking at candlestick charts. If the candle is green (closing higher than opening), it indicates strong demand. If it’s red (closing lower than opening), it indicates that supply has won. In addition, there is the Demand Supply Zone technique, which identifies potential support and resistance areas. When price breaks out of the range, there’s a chance for a big move.

There are two trading styles. The first is catching reversals—when price moves too far away from equilibrium, it will reverse back. The second is trend-following—when new factors come in, price keeps moving in the same direction.

The truth is, no matter what market it is, the principles of supply and demand still remain the foundation. Learning to read these signals well can help you make smarter investment or trading decisions. Take a look at the prices of various assets on Gate and observe when demand is strong and when supply has momentum—the more clearly you can see these patterns, the better you’ll be at catching the right moments.
