Technical Indicators: RSI, MACD, Moving Averages

Technical indicators are formulas that turn past prices, and sometimes volume, into lines or histograms that are easier to read than raw candles. Each one answers a specific question: is the market trending, how strong is the move, is price stretched, is volatility rising? In technical analysis for beginners, four tools cover most of what you need: moving averages, the RSI indicator, MACD and Bollinger Bands. All of them are calculated from prices that have already happened, so they describe the market; they do not predict it.

The main families of indicators

Knowing an indicator's family tells you what its reading can and cannot say:

Trend indicators show direction: moving averages, Parabolic SAR and DMI.
Momentum oscillators measure the speed of moves within a range: RSI, MACD, KDJ (Stochastic), Williams %R, CCI, Momentum and Rate of Change.
Volatility indicators show how widely price swings: Bollinger Bands.
Volume indicators look at the activity behind a move: Volume and On Balance Volume. Forex has no central exchange, so volume on any chart reflects only what its data source records.

Two indicators from the same family usually tell you the same thing twice. One trend tool plus one oscillator is a clearer start than five oscillators stacked on one chart.

Moving averages: MA and EMA

A simple moving average adds the closing prices of the last N periods and divides by N. If EURUSD closed at 1.1500, 1.1520, 1.1510, 1.1540 and 1.1530 over five days, the 5-day average is 5.7600 ÷ 5 = 1.1520. Each new day drops the oldest price and adds the newest, so the line follows the market more smoothly.

The exponential moving average (EMA) gives more weight to recent prices, with a multiplier of 2 ÷ (N + 1). For a 20-period EMA that is 2 ÷ 21, about 9.5% of the weight on the latest close, so it reacts faster than a simple average of the same length.

Price above a rising average suggests an uptrend; below a falling one, a downtrend.
A fast average crossing above a slow one, such as the 50-day over the 200-day, is read as a shift in trend.
In sideways markets averages lag and produce repeated false crossovers.

RSI: the Relative Strength Index

The RSI indicator, introduced by J. Welles Wilder in 1978, compares the size of recent gains with recent losses on a scale from 0 to 100. Its classic setting is 14 periods:

RSI = 100 − 100 ÷ (1 + RS), where RS is the average gain divided by the average loss.
Average gain 30 pips and average loss 15 pips: RS = 2, so RSI = 100 − 100 ÷ 3 ≈ 66.7.
Average gain 45 pips with the same loss: RS = 3, so RSI = 100 − 25 = 75, above the 70 level.

Readings above 70 are called overbought and below 30 oversold, but that does not mean price must turn: in a strong trend RSI can stay above 70 for a long time. Many traders find divergence more useful, when price makes a new high but RSI makes a lower one, a sign that momentum is fading. A shorter period makes RSI more sensitive and sends it to 70 or 30 more often; a longer one smooths it.

MACD: Moving Average Convergence Divergence

MACD, developed by Gerald Appel in the late 1970s, is built from two exponential averages. With the standard 12, 26, 9 settings:

MACD line = 12-period EMA − 26-period EMA.
Signal line = 9-period EMA of the MACD line.
Histogram = MACD line − signal line.

Example: if the 12-period EMA of EURUSD is 1.1540 and the 26-period EMA is 1.1525, the MACD line is 0.0015, or 15 pips. With the signal line at 0.0010, the histogram is +0.0005: upward momentum is currently stronger than its recent average.

Traders watch the MACD line crossing its signal line, the MACD line crossing zero (which happens when the two averages cross), and divergence from price. Because it is built from averages, MACD lags, and in quiet ranges its crossovers are frequent and unreliable.

Bollinger Bands

Bollinger Bands, created by John Bollinger in the 1980s, place a band two standard deviations above and below a 20-period simple moving average. Example: with the middle band at 1.1500 and a standard deviation of 15 pips (0.0015), the upper band is 1.1500 + 2 × 0.0015 = 1.1530 and the lower band 1.1500 − 0.0030 = 1.1470, a channel 60 pips wide.

Narrow bands, often called a squeeze, mean low volatility and often come before a larger move, though they do not reveal its direction.
Wide bands follow sharp moves.
Touching a band is not a signal by itself: in a strong trend price can ride along one band for many candles.

How to combine indicators without overload

A clean method uses one indicator to define the trend, another to time the entry, and price action as the final judge. For example, on H4: price holds above a rising EMA, RSI dips towards 40 to 50 and turns up, and the MACD histogram turns positive. That is a setup worth studying, with a stop below the latest swing low and a size set by the rules in risk management. Confirm signals with the candles themselves, see how to read candlestick charts, and check the economic calendar, because major news can override any indicator.

A note on risk

Indicators are built from past prices and do not predict the future; every signal fails some of the time. CFDs are leveraged, so losses can grow fast and you can lose your whole balance. Trade only money you can afford to lose, and read the risk disclosure first.
