Notice that many people still do not understand how demand and supply differ, but they are actually the core of price movements in the real market.

Simply put, demand = the desire to buy, and supply = the desire to sell. When more people want to buy but there are few items for sale, prices go up. Conversely, when there are many items for sale but no one wants to buy, prices go down. This system applies to stocks, gold, oil, and even digital assets.

I want you to understand that demand and supply are not as complicated as you might think. Once you grasp the basics, you'll see why prices change.

Demand represents the desire to buy at different price levels. The simple rule is: if the price drops, people want to buy more; if the price rises, they want to buy less. Because when prices decrease, our wallets become more valuable, or when this type of product becomes cheaper, it looks more attractive compared to alternative goods.

Supply is the willingness of producers to sell. When prices go up, sellers want to sell more because the profit is better. Conversely, if prices fall, sellers are less eager to sell.

The key point is that demand and supply must meet at a point called "equilibrium." This is the price that the market accepts, where no one wants to change it. If the price is above this point, there will be excess supply, pushing the price down. If it’s below, there will be shortages, pushing the price up.

In financial markets, demand and supply are not solely dependent on price. Many other factors influence them, such as investor confidence, economic news, company policies, or even political situations.

A clear example is oil earlier this year when the Strait of Hormuz was closed, causing 20% of global oil to disappear from the market. Supply sharply decreased, but energy demand remained the same. The result was an immediate surge in prices.

For traders, understanding demand and supply helps improve price prediction. I see many use the Demand Supply Zone technique to find trading opportunities by identifying points where the market is out of balance and waiting for prices to return to equilibrium.

For example, if prices drop rapidly (excess supply) and then stop and start forming a base, it signals that demand is returning, and prices might reverse upward. Conversely, if prices rise sharply and then slow down and form a base, it indicates selling pressure returning, and prices could decline.

Another important aspect is observing support and resistance levels. Support is where demand is waiting to buy, and resistance is where supply is waiting to sell. When prices hit support, they often reverse upward; when they hit resistance, they tend to reverse downward.

What I like about this technique is that it links economic theory with real trading, not just numbers and formulas, but understanding the market psychology—where people want to buy and sell.

If you truly learn this, you should study real price charts to see when demand and supply cause price changes. You can also look at data across different markets on Gate, as each asset tends to behave similarly.

In summary, demand and supply are the fundamental rules driving all markets. Understanding them gives you an advantage in investing.
