🔍 What Is Technical Analysis?

Technical analysis (TA) is the study of past price and volume data to forecast future price movements. Instead of examining a company's financials (that's fundamental analysis from Lesson 6), technical analysis focuses entirely on the stock chart — the visual record of what buyers and sellers have done.

Core Assumptions of Technical Analysis

Assumption What It Means
Price discounts everything All known information — earnings, news, expectations — is already reflected in the stock price. You don't need to know why a stock is moving; the chart shows you that it's moving.
Prices move in trends Once a trend begins, it's more likely to continue than reverse. Identifying the trend early is the key to profitable trading.
History tends to repeat Human psychology doesn't change. The same patterns of fear and greed create similar chart patterns over and over again.

📊 TA Is a Probability Tool, Not a Crystal Ball

Technical analysis doesn't predict the future with certainty — nothing does. What it does is help you identify higher-probability setups and manage risk. Think of it like a weather forecast: it's not always right, but it's a lot better than guessing. The best investors combine TA with fundamental analysis — using FA to decide what to buy and TA to decide when to buy it.

📊 Chart Types: Line, Bar, and Candlestick

Stock charts come in several formats. Each shows price data differently, offering varying levels of detail.

Chart Type What It Shows Best For
Line Chart A simple line connecting closing prices over time Seeing the big picture — overall trend direction at a glance. Great for beginners and long-term investors.
Bar Chart (OHLC) Vertical bars showing open, high, low, and close for each period. Small horizontal ticks mark the open (left) and close (right). Traders who want full OHLC data in a compact format. Common in older charting software.
Candlestick Chart Like bar charts, but the body between open and close is filled/colored — green for up, red for down. The most popular chart type today. Easy to read at a glance, rich in information. This is the one you should learn.

Timeframes

Every chart has a timeframe — the period each bar or candle represents:

Timeframe Each Candle = Used By
1-minute / 5-minute 1 or 5 minutes of trading Day traders (buying and selling within the same day)
1-hour 1 hour of trading Swing traders (holding for days to weeks)
Daily 1 full trading day The standard for most investors and swing traders. Start here.
Weekly / Monthly 1 week or 1 month of trading Long-term investors looking at the big picture

🕯️ Reading Candlestick Charts

Candlestick charts are the foundation of technical analysis. Each candle tells you four things about a single time period: where the price opened, the highest it reached, the lowest it dropped, and where it closed.

Anatomy of a Candlestick

Part What It Shows
Body The thick part — spans from open to close. Green (bullish): close > open (price went up). Red (bearish): close < open (price went down).
Upper Wick (Shadow) The thin line above the body — extends to the session's high. Shows how far buyers pushed the price up before sellers pushed back.
Lower Wick (Shadow) The thin line below the body — extends to the session's low. Shows how far sellers pushed the price down before buyers stepped in.

Common Candlestick Patterns

Certain candle shapes appear so frequently that traders have named them. Here are the most important ones for beginners:

Pattern What It Looks Like What It Suggests
Doji Tiny or no body — open and close are nearly the same. Wicks can vary. Indecision. Neither buyers nor sellers won. Often signals a potential reversal when it appears after a strong trend.
Hammer Small body at the top, long lower wick (2× the body length), little or no upper wick. Bullish reversal signal when found at the bottom of a downtrend. Sellers pushed the price down, but buyers fought back hard and closed near the high.
Shooting Star Small body at the bottom, long upper wick, little or no lower wick. (Inverse of hammer.) Bearish reversal signal when found at the top of an uptrend. Buyers pushed up but sellers took control by close.
Engulfing (Bullish) A large green candle whose body completely "engulfs" the previous red candle's body. Strong bullish reversal. Buyers overwhelmed sellers. More powerful at the end of a downtrend.
Engulfing (Bearish) A large red candle whose body completely engulfs the previous green candle's body. Strong bearish reversal. Sellers overwhelmed buyers. More powerful at the end of an uptrend.
Marubozu A long body with no wicks at all — open equals the low (bullish) or high (bearish). Extreme conviction. Buyers (green) or sellers (red) were in total control with no pushback.

⚠️ Context Matters More Than the Pattern

A hammer at the bottom of a long downtrend is meaningful. The same candle shape in the middle of a sideways range is much less significant. Always consider where a pattern appears — at support/resistance levels, after extended trends, or near key moving averages — before acting on it. A single candle pattern alone is never enough to make a trade.

🧱 Support & Resistance

Support and resistance are price levels where buying or selling pressure has historically been strong enough to stop or reverse the price. They're arguably the most useful concepts in technical analysis.

Level What It Is Why It Works
Support A price level where the stock has repeatedly bounced upward — a "floor" that catches falling prices. At this price, enough buyers step in to absorb selling pressure. Traders remember where they got a good deal last time and buy again there.
Resistance A price level where the stock has repeatedly stalled or reversed downward — a "ceiling" that blocks rising prices. At this price, enough sellers take profits or new shorts enter to overwhelm buyers. Traders who bought lower sell to lock in gains.

