Trading charts visualize price history and help you make informed decisions. Without charts, you're trading blind - like driving without a windshield.
Charts answer key questions:
Is the price trending up or down?
Where might price reverse (support/resistance)?
Is momentum increasing or decreasing (volume)?
Should I buy, sell, or wait?
Candlestick Charts: The Standard
What is a Candlestick?
A candlestick shows price movement over a specific time period (1 minute, 5 minutes, 1 hour, 1 day, etc.). Each candlestick displays four critical prices:
Open: Price when the period started
Close: Price when the period ended
High: Highest price during the period
Low: Lowest price during the period
Anatomy of a Candlestick
High (Wick/Shadow)
|
┌────┴────┐
│ Body │ ← Close (if green) / Open (if red)
│ │
│ │
└────┬────┘ ← Open (if green) / Close (if red)
|
Low (Wick/Shadow)
Body: The thick part (Open to Close)
Wicks (Shadows): The thin lines extending above/below the body
Green vs Red Candles
🟢 Green (Bullish): Close > Open (price went up)
Open: $50,000
Close: $52,000
Result: Green candle, $2,000 gain
🔴 Red (Bearish): Close < Open (price went down)
Open: $50,000
Close: $48,000
Result: Red candle, $2,000 loss
Reading a Candlestick
Example 1: Strong Bullish Candle
High: $52,500
Close: $52,000 ─┐
│ Large green body = strong buying
Open: $50,000 ─┘
Low: $49,800
Interpretation: Price opened at $50K, dipped slightly to $49.8K, then buyers pushed it all the way to $52.5K, closing at $52K. Strong bullish momentum.
Interpretation: Price opened at $50K, swung wildly between $49K and $51K, but closed almost unchanged at $50.05K. Bulls and bears fought, neither won. Indecision.
Support is a price level where buying pressure is strong enough to prevent further decline. Think of it as a floor that price bounces off.
Why it exists: Traders see that price level as a "bargain" and start buying aggressively.
Example:
BTC drops from $60K → $50K
At $50K, buyers step in and push price back up
$50K becomes a known support level
Next time BTC approaches $50K, traders anticipate support and buy early
Resistance: The Ceiling
Resistance is a price level where selling pressure prevents further gains. Think of it as a ceiling that price struggles to break.
Why it exists: Traders who bought lower take profits at that level, creating selling pressure.
Example:
BTC rises from $40K → $50K
At $50K, sellers overwhelm buyers and price drops
$50K becomes known resistance
Next time BTC approaches $50K, traders anticipate rejection and sell
Support Becomes Resistance (and Vice Versa)
Key Concept: When support breaks, it often becomes resistance. When resistance breaks, it often becomes support.
Example:
$60K ○ ← Breaks resistance, now tests as support
╱│
$55K ───●────○──────○──│ ← Old resistance
╱ ╲ ╱ │
$50K ─●────────●──●────○ ← Resistance becomes support after breakout
How to Find Support/Resistance
Historical levels: Where price repeatedly bounced or rejected
Psychological numbers: $50K, $100K (humans love round numbers)
Moving averages: 50-day, 200-day MA often act as support/resistance
Trend lines: Connect swing lows (uptrend) or swing highs (downtrend)
Volume: The Fuel of Price Moves
What is Volume?
Volume measures how much of an asset traded during a period. High volume = high interest/conviction. Low volume = weak move.
Key Principle:Price moves on volume. A breakout without volume is likely a false breakout.
Volume Bars
Most charts show volume as bars below the price chart:

Practice Exercises
Open any chart (Cryptonyk, TradingView, Coinbase) and identify:
Is the trend up, down, or sideways?
Where is the nearest support level?
Where is the nearest resistance level?
Zoom in/out between 1-hour and daily charts. Do the trends match?
Watch volume during a price move. Does high volume confirm the move?
Find a recent breakout. Did it have strong volume? Did it continue or reverse?

Practice Recommendation: Spend 15-30 minutes daily watching charts on Cryptonyk. Don't trade yet - just observe price action, identify trends, and mark support/resistance levels. Chart-reading is a skill that improves with repetition.
