I've just noticed that many people talk about supply and demand, but few truly understand what they are and why they are important for investing.

In fact, supply and demand are the fundamental driving forces behind everything in the market, whether it's stocks, gold, or even digital assets. When more people want to buy (demand) than want to sell (supply), prices go up. Conversely, when more people want to sell than buy, prices fall.

Think simply: if you see a stock's price drop, and you want to buy it, then if others think the same way, everyone wants to buy but no one wants to sell, the price will quickly rise. That’s how supply and demand work.

Factors affecting demand include many things, such as the overall economy, interest rates, investor confidence, and even news or global events. When interest rates are low, people tend to shift their investments into stocks because bank deposits offer too little return.

As for supply, it depends on how many shares companies issue. Corporate policies like share buybacks or issuing new shares also influence supply. Other factors include production costs, technology, and even weather conditions that may impact manufacturing.

What’s interesting is that when the demand and supply lines intersect, that’s the equilibrium point where price and volume stabilize. If prices go above this point, sellers want to sell more, but buyers want to buy less, leading to excess supply and a price correction downward. Conversely, if prices fall below this point, buyers want to buy more, but sellers want to sell less, causing shortages and prices to rise.

A clear example is oil during the Strait of Hormuz closure. Oil supply drops significantly, but energy demand remains, causing prices to spike rapidly. That’s a real-world "Supply Shock."

When it comes to trading, many investors use these principles of supply and demand to time their entries. They look at candlestick charts: a green candle (closing higher than opening) indicates strong buying pressure, while a red candle (closing lower than opening) shows selling pressure.

Another method is observing support and resistance levels. Support is where buying interest is waiting, and resistance is where selling interest is waiting. When prices approach support, there’s often a surge of buying. When approaching resistance, selling tends to increase.

Using Demand and Supply Zones in trading comes in various patterns, such as DBR (Drop Base Rally), which occurs after a price plunge creates a base and then reverses upward, or RBD (Rally Base Drop), which is the opposite pattern. Traders can enter trades at breakout points of these ranges.

In summary, supply and demand are key to understanding price movements, whether through fundamental or technical analysis. If you can grasp how buying and selling forces operate, you’ll be able to predict prices more accurately. It might be helpful to test this principle in real markets to deepen your understanding of how supply, demand, and price are interconnected.