Key Principles

Principle Details
More touches = stronger level A support level that has been tested and held 5 times is much stronger than one tested once. Each successful test reinforces the level in traders' minds.
Roles reverse when broken When support breaks, it often becomes new resistance (and vice versa). This is one of the most reliable patterns in TA. Example: a stock breaks below $50 support. When it later bounces back to $50, that old support now acts as resistance.
Round numbers are magnetic Prices like $50, $100, $200 often act as support/resistance because humans place orders at round numbers. "I'll sell if it hits $100" is a common thought process.
Breakouts need volume confirmation A breakout through resistance on high volume is more likely to hold than one on low volume. Volume validates the move.

📊 Support & Resistance Zones

Support and resistance are better thought of as zones rather than exact prices. A "support at $50" might actually be a zone from $49 to $51 where buying picks up. Don't expect the price to stop at exactly $50.00 every time — the concept is about areas of concentration, not precise levels.

📏 Moving Averages (SMA & EMA)

A moving average smooths out price data by creating a constantly updated average price over a specific period. It filters out day-to-day noise and reveals the underlying trend direction.

Simple Moving Average (SMA)

💡 SMA Formula

SMA = Sum of closing prices over N periods ÷ N

A 50-day SMA adds up the last 50 closing prices and divides by 50. Each day, the oldest price drops off and the newest is added.

Exponential Moving Average (EMA)

The EMA gives more weight to recent prices, making it more responsive to new information. It reacts faster to price changes than the SMA, which treats every day equally.

Feature SMA EMA
Weighting Equal weight to all periods More weight on recent prices
Responsiveness Slower to react — smoother line Faster to react — hugs price more closely
False signals Fewer (because it's smoother) More (because it's more reactive)
Best for Identifying longer-term trends Catching trend changes earlier

Key Moving Average Periods

Period What It Represents How Traders Use It
20-day ~1 month of trading Short-term trend. Often used by swing traders. Price above 20-day = short-term bullish.
50-day ~2.5 months of trading Medium-term trend. Widely watched by both traders and investors. A key level for institutional buying/selling.
200-day ~10 months of trading Long-term trend. The most important moving average. Price above 200-day = long-term bullish. Below = bearish.

Moving Average Crossovers

Signal What Happens Interpretation
Golden Cross ✨ 50-day SMA crosses above the 200-day SMA Bullish signal — suggests the start of a major uptrend. Widely watched by institutional investors.
Death Cross 💀 50-day SMA crosses below the 200-day SMA Bearish signal — suggests the start of a major downtrend. Often triggers institutional selling.

⚠️ Moving Averages Are Lagging Indicators

Moving averages are based on past data, so they always lag behind the current price. A golden cross, for example, often occurs after a significant portion of the uptrend has already happened. They're great for confirming trends but not for catching the exact bottom or top. Use them alongside other tools, not as standalone buy/sell signals.

⚡ RSI: Relative Strength Index

The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and magnitude of recent price changes. It helps you gauge whether a stock is overbought (price has risen too fast) or oversold (price has fallen too fast).

💡 RSI Basics

RSI is displayed as a number between 0 and 100, plotted on a separate panel below the price chart. The standard setting uses the last 14 periods (14 days on a daily chart).

How to Read RSI

RSI Level Condition What It Suggests
Above 70 Overbought The stock may have risen too quickly and could be due for a pullback or pause. Doesn't mean "sell immediately" — strong stocks can stay overbought for a while.
50 Neutral / Midline Balanced momentum. RSI above 50 generally confirms an uptrend; below 50 confirms a downtrend.
Below 30 Oversold The stock may have fallen too quickly and could be due for a bounce. Doesn't mean "buy immediately" — weak stocks can stay oversold for a long time.

RSI Divergence

One of RSI's most powerful signals is divergence — when the RSI moves in the opposite direction of the price:

Divergence Type What Happens Signal
Bullish Divergence Price makes a lower low, but RSI makes a higher low Selling momentum is weakening — a reversal to the upside may be coming
Bearish Divergence Price makes a higher high, but RSI makes a lower high Buying momentum is weakening — a reversal to the downside may be coming

📊 RSI Best Practices

Don't use RSI alone to make buy/sell decisions. Instead, use it as confirmation: if a stock pulls back to support AND RSI is near 30 (oversold), that's a stronger buy signal than either one alone. Similarly, if a stock hits resistance AND RSI is above 70, the risk of a pullback is higher.

📊 MACD: Moving Average Convergence Divergence

The MACD (pronounced "mac-dee") is a trend-following momentum indicator that shows the relationship between two moving averages. It's one of the most popular and versatile indicators in technical analysis.

