Candlestick Basics
Each "candle" on a chart represents one time period (1 day, 1 week, etc.) and shows four prices:
Reading a Candle
Open: The price when the market opened
Close: The price when the market closed
High: The highest price reached during the day
Low: The lowest price reached during the day
Think of each candle as a mini story of one trading day. The body tells you "who won" (buyers or sellers). The wicks tell you "how hard the fight was" (how far prices swung before settling).
A long green body = strong buying pressure. A long red body = strong selling pressure. Long wicks = indecision or reversal. Short body with long wicks = tug-of-war.
Common Candlestick Patterns
Certain candle shapes appear repeatedly and hint at what might happen next:
No pattern works 100% of the time. These are probabilistic signals, not crystal balls. Professional traders use patterns alongside other indicators and context — never in isolation.
For long-term investors: You don't need to memorize dozens of patterns. Understanding the basic candle anatomy (KP1) is enough. The patterns above are "nice to know" — they won't change your buy-and-hold strategy.
John Murphy's Technical Analysis of the Financial Markets: The definitive reference for chart patterns. Over 500 pages — but for most investors, the first 3 chapters cover 90% of what you need.
Volume: The Crowd Behind the Move
Volume is the number of shares traded during a time period. It answers: "How many people participated in this price move?"
Volume Rules of Thumb
Price up + high volume = healthy rally, likely to continue
Price up + low volume = weak rally, might reverse
Price down + high volume = strong selling, could continue falling
Price down + low volume = could be a shakeout, might bounce
Volume is like votes in an election. If a candidate wins with 90% turnout, it's a mandate. If they win with 10% turnout, it's a weak victory that might not stick.
Volume confirms conviction. A big price move on tiny volume is like applause from 3 people — not very convincing.
Moving Averages (MA)
A moving average smooths out daily noise to show the trend direction. It calculates the average closing price over the past N days.
Common Moving Averages
MA Period
What It Shows
Used For
MA5 / MA10
Very short-term trend
Day/swing traders
MA20 / MA50
Medium-term trend
Identifying trend direction
MA200
Long-term trend
Bull vs bear market indicator
Golden Cross & Death Cross
Golden Cross: Short MA (50) crosses ABOVE long MA (200) — bullish signal
Death Cross: Short MA (50) crosses BELOW long MA (200) — bearish signal
For long-term investors: The MA200 is the only one that really matters. If the S&P 500 is above its 200-day moving average, the long-term trend is up. That's it — you don't need to memorize every crossover pattern.
Support & Resistance
These are price levels where the stock tends to "bounce" or "stall":
Support: A price floor — the stock has bounced up from this level multiple times
Resistance: A price ceiling — the stock has been pushed back down from this level multiple times
Support is like a trampoline: prices bounce off it. Resistance is like a glass ceiling: prices keep hitting it and falling back. When the price finally BREAKS through resistance, it often becomes the new support (the ceiling becomes the floor).
For long-term investors: Support and resistance matter more for traders. If you're buying and holding for 10 years, these short-term levels won't affect your outcome. Nice to understand, not essential to act on.
MACD (Moving Average Convergence Divergence)
MACD measures momentum — is the trend speeding up or slowing down?
How to Read MACD
MACD above signal line: Momentum is bullish (upward)
MACD below signal line: Momentum is bearish (downward)
For long-term investors: MACD is a trading tool. If you're buying VOO and holding for 10 years, MACD signals won't improve your returns. Understand the concept, but don't trade based on it.
RSI (Relative Strength Index)
RSI measures how overbought or oversold a stock is on a scale of 0-100.
RSI Reading
Above 70: Overbought — stock might be due for a pullback
Below 30: Oversold — stock might be due for a bounce
Between 30-70: Normal — no extreme signal
RSI can stay above 70 for weeks in a strong uptrend, or below 30 for weeks in a crash. It's a hint, not a guarantee. Strong stocks can stay "overbought" much longer than you expect.
For long-term investors: Like MACD, RSI is mainly useful for traders. If you're dollar-cost averaging into index funds, RSI signals won't change your strategy. Worth understanding, not worth acting on.
How Charts Help Long-Term Investors
After learning all these indicators, here's the honest truth:
What Long-Term Investors Actually Need from Charts
Overall trend direction — Is the market generally going up over years? (Answer: historically, yes)
MA200 as a health check — If the S&P 500 is above its 200-day MA, the long-term trend is intact
Context during crashes — Charts showing historical recoveries help you stay calm
What Long-Term Investors DON'T Need
Daily candlestick analysis
RSI/MACD trading signals
Support/resistance day trading
Chart pattern prediction
Understanding charts makes you a more informed investor. But for a long-term buy-and-hold strategy, the best chart is the one you check once a quarter — not the one you obsess over daily.
John Murphy's Technical Analysis of the Financial Markets: Even Murphy himself acknowledges that technical analysis is most useful for timing decisions, not for evaluating the fundamental worth of investments.
