I immediately lose my respect to you if you try to guess a stock's future price based on analyzing the graph, it's just useless!!

It's simply a flawed and misleading approach. Technical analysis might offer interesting patterns in hindsight, but relying on past price movements to forecast the future is no more reliable than reading tea leaves. The market is influenced by countless unpredictable factors (news events, economic shifts, human psychology) that a chart alone can’t possibly capture. Treating lines and patterns as if they hold some secret truth about where a stock is headed ignores the fundamental uncertainty and complexity of financial markets. It's not just unscientific, it's dangerous for real-world investing.