MACD Components

Component What It Is Default Setting
MACD Line The difference between the 12-period EMA and the 26-period EMA 12-period EMA − 26-period EMA
Signal Line A 9-period EMA of the MACD line itself — a smoother, slower version 9-period EMA of MACD
Histogram Bar chart showing the difference between the MACD line and the signal line MACD Line − Signal Line
Zero Line The center line — when MACD is at zero, the 12 EMA and 26 EMA are equal —

How to Read MACD Signals

Signal What Happens Interpretation
Bullish Crossover MACD line crosses above the signal line Upward momentum is building — potential buy signal
Bearish Crossover MACD line crosses below the signal line Downward momentum is building — potential sell signal
MACD above Zero Line The 12 EMA is above the 26 EMA Overall trend is bullish — short-term momentum exceeds long-term
MACD below Zero Line The 12 EMA is below the 26 EMA Overall trend is bearish — short-term momentum trails long-term
Growing Histogram Bars getting taller (in either direction) Momentum is accelerating — the trend is strengthening
Shrinking Histogram Bars getting shorter Momentum is fading — a crossover or trend change may be approaching

💡 MACD + RSI = Powerful Combination

Many traders use MACD and RSI together. MACD tells you the direction and strength of the trend. RSI tells you if the stock is stretched too far in that direction. When both agree — for example, MACD bullish crossover + RSI bouncing off 30 — the signal is much more reliable than either one alone.

📊 Volume Analysis

Volume is the number of shares traded during a given period. It's the most underrated tool in technical analysis — price tells you what happened, but volume tells you how much conviction was behind it.

Volume Rules of Thumb

Volume Pattern Price Action Interpretation
High volume Price moves up Strong bullish conviction — lots of buyers stepping in. The rally is more likely to continue.
High volume Price moves down Strong bearish conviction — heavy selling pressure. The decline is more likely to continue.
Low volume Price moves up Weak rally — not many participants are buying. The move may fizzle out.
Low volume Price moves down Weak selling — could just be lack of buyers rather than active selling. Less concerning than high-volume drops.
Volume spike Breakout above resistance Confirms the breakout is real — institutions are participating. A breakout on low volume is more likely to be a "false breakout."
Declining volume During a trend The trend is losing steam. Fewer people are participating, suggesting a reversal or consolidation is near.

💡 Volume Confirms Everything

Think of volume as a lie detector for price action. A breakout, a reversal, a trend — they're all more trustworthy when backed by high volume. When you see a big price move, the first thing to check is: "Was volume above average?" If yes, take it seriously. If no, be skeptical.

📊 Average Volume Comparison

Most charting platforms show a volume moving average (often 50-day) overlaid on the volume bars. This makes it easy to see whether today's volume is above or below average. You're looking for volume 1.5× to 2× average or higher to consider it significant. The raw number doesn't matter — 5 million shares might be high for a small-cap and low for Apple.

🧩 Putting It All Together

No single indicator is reliable on its own. The power of technical analysis comes from confluence — when multiple tools point in the same direction.

A Beginner's TA Checklist

Step What to Check Tool
1. Identify the trend Is the stock in an uptrend, downtrend, or sideways? Price action, trendlines, 200-day MA
2. Find key levels Where are the nearest support and resistance zones? Horizontal lines, previous highs/lows, round numbers
3. Check moving averages Is price above or below the 50-day and 200-day? Any crossovers? 50 SMA, 200 SMA
4. Read momentum Is the stock overbought or oversold? Is momentum building or fading? RSI (14), MACD
5. Confirm with volume Is volume supporting the move? Are breakouts backed by high volume? Volume bars, volume MA

⚠️ Common Beginner Mistakes

Mistake Better Approach
Using too many indicators — chart looks like a rainbow Stick to 2–3 indicators max. More isn't better — it's confusing.
Trading based on a single signal Wait for confluence — at least 2–3 signals pointing the same way.
Ignoring the overall trend Never fight the trend. A "buy signal" in a strong downtrend is usually a trap.
Looking for perfect signals They don't exist. TA gives probabilities, not certainties. Accept that some trades will lose.

🎯 Key Takeaways

Concept What to Remember
Candlesticks Body = open to close. Wicks = high and low. Green = up, Red = down. Key patterns: doji, hammer, engulfing.
Trends Higher highs/higher lows = uptrend. Lower highs/lower lows = downtrend. Trade with the trend, not against it.
Support & Resistance Support = floor (buying zone). Resistance = ceiling (selling zone). Broken support becomes resistance, and vice versa.
Moving Averages 50-day and 200-day are the most important. Golden cross = bullish. Death cross = bearish. They lag the price.
RSI Above 70 = overbought. Below 30 = oversold. Use for confirmation, not standalone signals. Watch for divergences.
MACD Bullish crossover = MACD crosses above signal line. Histogram shows momentum strength. Best combined with RSI.
Volume Volume confirms price action. High volume = conviction. Low volume = weak move. Always check volume on breakouts.
