Volume is the cornerstone of technical analysis because it reveals the conviction behind price movements. While price tells you what happened, volume tells you how many participants agreed with that movement. This fundamental concept separates strong, sustainable trends from weak, temporary price fluctuations.
🔑 Core Volume Principle
Volume should confirm price action. When price moves in a direction with increasing volume, it indicates strong market consensus. When price moves with decreasing volume, it suggests weak conviction and potential reversal.
In Indian markets, understanding volume becomes even more critical due to the presence of both retail and institutional participants. Smart money (institutions) often moves differently from retail investors, and volume patterns can help you identify when institutional money is flowing into or out of a stock.
