I just realized that all asset prices, from stocks and gold to cryptocurrencies, are driven by the same thing. That is the balance between those who want to buy and those who want to sell. Once you understand this, predicting prices becomes almost straightforward.

Supply and demand are concepts everyone has heard of but not deeply understood. In reality, they are just the desire to buy and the desire to sell. When more people want to buy, prices go up. When more people want to sell, prices go down. That’s how it works.

Let’s go into detail. On the demand side, it’s the number of people willing to buy at different prices. If the price is low, more people buy. If the price is high, fewer people buy. This is a basic rule because when prices drop, our money lasts longer (income effect), and we can compare it to other goods (substitution effect). On the supply side, it’s the opposite: sellers want to sell more when prices are high and reduce their volume when prices are low.

But the actual market price doesn’t depend solely on supply or demand. It depends on the point where the two lines intersect—that is, the equilibrium point. At that point, price and quantity tend to stay stable because if the price rises above that point, excess supply will push prices down. If the price drops below, shortages will push prices up.

In financial markets, supply and demand become more complex. Demand depends on macro factors like interest rates, economic growth, liquidity in the system, and investor confidence. Supply depends on corporate decisions such as share buybacks, capital increases, and new listings.

For fundamental analysis, rising stock prices indicate strong demand. Falling prices show heavy supply. These driving factors aren’t from the stock itself but from the expected value of the company. If a company is expected to grow well, buyers are willing to pay higher prices, while sellers hold back, pushing prices up.

For technical analysis, there are many tools. Green candlesticks indicate strong demand; red candlesticks indicate strong supply. Doji suggests both forces are balanced. If prices keep making new highs, demand still wins. If prices keep making new lows, supply still wins. Support levels are points where demand is waiting to buy; resistance levels are points where supply is waiting to sell.

A popular current technique is the Demand Supply Zone, which identifies moments when prices move rapidly up or down and then pause within a range. Afterward, traders wait for the price to break out of that range. There are two types: the first (DBR) is when the price plunges, pauses, then reverses upward—buy on the breakout above the range. The second (RBD) is when the price rises, pauses, then reverses downward—sell on the breakout below the range.

In reality, trend-following movements happen more often than reversals. For example, (RBR) is when prices go up, pause, then continue upward. (DBD) is when prices drop, pause, then continue downward. Traders need to follow the trend and wait for the price to break out in the same direction.

In summary, supply and demand are the fundamental gears of the market. Whether it’s commodities, stocks, or crypto, everything depends on this balance. If you understand it well, you can predict prices more accurately. But it requires practice and continuous study of real price movements—there’s no shortcut in this.
