🔍 How Volume Works in Technical Analysis?

🛠️ Step-by-Step Guide: Using Volume in Index Trading
Let’s walk through a practical way to apply volume to your trading.
✅ Step 1: Understand Basic Volume Principles
- A price rise on increasing volume = bullish signal
- A price rise on decreasing volume = weak or false move
- A price drop on increasing volume = strong bearish signal
- A breakout with low volume = likely to fail
✅ Step 2: Use Volume Indicators
You don’t have to guess. These volume-based tools simplify your analysis.
| Volume Tool | Purpose | Best Used For |
| Volume Bars | Raw volume per candle | Every chart |
| On-Balance Volume (OBV) | Tracks volume flow with price | Trend confirmation |
| Volume Weighted Average Price (VWAP) | Institutional buying/selling reference | Intraday/short-term trading |
| Accumulation/Distribution Line | Measures strength of buying/selling pressure | Breakout and trend analysis |
✅ Step 3: Confirm Breakouts with Volume
Breakout without volume = trap.
When an index like Nifty breaks a resistance level, always check if volume is above average.
Example: If Nifty breaks 23,000 with 2x average volume, the move is more reliable than a low-volume breakout.
✅ Step 4: Detect Reversals with Volume Divergence
- Price making new highs, but volume falling = bearish divergence
- Price making new lows, but volume falling = bullish divergence
These signals often precede major reversals.
📌 Real-World Example: Nifty Index Volume Confirmation
Let’s say Nifty is forming a bullish flag pattern.
You wait for a breakout at 22,500. When it happens, you check volume.
- If volume is 3x the average of the last 10 days → ✅ Strong breakout
- If volume is lower than average → 🚫 Risky, avoid trade
