📈 Core Technical Indicators: Your Stock Market Weather Station
Imagine you’re a ship captain sailing the ocean. You can’t see underwater currents or predict storms just by looking at the sky. You need instruments—a compass, a barometer, a radar.
In the stock market, technical indicators are your instruments. They help you see what’s happening beneath the surface of price movements. They don’t predict the future perfectly (nothing does!), but they give you clues about where the “weather” might be heading.
Let’s explore your toolkit—one instrument at a time!
🌊 Moving Averages: The Smooth Ride
What Is It?
A Moving Average (MA) is like looking at your friend’s grades over time instead of just one test. If they got 70, 80, 90 on three tests, the average is 80. That’s smoother than the ups and downs of individual scores!
In stocks, we do the same with prices. Instead of looking at today’s wild price, we average the last few days to see the trend.
Two Types You’ll Meet
| Type | What It Does | Best For |
|---|---|---|
| SMA (Simple Moving Average) | Treats all days equally | Long-term trends |
| EMA (Exponential Moving Average) | Cares more about recent days | Quick reactions |
Simple Example
Imagine a stock’s prices for 5 days:
- Day 1: $10
- Day 2: $12
- Day 3: $11
- Day 4: $13
- Day 5: $14
5-day SMA = (10 + 12 + 11 + 13 + 14) ÷ 5 = $12
This $12 line on your chart shows: “On average, the stock is around $12.”
Why It Matters
- Above the MA? Price is doing better than average—bulls are winning! 🐂
- Below the MA? Price is weaker than average—bears might be in control! 🐻

✂️ Moving Average Crossovers: When Lines Talk to Each Other
The Big Idea
What if we used two moving averages—a fast one and a slow one? When they cross, it’s like a traffic signal changing!
The Golden Cross ✨
- Short-term MA (like 50-day) crosses ABOVE long-term MA (like 200-day)
- Signal: “Things are getting better! Consider buying.”
- Like a green traffic light turning on
The Death Cross ☠️
- Short-term MA crosses BELOW long-term MA
- Signal: “Danger ahead! Consider selling.”
- Like a red traffic light
Real Example
Imagine:
- 50-day MA: $45 → $48 → $52
- 200-day MA: $50 → $50 → $50
When the 50-day ($52) rises above the 200-day ($50), that’s a Golden Cross!

🎸 Bollinger Bands: The Rubber Band Effect
What Is It?
Bollinger Bands are like putting a rubber band around the price. The band stretches when prices go wild and squeezes when prices are calm.
There are 3 lines:
- Middle Band = 20-day Moving Average (the average)
- Upper Band = Middle + 2 standard deviations (the ceiling)
- Lower Band = Middle - 2 standard deviations (the floor)
The Squeeze and Pop 🍿
- Squeeze: Bands get narrow → Market is sleeping → Big move coming!
- Pop: Price touches upper or lower band → Possible reversal or breakout
Simple Example
If a stock’s 20-day average is $100 and prices are calm:
- Upper Band: $105
- Middle: $100
- Lower Band: $95
Price at $105 (touching upper band)? It might be overbought—like a rubber band stretched too far, it may snap back!
Key Rules
| Price Position | What It Means |
|---|---|
| Touches Upper Band | Possibly overbought |
| Touches Lower Band | Possibly oversold |
| Bands Squeeze | Big move coming! |
| Bands Widen | High volatility happening |
🌡️ RSI: The Fever Checker
What Is It?
RSI (Relative Strength Index) is like a thermometer for stocks. It measures if a stock is running a “fever” (too hot) or is “cold” (too weak).
RSI gives you a number from 0 to 100.
The Magic Numbers
- Above 70 = Overbought (stock is HOT—might cool down)
- Below 30 = Oversold (stock is COLD—might warm up)
- 50 = Neutral zone
Simple Example
A stock went up every day for 2 weeks:
- RSI: 85 (very overbought!)
- Meaning: “Whoa, this stock ran too fast. It might need a rest.”
A stock dropped for 10 days straight:
- RSI: 22 (very oversold)
- Meaning: “This stock is beaten down. It might bounce back!”

