Technical Analysis Essentials

Lesson 1: Candlestick Anatomy

A candle shows four prices for a time period: open, high, low, close.

• The body is the box between open and close. Green/white = close above open (bullish). Red/black = close below open (bearish).
• The wicks (shadows) show the high and low reached during the period.
• Long lower wick + small body = buyers rejected lower prices. Long upper wick = sellers rejected higher prices.

One candle tells you almost nothing. Three candles in context tell you a story. Beginners memorize 60+ candlestick names; professionals read the story of who is in control — buyers or sellers.

Lesson 2: Trends and Trendlines

A trend is the direction of the overall move:

• Uptrend = higher highs + higher lows.
• Downtrend = lower highs + lower lows.
• Range = price bouncing between support and resistance with no clear direction.

Trendlines are drawn by connecting two or more swing lows (uptrend) or swing highs (downtrend). They are descriptive, not predictive. A trendline break does not mean reversal — it means the trend is weakening and you should pay attention.

"The trend is your friend" is a true statement, but only up to the point where it ends. Your job is to ride it, not to marry it.

Lesson 3: Support and Resistance

Support = a price level where buyers have repeatedly stepped in. Resistance = a level where sellers have repeatedly stepped in.

Key principles:

• The more times a level is tested, the more "valid" it looks — but also the more likely it is to break (every test weakens it).
• Old resistance, once broken, often becomes new support (and vice versa). This is polarity.
• Round numbers (e.g. BTC at $100,000) often act as psychological levels.

Support and resistance are zones, not lines. Draw them as shaded areas, not razor-thin lines that price "must" respect to the penny.

Lesson 4: Moving Averages (SMA & EMA)

A moving average smooths price into a single line so you can see direction without noise.

• SMA (Simple) = average of the last N closes, equal weight.
• EMA (Exponential) = weighted toward recent prices. Reacts faster to new moves.

Common settings:

• 20/21 EMA — short-term trend.
• 50 SMA — medium-term trend.
• 200 SMA — long-term trend. Price above 200SMA = bull regime; below = bear regime.

The classic moving average crossover (e.g. 50 crossing above 200 — a "golden cross") signals trend change. It is lagging by design. Use it as confirmation, not as your only signal.

Lesson 5: Chart Patterns

Patterns are shorthand for the psychology of buyers and sellers. The ones that actually matter:

• Double top / double bottom — price tests a level twice and fails. Reversal signal.
• Head and shoulders — three peaks, middle is highest. Reversal signal.
• Flag / pennant — brief consolidation after a strong move, then continuation.
• Triangles — price coils into a narrowing range; direction breaks out.

Most patterns are just support/resistance in disguise. If you understand S/R, you understand 80% of patterns without memorizing names.

Pattern traders who memorize 30 shapes lose money. Pattern traders who understand "buyers failed twice at this level" make money. Same pattern, different outcome.

Lesson 6: Indicators or Overload?

Indicators are math applied to price. They can help — or they can give you false confidence.

Two categories:

• Trend indicators (MA, MACD, ADX) — work in trending markets, whipsaw in ranges.
• Oscillators (RSI, Stochastic, MACD histogram) — measure overbought/oversold, work in ranges, bleed in trends.

The classic beginner error: stacking 6 indicators on a chart, looking for the moment they "all agree". They never will. Pick one trend indicator + one oscillator and learn them deeply.

Indicators are tools, not oracles. Price first. Structure second. Indicators third.
