Technical Indicators

Indicators transform price and volume into another view of the same data. Learn what they measure—and how to keep them from cluttering your chart.

What you will learn

  • What indicators actually calculate
  • Trend, momentum and volatility types
  • Common tools: MA, RSI, MACD, ATR
  • Lag, noise and overlap
  • A simple indicator stack
  • How to test indicator rules

Indicators Are Derived Views

Almost every indicator is built from past price (and sometimes volume). They do not “see the future”—they summarise history in a formula so you can compare periods more easily.

That means indicators lag by design. The trade-off is clarity: a moving average can make a noisy series easier to read, but it will react after price has already moved.

Three Useful Categories

Trend

Moving averages, ADX and similar tools help describe direction and whether a move is sustained.

Momentum

RSI, MACD and oscillators measure speed and strength of recent moves—often used for overbought/oversold context.

Volatility

ATR and Bollinger-style bands describe how wide price typically swings—useful for stops and position sizing ideas.

Starter Indicators to Understand

  • Moving average (MA / EMA) — smooths price over N periods. Crossovers and price-vs-MA are common study rules; none work in every market regime.
  • RSI — scales recent gains vs losses into a 0–100 range. Extremes can mean stretched conditions—or strong trends that stay “overbought/oversold” for longer.
  • MACD — compares two moving averages and a signal line. Often used for momentum shifts; can whip around in ranges.
  • ATR — average true range. Helps estimate typical movement so risk distances are less arbitrary.

Keep the Chart Readable

  • Prefer one tool per job—don’t stack five momentum indicators that say the same thing
  • Read price structure first; use indicators as confirmation or filters
  • Know that settings (period length) change behaviour—default is not sacred
  • If removing an indicator doesn’t change your decision, you probably don’t need it

Test Indicator Rules Before You Trust Them

“Buy when RSI crosses 30” sounds simple until you measure win rate, drawdowns and behaviour across trending vs ranging markets. BRBStox Backtesting Lab and Market Replay let you define rules, run them on history, and review decisions without risking capital.