🚦 MACD: The Trend Traffic Light
What Is It?
MACD (Moving Average Convergence Divergence) sounds scary, but it’s just watching two moving averages dance together or apart.
The Three Parts
- MACD Line = Fast EMA (12-day) minus Slow EMA (26-day)
- Signal Line = 9-day average of the MACD Line
- Histogram = The bars showing the gap between MACD and Signal
How to Read It
- MACD crosses ABOVE Signal = Buy signal 🟢
- MACD crosses BELOW Signal = Sell signal 🔴
- Histogram growing = Trend getting stronger
- Histogram shrinking = Trend getting weaker
Simple Example
Imagine:
- Fast average: $50
- Slow average: $48
- MACD Line = $50 - $48 = $2
If yesterday MACD was $1 and Signal was $1.5, but today MACD is $2 and Signal is $1.8:
- MACD ($2) is above Signal ($1.8) = Bullish crossover!

🎢 Stochastic Oscillator: The Roller Coaster Position
What Is It?
Imagine you’re on a roller coaster track. The Stochastic Oscillator tells you: “Are you near the top of the hill or near the bottom?”
It compares today’s price to the price range over a period (usually 14 days).
The Numbers
- Scale: 0 to 100
- Above 80 = Near the top (overbought)
- Below 20 = Near the bottom (oversold)
Two Lines
- %K = The fast line (current position)
- %D = The slow line (3-day average of %K)
Crossover Signals
- %K crosses above %D in oversold zone (below 20) = Buy signal!
- %K crosses below %D in overbought zone (above 80) = Sell signal!
Simple Example
A stock’s range over 14 days: Low $40, High $60
Today’s price: $58
Stochastic = (58 - 40) / (60 - 40) × 100 = 90%
This means: “The stock is 90% of the way up its recent range—near the ceiling!”
🔢 Fibonacci Tools: Nature’s Secret Numbers
The Story
There was a mathematician named Fibonacci who discovered a magic pattern in nature: 1, 1, 2, 3, 5, 8, 13, 21…
Each number is the sum of the two before it. Strangely, these numbers create ratios that appear everywhere—in sunflowers, shells, and yes, stock prices!
The Golden Ratios
From Fibonacci numbers, we get these key percentages:
- 23.6%
- 38.2%
- 50% (not actually Fibonacci, but widely used)
- 61.8% (the golden ratio!)
- 78.6%
How Traders Use Them
Fibonacci Retracement: When a stock pulls back, these levels often act as “support floors.”
Example:
- Stock rose from $100 to $200
- It starts to fall back (retrace)
- Traders watch: Will it bounce at 38.2% ($161.80) or 61.8% ($138.20)?
Fibonacci Extension: After a pullback ends, these predict how far the next move might go.
graph TD A[Stock Falls from Peak] --> B{Watch Fib Levels} B --> C[23.6% - Shallow pullback] B --> D[38.2% - Normal pullback] B --> E[50% - Halfway bounce] B --> F[61.8% - Deep pullback] B --> G[78.6% - Very deep pullback]
Simple Example
Stock went from $50 to $100:
- Range = $50
- 38.2% retracement = $100 - (0.382 × $50) = $80.90
- 61.8% retracement = $100 - (0.618 × $50) = $69.10
If the stock drops and bounces right at $80.90, Fibonacci traders say: “See! The 38.2% level held!”
🎯 Putting It All Together
Each indicator is one instrument. Smart traders use multiple indicators together:
| Indicator | Best For | Quick Check |
|---|---|---|
| Moving Averages | Trend direction | Above MA = bullish |
| MA Crossovers | Trend changes | Golden Cross = buy |
| Bollinger Bands | Volatility | Squeeze = big move coming |
| RSI | Overbought/Oversold | >70 hot, <30 cold |
| MACD | Momentum | Line crosses Signal |
| Stochastic | Position in range | >80 top, <20 bottom |
| Fibonacci | Support/Resistance | 61.8% is the magic level |
The Weather Report Approach 🌤️
Think of it like checking the weather:
- Moving Average = What’s the season? (overall trend)
- RSI = Is it unusually hot or cold today?
- MACD = Is the weather changing?
- Bollinger Bands = Is a storm brewing?
- Stochastic = Where are we in the daily cycle?
- Fibonacci = Where are the natural rest stops?
