Technical Analysis Basics
Updated May 28, 2026 · Published May 13, 2026
Charts, trends, and indicators used to study price action.
Technical analysis (TA) studies price, volume, and derived indicators to infer how supply and demand may behave. Practitioners assume market action discounts much public information and that patterns repeat often enough to inform decisions.
TA does not replace risk limits or option math. It may help you choose strikes, direction, and timing when paired with defined-risk structures.
Core beliefs (stated neutrally)
- Price reflects collective behavior.
- Trends can persist; ranges can mean-revert.
- Volume confirms or questions moves.
- History rhymes; it does not repeat perfectly.
Critics note data mining and self-fulfilling levels. Many traders still use charts as a common language.
Chart types
| Type | Shows |
|---|---|
| Line | Closing prices; simple trend view |
| Candlestick | Open, high, low, close per period |
| Volume bars | Activity under price |
Daily charts are standard for swing traders; intraday charts matter for short-dated options.
Trends and ranges
Uptrend: series of higher highs and higher lows.
Downtrend: lower highs and lower lows.
Range: price oscillates between support and resistance.
Support and resistance names where price has stalled before.
Common tools
- Moving averages: smooth noise; see Moving averages intro
- RSI: overbought/oversold oscillator (can stay extreme in trends)
- MACD: momentum crossovers
- Volume profile: where most shares traded (advanced platforms)
No indicator works every time. Combine with context (earnings, macro).
TA and options together
| TA idea | Options implication |
|---|---|
| Bullish trend | Calls, bull spreads; avoid fighting trend with naked short calls |
| Range | Iron condors, short strangles (advanced, high risk) |
| Breakout expected | Long straddle/strangle; pay theta |
| Support hold | Sell put at support (assignment risk) |
Expiration adds a clock. A correct directional view with wrong timing still loses on long premium.
Process sketch
- Identify trend or range on higher timeframe (weekly/daily).
- Mark support/resistance.
- Pick strategy in ThetaViz builder matching thesis and max loss.
- Size position per risk management.
Limitations
- Charts lag; they describe past prints.
- Gaps ignore intraday levels.
- Low-float stocks distort patterns.
- TA on IV is separate from TA on price, use the chain for IV.
Worked example: daily trend, weekly filter
Daily chart shows higher lows for six weeks (uptrend). Weekly chart still below a falling 50-week average (longer-term repair).
- Bullish swing trader might buy calls with 30–45 DTE aligned with daily trend.
- Bearish longer-term trader might fade rallies into weekly resistance.
Timeframes conflict often. Write which timeframe governs your trade.
Worked example: range and iron condor
$90–$110 range for three months. You model an iron condor with short strikes outside the range.
- Breakout above $110 with volume invalidates the range thesis.
- TA is for context; max loss on the chart is the hard number.
Volume confirmation
A breakout candle on 3× average volume carries more weight than a drift on thin volume. Options OI at the breakout level can show where dealers hedged.
Avoid indicator soup
Five oscillators saying buy while price makes lower highs is noise. Pick two tools (for example structure + 50-day MA) and log outcomes.
Higher timeframe discipline
Many traders mark weekly levels, then execute on daily or 4-hour charts. Options DTE should match the timeframe of the setup, not only the chart you like looking at.
Macro and TA together
Fed day can invalidate a perfect triangle. Note macro calendar when you sell premium into tight ranges.
Backtesting caution
Testing indicators on past data is easy to overfit. Out-of-sample years and simple rules beat perfect curves on one bull market.
Builder workflow recap
Mark trend on chart → pick strategy in /build → set max loss you accept → compare delta if directional. TA picks the zone; options math picks the instrument.
Journal one sentence per trade
Write: "I traded because the chart showed X at level Y." Later, label wins and losses that followed process vs impulse. TA improves when you review charts, not when you collect more indicators. One screenshot per trade is enough.
Paper first, size second
Use ThetaViz to model the option structure that matches your chart thesis before you fund the trade. The chart picks the idea; the builder shows dollars at risk.
