Reading Price Charts
Reading a price chart correctly is the foundation of technical analysis. Let's understand what charts really tell us.
A price chart is a visual record of the battle between buyers and sellers. Learning to read it is like learning a new language.
The Price Axis
The vertical axis shows price levels:
- Higher on the chart = Higher price
- Lower on the chart = Lower price
Two scale types:
| Scale | How It Works | Best For |
|---|---|---|
| Linear | Equal spacing for equal price changes | Short-term charts |
| Logarithmic | Equal spacing for equal percentage changes | Long-term charts |
Use logarithmic scale for charts spanning years. A move from ₹100 to ₹200 (100%) should look the same as ₹1000 to ₹2000 (100%).
The Time Axis
The horizontal axis shows time:
- Moves left to right (past to present)
- Spacing depends on timeframe chosen
- Each candlestick/bar represents one time period
Reading Candlesticks
For each candlestick:
The Body
- Green/white body = Close higher than open (bullish)
- Red/black body = Close lower than open (bearish)
- Long body = Strong conviction
- Short body = Indecision
The Wicks (Shadows)
- Upper wick = Price tested higher but came back
- Lower wick = Price tested lower but recovered
- Long upper wick = Selling pressure appeared
- Long lower wick = Buying pressure appeared
Reading Price Action
| What You See | What It Means |
|---|---|
| Alternating colors | Indecision, sideways |
| Long body after small bodies | Breakout, momentum |
| Small body after long bodies | Exhaustion possible |
Volume Bars
Often shown below the price chart:
- Tall bar = High trading activity
- Short bar = Low trading activity
- Color usually matches price candle
Volume confirms price moves. A big move on high volume is more reliable than one on low volume.
What Charts DON'T Tell You
Charts show price and volume, but NOT:
- Why the move happened
- Fundamental value
- Future with certainty
- Whether to buy or sell (that's your interpretation)
Reading Trend Direction
Uptrend
- Higher highs (each peak higher than previous)
- Higher lows (each dip higher than previous)
Downtrend
- Lower highs
- Lower lows
Sideways (Range)
- Highs and lows roughly equal
- Price bouncing between levels
Key Price Levels
Watch for:
- Round numbers (₹100, ₹500, ₹1000)
- Previous highs and lows
- Gap areas
- Areas where price reversed before
These often act as support or resistance.
Common Beginner Mistakes
| Mistake | Why It's Wrong |
|---|---|
| Seeing patterns everywhere | Over-interpretation |
| Trading every signal | Overtrading |
Key Takeaways
- Vertical axis shows price, horizontal shows time
- Candlestick body shows open-close range
- Wicks show price rejection
- Volume confirms price moves
- Look for higher highs/lows (uptrend) or lower highs/lows (downtrend)
