I've just noticed that many people still don't understand how important supply and demand are to investing. In fact, they are the core of all price movements, whether it's stocks, oil, or even digital assets.

The rule of demand is that it’s the desire to buy and the desire to sell. It sounds simple, but if you understand it deeply, it can help you read the market much better. When the price goes up, the desire to buy decreases (because it gets more expensive), but the desire to sell increases. Conversely, when the price drops, the desire to buy increases, but the desire to sell decreases.

What you need to understand is that the prices you see in the market actually occur at the equilibrium point of both sides — called Equilibrium. If there is good news, buyers are willing to buy at higher prices, and sellers hold back from selling, so the price rises. On the other hand, bad news causes buyers to reduce their purchases, and sellers rush to sell, so the price falls.

In financial markets, this is even more complex because many factors come into play, such as interest rates, system liquidity, investor confidence, company policies, and even geopolitical situations. For example, recently, tensions in the Middle East caused oil demand to spike rapidly.

If we understand this basic concept, we can read trading techniques better. For example, if the price creates a Demand Zone (a point where buyers are waiting to buy) and then reverses upward, that’s a good sign. Conversely, if the price breaks through support and drops, it indicates that selling pressure has overtaken buying pressure.

Most importantly, don’t overthink it. Supply and demand are about buying and selling forces. If buying is strong, prices go up; if selling is strong, prices go down. Let the market tell us what’s happening, and then we can make decisions.
