Technical analysis is the study of a security's price and volume history to identify patterns, momentum, and probabilities about future price movements. It is not about predicting the future with certainty โ no method can do that โ but about identifying conditions where the probability of a particular outcome is meaningfully higher than average.
This guide focuses on two of the most widely used technical indicators in the world: RSI (Relative Strength Index) and MACD (Moving Average Convergence Divergence). Each chart below shows exactly how these indicators look on a real price series โ not abstract theory, but the actual signals you will see on screen.
Technical and fundamental analysis are complementary. Fundamental analysis tells you what to buy. Technical analysis tells you when to buy it.
The formula calculates the ratio of average gains to average losses over the past 14 periods. If the stock has risen strongly and consistently, RS is high and RSI pushes toward 100. If it has fallen hard, RSI drops toward 0. The indicator always oscillates between 0 and 100.
RSI above 70 โ Overbought: The stock has risen strongly relative to recent history. However โ and this is the most important thing to understand โ overbought does not mean "sell now." In a strong uptrend, RSI can stay above 70 for weeks or months. Overbought is a caution flag, not a sell signal.
RSI below 30 โ Oversold: The stock has fallen sharply. Again, oversold does not automatically mean "buy now." In a strong downtrend, RSI can remain below 30 as selling continues.
The chart below shows exactly this โ a stock in a clear uptrend where RSI stays elevated above 70 for an extended period. A trader who sold every time RSI crossed 70 would have missed the entire move.
โ ๏ธ The shaded orange zone shows where RSI is above 70 (overbought). The price kept rising throughout. Selling at the first overbought signal would have meant missing a 28% gain.
The most valuable RSI signal is not the absolute level, but divergence โ when price and RSI move in opposite directions. Divergence tells you that the momentum behind the current price move is weakening, even though price has not yet reversed.
Bullish Divergence: Price makes a new lower low, but RSI makes a higher low. Even though price fell further, the selling momentum behind that fall was weaker. The market is running out of sellers โ a potential reversal upward.
Bearish Divergence: Price makes a new higher high, but RSI makes a lower high. The buying momentum behind the new high was weaker than before. The market may be running out of buyers โ a potential reversal downward.
โ The green arrows show where the divergence signal formed. Price eventually reversed and rallied strongly from the final low โ the RSI had been warning this was coming for several weeks.
The MACD Line measures the gap between short-term and long-term momentum. Positive = short-term momentum stronger than long-term (bullish). Negative = long-term momentum dominates (bearish).
The Signal Line is a smoothed average of the MACD Line. When the MACD Line crosses above the Signal Line, it is a bullish signal. When it crosses below, it is bearish.
The Histogram shows the gap between MACD Line and Signal Line as bars. Growing bars = accelerating momentum. Shrinking bars = fading momentum โ often an early warning of an upcoming crossover.
๐ Watch the histogram bars shrink toward zero before the crossover happens โ this is the earliest warning of the momentum shift, often 2โ3 days before the MACD line actually crosses the signal line.
Bullish Crossover: MACD Line crosses above the Signal Line. Short-term momentum is strengthening. BUY SIGNAL
Bearish Crossover: MACD Line crosses below the Signal Line. Selling pressure is strengthening. SELL SIGNAL
Zero Line Cross: When MACD crosses above zero, the 12-period EMA has crossed above the 26-period EMA โ the short-term trend is now above the long-term trend. A bullish structural signal.
Histogram shrinking: Even before a crossover, watch the histogram bars getting shorter. This is your earliest warning. EARLY WARNING
Using RSI and MACD together dramatically improves signal quality. The principle is confluence: when two independent indicators point to the same conclusion simultaneously, the probability of a genuine signal increases substantially. One indicator alone can produce false signals. Two indicators agreeing filters most of them out.
โ At day 18, both signals fired simultaneously: RSI showed bullish divergence AND MACD produced a bullish crossover. Price rallied 22% from that point. Neither signal alone would have been as convincing.
If RSI is oversold (suggesting a potential buy) but MACD is in a strong downtrend with no sign of a crossover โ the signals conflict. The right response is to wait. Acting on conflicting signals is one of the most reliable ways to take unnecessary losses. Patience until confluence emerges is what separates consistent technical traders from impulsive ones.
Add a third dimension to make RSI and MACD signals far more reliable: the direction of the long-term trend, measured by the 200-day moving average (200-DMA).
Fintiq's Technical tab applies this entire framework automatically to any stock across global markets. Enter any ticker โ BP, Lloyds, Apple, NVIDIA โ and the platform instantly displays:
You do not calculate any of this manually. The platform does the computation instantly, so you focus on interpreting signals rather than arithmetic.
Open Fintiq and navigate to the Technical Analysis tab. Pick three or four stocks you already know โ companies in the news or in your portfolio. For each one, ask yourself: Is RSI confirming or diverging from the price trend? Is the MACD histogram growing or shrinking? Is the stock above or below its 200-day moving average?
You do not need to trade based on this โ just practice reading the charts. After two weeks of daily observation, the patterns in Charts 1โ4 above will start jumping out at you on real data. That's when technical analysis becomes genuinely useful as a timing tool on top of your fundamental research.
Fintiq's Technical Analysis tab calculates RSI, MACD, Bollinger Bands and Moving Averages automatically for any global stock. Free to use.
