Technical Indicators Explained: RSI, MACD, Moving Averages & More

Technical indicators are mathematical transformations of price (and sometimes volume) designed to make a particular feature of the market easier to see — trend, momentum, or volatility. They don't predict the future; they summarise the past in a useful way. Used well, they bring structure to a chart. Used badly — piled ten-deep until they all "agree" — they just manufacture false confidence. Here are the ones that matter and how to read them honestly.

Trend indicators

Moving averages (MA)

A moving average is simply the average price over the last N periods, recalculated each bar. It smooths out noise to reveal the underlying direction.

• A rising MA suggests an uptrend; a falling MA, a downtrend.
• Price above a long MA (e.g. 200-period) is broadly bullish context; below it, bearish.
• Crossovers — a shorter MA crossing above a longer one — are a classic (if lagging) trend signal.

The trade-off is lag: because they average the past, MAs react slowly. Shorter MAs are more responsive but noisier; longer MAs are smoother but slower. We cover these in depth in the moving averages section of the app.

Momentum indicators

RSI (Relative Strength Index)

RSI measures the speed and size of recent price changes on a 0–100 scale. Traditionally:

• Above 70 = "overbought", below 30 = "oversold".

But here's the honest caveat most beginners miss: in a strong trend, RSI can stay overbought or oversold for a long time. "Overbought" does not mean "about to fall." RSI is most useful for spotting divergence — when price makes a new high but RSI makes a lower high, momentum is fading even as price rises, which can warn of exhaustion.

MACD (Moving Average Convergence Divergence)

MACD measures the relationship between two moving averages, plotting the difference as a line with a signal line and a histogram. It's read for:

• Crossovers of the MACD line and signal line (momentum shifting).
• The histogram expanding (momentum building) or contracting (fading).
• Divergence against price, like RSI.

Volatility indicators

Bollinger Bands

Bands plotted a number of standard deviations above and below a moving average. They expand when volatility rises and contract when it falls. Price tends to spend most of its time within the bands; a "squeeze" (very narrow bands) often precedes a larger move, though it doesn't tell you the direction.

ATR (Average True Range)

ATR measures how much an instrument typically moves per period — pure volatility, no direction. It's invaluable for risk management: a sensible stop-loss on a high-ATR instrument like Gold needs far more room than on a low-ATR pair. Sizing stops by ATR rather than a fixed number is one of the most practical uses of any indicator (see our risk management guide).

Support, resistance and pivots

Not indicators in the formulaic sense, but the levels traders watch most:

• Support — a price area where buying has previously emerged.
• Resistance — where selling has previously emerged.
• Pivot points — calculated levels derived from the prior period's high, low and close, widely used as intraday reference points.

These matter because they're self-fulfilling: so many participants watch the same levels that price genuinely reacts to them.

The cardinal rule: confluence, not clutter

The mistake that ruins most beginners is indicator stacking — adding RSI, MACD, Stochastics, three MAs and Bollinger Bands until something always points the way they want. Because many indicators are derived from the same price data, they're correlated; having five momentum tools "agree" is not five pieces of evidence, it's one.

The professional approach is confluence across different dimensions: a trend tool, a momentum tool, and a key level lining up. One of each, telling a coherent story, beats ten of the same kind.

How TradeVisor uses indicators

TradeVisor's deterministic technical engine computes 50+ indicators across multiple timeframes — but it doesn't just count how many are "bullish." It assesses trend, momentum and volatility as distinct dimensions, identifies key levels, and feeds that structured picture to the technical agent. The result is read for genuine confluence, not noise.

The bottom line

Indicators are lenses, each clarifying one aspect of price. Learn what each actually measures, respect their limits (especially RSI in trends and the lag in moving averages), and look for confluence across different types of indicator rather than agreement among similar ones. The chart is the evidence; indicators just help you read it.
