I see many friends in trading groups still confused between demand and supply. Actually, it's not as difficult as you think. But if you understand it correctly, it will help you read the market more accurately.

Simply put, demand is the desire to buy, while supply is the desire to sell. Both of these are the driving forces behind the price of everything—from stocks, gold, energy, to cryptocurrencies.

When prices go up, consumers tend to buy less because it becomes more expensive (Income Effect). And when prices drop, people want to buy more. This is the basic law of demand, opposite to supply. When prices are high, sellers want to sell more because they can make more profit. When prices are low, sellers tend to hold back on selling.

What’s interesting is that the actual market price occurs at the equilibrium point, where the demand and supply curves intersect. If the price rises from this point, sellers see more selling opportunities. Meanwhile, buyers hold back on purchasing, leading to excess supply and downward pressure on the price. Conversely, if the price falls, buyers rush in, and sellers hold back, causing shortages and upward pressure on the price.

How demand and supply differ is based on their relationship with price. Demand is inversely related (price up, quantity bought down), while supply moves in the same direction as price (price up, quantity sold up).

In financial markets, factors affecting demand include interest rates, system liquidity, and investor confidence. Supply is influenced by company policies, capital increases, IPOs of new companies, and various regulations.

When we talk about stocks, demand and supply are the buying and selling forces battling every day. If buying power wins, prices go up. If selling power wins, prices go down. In fundamental analysis, we look at expectations about company performance and growth. In technical analysis, we use various tools to observe these forces.

Green candlesticks (closing price higher than opening) indicate buying strength, while red candlesticks (closing price lower than opening) show selling strength. Doji candles (opening and closing prices close together) suggest indecision, with both forces roughly equal.

Trend analysis also helps a lot. If prices keep making new highs, it shows strong buying. If prices keep making new lows, it indicates heavy selling. If prices move within a range, it means both forces are battling each other.

There’s a technique called Demand Supply Zone, used to observe trend changes. When prices move rapidly up or down and then pause within a range, it signals that both forces are fighting. When the price breaks out of that range, it indicates one force has gained the upper hand, and the price will continue in that direction.

For example, if the price drops sharply (Drop), then consolidates in a range (Base), and then rallies (Rally), it’s called a DBR (Demand Zone Drop Base Rally). Conversely, if the price rises (Rally), consolidates (Base), then drops (Drop), it’s called RBD (Supply Zone Rally Base Drop). We can trade at the breakout points of these ranges.

The difference between demand and supply is understanding this distinction, which helps us read the market better. When we see demand, we expect prices to rise; when we see supply, we expect prices to fall.

Learning this isn’t complicated, but it requires observing real price movements to see the picture. Notice how the market moves when good news comes out or during large sell-offs. You’ll see that demand and supply are real phenomena that happen every day.
