Technical Indicators Explained: RSI, MACD and Moving Averages

Indicators can clarify a chart or clutter it. Master these three essentials and you have everything most traders ever need.

Bar chart for technical indicators RSI and MACD

Technical indicators are calculations plotted on a chart to help you read momentum, trend and timing. You only need a few.

1. Moving averages (trend)

A moving average smooths price into one line, revealing the trend. A short MA crossing a long one is a “golden cross” (bullish) or “death cross” (bearish).

Key idea: Indicators are lagging by nature — they describe what price has already done. Use them to confirm, not predict.

2. RSI (momentum)

The Relative Strength Index runs 0–100. Above 70 is “overbought,” below 30 “oversold” — but in strong trends RSI can stay extreme for a long time.

3. MACD (momentum + trend)

The MACD compares two moving averages to show momentum shifts, and is great for spotting divergence.

Don’t overload your chart

Pick one trend tool and one momentum tool, learn them deeply, and combine with price action.

Key takeaways

  • Moving averages reveal trend; RSI and MACD read momentum.
  • Indicators lag — confirm, don’t predict.
  • Overbought/oversold are clues, not signals.
  • Two well-understood indicators beat ten you half-know.

Frequently asked questions

What are the best technical indicators for beginners?

A moving average (trend) plus RSI or MACD (momentum). Learn two deeply rather than stacking many.

What does RSI above 70 mean?

It suggests overbought conditions, but in a strong uptrend RSI can stay above 70 for a long time — treat it as a clue, not an automatic sell.

Do technical indicators actually work?

They help read momentum and trend, but they lag price. Use them to confirm setups alongside support/resistance, not in isolation.
