Seeing news about the global situation and conflicts in the Middle East, I can't help but think about oil and rising prices, which are related to the most fundamental aspect of the market: supply, the relationship between demand and supply.

Actually, supply is a key factor that drives the prices of everything—whether stocks, energy, gold, or even digital assets. When we understand how demand and supply work, we can see why prices move the way they do.

Let's start with the basics: demand is the desire to buy, and supply is the desire to sell. When prices drop, people want to buy more, but sellers are less willing to sell. Conversely, when prices rise, sellers want to sell more, but buyers reduce their demand. This is a fundamental rule that never changes.

What’s interesting is that the actual market prices are determined by the equilibrium point where the demand and supply curves intersect. If the price exceeds this point, surplus inventory occurs, causing prices to fall back down. If the price is below this point, shortages happen, pushing prices up. This equilibrium is the price the market needs.

In financial markets, this gets more complex. Many factors influence demand, such as interest rates. When interest rates are low, investors seek returns in the stock market. Investor confidence also plays a role. When the economy looks good, people want to invest more. Supply in the stock market may come from companies issuing new shares or IPOs.

Let’s look at a real-world example: in March 2026, the Strait of Hormuz was closed, cutting off over 20% of the world's oil flow from the market. This is called a supply shock. Oil demand (demand) remained the same, but supply dropped sharply. The result was a rapid increase in prices.

For traders, understanding supply and demand is very helpful. If stock prices fall, it indicates more selling pressure. If prices rise, it indicates more buying pressure. You can observe this through candlestick charts: green (closing price higher than opening) shows buying dominance; red (closing lower than opening) shows selling dominance.

There’s also the Demand Supply Zone technique, used to find buy and sell opportunities. When prices rise quickly and then pause within a range, it signals that buying and selling forces are battling. When the price breaks out of that range, it can be a good entry point.

Reversal trading occurs when prices move too far and new factors cause a change in direction—for example, a sharp drop (DBR). When selling pressure eases and buying comes in, prices start to reverse upward. Continuation trading happens when the trend persists—for example, prices rise and pause (RBR), and then, with good news, they continue upward.

Remember, supply is the foundation of all price movements. Whether you analyze fundamentally (company value and profits) or technically (candlesticks and trends), you must understand how buying and selling forces operate.

Learning this isn’t hard if you pay close attention to real market prices. Try looking at different stocks on Gate or other platforms, and observe when prices go up or down, what changes occur—whether due to news, earnings, or market confidence. You’ll see how supply and demand actually work in real life.
