Initially, pinpoint the current price on your chart. Next, direct your attention to the chart's left side and search for a pronounced and vigorous sequence of candles, either ascending or descending. Generally, supply zones are identified by a robust upward progression in preceding price action, indicating strong selling interest. Conversely, demand zones are typically characterized by a significant downward trajectory in prior price movements, signaling strong buying interest. This distinction is key to understanding market dynamics and identifying potential trading opportunities.
