I've just noticed that people are talking about demand and supply very frequently these days, especially when the market is highly volatile. And I realized that this is still a fundamental rule that drives the prices of all kinds of assets, whether stocks, energy, gold, or even digital assets.

Actually, demand and supply are not as complicated as you might think. It’s simply the desire to buy versus the desire to sell. When these two sides meet, they create a price called equilibrium or the point of balance.

Just think about it: if the price of a product drops, people have more leftover money (income effect) and will compare it to similar products (substitution effect). The result of these two effects is an increase in demand. Conversely, if the price rises, people will buy less. The demand and supply sides are similar; when prices are high, sellers are willing to sell more, and when prices are low, they are willing to sell less.

In financial markets, the factors influencing demand and supply are quite complex. On the demand side, it depends on economic growth, interest rates, liquidity in the system, and investor confidence. When interest rates are low, people tend to invest more in stocks for higher returns. On the supply side, it depends on company policies, new listings, and market regulations.

An interesting point is that prices change based on investor confidence. If a company's profit is expected to increase, buyers are willing to pay higher prices or buy in larger quantities. Meanwhile, sellers may hold back from selling. The result is a price increase. Conversely, if negative news comes out, buyers hold back, and sellers are willing to lower prices, causing the price to drop accordingly.

When it comes to technical analysis, demand and supply are used to infer buying and selling pressure in the market, using tools like candlestick analysis. If the candlestick is green (closing higher than opening), it indicates buying strength. If it’s red (closing lower than opening), it indicates selling strength. Doji candles, where opening and closing prices are close, mean both sides have equal strength.

Trend analysis is another way to clearly see demand and supply. If prices keep making new highs, it shows strong demand. If prices keep making new lows, it indicates strong supply. If prices fluctuate within a range, it means both sides are exerting equal pressure.

Support and resistance levels are also created by demand and supply. Support is usually where buyers are waiting, and resistance is where sellers are waiting. When prices break through resistance, it shows that demand has overcome selling pressure.

A real-world example of applying this principle is the Demand Supply Zone technique, which looks for moments when prices move rapidly up or down and then pause within a range before continuing or reversing. The DBR (Drop Base Rally) pattern occurs when excess supply causes prices to plunge, then pause before rising again. The RBD (Rally Base Drop) pattern is the opposite: prices rise, pause, then fall.

Trend trading is more common than trading reversals. RBR (Rally Base Rally) occurs when demand remains strong, with prices rising, pausing, then rising again. DBD (Drop Base Drop) is the opposite: prices fall, pause, then fall further.

In summary, demand and supply are not just economic theories but real mechanisms that drive market prices. If we understand which force is winning at the moment, we can better predict the market direction. It’s not difficult if you just try applying it to real prices and keep studying. The more you observe real prices, the clearer the picture becomes.
